Bluetooth Headset for XDAII - Your opinions please

Hi People,
I'm looking to get potentially 3 Bluetooth Headsets for XDAII (for staff)
And I don't want any moaning once I get them that the quality is bad
Could you post your personal experiences of ones you have purchased and are using please. Would like some recommendations if possible.

I have a Sony-Erricsson HBH-35. Works like a charm.
No rebonding, it reconnects wether you'r out of range, the phone or headset has been switched off etc...

I have a Motorola HS810.
It's nice and small (even with the boom open). The audio quality is excelent. However, what really nags me is that it takes too long to boot the device when you open the boom, so that in most occasions it takes too long to connect to the XDA and I can't pick up a call in time.
Also, sometimes it simply doesn't connect to the device after I pick up a call on the XDA and I can't transfer the call to the headset.
Anyone with the same problems with this headset ?

My HBH65 works absolutely perfectly with the XDA2. Original XDA2 radio & Bluetooth stack - just as it came out of the box. I *never* need to rebond the two devices, even if they're switched off, out of range or whatever, and I can walk around my (small) house using the headset and leave the XDA2 on the desk.
Only criticism is the battery life on the HBH65, which is pants. I have to charge it every other day, at best, without much useage.
Still, it's *very* comfortable and the sound quality and volume is good in quiet environments. In the car it's a struggle, but that could be because I have a car with a 6 litre engine and no exhaust silencers...

I have a Jabra 250
Works perfect, never any bonding, or lost call problems, and as set 250 minutes of standby time, very small, and looks really smart. After I bought one, my wife wanted one too.

Thanks for the response all, much appreciated !
I opted for the Sony-Erricsson HBH-35
I got them from expansys and got them the next day! .... they are great. The call quality is excellent. I think the boom helps to eliminate background noise as the mic doesn't have to be too strong.
Now i just need to go to the "using it" forum to find out how to use voice dialing :s

Logitech BT headset is the best !

I really like the Bluespoon Cameleon. Works very well. Only about $100. Much less obtrusive than other Bluetooth headsets. You can change it's colors, which is cool. It's much smaller and lighter than other headsets as well.
It was so good, that I thought I'd go one step further and get the Bluespoon Digital, which I just started using. The Bluespoon Digital seems to get the call transferred instantly (quicker than the Cameleon), and it's about the size as the end of my thumb.
I havn't had the chance to try out the automatic gain control (changes volume of speaker based on ambient noise), or the digital noise cancellation (blocks out slow moving ambient sound).. but those features sound mighty nice!

About bluespoon, I have a pb, seems really good when I make a call but impossible to use it when i receive a call, no transfer to the headset

What's a pb? With the Bluespoons, you press a button on the headset to transfer the call to it.

really doesn't work, dunno why !!!!!
If you have an advice, I'll really appreciate it

HB 35
I too Have the sony ericsson hb 35 top h/set well worth the investment

Did you try a hard reset of the Bluespoon? Also a soft reset according to the instructions in the manual? After a soft reset you'll have to recreate the bond.

Plantronics M3000 is the best one I could fine. Everyone would always tell me they couldn't hear me. The M3000 sounds very clear, connects as a Bluetooth Device and battery life is around 2 days.
Very small around the ear, no cords, or mess. I like it.

Best ROM for stereo Bluetooth??

Hey guys I currently have a Tilt running alex's stripped rom with radio 1.27.14.09. I love the rom as its been the fastest i have tried however I recently bought a motorola s9 stereo bluetooth headset for music and i'm getting lags in play back. For example if i have it on my belt clip it will cut in and out periodically but if i leave in on the table and walk 25 feet away it will work fine. Just weird stuff like that. Is there a better rom out there for stereo bluetooth playback??
thanx

This is what I put in my Rom for best "quality". (W/ joint stereo and bitpool disable, and 48000 sample bit rate). Works fine w/ my JVC BT-1 and Sony DS220.
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings]
"USEJOINTSTEREO"=dword:0
"SampleRate"=dword:BB80

Correct, these are the same settings that I use as default for my ROM and works well with my S9. Although I still can occasionally have the cut out you describe these settings seem to make it much rarer.

i just recently got some s9's and i love them. same settings and everything!
only one problem though, when wlan is turned on i get the cutting out. when it is off everything is fine. any ideas?

