A2DP Quality issues - Galaxy S II General

I'm not entirely sure about that one, but I've used my sgs2 about 1 hour in my car now and audio quality appears to be inferior in comparison to the N1 I previously used. Did anyone else notice quality issues on A2DP?
I am going to get out my N1 again later today and do a head to head comparison to confirm this.

I've been using A2DP daily in the car since I picked up my SGS2 and compared to my Milestone it's not noticeably different.
I'm using Spotify though, I know the default media player has it's own EQ so it could be related to that.

[Q] sound quality through headphones

I just spent some time at the local T-Mobile store checking this thing out in person. I'm very seriously thinking about picking one up but I have one thing I want to ask you guys that already have one....How is the sound quality when listening to music? If I get this phone, it will be my second android phone but my first htc. I currently have a samsung moment and I detest a lot of things about it. One of the things that bothers me is that I still carry around my outdated ipod because the sound quality of my moment is brutal. I never noticed with the generic ear buds that came with the phone but once I plugged in some quality cans, I realized the phone doesn't have any balls. My music sounds like I'm listening to cheapo headphones even though I have a pair of $100 dollar grados.
I'm a bit of an audiophile so if the thing can't sound high end, its a big drawback to me. I'm so tired of carrying an ipod in one pocket and the phone in another. Been doing that too many years and the idea of getting a smartphone was supposed to cure that need.
Thanks in advance for any feedback!
I have the JH5's.. will listen to music on my G2 for some time and report back. I'm pretty satisfied with the Galaxy S, that has good SQ. My iPad also has great SQ..
One major problem I have with most android phones is that they aren't loud enough. That's the main reason I still carry around my touch. I hope I am able to solve this soon...

This question was bugging me, as I have the G2 on my short list of phones I want, so I went back to the T-Mobile store today and asked if I could see their live demo unit and test music playback on it.
They didn't agree, not wanting me to put an sdcard with music on it in the demo phone, but one of the employees had his own G2 with music already on it. He let me plug my headphones in (Head Direct RE2, not the most spectacular, but not cheap $20 earbuds either) and played a few tracks.
It sounded pretty good for an HTC phone.
Now, granted, these MP3s were not very high quality. They were 128kbps encodes, probably not LAME encoded. But I'll say it definitely sounded better than the utterly bass-lacking Nexus One.
It doesn't sound half as decent as the Samsung Vibrant, though.

Exactly. I know in terms of specs the iPhones don't compare to Androids, but sound quality as I said is a big deal to me. I would tolerate a slightly slower phone for good sound.
As far as people noting that newer Samsung phones have good sound...that's nice to know but I've already decided I can never buy another Samsung phone for as long as I live. I'll spare you all the self-righteous diatribe but suffice it to say my Moment's lack of sound quality is only one of a number of issues I have with it.
That's why I have a Ipod touch 4G
Unfortunately this is all opinion so our opinion of good may not mesh with yours, however I use Klipsch S4s which have been reviewed by many different people as the best in the price range and better than many that cost twice as much...
I listen to FLAC all day on my G2 with these earphones at work and am happy with the quality.
Using the JH5's, the G2 sounds decent for average listening. Not as good as the iPad or iPhone 4, but good enough. It doesn't make the music sound bad, just the bass performance is not as good and its a bit focused on treble.
Kind of like the speaker for the phone.. sounds good but a little quiet.
Plenty loud IMO :/
I have to admit that my blackberry bold 9700 earphone jack yielded better results as far as pandora is concerned to my auxiliary port of my head unit (even with high quality)

I don't know about the G2, but the Vibrant has amazing sound quality through its headphone jack. When tested by gsmarena.com, it beat the iphone on a few sound quality tests and was about the same on all the others. I've never heard better sound quality on a phone and its very customizable and pretty loud.
It's decent. The bundled earphones are pretty good quality, and the controls work flawless, without any lag. Perfect for gym. IMHO if you're using your phone for listening to music anywhere else, you're doing it wrong. At home a hi-fi system is obviously better, in the car... why bother. Unless you have a non-existent (or super ****ty) system in the car, why would you listen to music using your phone?

