What's the deal with the headphone jack?

It seems the world and his dog are conspiring to prevent me enjoying music from my M500, to say nothing of the AD2P ferrago.
OK, so my M500 didn't come with any sort of handsfree kit, mono or otherwise. The goons at the local Orange shop tell me it only comes with a mono earpiece anyway, so no real loss there. I grabbed a cheap adaptor from a local shop, and it works, so long as you don't mind taking the phone out your pocket and whipping out the cable when a call comes in.
Turns out I do mind, so I set about looking for an adaptor with a mic... and find one! Only... it only pipes sound to the left ear! Indeed, all the adaptors I have tried, bring-your-own-headphones or otherwise, will only give me sound in the left ear. What the hell? I was in The Link today and the manager there said he had the same trouble with his Universal (only he has an official headset that works).
At first I thought maybe I'd damaged it somehow, and since there was some other stuff wrong with it I arranged for a replacement from Orange. No joy, this fresh unit behaves just the same. It really seems the only way to get stereo out of it is with a 3-core adaptor. Say it ain't so?
3 cores good:

4 cores bad:
I mean, are HTC wiring the 2.5mm jack differently to everybody else? Or did Orange mess up the case such that the 4-core plug doesn't sit quite in line?
I did get one off expansys, now that I think about it, that I think worked in both ears, but it had horrible speakers and was pretty uncomfortable. Besides, I took it apart to try and attach the plug to my old HPM-70, which sort of worked but, you guessed it, I couldn't get it to play sound in the right ear!
[edit] Whoops, wrong forum! I guess this belongs in accessories rather than upgrading. Perhaps a friendly mod could move it?

Hi Bobgorila,
I received a stereo headset with my TMO device & it works perfectly for all phine functions including adjusting the volume. Downside is the audio quality is horrible. So I switched to a mono BT earpiece for the phone & a decent stereo headphone with conversion jack for music.
Guess ther must be something wrong with your wiring.

My HTC Charmer gives me stereo sound with on `4 core` adapter, with mic, which I got from eBay, picture attached.
My unit came with a handfree headset, which is `4 core` and gives stereo sound as well, which is why I'm reluctant to get a `3 core` adapter.

Do you have a link for the one from Ebay?
had a look around but they don't look as "substantial"

Don't worry, found it
thanks

At the mall
My phone came with a 3 core stereo headset which I lost. I bought another 3 core sterio headset designed to work with the Palm Treo 650 which worked fine. I didn't need to hunt online, I just bought it at a cell phone accessory shop at my local mall. The Treo 650 is a very popular handset where I am in Canada and heasets are readily available.

I brought a ghetto 2.5-3.5 jack for $3.50 at a common hardware store.
Works with full sound on both channels on my O2 Mini, with a 3rd party 3.5" earphones that came from an el-cheapo Gemini Card Reader/MP3 player.
Looks rather oversized and gaudy, tho.
Remember that HTC sells only the spec and blueprints. OEMs are free to do whatever they want to the original design (called 'rebranding'). Orange may very well have rewired the thing....

headphone jack
I had problems with this. I noticed that on the 3-pole 2.5 to 3.5mm stereo adapter I got from Maplins the poles don't line up exactly with poles on my original headset. The HTC connector doesn't just have an extra pole for the microphone but each pole is a slightly different width. Using this adapter one channel was shorted unless I pulled the connector out slightly.
Sorry if that doesn't make sense, I will try and post a picture.
I did manage to find a source for 4-pole 2.5mm jack plugs in the UK, I bought a set of Koss earplugs and replace the original connector.

Just get a sonyericsson P900 stereo earpiece, it works wonder. sound quality is very good.

Bigger and better back speaker

Anyone have tried to change the default speaker with a better one?
Is it possible? And if yes how difficult?
The default one sounds like a fart from turtle ass, so that's why I'm asking.

I'm sure it's possible, but finding one that doesn't sound like crap would be difficult.

