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...
Alternate title: Why does my new eReader not make a great audio player too?
So, I went out and bought a Nook Color on Friday. I bought it for the Android hacking fun and doubt that I'll ever use it for its B&N "intended purpose". With that being said, I've noted that there is a hiss / static in the headphones any time the audio is enabled. There appears to be some self-muting going on on the device itself almost as if it is completely disabling the bias to the audio output transistors after some seconds wherein the hiss goes away but, any time there is active sound going on, the hiss and associated noise (likely RFI getting into poorly designed/shielded audio circuitry) is very clearly and annoyingly there.
I'm using very good headphones (Bose QC-3's) which sound wonderful on everything else I plug them into including my Droid and Milestone phones.
Has anyone else noted this very annoying audio issue on the NC? If I don't figure out some way to get rid of it, it's going to put a serious damper on using the NC to watch videos when I fly. (LONG trans-oceanic flights!)
I noticed a slight static noise from the built in speaker on my NC. I've not listened that much with headphones - and it was in a noisy environment.

Usually portable audio front ends include a mute circuit to suppress the pop when the power for the amp turns on and off to save power. But that's besides the point...
My ATH-M50s give a lot of hiss when plugged into the NC, and at 38 ohms are somewhat less sensitive than most cheapie headphones that these amps are usually designed to. When I get a chance I'll try some higher impedance phones.

Might be worth taking your headphones into a B&N store and trying another NC out to confirm its not just an issue with your unit.
Have the same issue with the NC and bose QC3 head phones. Plugged in a cheap pair of ear buds from the airlines and no hiss.
The amp is definitely noisy-- the worst I've heard since my 1st Gen iPhone. I guess they had to skimp somewhere.
Yes, pretty hissy sound. I can live with it, I think, but it's bit disappointing.
Ditto. The hiss using my Ultimate Ears makes the Nook Color unusable for audio or video in a quiet or normal environment.
It might work on a plane where the ambient noise is so high.
Pretty loud hissing sound with both apple earbuds and image s4's.
I noticed this too the first time I used Pandora...
Typically, for me and I assume it's the same for most pepole...
A reader likes to read in a quiet environment and therefore when they do decided they want to use the audio on their nook it is for music at a lower volume in a quiet setting. So this static / auto shutoff problem is blaringly obvious.
Any chance this will/could be fixed with an update?
If not then the audio feature will be useless for me
*edit*
Also... the static only gets worse (louder) as you up the volume. So listening to the music at a higher volume doesnt mask the static it only makes it worse
I have the same noisy audio. I am very serious about my audio equipment, but I don't put the NC in that category. Yeah, it would be nice if it sounded great, but the hiss would not bother me for video & I prefer to listen to a quality MP3 player if I listen to music. I would actually rather make adjustments to a dedicated player, while reading, than use my ereader to change screens & make adjustments. The other factor is the impact on the battery life. I guess maybe not a big deal on the NC?, but surely with an eInk reader. I hope you can find a way to live happily with yours.
Cheers,
kev
Ditto for me too. Hiss makes Pandora unusable when using my ultimate ears. I'm definitely disappointed, and a little less eager for flash support now.

I have no problems at all with audio on my nc. In fact i haven't had any of the problems i've heard on the forums as yet. Hope i never do

I think there might just be inconsistency in the NCs, neither mine nor my brothers have this audio hissing problem, or the problems with the bezel/frame, or any of the other problems the have come up on the forums. Maybe they are being built at multiple factories and some just suck? or maybe they just don't do any quality control? Who knows, I would check out the NCs with other headphones (although it sounds like you use these headphones all the time, so it's unlikely that they are the problem) and your headphones with other NCs.
OMG... the nook color sucks at playing music when using the Panasonic RP-HC700 Noise Cancelling headphones. The static is almost unbearable. I posted a recording of it on youtube under the user name MilkManMOM. (I can't post links and be helpful yet) Grrrr...I'm angry now at B&N.
No audio hiss from headphones on mine. If yours does, it's defective. It's also still under warranty. Stop just complaining to us about it and have B&N fix it.