I don't personally have this problem...but it shouldn't be surprising...802.11b is probably what you're using and it traditionally has a lot of interference issues with Bluetooth. You might want to try setting your WLAN to "best battery". You probably won't really be able to change the type of base station you're connecting to if its one at work when you have the issue so that's about the only advice I can give.

Because both of them is around the 2.4Ghz frequence range (just like yr mirco wave oven).

But ... according to this article ... "Menneisyys" advised to set the key to "1"
http://www.pocketpcmag.com/blogs/index.php?blog=3&p=2004&more=1&c=1&tb=1&pb=1#more2004
quotes:
""As a rule of thumb, if a given ROM version supports Joint Stereo, then, it’s capable of delivering pretty good A2DP quality. That is, if, in the Registry, the value HKLM\Software\Microsoft\Bluetooth\A2DP\Settings\UseJointStereo (note that HKLM, as usual, stands for HKEY_LOCAL_MACHINE) is 1 , meaning enabled (NOT 0, meaning disabled) and the sound is (still) stereo, then, you have the new, WM6-based, high-quality A2DP implementation."""" ...
~~
""Don’t forget than in pre-WM6 times you HAD to disable the Joint Stereo mode; therefore, if you have ever run automatised sound quality enhancer tweaks (for example, with the excellent HTweakC tool) , they may have already set this to 0 (which isn’t recommended any more)."" ...
~~~

What bluetooth headset are you using and how is your bluetooth strength?

I use jabra and if I have the phone in my pocket, the sound gets tons of static, my a2dp headset tends to skip when the phone is in my pocket, out of the pocket it works perfectly, if I put the phone behind me, thus my body is in between the headset and the phone, i also get tons of static even though the distance is 20 inches.

I tested my 3125 smartphone against the Touch cruise and the 3125 range was three times farther then the touch cruse. Back to mobileplanet this heap of **** goes.

The radio stack on the test ROM makes a HUGE difference

I have the same issue even with the new radio--bluetooth strength much weaker than my old trinity. Wonder if there is a registry setting to boost the signal?

this phone is brutal, with 3g and bluetooth on, I drop calls like no tommorrow,it seems when driving it is even worse. I seen it where it has perfect signal and for no apparent reason, it drops the call. It just gives me three faint beeps when it disconnects. I don't know what it means, also these phones are not assembled well. this sucks for 700 dollar phone, I did try the new radio also, it didn't make no difference other then I didn't get disconnected on 3g as much but bluetooth still sucked, my 3125 I measured again has 3 times the range,just having your hand in between the phone and the headset gets you lot of static on the headset. I sent mine back today. Bluetooth is critical to me,I figure HTC would at least get the bluetooth right but I guess they are a mess right now with all their issues. Hoping to get hp 614 instead.

I am using the Jabra BT3030, works like a charm. This is with the default rom.

Plantronics Explorer 510 here. Absolutely perfect sound.

Parrot MK6100 car HF set. Crap, thin sound reported on the other side. Low volume.

To be more specific- both sony ds200 and itech r35 have good sound, no static but the range is very poor and easily blocked by a human body. The sony sound is much better probably because its bluetooth 2 with a better data rate. The a2dp (only with the sony) needs the "a2dp fix" and a fresh reboot before using in order not to have the drop outs. All told, not much different than with my trinity but with less range. Very disappointing considering price and another year to perfect the system. HTC really does need to work on the drivers and software before selling the device. The average user is not going to go to all this trouble and will be very letdown.

Issues with SE MW600

Hi,
I recently bought this nice bluetooth earphone (Sony Ericsson MW600) - because it was mentioned, it works great on Nexus One.
But I got a somehow strange problem:
when it is connected to the phone (at least, bluetooth settings say so), I can phone with this headset but I cannot listen to any music.
Settings say, it's connected to phone and media.
I tried enomthers and cyanogens latest roms.