I also would like to know. It's a bit quiet. I sometimes miss calls when it's in my pocket.
Vibration is useless too

Let me see if I can find that teardown link. Maybe we can get a good picture of what it looks like.
EDIT: Here's the link.. http://tjworld.net/blog/htc-desire-z-tear-down

It looks like there is an easy access to that speker - after removing the rear cover:
http://tjworld.net/attachment/blog/htc-desire-z-tear-down/IMG_0235-small.jpg
It stays on the cover, not on the phone side.
However the speaker sits in the rounded plastic shell so replacing with a bigger one would mean playing with cutting it. Am I right?

You are correct, but it's nothing too hard.

So anyone would suggest a good speaker replacement?
It has to be something what fits in the amount of place there.
Maybe there are better solutions of the same size?
I'm compete amateur at this.
ps. and then how to mount it.

I seem to recall the galaxy s speakers being pretty nice.

"cell/mobile phone speakers" searching phrase doesn't work well for this matter. So I don't know how to find any such accessories on web.
Dissembling galaxy s for that wouldn't be cost effective, would it?

Hmm so the speaker is just too small - it'll have to be an extreme hack (i.e one which involves modifying the casing).
Any chance i could move the mainboard to Touch Pro 2 and keep the rest

Lol, That would be pretty sweet

So anyone knows where to buy phone speakers (the interior ones)?

After some googling, I found you this:
http://www.cellulardr.com/samsung-g...and-headset-jack-connector-samsung-i9000.html

Thanks.
The site is great!
However the link points to an earpiece speaker not a loud speaker parts.
I've made a search for loud speaker there. Now which one would you suggest for the replacement?
ps.
This one looks big:

However the one should meet some requirements, for ex. for current and the connection.

I'm still trying to find out more info on this.

Why not just use headphones? A lotta work involved here to just make the phones speaker a tad better. Not worth it IMO.

I think you have missed the point of this thread.

Exactly.
Think before you unintentionally start trolling.
Ive founf spare parts for nokia 5800 and what's written there is that there is ONE loud speaker not the two ones I thought nokia has.
However, if I'm wrong and there is ONE speaker that makes 5800 play so incredibly, it would be the nice direction to go to.

I have found where to buy nokia 5800 loud speaker.
http://www.mobilemonsters.lv/speaker-nokia-5800_p1028.html
There is some electronic info in the picture.
Anyone would help me understand it?
I can't find any electronic info about HTC loud speaker.
So please help me to compare the parameters of the two speakers. I mean especially voltage and resistance.
Will the Nokia 5800 speaker work on HTC Desire Z?

I used to build speakers and it will be difficult to get quality sound with such limited space. We can use a very expensive and tiny single driver. But even with high end drivers, a single one won't be able to cover a wide range of frequencies well, and there will be distortion at higher volume at certain frequencies. Or we can use a tiny cross-over and two tiny drivers (tweeter and woofer), or even three. I haven't looked at the disassembly, but I fear there isn't much room for more than single driver. Ultimately we will have to face some distortion, but this speaker is really awful so I'm open to it.
Unfortunately really small components like these are very expensive from audio parts stores. If you're not ripping apart another phone, the best bet would be these:
Bose IE2 ($100 at Best Buy) and you get two for that price.

