[Q] Hiss while sound playing?

Anyone else noticing hiss through the headphone jack when sound is played?
Steps to reproduce:
Use earphones
Get sound to play shortly or at low volume (a notification works fine)
I'm hearing a good amount of hiss through earphones (loudness depends on headphone sensitivity: much less audible on my stock ipod earphones, much more noticeable on my Shure IEMs)

nope...sitting here as I write this listening to music using Samsung Focus S buds. NO hiss at high or low volume.
I tried a koss headset this morning and my phone rebooted.....but no hiss.

I have also noticed the hiss whenever watching movies or listening to music. Depending on volume, it can be pretty strong sometimes.

I'd reboot myself too, if you plugged Koss headphones into me...

Cuz you hava a good ear piece, lmao

Yup, my senn IE8s and Ety ER4p are both producing noticeable hiss at low volumes, sounds like the gain is way up and the line level is low.
There were some amazing KOSS headsets back in the day, especially known for their electrostats. I'd pick a KOSS ESP950 over a dr. dre beats, BOSE, HK, or whatever else is popular out there these days.

+1 on the Koss. I used to use Radio Shack Optimus - those were all Koss - and some of the best sound headphones under $50 I have ever owned.
I have Sennheiser CX300-II's and they are quiet compared to other headsets and bass response is sub-par (compared to what they sounded like in my iphone). My Klipsh Image One's sound awesome, but the mic/volume don't work (and the AHJ detects and then disables the phone's mics, so lots of features 'break' with it, trying a Fiio LU1 adapter in a few days). My rocket fish cheapos work the best, and sound the most 'normal' with good bass response, general sound - however they hiss - which is less noticeable at higher volume!

Static sound from headphone output/speaker ?

Okay, so I just want to check if this is normal. If someone could confirm this, I would appreciate it.
Whenever a sound is played on HTC 10, I hear a slight little static sound for 3-4 seconds, and then it disappears. It happens when I use headphones or speaker.
My phone is stock, haven`t messed with some advanced audio settings.
The best way to check this is to go to settings --> Sound & notification --> Notification sound.
Play one of these sounds.
If played through speaker, put the lower part of the phone (where the speaker is) to your ear, you should hear a very slight static sound that disappears 3 seconds after the sound is played.
FIXED : It is kernel related, flashing Elemental kernel v18 (which has Analog gain headphone feature) introduced static noise, reverted back to v16, no static noise anymore.
Credits to @Blue305 for pointing it out and @mosincredible for the helpful posts!

My ear is not the best, but on default settings , without audio gain or audio analog gain, i cannot hear static. Have you modified those settings?

Tho, the speaker part of the soc codec is not in relation with those settings, so just ignore my previous comment.. so basically I can't hear static, but my ears aren't the best, especially with low volume noises.

Thanks for the reply, but no, I have not modified hedphone analog gain or volume gain settings. The static sound can be heard for 3 seconds with headphones as well. Tried 3 pair of headphones, the slight static hiss is always there.
I wonder if this is normal or not

Okay, can someone please check if he has the static sound from speaker/while on headphones ?

Just realised that the static sound/hiss happens only on low impedance headphones, like the HTC headphones that came with the phone, Sennheiser Cx400 and all other average in-ear headphones.
Can someone test this and report back if he has the static sound for 3-4 seconds when a song is paused ?? Or when a youtube video is paused

I can confirm the static is there in the exact way described in the original post. Comes on for 3 to 4 seconds when audio is paused. Tested on stock ROM with latest unlocked US firmware using HTC Pro Studio headphones, Sony EX90s, and the headphones that came with my iPhone 6s.
Edit: The problem is worse in games. From Riptide Renegade to Real Racing 3 to my little boy's Lego games, the low level static is present and does not drop off as it does with video clips and audio.

So you have it as well on a stock phone.
It's worse for me too in games, like for example "Smash hit", I turn the volume all the way down in both game and phone and I still hear that whitenoise static sound. When I go back to homescreen, I hear the static for like 3 seconds more and then it ends Until I go back to the app

For a phone that's reason for being is primarily audio, this is an unforgivable oversight and flaw (in my opinion). Will be returning to HTC.

