Headphone Volume Boost - Google Pixel 2 XL Questions & Answers

I'm editing the mixer_paths but the volume is not getting louder has anyone had any success boosting type c headphone volume on pixel 2 xl ?

Use a different DAC dongle.
The supplied one only puts out 300mV on low impedance headphones.
Mixer paths won't affect external sound card gains as far as I know.

3.5mm Stereo Headset volume

i love using my big over the head 3.5mm headphone but for some reason when i connect them to the tp2, it seems as if the sound police stopped by and took the sound away. Is their any part of the registry that is keeping the 3.5mm headset volume that low or are they always going to be that low?
Woa, Bro.First you tell me where you got that 3.5MM Rhodium!!! Please!! I am also using T-mobile.
i'm talking about the adapter
adapter piece.

hi ricky, i use my tp2 through an miniUSB->3.5mm adapter, and it can drive my Sennheiser HD 555 without low volume problem... considering the headphone is quite big... *in term of size, load and impedance*
yet it doesn't sound as great as if i plug my Senn into builtin 3.5mm jack on my sex1... *an eargasm that is*
which Headphone you were using bro...?
alternatively, you have to use Coreplayer to play music since it has (digital) preamp capability, Menu -> Tools -> Preference -> Audio, there you can set your preamp gain you wanted.
hope it helps...
i use the G1s 3.5mm adapter & it doesn't work with my iPod headphones that have the mic on them. The volume is way too low as well.
Did a quick search and wanted to bump this topic. I am having the same problem with the built in 3.5mm jack (Telus CDMA). The speaker actually seems louder then the earphones. This is however just recent. So was wondering if another program may have over written some reg settings and if so, where I would check to change them back and/or boost the audio out. P.S. I am aware of Core Player Pre-amp and the Audio booster and these are not the problem or solution I am looking for
Thanks for any feedback

Mine works just fine, surprisingly
I'm no expert, but I think that these devices don't have the power to drive large over the head headphones. The where designed with in-ear phones in mind I'm sure.
Portable players benefit from portable amps to drive over the head headphones.
Either get some earphones or a portable amp.
BTW my Shure SE530 are very loud with my Tilt 2 and sound great.

[Q] Max loudspeaker output

Can anyone tell me the maximum wattage my T999 loudspeaker puts out on stock firmware. My reason for asking is I am a chef looking for a bluetooth speaker or sound bar to put in my kitchen so I can listen to Stern or music or whatever and all to portable speakers seem to have a max output of 3 watts and I was wondering if my phone already put that out. Any help would be greatly appreciated.

I don't have the exact watts available, but I was in the same situation. The cheapest, loudest, and most effective method was using powered computer speakers. When I used unpowered speakers, there was zerop difference between the loudspeaker and my externals. I don't know if price is a factor for you, but you can find them from 20.00 +
Heres what I bought for 20.00

Does the headphone jack makes hissing/ static noise?

Coming from Lenovo p2 which has similar designs ( both are from lemoto and the headphone jack and antenna seems to be in similar position). Lenovo p2 has this annoying static noise while using in-ear headphone, yes I say in-ear headphone because it won't happen on earbuds, only iems. I guess that's because earbuds have higher impedance? It's extremely audible when playing music at low volume. Anyway back to my original question, does such issue exists on moto z play? I did some Google there seems to be people complaining about this but I want confirmation from you guys. Try listening to some music at low volume using IEM and tell me if there is any hissing noise please. Thanks in advance
Yes it does - more so if you enable the stock equalizer. It is quite obvious if you listen to audio book or speeches in low volume.
Nougat update does have minimized it. Listening to music in low volume is cleaner.
However - the sound signature thro' audio jack is excellent - deep n solid feel to it
No static on any of my IEMs at volume steps 0,1 and 2 playing through Apple Music and PowerAmp.

Yes good decision. I almost always use my jaybird X3 to do away with that irritant.
No it doesn't. I have never experienced any hissing/static with my earphone. soundmagic e50.

These are my work arounds:
1. Installed Poweramp app
2. I use Poweramp in-built equalizer
3. I don't use default equalizer while using headphones.
My headphones:
1. audio technica ath-m50x (headphones)
2. shure se 215 (in ear type)
3. jaybird X3 ( blue tooth)
If you root it (I have not rooted this moto) Arise viper4A is an excellent option.
Please note the sound signature and audio output via headphone jack is excellent. It can even drive audio technica ath-m50x, which has heavy drivers with ease. If you don't use the system equalizer, post nougat update the hiss is almost not there.
This phone is an excellent value for money. I am using it for more than 6 month. It has a heft to it but feels solid in-hand. Buttery smooth, insane battery and zero heating (except while charging). I am very happy!

How about with 18 ohm impedance...sennheiser urbanite on ear

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.

Someone said, we need to buy earphones with impedance of 32 Ohm or more. So when you buy better check impedance, it should be more than 32 Ohms.

That is odd then. As I've said I have 16 Ohms and I don't have any noise at all. Well better take the extra precaution if your budget is 100 dollars

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 got interested on this. I looked for some cheap ones but there is something i dont get, there are 30, 70 or 150 ohms so i wonder which one i have to pick. And some of those even say that they dont work on mobile phones so... I get even more confused.
And want to know if you found some cheap ones with the mic/buttons function

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.

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.

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.
