Car Chargers / Headphones - Nexus 4 General

Hey Guys,
Mentioned this on a couple of other threads, but I feel it needs a dedicated one.
Firstly, the output from the headphone jack to the line in on my car is poor, the level is so low i'm cranking it up to 20 just to get a decent listenable volume level, my previous phones (Atrix, Nokia N900) didn't require this.
Secondly, if I use my car charger with the phone and try and use the line in, there is massive interference that is louder than the output its self making it impossible to listen to music. Again another issue not present on my previous phones using the same charger.
I am going to attempt to make a recording of the noise, and I'll upload this later.
Can a few other people test this out and see if you get the same result please?
Cheers
Andy

Just get a ground loop filter for $5 and you are golden.

I have noticed low headphone output also. I use a ground loop filter so I haven't noticed too much white noise but having to turn up the volume louder than normal to make up for the low output makes it worse. I only hear it in-between songs.

Hmm I'll try and find a ground loop isolator and see if that makes any improvement.
Just don't understand why it is such an issue on the Nexus 4.
The noise for me is louder than the audio that is being output rendering it useless. Going to upgrade my car with bluetooth at some point so that will solve all the problems.

[Q] Hiss / Static in headphones on Nook Color

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 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.

[Q] Whats up with the headphone jack?

So I have looked everywhere and havent really found the answer im looking for. First of all my headphones, also others i have tried including an aux cable dont seem to fit into the nook color headphone jack all the way. This is causing problems hearing sound in both ears, or getting any sound at all. I have to fidget to get it just right. Does anyone have any solution or similar problems? A specific pair that work?

It isn't broken. Just stick the headphone jack in and when it gets stuck just push on it until it goes in

i found mine to be a bit hard to plug in and unplug but im kind of use to it now, i just thought all nooks were like that
It requires a bit more force to insert and remove than other devices I have, but that also makes them harder to disconnect by accident. /shrug
They do work fine if you insert them all the way rather than stopping at the first click, as the tip slides past the ring contact, which may be what the OP is doing.

lol no problem it was a valid question and i was wondering the same thing when i first got my nook color, i just accidentally ran into the solution like 1 hour later lol
Yes, the headphone jack is extremely tight on the NC. I feel like I am going to break something every time I am plugging in the headphones. I am sure that they inserted completely. However, out of 5 "plug in and out" cycles, only 1 will yield the full spectrum of the frequencies for me. Specifically, there is no bass, all mids and highs. I have to plug and unplug few times to get sound with bass+the rest. I am not complaining that the bass is weak, there is simply no bass at all until you get a right "fit". I tried 5 different headphones (ranging from cheap iPod headphones to UE TripleFi 10) and different sources (e.g., Pandora, music player, etc), and the result was always the same.
Anybody else with this problem (i.e., complete lack of bass until you find the right "fit")?
3.5mm TRS audio jacks have three contacts, one each for the Right and Left stereo channels and one for ground. A channel is either present or absent. Any bass issues you are experiencing are not due to the jack; it simply is not wired that way.

I am certainly experiencing this issue as well. I've found a way to reproduce it. If you push the plug in fast enough all the way, you can get the plug to produce full sound, but if you push it half way in and wait for NC to change the sound from speakers to headphones you'll be missing some spectrum, after you're hearing broken sound coming out of your headphones, even if you completely push in the rest of the jack, the final results will be missing some spectrum. So the only way to get complete sound is to push the plug in before the NC switches to the headphone output.
Wonder what a pair of the little powered external speakers would sound like?

[Q] Increase Soung Output Through Head Phone Jack? Stock Rooted

I am loving my Nook Color. Using it to replace a laptop and books I take with me on plane trips for movies and reading.
I am running 1.1 Stock and Auto Nootered. I have my file re-encoded for playing on the Nook and they look great. Problem is with sound all the way up and using my noise canceling headphones, the sound is not quite as loud as I would like.
Is there a way to increase the sound output to the head phone jack?

See this is an entirely different science.
Often, both noise canceling headphones and high quality headphones require a certain about of ohm's to power them. Many people even use headphone amplifiers to amplifier the amount of ohms the headphones recieve, which in turn boosts the volume.
Most players(like ipod) have artificial amplifiers built into the DAP(digital audio processor)
The Nook was made as an ereader. it doesn't have a powerful DAP. On some phones they have a dedicated headphone/headset amp which you can crank up.
The nook doesn't.
Therefore, the sound is quiter on these headphones.

Thanks for the great feedback! So it seems like something like http://www.radioshack.com/product/index.jsp?productId=2732095 should work well? I need local-ish as I am heading on a plane Saturday.
I was suffering the same problem. I could barely hear my NC when playing a movie while on the treadmill at my local gym. I bought a tiny little amp about the size of an iPod nano (Amazon for about $20). It turns out that it doesn't bump the volume up all that much. It's enough for my needs, but would not be enough for a plane trip. The little Radio Shack amp you linked to should work. As long as it you only turn it up to say, 5 or 6 (out of an assumed 10), and it's VERY LOUD (while sitting on your couch), that should give you sufficient headroom for a plane trip.
I recall reading a thread at this site about a kernel that would allow you to bump up the native volume. There's been sooo many kernels and updates that I can't recall which one did the trick...