I expected it to be impedance related and it is. The higher up the impedance latter I go, the more faint the sound is. ie8 > t51i > m50 > dt770 80 ohm > hd600. I prefer higher impedance headphones anyway so this doesn't bother me as I rarely listen to my ie8. I'd give this same test to an iPhone but is have to wait until I get with the girlfriend.

Your sennheiser IE8 headphones have the same impedance like my sennheiser CX400 (16 ohm).
So you hear static as well on these headphones ^^ ??
Maybe it is impedance related, but then again, why would I need to have 500$ high impedance headphones to get rid of static noise that should't even be there. Also, I like my headphones to be discreet, not big, and those are always low impedance (16-32 ohm). This is a serious flaw in my eyes.

Tried the same audio (video, music and games) on my iPhone 6s with the same headphones (listed in my previous post) and had no issues whatsoever. Very unfortunate. The HTC 10 is a beautiful phone and I want to keep it, but this is something that wouldn't happen on a cheap phone from Target. Insane their engineers did not pick this up.

Well, I'll take my statement a step further. Your ability to hear the sound is impedance related. I believe the actual sound is software related. I've experienced it on the past 4 phones I've owned. With the phone that drives my headphones the weakest also being the phone that has minimal noise.

If weaker happens to be aligned with less noise for very low impedance headphones, I'll take the HTC 10 over other options. Does the iPhone drive high impedance headphones to same volume as the 10? And when you're bringing a different OS into the mix, you have a lot of other variables such as how the software handles outputting a sound.

I have the same problem with my Sennheisers CX300 II on elemental kernel.. the funny thing is I've only start to have it this issue after they started playing with the analog gain..

Bingo! After reading this, I went back to v16 of elemental kernel which is before the analog gain feature was added and the static is gone even on my ie8.

I had the same situation as Blue305. Was on cleanslate kernel and then flashed Ex kernel to see battery life and everything, after that started noticing static noise like everywhere.
I thought it wasn`t kernel related
V16 Elemental kernel with no analog gain features fixed it
@ryansc375, do you possibly also have elemental kernel installed or something similar ?

Hey everyone, just finishing up a long day with the family. Read all the posts and will report back now that I have some time to geek out. Hopefully the static demon can be exorcised!

Okay, so after a full wipe and running the latest RUU for the unlocked U.S. version, I can say that the static issue is gone on my phone. I'm not sure what changed but I'm happy it's back to normal (on stock). If I root again and want to install a kernel I'll be sure to use v16 of elementalx or one that doesn't mess with the audio settings.

Tested v19 of Ex Kernel. Static persists. Staying on v16 for now unless a new setting in Ex Manager comes along to fix it.

Question about headphone output quality

Trying to get an idea of the quality of the output of the headphone jack. My Asus Nexus 7 (2013) has a fairly noisy output (lots of bus noise) but my Sony Z3C has very clean output.
There is a you-tube video out there that indicated that it's fairly powerful but did not indicate the quality of the output when used with sensitive headphones.
Anyone have any insight?

It might be pretty good. Only moto phones that disappointed me were/are the g series.

It's great!!
I use Neutron music player app and Harman Kardon BT headphones. I upgraded from LG G2 which used a Wolfson DAC and the first thing I noticed on Z Play was the LOUDNESS which I believe would be better at driving power hungry headphones. I also find the stereo imaging pretty awesome. The music feels more lively and energetic even on the flat eq settings.
But if you're an audiophile who mostly listens to lossless music, I'd strongly suggest Neutron or JetAudio. (both paid) This is because the hardware doesn't have a native support for many formats and therefore the need for S/W decoder arises.
I had some songs that wouldn't play on GMusic but did on Neutron. :/

Thank you for your input but your Harman Kardon BT headphones just the BT stack if I understand corrctly - so they would not be affected by bus noise, DAC/Amp etc... Have you tried with normal wired headphones?

If you are used to listening at lower volume thro' headphone jack you will notice high level of radio interferences/ background static for sensitive in- ear phones. Reason: the antenna band is too close ( a white strip over usb type c port)

Yep, I've noticed this as well

I'm using plain regular Apple EarPods (from the 6S) in my Z Play and it's gotta be one of the best phones I've listened to music on. I've heard details in the songs that I haven't heard in any other phone or speaker before!