Has anybody any idea, what is wrong?
edit: tested it with a SE v640i - works perfektly - must be an issue with the nexus/rom/whatever :-/
Thanks,
bastie

how did you buy them?

via ebay
it is unused and the package was not opened, too...

okay, after searching through the net for several hours - here's the solution:
it does not work, when wireless lan is turned on - for whatever reason
so:
first turn off wireless lan
then connect mw600 and play music
seems like bluetooth and wlan are blocking each other

Good to know. I just ordered one for 50 bux shipped when I preordered from mobilecityonline.com, which still is selling for the same price but now shipping is no longer free because it's no longer a preorder item. I figured its better than retail or ebay after my stint with a fake SE product a few years back. Thanks for the info!

One thing I learn is never buy bluetooth headsets or memory cards from ebay. 99.9% of them are fakes.

Hello Everyone,
kpjimmy, I ordered and received my MW600 from mobilecityonline.com too. They seem to have nice service.
How can we tell if we got a counterfeit device or not. I had problems in the past with serveral brands?
Did you find the instruction in the box were not detailed ?
I went to sony ericsson support page for the MW600, no user guide pdf file. Only the warranty pdf. I noticed for the other devices such as the DS205,DS970,DS980 there are user guide pdf files. Have you found one for the MW600?
Must say, I am impressed with the battery life. I took out of the box, charged for 8 hours as per instructions. Turned it on, paired it, turned on the FM radio with 100% volume. It went 10.75 hrs, even a few phone calls before dead. Did 3 full 8 hrs charges/10.75hrs to full discharges cycles.
Thank you,
Monnie

I have used the headset for a week or so and I must say it is an awesome little headset for the cash! I also have the plantronics 590A but that is for my personal home use, but the MW600 is great for the office or when you are out and about. I haven't taken any calls with the headset yet though.
As for this being possibly a fake headset? I have to say my last 'fake' headset was in the box, (wasn't sealed btw) and when used, the sound was too tinny like cheapo headsets you get at your local convenience store. This one I received from Mobilecityonline, in my opinion the real deal. The sound is nice and functions as it should. Very satisfied with the headset.
Anyone want a aliph icon? LOL kiddin...that's what I use when in the car.

Jimmy you work for SE? you haven't take any calls yet? and you used it for so long? or do you work for mobilecityonline.com? let me know what is your deal?

I hace one and very annoying problem with this headset . When i plug id to HD2 and turn on the WIFI , music freeze for a less then second and sound geting disorted and very thin (it sound like the music change frequency to very low. Anyone had this problem ?

I don't work for either. I am a BT and tech junkie . I have taken a call on the MW600 and all sounds fine and works great as expected. I have since use my Aliph Icon with the new A2DP drivers installed.
However, I also have gotten the BlueAnt S4. I have used this more than the MW600 and I have to admit I love the thing. It is truely handsfree and the sound is great, clear, loud and is truly handsfree.

You plug in? The MW600 does not need to be plugged in. The HD2 has A2DP. All you need to do is turn on your bluetooth and pair the phone with the headset. When you play the music with your bluetooth on, the phone should automatically connect to the headset and play wirelessly, no plugging in necessary. Please give us additional detail. Thanks!

my mw600 works great - 5.0.5.3 through froyo.

so the skip forward/back and play/pause buttons on this can control the music?
Because I've lost the original N1 remote and am looking for decent replacements.
Thanks

it controls music. display obviously doesn't show the track like it might if paired with a sony device however. touch volume slider is kinda annoying.

Same here !!!
Really annoying!
Just got it. Had a Nokia BH-103 before but it broke. On the Nokia the sound sometimes was getting faster or a bit slower from time to time but that did not annoy me that much, now i can hardly hear on song. even if i turn of wifi the issue remains. please please help. really was looking forward to use my new mw600 and now the expirence is ruined.