[Q] Razr I Audio Issues (3.5mm Jack)?

I've been having a problem with my Razr I which was purchased around the 11th October from Handtec, and I'm just trying to work out whether this was a faulty handset or whether it's common for the device, or affects a certain batch.
The issue is high levels of hiss / interference when a speaker is connected to 3.5mm jack while audio is not playing. Hard to describe the sound as it changes, however it's somewhere between hiss, ground loop and EM interference.
There's also an unpleasant thump when audio output turns on (i.e. just prior to playing audio) or off (a few moments after the audio output is stopped).
The hiss/interference noise reduces significantly immediately before and after playing audio i.e. it seems to go down to an acceptable level once the audio chip is taken out of 'sleep' mode and made active. I can only assume that this is because a noise cancellation circuit is removing the interference once the audio chip is activated, but that while it's inactive the unwanted signal is making its way down the cable connected to the 3.5mm jack.
This happens regardless of whether the device is connected to wall socket - and I've tested with a battery powered speaker - so this isn't a ground loop issue as far as I know. It is most noticeable when connected to an external speaker that's turned up to a decent volume, but is also audible through headphones. Please note that different headphones will show the issue to a different extent, as the impedance of headphones can vary quite widely. Through small earphones, the sound isn't too offensive, but through an external speaker or decent headphones it's completely unacceptable.
I tried temporarily disabling the MusicFX app and doing a factory reset – no luck with either unfortunately.
There is a report on gsmarena from someone who noticed the hiss. They got a replacement and there was no hiss on the replacement handset.
The thing that's confusing me is that this seems like two separate issues - though I may well be wrong.
1) poor EM shielding and/or cancellation circuitry inactive when audio is not playing and
2) no soft-start / soft-stop when capacitor(s) on the audio chip is charged/discharged and/or DC offset on the signal coming from the audio chip.
The phone's in the box ready to be posted back to Handtec, but just wanted to try and understand whether anyone else has experienced this issue? Just to note that although I haven't been through the returns process just yet, support from both Motorola and especially Handtec so far has been great.

that was me. the replacement was much better. still not upto gnex audio via headphones standard but the positives elsewhere on the phone (vs the gnex) mean i can live with the slight drop in audio quality.
Ah ok that's promising cheers. As you've mentioned in that thread, it's only really a problem when music's not playing and when the audio chip is activated/deactivated. No realm qualms with the quality of the audio chip itself as i wouldn't expect a studio grade dac in a phone, just the interference / lack of soft-start that was the dealbreaker. Fingers crossed my replacement will be from a different batch
my first unit came from clove. my replacement from amazon uk. good luck

In my case the hiss is present only in sleep mode with no music on. I can hear silent thud roughly 3 secs after pressing power button to enter the sleep mode followed by the annoying hiss (only on left ear though). It's not loud at all, in fact it's barely noticeable during the day. It only drives you insane if even subconsciously.

I think this is where the problem lies. First I thought its down to frequency response or even impedance. I think its due to different 3.5mm jack layout. I have no problem what so ever on my Klipsch S4A (10-19khz, 18ohm, 4 rings jack) but on my Koss PRO 4AAT (10-25khz, 250ohm, regular 3ring jack) its simply unbearable.
Shall I try to send it back to Amazon in hope the new piece will be flawless?

i 'think' i had the same hiss you are talking about on my first device. it was certainly noticeable as i mentioned before and unnacceptable i have no hiss on my replacement unit.
3 secs after any music has come to a stop, it sounds as if the internal amp (?) 'clicks' off. that 'click' is/was present on both devices i had but as that does not interfere with and music playing, i don't see that as a problem.
who knows if we are all talking about the same 'hiss' or not
Hiss on Razr I
I had exactly the same problem on first device but on replacement that hiss gone but not all together but 10x better . I have got 64gb micro sd card full of music and I love chillout stuff where any extra noises spoils listening pleasure . Btw my device was prom phones 4 u
Replacement received. Hiss/EM interference and the pop still there :crying:
ooo that is bad luck. as you got both from handtec, i can only assume they had a faulty batch that moto fixed on newer builds.