I noticed this but to be honest: I have to turn up volume very loud (can't hear normal music with this) and wait until the songs faids out. Than, at the very end of the song I could hear some noise. I use very sensitive and rather high end IEM's (UE 10 triple fi) with low impedance (32 Ohm).
So yes there is some noise. But normally you should never hear it.

I went and installed Jetaudio + . Wow it puts out up to 192/24. There is a dropdown of current processing. I have the same Apple pods. There is a Bongoivi DPS where the earpods can be dialed in. Sans all other processing the sound is stunning. I did also set Gplayer Equalizer to off and disabled as suggested in another thread. Strange advice this is but have others found it necessary?
What output amp is in this? Surely a bipolar "chip" of sorts.
Try out this player on our phone. Do check out the pics of the likes of my source material.
The text file about an amazing 24/192 FLAC.
BTW this player adds 1 percent volume adjustments yet there is no easy way to "finger" this fineness on the app's slider

High impedance earphones.

Suggest me a good in-ear earphones under $100 with high impedance. I want to get rid of this horrible hissing noise.

This has nothing to do with impedance. I have in-ear headphones with 16 Ohm impedance (JBL T110) and there's noise as well. But I have on-ear headphones (Connect IT CI-235) and there's no noise at all. The issue is how much voltage can the headphones take. So I would recommend you to get some on-ear ones and if they're above 20 dollars they should do the job.

Actually I do have 16ohm impedance earphone. Sony EX-15AP. Hissing is very much audible.

It's really weird, I have never heard this hissing.
I even just tried a pair of free ones I was given free on a sightseeing bus, quality is rubbish but still no hissing, I get a crackle if I twist the jack but that's it.

Problem is combination of low impedance and high sensitivity - which is pretty much case for majority of IEMs. Bigger headphones are often less sensitive so they do not tend to have the hissing issue. For 100usd, I would suggest buying any headphones you like + iEMatch impedance adapter (https://ifi-audio.com/portfolio-view/accessory-iematch/) - particularly if you need mic/buttons.
Edit: per iEmatch manual, mic/buttons on headphones will be disconnected by this adapter, so better verify with Ifi company before purchase.
Budget version would be ChiFi headphones (KZ, Senfer, ..) + cheap impedance adapter, but beware that this combination doesn't allow usage of cable with mic/buttons. I am quite happy with the budget solution..

Unfortunately I hear absolutely no difference in the hissing or overal volume of headphones. I'd say it's only a placebo "fix".. On the other hand, decreasing the headphones gain via custom kernel masks the hissing quite effectively - hissing is still the same, but as you have to turn up the volume, Signal To Noise ratio increases as well and you can't hear the noise over music. Quiet songs/passages are still bad though.

I guess it only changes the gain or amplifiction. But my piston 3 almost gets no hiss with that fix. Super noisy without.

70 ohm should be fine, it will remove pretty much all the hissing and keeps overal volume high enough. Or there is an even cheaper and more versatile alternative - cable with analogue volume control (https://www.ebay.com/itm/131489435905). By turning the volume down, you effectively increase the impedance and hissing disappears. And you can fine tune it to each headphone. Though still no mic/button control.. I have similar one with button and mic on the cable and it makes wonders, but I purchased it years ago and can't find it anymore. Try to look for one in your favorite shops, you might have more luck.

No idea what it does, on my phone nothing audible. From the description it should do what custom kernel with sound control does - only mask hissing.

Just get a pair of Apple EarPods. They have an impedance of around 40-45 ohms and work great.

[DISCUSSION] Headphone Jack performance

I wanted to start a thread discussing the performance of the headphone jack. I'm a bit disappointed considering Sony's audiophile history with their walkmans and LDAC codec.
Yes, I'm nit picking about a $13XX dollar phone but for this price, I was expecting a bit more that just average performance.
For comparison I do have a LG V40 with it's quad dac and it powers my audio technicas perfectly fine with High-Impedance mode.
On the MK ii, I don't get the full sound with out an external dac coming into play.
I'd like to ask other MK ii owners if having just a headphone jack is enough to power your earbuds/iems/headphones.
Going to do a bit more in detail research within a couple of days but I think Sony just wanted to slap a headphone jack just to say it has one.
Ps- I'm no audiophile but having a full sound for the headphones I have is a must.