headset works great with ps3 and notebook even over "big" distance (can hear music in every room of my flat)
so i guess it's the devices fault
having a htc hero using villian rom 10.2
PLEASE HELP

SOLVED !!!!!
setting the cpu speed somehow messes up bluetooth audio transfare
disabled overclocking now works like a charm

I tried my friend's SE MH-100 which he uses for his Aino, but my N1 can't even find it via bluetooth. I ordered the MBS 200 which is a bluetooth speaker also from SE and I'm still waiting for it.
Any clue why it can't find the MH-100? Im afraid it wont be able to scan the MBS200's bletooth as well
UPDATE: It's working great

I ordered one from ebay just now because Sony Ericsson Canada is selling is for $99.99 (mobilecityonline sells it for $50 but charges $40 US for shipping too Canada...)
After reading stories about fake bluetooth, I am worried. How do I tell if the one I bought is genuine or not? I bought it from this seller: http://cgi.ebay.com/SonyEricsson-MW...ewItem&pt=PDA_Accessories&hash=item1e5cfdeebe

I purchased one from mobilecityonline in person.
I don't really like the volume control, but I encounter a pairing problem with nexus one.
If I keep the pairing with the phone, it works 100%, but if I connect it to another device, it refuse to connect to nexus one again except I pair them again.
The battery is awesome though, I play 8 hours of wireless music and the battery doesn't run out.

[Q] Nexus 5 Bluetooth and wired headset problems

Hello,
Pardon if this has been answered already, I simply did not find my exact question answered.
I am using my unmodified Nexus 5 (not even rooted), with the latest KitKat (v.4.4.2 build KOT49H) with quite a few wired and wireless headsets and people always complain they cannot hear me. Eventually I got my hands on an old Samsung Galaxy S2 and tried my best bluetooth headset with it: Imagine my surprise, I could hear myself quite clearly even when I was talking really really softly, barely above a whisper. My headset is excellent. My phone is not.
My questions revolve around what to do about it.
Nothing in KitKat allows me to adjust the bluetooth microphone gain, nor does it let me use an equalizer on my microphone. I can adjust the volume of the headset, but this does not do anything to the microphone gain.
So...
Question 1: am I the only person with this problem?
Question 2: what do you people do about it?
Question 3: are there any mods / custom ROMs out there that attempt to fix this problem? Google does not appear to be interested in doing so.
Thanks in advance!

*bump*
Any ideas? I have tried re-pairing my bluetooth headset - no go. I have tried flashing custom ROMs and kernels - no go again. It seems to be a problem with the phone, but I have no idea how to fix it. And Google searches always return other people having this problem. Noone with solutions, though.
Using a wired headset results in even worse results, if that were at all possible.
Has anyone tried to replace the bluetooth stack or driver with something that works?
Thanks!

*bump*
Yesterday I spent quite a few hours tinkering with my phone. I tried every last radio out there for the Nexus 5 and none had any effect on bluetooth microphone levels. Then I tried a few AOSP ROMs: CM11 and Omni. They turned out to be so closely related I might as well have just tried one. None had any effect on bluetooth microphone. Heck if CM11 doesn't do it, there really are no alternatives out there! I tried the FauxAudio tweak, even paid $2 to Faux, which successfully managed to do nothing: app didn't was written badly. Finally, I tried a bunch of volume boost tweaks. That worked, actually. That is, it boosted the wrong volume. Finally, in a moment of true and utter desperation, I opened an ADB shell and edited that mixer file by hand. I then discovered that microphone gain on bluetooth is not controlled there.
I tried all my wired headsets again: Etymotic HF3's microphone produces such an atrocious sound, if I am to rely on it I need to seriously consider becoming a mime. Then there were my Bose QC15 headphones with a remote cable for Android by some off-brand company: that was terrible, the cable is useless. Heck, not even mime lessons can help me there.