A Soldering Adventure

So I recently accomplished the unbrickable mod for the SGS4G and I wanted to provide some info and a story so that you guys can see what it takes to do the mod, and get some laughs about how badly I almost messed up my phone.
Here is the link to Adam's post, in case you haven't seen it.
http://forum.xda-developers.com/showthread.php?t=1333424
At the outset, you should know that I attempted this mod with the help of my friend, who has some experience soldering surface mount components, and has a rather nice temperature-controlled soldering iron, solder paste, clips, a flux pen, magnifying glasses, tweezers, and a jeweler's loupe. My point is that we went into this with a pretty decent set of tools.
Step 1: Naïveté
After some careful thought, we attempted the mod and thought we had it. However, even with the loupe and other magnification equipment, we couldn't really see what was going on at these sizes. The phone booted, and I wasn't totally sure how the phone would behave unplugged. Plus we both had kinda run out of time for the day, so we called it tentatively good.
Step 2: Inspection
I happen to have a high megapixel camera with a macro lens, so later that day, I was able to get a suitable inspection picture and confirm that the mod did not take properly. It turns out that we had shorted the OM5 resistor, and this was causing the phone to operate normally, instead of being modded.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Step 3: Stupidity
Once I realized that the mod didn't take, I was disappointed and wanted to fix it. In my haste, I pulled out my RadioShack Cat No. 64-2067C soldering iron with the thought that I could maybe just touch the OM5 pad and get it to flow. Well, it turns out that cheap soldering irons are f-ing HOT and it immediately melted the adjacent resistor off its plastic(?) pad, which was now white. Oh, and the phone was now hard-bricked.
Step 4: Entropy
I called my friend for an emergency soldering operation. This time I brought my camera with me. We quickly cleaned off the solder. But now we had two effectively lifted resistors and decided we needed to come up with a recovery strategy. Based on looking at the pictures, we came up with a notional schematic. Unfortunately, in the process of probing with a multimeter to try to determine some resistance values, another resistor popped off. Well, damnit. We measured this resistor at 100k-ohms. So these look like protective resistors for what is probably a high-impedance input.
Step 5: Cleanup
We realized that the OM5 bridge was still there. This was based on a resistance measurement and you can see a bead of solder in the picture above which looks like it was still making a connection. We went in to try to get this solder to flow.
Step 6: Square One. Or Negative 2.
Things are getting bad. Two missing resistors, and our eyes are getting tired. Spouses are getting antsy. We decide the best way to move forward is to try to get a small bead of solder onto the tip of the iron, and try to create bridges where the resistors were. The first one was a success:
Step 7: Are You Kidding.
Well, with that rather clean-looking success, despite the fact that what happened above was largely due to good luck, we decided to keep going with this approach. We couldn't think of anything else to do... Unfortunately, we didn't know how to get a small enough blob of solder onto the gun, and the next blob was a little too big:
Step 8: Square Negative 3
What is immediately clear in the above picture is that we are completely screwed. Another resistor has lifted, and there is a sea of solder shorting the remaining resistors, and if you look closely, you can see two of the resistors floating together in the solder tsunami.
Step 9: Patience
We cleaned this up, and with some luck, were able to reestablish one of the connections. We still felt kind of lucky about that, and decided we needed to try another approach if we were going to proceed.
Here is an attempt at solder paste. Which basically was too messy to difficult to apply at this scale:
Also, notice the beads of solder in the solder paste. This is not normally what solder paste looks like to the naked eye.
Step 10: Slow Progress
We figured out we could reflow already-melted solder that was hanging around the station on some paper, and with some mushing and chopping motions with the iron tip on the paper, we could subdivide the solder into smaller and smaller quantities until we had a very tiny sliver floating on the end of the iron. We started doing this:
Step 11: Victory
Repeating this process with the solder beads bit by bit, we carefully added solder until we had the configuration we wanted. This was tricky, because surface tension wanted to keep the solder of the solder-resist. Also heat conduction would sometimes cause adjacent solder to flow when we didn't want to. First, we had this:
Yes, a mess. But we had determined through our schematic analysis that the left four resistors were originally grounded, so as long as we preserved a connection on the top middle resistor (above OM5) and prevented a solder bridge forming on OM5 itself, we were good to go. Now to work on the high pins:
Close....
Got it. This may look like a hot mess. And it is. However, notice that there is electrical separation between the logic level low inputs (connected by the upside-down L shaped glob on the left) and the logic level high inputs (connected by a glob which looks like maybe and Android robot doing a situp).
We booted the phone, and we had it. Successful mod.
Step 12: Denouement / Lessons Learned
To perform this mod successfully, you need to have access to good equipment. Visual inspection at these sizes is going to be difficult, especially if you start to get discoloration and other things making the image confusing to your brain.
Performing this modification requires a pretty high level of soldering expertise. These resistors are not much wider than a strand of copper speaker wire.
Have a way to verify your work. Like a camera, USB microscope, or some other way to get a good look at what you've done. Even with the loupe, this stuff was hard to see.
Be patient. Be aware of what surface tension is going to do, and what effect using flux will have. Practice on something if you have it.
If you are getting tired or fatigued, walk away for a minute and come back to it.
If you find yourself in crisis, think through the problem so you know how to define success.
Adam's guide in this forum is rather brief. However, he has references at the bottom that lead to quite a bit more information about what he has done. This information is valuable and can help you understand what is going on. I would review these references at least a little bit before you get started on this mod.
You can solder anything.

