Hey guys,
I bought a One X recently, and I am noticing some static/hiss/noise coming from the headphones.
I tried connecting my One X to bigger speakers, and the noise is more noticeable this way. This is an odd issue, because none of my other phones behave this way.
The funny thing is, if you play music or notification noises play when the phone is connected to speakers, the noise goes away. But after one second, when the DAC shuts off, the noise comes back again.
My friend's One X has this problem as well, so I don't think I just have a lemon here.
Other forums seem to be talking about this issue as well

I found one review that mentions this issue. They talk about it in the Beats Audio section, and there's a video with the noise.

I remember using a really cheap chinese knockoff mp3 player about 8 years ago, and the One X seems to have the same problem as that mp3 player. Could it be that the One X has a cheap DAC in it that causes this noise?
Anyone else experience this problem?
The first link is about the international version, the lte one x is technically the One XL, and this is the first time hearing about this. Mine doesn't have a problem and I listen to music all the time.
Just and idea possibly cheap headphones?

My music is crystal clear, probably one of the best quality sound outputs I've heard from a phone actually.
Mine has this problem, but I only notice when I hook it up to my car speakers (with an aux cable) and not with headphones (Bose). It's a lot more pronounced when the phone is plugged into usb as well. Once sound plays though, the hissing stops completely. It's only when there is no output that the hiss is present.
Edit: Could it possibly be interference from the cellular radio? Maybe once the DAC kicks in it filters out the interference?
Edit 2: Just read the 3rd link and yeah, my speculation seems to have some validity
"Adding insult to injury, HTC One X features a badly shielded headset jack that makes noise whenever it is hooked up to sensitive speakers. We compared it to high-end and low-end phones, and none of them made the annoying static noise that the One X makes. This isn't a serious problem for people who only listen to music through headphones, but you may want to stay away from the One X if you are thinking about playing music through it with big speakers."
I had the same problem. If you are rooted, disable beats audio notify with titanium backup. I did this and use power amp with custom eq settings and do not notice any hiss whatsoever.

Same problem here. WAY worse when plugged in and in my car. On regular headphones no problem. In my car it's huge. To me it reeked of a poor ground somewhere, to the point that I thought my unit was defective. If it were a shielding problem I would think it would be an issue all of the time, not just when the thing is "inactive" (ie not driving the jack). I've "disabled" beats to the extent that I can without rooting, and it had no noticeable difference.
Glad to hear it's not just me.
I notice the problem when I use both the microUSB charger and headphone jacket. Disconnect the charger cable usually solves my problem. Now, I switched to use BT car adapter instead of aux cable and I can use car charger without noise.
The problem is called BEATS AUDIO!

I still get the hiss despite disabling Beats (as in just turning it off in the notification shade), although it is definitely not as bad as having Beats turned on. I'll freeze HTCBeatsNotify and see if it helps on the way to work tomorrow morning.

Sadly beats audio is integrated beyond what you can turn off in settings.
so, the only solution is to root the phone and completely kill Beats Audio?
I guess it's not a hardware problem then... Man, that sucks. Has this issue been brought to light by some big sites yet? We need to do something so HTC learns from this mistake.
By the way, here's the update I promised...
Like I said before, I disabled beats from the notification pulldown but the hiss was still there, although slightly less annoying. I froze HTCBeatsNotify (or whatever the actual name is) using TiBu so Beats doesn't even show up when I plug it in. Unfortunately, the hiss is still there at the same level it was at when I just disabled Beats from the notification pulldown.
Is Beats actually integrated into the hardware? Is the "poorly shielded headphone jack" mentioned in one of the OP's links still a valid assumption? Can someone running CM9/AOKP chime in on whether they get the hiss?
Edit: Before I head home today I'll go into Airplane mode to try to rule out the headset jack shielding.
Annnnd of course my experiment failed...hiss is still there
If the headphone jack is indeed poorly shielded, couldn't it pick up interference from anything? Not just the internal radios?
This means we'll have to go into some radio-free environment in order to determine whether it's the headphone jack or Beats Audio that causes this annoying hiss.
In either case, I'm disappointed in HTC.