Yup, the Vibrant/Galaxy S uses a discrete Wolfson DSP ; thus its Sound Quality is superb. The iPhone 4 uses a discrete Cirrus Logic DSP, whereas HTC phones/Qualcomm do not have a discrete DSP, its integrated into the SoC.
So to answer his question, He's still going to have to carry around the iPod.
I've been using the included headset and am very happy with the sound quality and volume.
I haven't tested any other earphones yet.
On a related note, the speaker is only adequate. I wouldn't rely on it. Samsung phones seem to be much better in this regard.
Included headset sucks compared to the S4s, but to be realistic you can't expect HTC to waste money including a "good" headset when 95% of the buyers can't tell a difference or don't care. I hope they continue to include cheap headsets so I'm not paying a premium for a phone with a mediocre pair that I won't use anyway.
Are you using the stock music player to listen to FLAC? It doesn't seem to work for me. Neither does the cube player.
Audio quality isn't the best on this phone. I have a pair of Senn's CX500's and the bass gets distorted when listening to the default player. The mid's are okay and sometimes the highs get distorted also. This btw is coming from music with at least 192kbps bitrate on them.
But still love the phone!

[Q] Audio quality?

Hi guys,
I had a Streak from probably the very first batch from Carphone Warehouse and ended up on a 2nd unit after the first was faulty. On both, running 1.6 back then, the audio through the headphones was pretty dire when compared to other phones I've had like the Samsung Wave, X10 etc.
I'd like to know what it is like on 2.1, if its been improved or anything, as I noticed the audio feedback on GSMArena is really quite positive.
I'd love to hear your thoughts. I listened to audio through some Bose over-ear headphones. Would this have made any difference, maybe the Dell couldn't drive them fully?
Thanks
I didn't try the headphones on 1.6, but the output seems fine on 2.2...

GSMarena audio review

http://www.gsmarena.com/htc_one-review-912p7.php
Unfortunately, it's not as helpful as it could be:
Only compares phone to other Qualcomm devices (no Apple, no Samsung/Wolfson). And they consistently ignore Qualcomm shortcomings in s/n to other devices.
Don't tell you if tests were made with/without Beats. Both would have been nice.
Would be nice if they did their Android tests with standardized player, e.g., Poweramp or Neutron. But no.

I hope not. Had a N4 of those for a few days, and it was among the worst music phones I've ever heard. I don't think it will be though.
p.s. Interesting to note how different the GSMarena was for N4 than what others found. It's review stats were not bad. Mine was much closer to the supercurio frequency response chart (See the N4 audio thread), with rapid treble falloff. After that, I take everything from GSM with a grain of salt.
Something to do with the snapdragon chip, I wish I could remember where I read it:crying:
Visited P4U in Market Street, Manchester, where they had a silver HTC One (unfortunately locked in a guard thingy).
The speakers were pretty impressive, compared to my friend's iPhone 4S, Galaxy Note 2 and my other friend's Galaxy S3...And of course much better than my Desire HD.
Only could test music that was already on the phone for demonstration purposes, so it wasn't really a direction comparison, but there's no doubt that the HTC One's dual front facing speakers are louder (duhh) but also clear.
The speakers and sound are so good IMHO that I have been using it to play radio and music around the house.
None of the on-board music seems to showcase the tone and range very well, but listening to some classical, talk radio and pop music just sounds amazing for a phone. You don't even have to crank it up to full volume to hear the quality of reproduction.
It's not going to replace your music system, but playing music in the kitchen or office for example with the speakers directly facing one person is very impressive.
This is one of the standout features for the phone, and I really get why they ate advertising it on TV.

I find the speaker test on gsm arena nonsense or they have a faulty device because the one is far louder than phones whihc they are tryign to claim it is on par with like the s3, one x or one x+ for example and it is far louder than a note 2. yet in certain test like rining for exmaple they claim to note is is louder no way.