Here is a picture to help with scale:

Wow the scale made it look a lot harder.

Quite the adventure bro! I use a Hakko soldering station (var. temps). Works wonders. A little desoldering wire and flux are key. Glad you got it going! I've done the same thing in the past lol Literally a hot mess My only concern would be the 2 missing resistors. Good work. Thanks for the post!

Yeah, my friend had a variable temp soldering iron too. We did a lot of the work at lower temps than usual in the hopes that the solder would be "stickier."
I was a little worried about the reistors too, and it may shorten battery life a bit, but there are probably resistors on the inside of the chip and they are likely high impedance (inputs usually are), so I doubt I will see a difference. On something like an ARM i would guess they would be rather high--i'm going to go ahead and guess 1M-ohm. I should look it up. Noise immunity should not be too much of an issue for configuration pins, and, well if a short develops inside the chip I suppose it could cause more damage than might normally happen but honestly if that were to happen the phone would probably be toast.

[Review]MPOW Armor Plus Bluetooth Speaker *Many Pics inside*

Hello,
I got this nice Bluetooth Speaker from <MODERATOR EDITED - SPAM LINK REMOVED> for an honest and unbiased review. I was excited to try this item since I like rugged type of gear
<MODERATOR EDITED - SPAM LINK REMOVED>
From the looks of it, these Speakers look like some sort of military type of equipment.
The whole device feels pretty heavy and solid which is a good sign. The case is rugged and uses iron frames, metal speaker meshes and is stabilized by a strong TPU rubber. The case structure is very tough and also water resistant which makes it great for outdoors usage while eg. having a nice BBQ.
I´m confident that this device might survive some severe drops but I won´t perform any torture tests like these
The build quality is excellent, the packaging itself also makes you feel that you´ve obtained a high grade item and not something cheap.
This item might survive one drop out of a plane without a parachute because of how good it´s protected inside the box
Accessories:
1x USB Cord (USB Type A - Micro-USB-B)
1x Audio Cable (3,5mm - 3,5mm Stereo coaxial)
1x User Manual
1x Nylon Bag
1x Nylon Rope
In order to charge this device you need a additional USB charger which is not included. Just use a USB charger which can deliver about 5W (5V @ 1A) and you´re good to go. I guess that most guys here have spare chargers they can use