Well I mean, the internal radio would be the strongest signal in the immediate area that would cause interference. Just look at old, poorly shielded computer speakers, they had issues only when a phone would go off within maybe a yard of them. I was in a parking garage at the time I tested and I'm not sure if there was anything else around that would be powerful enough to cause the interference.
Also something I noticed which may lend credence to the DAC being the source of the issue...Just plugging my phone into usb and having the headphone jack attached does not produce as much interference as when I'm streaming from Google Music and it gets caught buffering. As in, when the DAC would still be active but no audio is output. The hiss during that situation is quite a bit worse than just having the phone sit there not doing anything.
Since Beats is just a glorified equalizer, it could be that Beats just happens to be boosting the sound frequencies of the hiss and making it sound louder, and not the actual source of the hiss itself. So maybe it is a hardware issue.
Again, I can't imagine ti being "poor shielding" because that would not immediately go away once you started playing music. Think about typical cell phone interference from a radio. You're playing music, and you hear that "bvvvvrerrerrr" sound.
In the case of the HTC, as soon as you start playing music, the hum goes away IMMEDIATELY and completely as far as I can tell. If shielding were the problem it wouldn't it still be distorted regardless of whether the jack was actively playing anything or not?
Seems more to me that the DAC is leaving some signals floating, leaving them susceptible to noise, when it's not active, when it should be pulling them to a known state (probably ground)
Not from DAC either. If you plug in a headphone, you will not hear these noises. It seems only occur when you plug into AUX import of car or amps.
So, it is a hardware design problem that causes dirty interference escaped into audio output. When you plug in a normal headphone, it has very low impendence and the noise will not get amplifed at all. If you plug it into an AUX import, it will have a much higher impendence and hence the noise get carrier over and amplified.

Your explanation makes perfect sense. This seems to be the issue.

hey guys,
my One S has buzzing noise coming from the headphone jack, and this problem is pretty annoying especially when it's connected to my car stereo. I thought it might be just mine, but it seems like this is a common issue.
i found this video on youtube. I have the exact same buzz from my One S, though perhaps not as accentuated as in this video.
seems like the One X has this problem as well. found this thread at the One X board http://forum.xda-developers.com/showthread.php?t=1720212
is this a grounding problem in the headphone jack? Beats Audio? what do you guys think?
I've always had this problem with more than one phone. If you charge the phone via USB adapter from the car battery, it gets 10x worse.
This problem only happens when sound is being played back, so when music/video/game sound kick in, it stops. Do you get that noise when sound is being played back?

The buzz is only audible when nothing is playing. Like in that video, when I stop playing music it will be silent for about 2 seconds and then the buzz kicks in again.
I didn't have this issue with other phones
I don't have any buzz, I double checked just to make sure.
Although it might be my headphones, the output is probably not strong enough to play the sound.
It's probably being heard in your car (or in the youtube video) because the output is being amplified.
I'm having the same issue with YouTube and Pandora.

you're right. the issue isn't as noticeable through earbuds. i think that's why many people are saying they don't have this issue. It's still bad though.
I don't know why HTC messed up this part when no other phones seem to have this issue. Makes me sad.
If it's easy to reproduce for you guys, I'd definitely be pushing for warranty replacement.
I do not have this problem at all. On my cheap pair of headphones or on my expensive one. No hum or sound.
the buzz is there, and it also was on my Desire.
Not when playing tho, only when connected and not playing. Not too annoying, always thought it was supposed to be like that.
And no, I have never heard it through ear buds or phones, only when connected to home stereo or car stereo, and if charged through cig-lighter-outlet it amplifies further...

It doesnt effect headphones, only when the sound is amplified. Like when you play music in your car.
Simply because that sound alone is not enough to drive the headphones.

Whether its plugged in to a car or home stereo, its still using the output from the headphone jack. The power output from the jack is the same either way.
I plug mine in to the aux jack of my car stereo daily, and I have no buzz or hum. Do you have your phone plugged in to a power source at the same time? That buzz is usually caused by crosstalk from a poor quality power source.
Or, as I said earlier, it may just be a bad phone.

Well my phone doesnt do it in my headphones. I can't test in car, no aux input.
What I was saying is that, of its buzzing in your car but not on your headphones its because the sound level at which the buzz is at isn't enough to drive your ear buds. But when the car stereo amplifies it its easily driving your car speakers.

Hi All,
I have recently come back to the OP7P after using an XS Max. I have been using Airpods 2 with the iPhone and the volume on Bluetooth was superb. Most the time I listened with it a few steps from maximum.
Now with the Oneplus I'm currently using the Cambridge Audio Manomania as they had really good reviews but the volume is no where near. I've tried changing the absolute volume setting, flashed the booster in magisk and tried using AVCRP 1.6 but it's still really low.
Does anyone know any Bluetooth buds or USB c headphones that will at least deliver similar volume to the Airpods?
I recently purchased these Treblab earbuds and I am happy with them. They don't sound as deep as my Phaiser headphones but when the volume is raised on the Treblabs it's pretty crisp sounding and volume is pretty high. I want to add that I have never used the apple airpods though. I just downloaded one of the viper audio mods and I'm going to see how that interacts with the Treblabs.
Over all I'm loving them though..pretty loud and my work environment is noisy

I've Xs Max too & I'm using First Gen Airpods with 7 Pro & They get pretty loud , equivalent to iPhone. Only Thing I noticed is that maybe battery drains faster. I'm not rooted, everything is stock
Maybe I'll have to try airpods again just wasn't sure how well they would work.
Was thinking of powerbeats Pro as well but no way of testing them before hand
I got Amiron Wireless of Beyerdynamic and I am fine with them.