Well, you first thought it could be the impedance but you forgot it or what? It's quite common problem that not all the amplifiers like all headphones. Can happen with hifi equipments too, but mostly mobile devices just don't have good enough output for high impedance headphones. Low impedance headphones are a bit more battery friendly.
I think people just looks silly walking around with big-ass-headphones. About the same as using tablets as cameras.
Anyway, my phone does have slight hissing noise with 18 ohm headphones, but I can live with it.
Sure I think this is probably not an issue for a lot of people, as I want to be able to output to speakers rather than just listen on earphones.
Agree big headphones look silly, I'd only wear them on long train journey's not strolling around
If it doesn't affect the way you use the phone that's fine, and for those people I don't think it should influence their buying decision. The gsmarena review calls out aux audio quality as an issue though and measures it in comparison to other phones, and it doesn't fare so well. It'd be interesting to know whether the situation's improved in later revisions.
If the interference and pop happened with other devices I'd understand it, but I've had no issues with various other mp3 players, smartphones and tablets feeding the same headphones and speaker systems.
Oh well, hopefully be able to buy in a month or so when I'm reassured they've fixed it.

Yep, phones of friends don't have the same issue. It hasn't been a problem with some models of HTC, iPhone and Samsung that I've tried with the same speaker systems. I imagine there are plenty of older Motorola handsets that don't have the same issue too so it's nothing against them.
Posted this question on Motorola customer care, but recived a useless anwser. I don't know phone internals, but my guess is problem lies in incorects volume regullation. Just like with with connection of PC with amplifier, if you would turn your amplifier to maximum volume and try to regulate volume only with PC volume controll, you would get similar noise.
Here is my post to Motorola: h**ps://docs.google.com/document/d/1R5ngSJzSjmjbsHPTqnEaUDa3h7oR4OC8l13hK-512uI/edit

Extremely low headphone volume

This phone has the absolute worst headphone output. It is SO low. Plugging the device into my car through an auxiliary port is horrible. I can't believe Samsung makes the headphone output so incredibly low on a flagship device. How can they get away with this? It's almost half of the iPhone 5S?
Care to explain a little more in detail? Why 'slow'? Do you mean the sound quality coming through the headphone jack of the headphone jack itself?
I am simply referring to the fact that when you plug in a pair of headphones the output volume is extremely low, compared to the HTC M9, or iPhone. I have tried several headphones and even plugged a pair into a demo unit at best buy. Turn up the volume all the way and it's simply not loud enough. Plug the same pair of headphones into an iPhone or HTC One M9 and the volume output is much louder. I do not understand how Samsung can get away with making the volume so loud. Defeats the purpose of having the phone play music.
Now I have used many many Galaxy smartphones, and while I have complained of this issue before, the S6 by far as the absolute lowest volume. Wouldn't be an issue if a volume mod could be flashed. But we need the boot loader unlocked first.
That's weird, maybe since it's a demo unit, my gs6 gets uncomfortably loud and it's almost on pair with my ipad.

To each their own with sound, I guess. It was enough for me to return the phone.
So this can't just be bothering me.
Once you plug it in, make sure to turn the volume up on the phone. By default, the headphone jack is set very low so you dont blow the external speakers.
Also, try a headset and see if its still low for you. If it is, then its a bad port... if it isnt, then something is up with your aux port or car unit.

I have tried many headphones. It gets loud, but nothing like the iPhone. Very difficult to hear your music in the gym. Samsung should not make the headphone volume this low. It's beyond frustrating for us audiophiles. FWIW, I don't think my phone is defective, I just think its me. Either way, I returned it.

I can understand where you're coming from. I was quite frustrated at first until I started playing with the equalizer and adapt sound. Now it's much better. I've plugged my headphones into the iPhone and while it does get louder it also gets more distoreted.
Have you gone into settings / sounds / sound quality and effects.
The tinkered around with the SoundAlive+ & Tube Amp? Also try using adapt sound to really tailor your sound.
Maybe one of those needs to be enabled to increase the output of the volume, not sure..
There's a post in general secton to increase the volume of the phone. It requires root tbough so be aware.

Dude seriously,, Thank you. I thought i have started having issues with my hearing. The output is so low that when in the subway, there is no way for me to hear my music. Only when i rotate the earpeace in an unusuall position, i am able to hear what i am actually listening to. The worst thing is that it seems to be recognized by u and me only... I don't know what to do and i for sure don't want an iphone..
Yep, ridiculously low volume output from the headphone jack. Compared to an LG G4 on the same speaker set to the same volume level, the S6 output is almost inaudible over background noise in the kitchen. Only way to get any usably loud audio from it is Bluetooth, which has its own set of problems with this phone.
Yes the sound from ear phones is too low. With my previous I9070 my ears used to bleed at 3 with Poweramp but now ven with the Volume turned upto 5 I can barely hear them..!

Well, i had same problem but when i did the adapt sound tune, i did it at home without surrounding noises and heard all the beeps.. I redid it while on the train and heard aboit 30 % of the beeps and now i have a loud volume also disablwd the effects..
My headphones were also not working well. I thought to try some other brands. I searched alot but all were very expensive. Then my gym trainer suggested me to look for SoundMAGIC. I got affordable audiophile headphones online at exclussive offer. The sound is fantastic. I am very happy with it now.