Eventually I chanced upon an old microphone cable for my QC15 headphones. Just microphone, no remote. Surprisingly, this one is loud and clear! That after being anything but loud or clear on my old cell phone. Interesting. Unfortunately, it's been out of production for a few years. My working theory is that Bose realized putting a decent microphone on expensive headphones gives people real value, makes them spend money, and that way lies madness. We can't have that, can we. So when that cable starts cutting, so does my use of this cell phone.
I am screwed.
In any case, I will stop bumping my own thread, you guys obviously don't know a solution or there would have been a lively conversation right now. And I am pretty sure there is a moderator or two frowning right now, possibly getting ready to throw an encyclopedia at me. My only hope is that Google is going to do something about that pesky Broadcom driver that doesn't work sometime before the mass exodus to the iPhone. And before my precious microphone cable stops working, or I will be leading the way for that exodus. It's a phone, damnit, if it doesn't work like one it's no good.
Hmmm.... it should be possible to wire a good lavalier mike on a cell phone cable... maybe I can get an op-amp from an old tape recorder to get decent amplification... When attaching a 9V battery on my headphone cable begins to look appealing, we really have a problem.

Yes, if nobody reply you is because no one can help u.
But for what it's worth, i had an Xperia Play for 2 years. Using an Motorola Bluetooth Headset H350 while driving and a MW600 Sony Ericsson Stereo Bluetooth Headset, both never had a problem.
Now from 2013 Christmas both headsets with my new N5: still never a problem and not noticing any low volume or mic. Sorry

same issue

No solution. I tried everything, everything I could think of. I got FauxAudio to work eventually and that did nothing for Bluetooth performance (and it said it wouldn't, but I was desperate).
I returned a lot of high end bluetooth headsets over this issue. Eventually I came upon the Plantronics Voyager Legend. I would like to tell you this really expensive headset works fine, but no - microphone gain is still low, though this time around people can hear me okay. Not great, just okay. I am using that now. It's not perfect, it's far from perfect, but finally usable. Sort of. If I speak loudly.
For what it is worth, the ElementalX kernel improves Bluetooth stability on the N5 quite a bit. Microphone gain is still low, though. Another thing that sometimes helps a little is turning off the multimedia profile on the headset, though why THAT would make a difference is beyond me.
All we can do is wait, watch the Samsung Galaxy S5 get released and wonder if we should switch.

My guess is either the bluetooth baseband or the bluetooth kernel driver used in the N5 is flaky. This is why I think so:
Problem does not exist on my old Samsung Galaxy S2, including when it runs the same nightly of CM11, nor does it exist on my computer or my desk phone. All the headsets I've owned performed admirably there, so the headsets are not directly the cause. From what I've seen no ROM and no kernel out there seem to be making a difference as far as Bluetooth gain is concerned, the problem is persistently there and the same. Best I could tell it's just the N5 with a problem and it's just for the phone profile. I've tried the Bose headset (the worst performer headset with the N5 of the lot) on a colleague's N5 and his phone was just as bad with it as mine. I am not sure if it's a small batch of N5s having a problem, I don't own lots and lots of N5 phones to try on, but I doubt it: with anything digital things are usually all-or-nothing and the N5 has an off-the-shelf Bluetooth chip, which is not unique to the N5. My guess is it's the entire model, but having only tried on 2 N5 phones, this is no more than a guess.
From what I saw online, the entire Nexus line has poor Bluetooth performance, not just the 5, and Google changed the Bluetooth stack with KitKat besides possibly introducing more problems. If you have a non-Nexus phone, the manufacturer most certainly replaced the Bluetooth driver and radio with one of their own, so problem goes away, but the Nexus line does not enjoy such attention.