Head Unit with best audio quality

Hello, Im new here. Have always used an iphone. Only ever had a smasung s3 for a few months and was presently surprised by how solid android has become.
Anyways, I am looking to put a double din HU that runs android in my car.
I have ordered and used the Joying headunit 4.4.4 and it was great except for a few points:
1. Doesnt read address book from phone via bluetooth, needs to be imported.
2. SOUND QUALITY.... is not great. Not unbearable but barely passable in my opinion. And that is with the bc06 bluetooth. Running mp3s from the HU directly was slightly better/clearer. But I mostly stream audio from my phone, so I was not happy with the audio quality. I played around with the EQ and got it as good as I could and was slightly dissatisfied. Very boarderline.
3, UI is difficult to use in clutch situations. Would be nice if there was an app\overlay that would give me just a couple of high priority apps on screen within reach. Im sure this is easily done, didnt spend much time trying to get it to work.
I see that PUMPKIN is coming out with a unit that uses the parrot Bluetooth card that should bring the bluetooth audio quality up to max. Leaving the preamp to be the weakest link.
How are you guys dealing with this? And do you think I should spring for the pumpkin that will give me good BT quality? Also, are there any good EQ apps I could use to fine tune the audio to get maximize audio quality?
I really like the headunits that run android and cant live without all those other features but the audio quality really needs to be addressed.
Here is what Ive used:
(cant post links yet)
JY-UQ130 Joying
Here is what I want to buy now:
11-RQ0259E-US-A Pumpkin - only available on their site for now, will be on amazon soon.
Let me know what you think and if rooting it would help me get the most out out of the pre amp module.
I also have an external 2200 watt amp that I have in my car, so maybe I could tune that? IDK...
Thanks
glad i read this before buying the joying unit for my VW. looking for something with decent audio quality as well.
none exist at the moment, sadly. the only way to deal with the poor sound quality of these HUs is to buy an external DSP & use that to process your sound instead. minidsp 2x4 is the cheapest option to accomplish this ($100).
Hi,
I've just found MXTRON HU with dual ST sound processors.

Still only dual core 8GB and only 4.2.2. The question is what do they mean with dual sound processors? Because the standard KLD has
dual sound processors too, sometimes with the brand ST.

I've bought that unit and the sound quality is not okay even if they are using parrot. The two microphones
are still in parallel with lower sound quality. It's equal to my modified KLD. I.e. no improvement.

What's the sound quality like if you use an external DSP? Is it as good as a good car audio system, or is it just smoothing over the cracks?
Yes the sound quality is not great, the rca pre outs are super weak, i tested mine the pumpkin from amazon and the voltage is on like .8 VAC rca i bought a line driver and that got my voltage up to 4.2 VAC rca which now my bass hits like before.

Personally I still feel like something is missing. It is absolutely better, but a DSP can't generate frequencies the sources doesn't produce. So I still would prefer a HU from someone known to produce high quality audio. But the android units have all the features I want so I just go with it.

Darn it - I wish I'd seen the stuff on here before buying it.
I really notice the frequency cut off - it's like listening to a really badly chopped low bitrate mp3.

yep, huge disappointment to say the least. with the amount of time and energy I've put into my system, I'm still not completely happy w/ the results. I'm still learning how to tweak it, so I am certain I can get it to sound better, but I guarantee a high quality audio HU would not need near this much TLC.
Most probably don't notice missing frequencies, but a critical listener would. I own some high quality headphones, so I know what my music is supposed to sound like, and its just not there.
Think I'm going to add a line driver to my signal chain next, as the pre-outs are a measly 1V (and the DSP chops that signal up even more). Hope that does the trick.
Any point in doing 7floor's mod and using an external dsp or are they achieving the same end?
theoretically flattening the EQ should remove all custom audio processing, making 7floor's audio mod useless if you use an external DSP. However, b/c of how suspect these units handle audio, I wouldn't even be surprised if a supposedly flat EQ on a non-modded unit isn't really flat.
But yes, they are achieving the same end. Of course the internal DSP, even w/ the audio mod, would not be near as effective or give you as much control as an external DSP.
most of the time I read about sound problems, it is due to using Bluetooth. Is the sound still bad if you use Google Play on the actual head unit?

It has taken me soundproofing, 3 sets of frontstage speakers (currently on my third set), an amplifier and a good subwoofer to improve sound quality in my car and a 7floor mod with these units. There is always something to improve in the sound in a car and I am leaning towards a decent headunit now. The radio tuner and sound quality on these units are its' weaknesses it is such shame as the OS is great.
I just read that with Android Lollipop it is possible to connect an external DAC via USB:
http://www.phonearena.com/news/Android-5.0-Lollipop-supports-USB-DAC-audio-devices-we-go-ears-on_id66399
Would that be an option to have better audio quality? Is there a USB-DAC which would be suitable for a car?
Pumpking as a new one coming out next month, apparently with a new DSP with better audio quality:
https://www.youtube.com/watch?v=poAkdg6Y3Wc
nice find checksum. if the price is right I may pick one of those up to replace my current unit. I wonder what the pre-out voltage will be.
Do these devices have the same sound card? I need some of the apk of one to control sub vol on the Joying
I think that sound quality playing mp3's on these units is excellent.
On my Joying unit, while the bluetooth is not the best in the world, if you are playing mp3's off an SD with MediaMonkey, or PowerAmp it is VERY good.