Thank you! This thread is very interesting.
I have reduced hearing and I badly need a smartphone with high-output. My LG V30 with it's QUAD-DAC has no problem giving me enough volume even on my favourite pair Hifiman HE-4xx.
I was hoping that Sony 1 mk2 was an alternative, but maybe not................ ?

You may want to make the distinction between headphone jacks that can and cannot drive high impedance headphones as a headphone jack that can't can still be good as in clear, little to no distortion with good response and sound reproduction.
In this case its more like LG's has gone out of their way to include a dac that can power high impedance headphones (which is rare in the first place, in addition to the jack being rare) so if high impedance headphones usage is a top priority, then sticking to LG would be recommended.

I have a Meizu Pro usb dac which has a good reputation. The volume of the Meizu is a bit higher, but the audio quality of the Sony is equal. You just have to increase the volume 2 or 3 notches. The Sony uses the Qualcom dac and excellent Cirrus amplifier chips. I use my Beoplay H6 over the ear headphones for listening. The volume being a bit lower is no problem for me, I still can get serious hearing damage if I want to.
The audio is detailed, excellent channel separation, noise is undetectable.

You may want to make the distinction between headphone jacks that can and cannot drive high impedance headphones as a headphone jack that can't can still be good as in clear, little to no distortion with good response and sound reproduction.
In this case its more like LG's has gone out of their way to include a dac that can power high impedance headphones (which is rare in the first place, in addition to the jack being rare) so if high impedance headphones usage is a top priority, then sticking to LG would be recommended.

Yeah LG has done the headphone jack justice, but I was expecting a bit more out of the mark 2 for it's price point.
Like hi-res audio. I get it's mainly a photography oriented product. I mean I guess I got used to only using half of the volume steps provided by the LG phones.
I just had high expectations out of Sony in the audio department. Great camera. As for the dac mentioned above, i have a couple so I'm not too worried about getting any more of them. I have a couple of headphone I can try out besides my audio technicas.

The audio capability of the phone is lacking
Bluetooth volume is pretty poor even though it's decent quality
The 3.5mm Jack absolutely doesn't have that much power to drive much more than basic iem 8 to 16 ohm level. Can't push my 150ohm cans at all

Definitely louder than the previous phones. I'm just happy that the jack is back. I did notice a difference with bluetooth vs wired on WH1000XM4. Volume was definitely louder on bluetooth, but can really notice the difference in quality despite LDAC. But that's just me.

But it does have Hi-Res audio. Volume is a bit lower, but is also the curve of the volume control. With the LG the volume control is linear, with the Sony starts to increase real slow, until over half of the volume.

Yeah volume has to be over half way to start making decent sound. Regular buds are fine though. I have some kz iems and it's fine with those. Just higher impedance isn't for this phone.

My Beoplay H6 headphones have an impedance of 30 Ohms. They work great with the Sony. I can't compare, these are the only wired headphones I have.

The audio quality is perfect with my XBA-N3AP or WH1000XM3

Oh snap, how are the XBAs?
Currently, I'm using AKG N700nc2( using them wired )

XBA are amazing, well balanced and no extra bass like many earphones.
With an upgraded cable it's even better [emoji106]

I think using its headphone jack to push N3AP do not working perfect, the human voice is low, the sound ‘s analysis goes bad, compare to use usb-3.5 dac line. I use IE60.

Poor volume, I can still get hearing damage by the levels of volume here.

I haven't tried with a dac, I will try to compare with my XA50ES

Apologies for replying to an old threat, but what became of this? The link is now dead unfortunately. Was it an actual improvement or deleted because it was non-functional? Thanks.

Try to dm peter. I didn't have a chance to save this.

Sony Xperia 1 II most probably uses a Qualcomm audio codec. Can be their flagship Aqstic WCD9341, a dedicated audio chip. Only a proper tear-down will reveal the details. As I found out this audio chip contains a very good DAC section and can produce nearly 1 Vrms at headphone out when implemented in high performance mode.
