in a quiet environment it will hurt your ears at full volume. but try listening thru headphones in a car on the freeway, or in a crowded street, or on an airplane. the outside noise forces you to listen at higher volume, which may not be adequate if the level isnt loud enough.
[Galaxy S II General] =dave=:
some days ago i listened in the tram, which was full with kindergarten-kids, talking and screaming, ... and i couldn't turn the volume up higher than ~11, otherwise it would have hurt my ears ;)

i have a pair of sennheiser cx 270 in-ear, i know that they are not as good as many others, but they are also not the worse ;)
[Galaxy S II General] bendispo:
Just got my sgs2. I'm using very sensitive, detailed IEM's (Ultimate Ears Triple fi 10), and I'm both impressed and fairly disappointed. First off, the sound is detailed, and the bass is both clean and authoritative.

However, I can hear background noise even as I scroll across the desktop or open/close apps. It seems as if processor noise is being picked in the audio path.

Unfortunately, it seems as if the problem is less the DAC and definitely more an issue of poor EMI shielding. Don't know if this can be fixed, but it would be a shame... :(
[Galaxy S II General] barsk:
The volume you get is dependent on the kind of headphones used. Some headphones (often the higher quality ones) are heavy to drive and thus needs more volume to sound loud.
[Galaxy S II General] barsk:
This is bad news. I have the same issues in my laptop, and there is nothing to do about it... It is a design flaw of the hardware.

Still, there can be differences between different samples of the phone I guess. And some are more sensitive to these kinds of things than others. For instance if you listen to loud music you will most likely not hear it ever. In the pauses or in silent passages of the music it may be heard. But modern music does not have any silent parts in them...
[Galaxy S II General] slitch:
The phone sounds great, just at low volume.

Its very noticable when you plug it in an amp or car stereo.

when I hook mine op to my car audio system the distortion is just awfull.

If supercurio works his magic on the SGS2 like he did on the SGS then I'm sure it will improve alot.

Remember how the SGS sounds stock? Like my 15 year old discman.
[Galaxy S II General] BarryH_GEG:
I have a pair of Shure 530's which are pretty sensitive and while listening to an a cappella Annie Lennox song at lower volume opened and closed apps, connected and disconnected Wi-Fi, browsed the web, and created a document in Docs to Go and didn't hear any noise from the phone. I did hear the typing clicks and other sounds I have turned on in notifications but they can be turned off. So, maybe it's your particular phone.
[Galaxy S II General] bendispo:
Thanks for the info Barry... could you try doing those tasks without any music playing whatsoever and let me know if you hear anything? I can't really hear it once an audio track is playing, though it's quite noticeable (with volume around 11 or so) when nothing's playing in the background.
[Galaxy S II General] BarryH_GEG:
Totally silent (except for system sounds) at max volume. I tried it on a pair of Razer's I have and they performed the same way.
[Galaxy S II General] bendispo:
Hmm... Interesting... I wonder what the impedance on your phones are....
[Galaxy S II General] BarryH_GEG:
The Shure's:

Speaker Type

Triple High-Definition MicroDrivers

Sensitivity (1kHz)

119 dB SPL/mW

Impedance (1kHz)

36 Ω

Noise Attenuation

Up to 37 dB

Frequency Range

18Hz – 19kHz​

The Razer's:

Frequency response: 20 to 11000 Hz

Sound pressure level: 110 dB

Impedance: 17Ω

Max rated input: 20 mW​

Guess which cost more ;)
[Galaxy S II General] supercurio:
Airplane mode doesn't stop the CPU ^^.
[Galaxy S II General] supercurio:
The output volume in dB in your ears totally depends on headphone's impedance & sensitivity.
[Galaxy S II General] kersh:
Well I am using a Sennheiser IE8 and I don't have either noticeable hiss even at max volume, but yes, they have lo impedance 16ohm

Specs

Driver: dynamic

Impedance: 16 Ohm

Sensitivity: 125 dB (1 kHz, 1 Vrms)

Frequency response: 10 Hz – 20 kHz
[Galaxy S II General] supercurio:
On this device, the hiss is low which is a good thing (SNR is nice)

Hiss don't depend from the volume chosen because its 100% digital.
[Galaxy S II General] kersh:
hmmm strange. Why then I have hiss in my clip+ rockboxed if I put the volume at maximum without playing anything but no on low volume?

Oh, on other things I dont have any strange sound when I am using other apps while I hear music, no background noise of any type.
[Galaxy S II General] supercurio:
Nothing strange here, phones turn off the audio hardware as soon as possible to spare battery. I guess Rockbox don't bother (or cannot)
[Galaxy S II General] -jen94ek-:
PLEAS CLOSE this tread

Close this tread until voodo or somethink.