Try a different set of headphones. My Bose IE2s are fine, but my Senhiessers have a lot of hiss, especially when I use an inline amp.
My quick test leads me to belive that earbuds meant for mp3 players work fine, but head phones have issues. This might be an impedence issue.

Its either a Impedance issue or Frequency issue. When using my good Sony Headphones which are Frequency Response : 5-24,000Hz I get a Ton of Hiss, but when I'm using my Crappy Work Speakers which are Dell 215, which has a Frequency Response of 100 - 20000 Hz I get No hiss at all.
I have not tried the Official Nook head phones but they are Frequency response: 20 Hz-18,000 Hz
My guess is that our Head phones are just too good for the Nook and we are hearing the Hiss in the Higher Frequency Range that "Normal" Headphones often can't reproduce. I have had the same issue with cheaper MP3 players you end up hearing the electronics in the device working. Good MP3 players and other media device normally have this sound filtered out or have things shielded in such a way that it minimized the effect.

Ummm, no. First, anything above 20kHz is inaudible. Second, if you do have extraordinarily rare "miracle ears" and can hear slightly above the normal range, nothing above 20kHz would sound like a hiss... it would be an incredibly high-pitched whistle. Try playing around with a tone generator and see for yourself what extreme high-frequency sounds are like.
Oh, and I assure you that your Sony headphones cannot produce 5Hz and 24kHz tones, no matter what their marketing department claims.
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.
Sent from my HTC One using Tapatalk 2
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.
This problem has been reported on the Samsung Galaxy Note, S II, Droid DNA and others, but I didn't know it was also a problem on the HTC First until I got mine. Whenever my music goes to a low volume with my headphones on, the sound just mutes. It comes back when the music goes louder. If I increase my volume, it cuts off less. At full volume, it does not cut out at all. I have no problems playing through the speakers.
One needs to listen to audio with short silences to be able to notice it. Some say it is related to Beats Audio, with the problem going away if Beats Audio is turned off; I don't think that is a possibility on the HTC First, though.
I use my phone mostly to listen to music and streaming radio, so this is a deal breaker for me. Are any of you experiencing the same problem?
i can not confirm the problem.
i tested my HTC with BOSE and Pioneer headphones and do not have any problems with both.
no matter if i play music loud or very low volume.
will test it tomorrow with my monster beats and let u know.
HTC Support on Sound Cut-Off Issue
For the sake of completeness, I will let you know that I called HTC Support about this sound cut-off issue. The person on the phone was very nice and tried to help me for some 40 minutes.
The bottom line is that he couldn't reproduce the issue in the few songs he played (which didn't surprise me). He made some note for the developers but I don't think anything will come out of it.
In the meantime, I found a good song to test this strange behavior: "brainstew" by Green Day. Plug your headphones to your HTC First and listen to the first 30 seconds at low volume. It you hear distortion as the sound volume changes, please let me know (right now it seems that I'm the only one noticing this).
Thanks!
I'm seeing this as well. Has nobody else seen this?

I'm not sure if this is normal or if the speakers of my HTC One are defective. Whenever I use the speaker, I can hear slight hiss or background static noise. By slight, I mean I have to put my ears like 10cm next to the speakers to hear it. I don't hear the static when I'm using the earpiece for calling.

I had slight static from my speakers straight out of the box, different nofications and ring tones seem to do I just put it down to quality of them when streaming videos or music don't seem to have the issue. I find its all good as long as you don't have the volume up full.
Sent from my HTC One using xda app-developers app
For me the static noise appears when I'm using youtube, poweramp and speaker phone during a call. Like I said, it's only audible when I'm in a quiet place using low volume. Just want to make sure those speakers are not damaged or something