An interesting thing to try would be for someone to put the LG G2 Bluetooth driver on a N5 kernel and try it out. I don't have the time or the expertise to do that, but there are plenty of people who do. Assuming the G2 does not have problems with bluetooth gain, if the problem still persists it will tell us if it's the N5 baseband or hardware doing it, and noone can help us there if that's the case.

I have this problem too, using my Nexus5 with iphone headsets. Peoples told me in skype and hangouts, that they hear me bad...

That's a different problem. The wired headset problem is easily solvable with FauxAudio and a supported kernel.

This maybe realted to the changes Google made to the core Bluetooth stack as of Android 4.3+ I know they made adjustments for the BLE [low poer Bluetooth devices like pedometers and other senor type crap]. It is BEYOND me as to why Google keeps adding functionality ot the core Bluetooth stack when it is GLARINGLY OBVIOUS they have real problems with Bluetooth as a whole. WHY NOT fix the core issues so Bluetooth is much better at the basics before trying to add functionality or more complex?
I know they complained it would cost a bit for a different newer Bluetooth license but I mean in my personal experience with many different phones Bluetooth is SUPER flaky even at it's best in Android, and does not even work the same way across devices [I have used 3 different Jabra speakerphones on my bosses Galaxy 3 recently and they all worked to varying degrees even though they all use the same version of Bluetooth protocol], but my T989 [Galaxy 2 T-mobile], my parents G2s My bosses older Bionic, My fathers new Droid X, etc. all have random problems. You can usually find one device that works well with a certain phone/ROM, but that can change between ROM versions and devices so it is like you need to go and buy 1 of everything every time there is an update and go crazy finding the ONE that works [and as noted on page 1 with the gentleman using the same Platronics Voyager Platinum as I have it is a super expensive very nice device that worked BEAUTIFULLY in ICS, but now in 4.1 + you can not get more than 1 or 2 words across the mic unless you are YELLING at it like a crazy person on the SAME device].
So all that to say I think it is prolly related to changes Android made in 4.3+ flipped the Bluetooth operability on it's head.

Mic Volume OK with KitKat 4.4.4 and cheap "HB-800" headset
there've been no posts for a while so maybe the problem has gone away with the KitKat updates.
But anyway:-
I have a Nexus 5 and recently bought a cheap generic stereo earbud headset with mic from eBay .... $14.82 Ozzie including delivery to Western Australia.
I've actually asked the other party whether they can hear me (specifically "am I loud enough?") because I read this thread and have been assured that it's all good.
In fact it's a pity the sound quality at MY end isn't better, but that's probably the low quality ear buds rather than electronics / firmware reasons.
Of course, ymmv.
Here's the ebay item title in case anyone wants to look it up or I can pm the item number if it helps.
"Headphones Earphones with MIC 1st Stereo Bluetooth Hands-Free Wireless HV/HB-800"

No, the problem is still there. Reason there are no posts is that no one has a solution. Nothing has changed since March. I am somewhat controlling it with CM11 running on the ElementalX kernel. Without this kernel Bluetooth performance is unbearable. With it it is barely adequate.
It's funny that a cheap headset would work okay while multiple top-of-the-line everything-but-the-kitchen-sink models like the Plantronics Voyager Pro would still be having problems.
I was seriously considering getting the OnePlus One, the Nexus 6 and even the iPhone 6 hoping the issue would finally be fixed. It's ridiculous that a phone commonly accepted as the measuring stick of the Android world would be having problems with simple tasks like driving a bluetooth headset. *very disappointed*

Me too. Two days with my new N5 and when I use my Sony SBH20 people hear me bad... With my N4 no problem. Its annoying! Ive to speak with headset because Ive problems with my left arm and legs, I only have the right to hold the phone, I cant do anyhing more and when I walk I need that arm to hold my cane.
I dont see a real solution, I will have to return the N5