Stupid mistake I made choosing Bluetooth Dac/Amp

I was looking for a relatively cheap Bluetooth DAC that could do the job for me. One of my friends were using a AK XB10, which I tried a few years ago when he first got it. The DAC performs great when paired with most of the phone I was using. But I forgot Aptx HD are a Qualcomm IP and it didn't work with my G950N with Exyons SoC (but strangely Aptx works)
I only found out the problem after I use the DAC for 15 minutes. the sound quality is really disappointing. And I started to google a bit and learn the Exynos don't have Aptx HD, and all the way the xb10 is using Aptx. The difference was so huge that my 24bit flac sounds worse than 192kbps MP3. And sadly the AK xb10 didn't support LDAC.
So now I have to buy another Bluetooth DAC now.

Check out the FiiO BTR3, it supports LDAC which should work regardless of processor since it's in base android and also theoretically higher quality than aptx.

I bought the earstudio ES-100 from Amazon, now waiting for it to arrive. It is slightly more expensive than the BTR3 and xb10 , but reviews suggested it should sounds better.
Speaking of LDAC, I read a article online about LDAC vs aptx HD, turn out that most of the time LDAC is default at 660kbps, not the advertised 990kbps. And the sound quality when using 660kbps is not necessarily better than atxp HD.

While true, you can also go into developer options and pick a specific bitrate to use, and considering it's going to be in a car with maybe 2-4ft of range i don't see 990kbps having issues.
The article makes it sound like it's a great big hassle for regular users, but I posit that regular users won't notice any difference in quality if they're just playing "high quality" Spotify, and if you do care enough to play files at high res you should be familiar enough with tinkering to tap a few buttons.
Now the better argument is whether the earstudio actually sounds better than the FiiO, and basing off of reviews that compare the two directly that answer seems to be that it's not better but a little different, though it does have some nifty features that the FiiO lacks.
Then again with it being in a car it likely won't matter since they're more useful for headphones.
What I wish someone would do is make something like either of those devices but without a battery so that it doesn't stay connected when the car is off.

Think in a bit more on that, it might be just down to which amp works better with which iem. Since I had no where to test the earstuio, I can only cross my finger and hope it works well with my Westone w4r.
BTW, I wish my car is quiet enough so I can care about bluetooth audio quality. The tyre noise is just bad that it doesn't matter anymore. And only two door speaker doesn't help ether.

I think some sony head unit already support LDAC and didn't cost much more than your FiiO, if car audio is all you want. And you don't have to amplify the signal twice (or is there a line out on the FiiO? Idk)

Fair enough about road noise, I'm hoping to fix some wind noise at some point. Tires are already as good as can be pretty much, without being wasteful, you always want the best you can get though, it's arguably the most critical part of your car in emergency situations (having enough grip to break and stop, emergency lane change, or accelerate and gtfo)
Issue with the head unit is that most modern cars are notoriously hard to put head units in. My car is a 2012 and I need like 2-3 different adapters that add an additional 80-120 to the cost, plus the time to install, all to get a piece of my dash to stick out like a sore thumb since it's not a factory look.
And even then, the head unit itself would cost at least 100, whereas a simple USB powered dongle with just line-out and minimal processing I think could easily be made and sold for maybe 50 to max out bluetooth quality, and it would be easy to take with me to another car rather than having to break down the dash just to get the head unit out.
Personally I'm eagerly hoping and awaiting for SBC HD (aka SBC Dual Channel Audio) to be merged into AOSP and released as part of either Android Q or whatever comes next, as this would increase the max bitrate to 512kbps for all bluetooth devices made since 2007 whereas devices made after 2015 would have effectively any birate they want while using the SBC Codec. Free audio quality upgrade for pretty much all devices, especially those not supporting AptX or better.

I will likely attempt patching the library myself if rooting ever becomes available for the S9+