}
Tests:
This device is very intuitive to use and the user manual is easy to read too.
I charged this device with my DIY power supply and measured a current of exactly 1A. If you charge the device and also play some music, the current might rise up to about 1.1A.
What I like about these speakers is the fact that you can also use them with a wired connection through a standard 3.5mm Stereo cable.
You can simply connect them with any headphone jack of every device. These Speakers can also be great companions for your Notebook and replace the tiny built in Speakers
The Bluetooth Connection is stable, even if you move away a few meters from the speakers with your phones. I´ve tried a connection with my Nexus 5 (2013) and Nexus 6P and didn´t have any problems.
You can use your phone or these Speakers in order to swipe through music tracks or answer calls.
What´s also nice to have is the possibility to share the integrated 5200mAh Battery Cells which feed the Bluetooth Speaker in order to charge your mobile devices if you´re out of juice. This could come in handy in emergency situations if you don´t have any extra Power Bank with you.
You would be able to charge devices at a current of max. 2A which sounds great.
Assuming that the charging circuit used in this device works at a efficiency level of around 88%, you might expect a usable capacity of about 3386mAh which could be used to charge your devices
You have to keep in mind that this is just a close approximation and only works out if you use all the juice for charging only.
Did I forget anything? The Nylon Bag and the Nylon Rope included with these Speakers also help you to transport this device without scuffing the nice case
Sound Quality:
Now comes the tough question, does this item also sound great? These Speakers are quite small in comparison to some active PC Speakers but they deliver quite a unexpected punch.
To be honest, you have to compare these Speakers with similar gear in order to rate their performance. Don´t compare them with your 1000W Hifi Stereo System which would win by far but also costs a lot more and cannot be carried around in your backpack
The lows are very strong, the mids are well balanced and the highs are soft. Even if you crank up the max volume, you won´t hear any distortions. These Speakers are very loud which is really impressive.
The tonal quality isn´t dull and not very bright sounding either. It reminds me somehow of older Hifi equipment from the 80´s which also sounds a bit stronger in the lows frequency range and offers softer mids and highs. I think that the results are very well balanced.
I´ve tried these Speakers with various types of music and it´s really a pleasure to listen to them. This is nice since I intend to use them outdoors and can hardly await the summer to come
When it comes to preferences, all people are different. I can´t guarantee that you might also like the sound quality as well as I do, this is why I can only tell my own impressions.
In conclusion, <MODERATOR EDITED - SPAM LINK REMOVED> has designed some serious Bluetooth Speakers which deliver some unexpected performance and tonal punch as well.
I hope that I could help some of you to have a closer look at these Bluetooth Speakers if you´re looking for some rugged companions for your phones as well

Magnetic micro usb adapter /cable

I read that the usb port of Mi max is very easy to scratch, is using magnetic micro usb adapter or cable a good solution?
Sent from my SM-T715 using XDA-Developers mobile app

So you'd rather have something stick out than some scratches only visible if you specifically look for them? I wouldn't even noticed them if didn't read this few days back.
I really don't get it...
It's just a phone, tool ment for every day use.

I agree. Anybody who knows me personally will tell you that I am anally retentive when it comes to the condition of my gadgets. Seeing someone use a phone with a cracked screen induces almost Jack the Ripper levels of rage in me but this isn't a huge problem. I have had this phone for around 5 days now and can see some very very small scuffs on the bottom of the charging port but only when I hold the phone very close to my eyes and specifically look for them.
It might also help that I haven't used the cable that came with it. At work I charge the phone using an old Blackberry cable and at home I've either used the cable from my PS4 controller or a high-speed fabric threaded one that I picked up on a market in Hong Kong last year. None of those cables have small studs on the micro-USB plug that I have seen on some other cables over the last few years. I have no idea what the included cable is like as it is still in the box untouched.

I wouldn't be happy if something that affects functionality shows up over time too.
Actually Mi Max USB port is very well protected from getting loose over time with that tight frame opening and that's why it gets some minor scuffs. I'd rather have that than loose port with weak electrical contacts. That's exactly what I had with my previous $850 Samsung Note3 in less than 6 months of use. Mi max won't develop this because USB cable connector is supported by the frame, not the port only...

micro USB
I believe that the micro USB - is a big mistake. Its construction took not engineers, and a herd of old. Built on a design twist on the wrong side. Back Lighting. Look into the micro USB - you see an unfortunate engineering decision. It's like Apple revenge, and we are paying the price. 5 contacts arranged on a plastic plate of 0.5 mm thick. Which hangs in the air. After 2 years of daily use, this plastic (probably made from waste and old bottles) turns into a rag. I have a phone with a cable fell onto the pillow !!! Now the connector loose. This occurs when the decisions are made by intriguers, not engineers, but the entire planet obeyed. Where were the engineers at the factories, and even in China? Are you afraid to say too much words and held on to his salary?
Based on the foregoing, Type-C with 24 contacts - even sillier.
Whiter than a weak structure, not protected from the slightest mechanical impact, it is difficult to come up with.
Perhaps a little magnetic cable will extend the life of my micro USB connector, although the charging current is reduced by approximately 25%.
In the USSR before the shot for wrecking the economy. In some ways, my grandfathers were right.
