Background noise when using headphones

I bought a pair of Sennheiser CX300 headphones for my HD2 and I started noticing an annoying background noise in every audio application (including games). The noise volume is constant so if the audio is below a certain level it starts becoming very noticeable. It is also strange that the noise continues for about a second even after stopping the audio. I tested the headphones with other devices and they work fine.
I wonder if anyone else has this problem with other headphones? Does this have anything to do with the impedance of the headphones (16 Ohm for the CX300)?

Hi, I also baught in-ear-headphones the day before yesterday, stood infront of the sennheiser ones you baught but took the Sony MDR-EX76LP instead.
When I tested them I didn't hear a background noise but was not really impressed by the sound.
I was used the in-ear headphones that came as headset of my Sony Ericsson W800i cellphone and they sound much better and also isolate the outer noise (much better in airplanes and so on). Also others can't hear what I'm listening to which is also nicer in the metro... Seems to be a feature for the new Sony headsets but is rather a bug for me...
So I build myself a new headset using the HTC headset with remote and mic and soldering the old sony ericsson in-ear headphones onto the remote. Works really nice... I also took pictures to write a HowTo and will upload them maybe later... Similar description...

[Q] Fluctuating Sound Problem?

Hello,
I bought my One on Tuesday and it's been great so far, but today I've noticed that playing it on the top 3 volume levels causes the sound to kind of fluctuate, as in, some parts of the song play louder than other parts.
This is less prevalent with beats audio turned off, however I believe I can still slightly hear it.
It's most noticeable when I plug it into my car's aux port and turn the volume on the phone up to its max.
Has anyone else had this problem? is it a software issue? or will I have to take this phone back?
Thanks

the phone have 2 speaker one in top on in bottom.
2.1 speaker working in phone perhaps the song getting change between to speakers and you think that happened.

Sorry if I wasn't clear, the problem only happens with headphones plugged in

[Q] Hissing noise in headphones?

Hey guys,
I've been using an HTC One for two weeks now, and was really looking forward to using it as a music-listening device. However, whenever I'm listening to music on a low volume setting through headphones I can hear a hissing sound that gets louder and softer as the music changes. Since then, I have tested this with another HTC One, various headphones, and have come to the conclusion that something inside the phone is causing noise. As soon as I open up the 'Music' app or any application that turns on the headphone jack, I can hear the hissing. It's very noticeable when listening to music at night in the lower volume settings. The same files I'm listening to have no noise on my blackberry or on my iPod.
Any thoughts?
Thanks.

I can only suggest you exchange for another unit. Yup... I saw that you said you had tried another One.
I came from Nexus 4. My first Nexus 4 had a defective earpiece and the same hissing noise you described from the headphone jack. Did a RMA with Google, and the second Nexus 4 had a perfect earpiece but still some hissing noise from the headphone jack. I didn't want to bother with the RMA process again so I just lived with it.
Then I got my HTC One. Sound quality is miles better than the Nexus 4 and I hear no hissing noise from the headphone jack.
While the chance is slim, it is possible to get defective unit twice in a row. The hissing noise is probably due to in proper shielding or poor wiring inside the phone.

Hi,
Try turning off beats audio and see if it still happens.

I would agree with gustav30. I have noticed this recently, but it only happens when I am toggling the beats audio on and off. I think it might have something to do with the different audio qualities depending on what type of thing you are doing i.e. streaming music, listening to downloaded music, watching YouTube, etc..

Its beats audio. Turn it off and the hissing decreases. You will always have some hissing though no matter what phone and headphones you have.

Beats lowers this hiss, but its still there.
This hiss exists for all android devices I've used and heard when using high sensitivity IEMs.
Considering going back to apple... *sigh*

Has anyone here experienced prominent crackling sound listening to music at full volume when using HTC headphones supplied with the phone ?
I tried using the same headphones on One X but no crackling sound or even on the computer.
It does dis for all the songs I play at full volume on HTC ONE. (it does reduce the crackling noise if I turn off the beats audio).
So wut do u think cud be the problem ?
The headphones, the phones hardware or the beats audio.

[Q] My headphones are scratchy on my One, any way to fix?

Hi,
I've got beautiful Sennheiser Momentum's here and I've got a problem. They make scratchy noises in higher pitches, say slow or silent songs with high voices. This happens with Beats off at the last two volume settings and with Beats On even before that. The same mp3 does not sound scratchy when I play it over my PC with the same headphones plugged in. It's defnitely the phone because the In ears that came with the phone sound equally scratchy at exact the same volumes.
Is there any way to equalize the standard audio settings without having to use another audio player? I am running ARHD 31.6 and tried it with and without PureXAudio, doesn't change anything.

I reset my phone now to make sure the XAudio-stuff isnt flying around, but the problem remains. But I think I found the culprit, the particular song where you can hear it really good simply seems to be too low on volume in the file itself - i can barely endure other songs at that volume, very loud, so I think the song has a low db and the htc just isn't that good when it comes to making songs loud and so it starts to scratch. Is there any way or EQ that can fix that or a normalizer?

I have noticed that my phones speaker was louder and better clarity on first use but after that it went downhill from there. My phone is currently in for repair due to a total speaker failure after the phone got really hot while using a CM 10.2 ROM, do not know if that was the reason but that was the ROM I was using at the time.

Well my best guess is that the built in EQ isn't the best out there and causes screeching in some frequencies. I can't notice anything in most of the songs but there are some which are problematic constantly and they are 320kbps and sound fine on my pc.

Hissing when playing audio through headphones.

There's a hissing/static noise whenever audio starts. If I pause it'll stop after a few seconds. Anyone know the cause of this?

I'm also interested in this. When I tried playing in my car, firstly I thought it could be software or some equalization problem. But, even deactivating all, that hiss continued so maybe it could be the quality of audio cable (quite poor).
Trying at home with a quite decent pair of earphones: Sennheiser IE8, I still can hear the hiss. It is much less hearable (suppose less amplification of sound, I've been listening music at maximum level to detect it), but also here.
I think there are only 2 possibilities: bad software/ROM implementation or defective/bad hardware. The defective hardware is rare, I've read some opinions and all say more or less the same... I expected some more quality of sound, and more if it comes from Sony...