LAst time SgS2 is poor-terrible MP3 player if you talk about sound quality.

Samsung doesn' care about built best mob with best mp3 chip in it.

/Thats why they have on market one of the best phone and one of the best ''MP3-4 players if you talk about sound quality,,

Who likes samsung MP3-4 buy a galaxy wifi4 or 5 or q3
[Galaxy S II General] supercurio:
I see no valid reason why this thread should be closed.

For people wanting more info, accurate analysis I'm preparing ATM a detailed analysis for you, with measurements & facts.

It takes some time to be written properly though.

Incoming Galaxy Player run the same audio codec as Galaxy S II (Yamaha MC1-N2) so I assume they suffer from the same issues (or some)
[Galaxy S II General] jangomango:
Jeeez how rude are some people ? "close this thread" you do know Supercurio does this for no reward dont ya? This is his post to discuss the sgs2 and its sound performance.. Lost for words...
[Galaxy S II General] andeeroid:
this guy is probably drunken...........
[Galaxy S II General] saveferris:
Hey Frenchy....you shouldn't have to explain yourself to total d*cks. You're doing a top job and the majority of people on here appreciate all your time and effort.
[Galaxy S II General] HumanoidTalking:
You must of out of your mind, Such discussion made SGS a wonderful device and DEVs like Supercario are the backbone of such discussions... These guys are Volunteers and whatever they do for us is Amazing.. If you believe you have better information, please start a another thread..

lastly, such discussions give us MODs, Roms, Fixes and hacks, no one is full time here so people discuss and share knowledge to come up with better results.. We could have started to Block you from XDA but its a public forum and we respect each other and their work.. So Just STHU
[Galaxy S II General] jay_993:
I personally would hesitate to think that samsung got sound issues on those devices since the Sound Alive tech is supposed to be THE difference to differentiate phones n mp3/4 s.
[Galaxy S II General] cpu98:
http://samsungtomorrow.com/1211

It says Korean galaxy s2 will recieve some improvements next week.

'Cleaner sound while playing videos, musics.'

Interesting!
[Galaxy S II General] supercurio:
Thanks for the translation :)

Related to the mail I sent yesterday @Samsung KOR HQ or not ? :D

Or maybe to the phone call + mail with Yamaha, how knows.

Anyway we'll see.
[Galaxy S II General] B3311:
jen94ek

Supercurio answeres your diatribe with politeness, reasoning and a grace that you don't deserve.

I'm certainly not going to. Troglodyte. Learn to spell, stop trolling and come back when you have 0.000000000000001% of supercurio's digital music knowledge. That should take you about 6880800 years, hopefully.
[Galaxy S II General] kradcliffe:
I agree. Supercurio has taken his own time and carried out some fantastic work so far, FOR FREE!

Can you quote that number in Binary please :)
[Galaxy S II General] Miracle1980:
mmm just Korean's models?

Do you think that SGS2 will arrive to the quality of a Sansa Clip\Fuze with some tweaks\improvements?
[Galaxy S II General] David Horn:
What an idiot - though going by their username they're only 16 and guessing from the misspelled "somethink", they didn't actually buy their phone, just mugged someone and took theirs.

Correct spelling is, of course, "somefink".
[Galaxy S II General] Woodend:
If so, just bombard them with mails,till they get it right ;)
[Galaxy S II General] B3311:
1101000111111100010000011010001111111000100000.

Think that's right, Google is for maths wimps, sure someone will correct me if necessary... Maths A-level in 1981 - long before it became an exam a 12 year old could pass;) Do you young people remember log tables?

Edit - back on topic. Supercurio made the SGS listenable, and I've every faith he can do the same withe SGS2. Still testing, but getting no background noise when other apps are open as others have reported.

Lot of distortion at volume 10+, and the soundstage is way too narrow (wasn't crash-hot on the SGS either, to be honest).

I use Sennheiser IE8s on my Cowon s9, so probably spoilt. Not an audiophile as such, but I know what's good/bad. And Le Homme will make our 2s good enough, I'm positive. I'm prepared to wait anyway.
[Galaxy S II General] B3311:
I liked his/her - na - its will do - request to close this tread....
[Galaxy S II General] Gilgehmesh:
I'm also appreciative of your effort, supercurio. I like to have good sound. Also, it seem the audio "improvements" to the Korean Galaxy S II will be distributed through Kies.
[Galaxy S II General] B3311:
I know that name - were/are you on iaudiophile?
[Galaxy S II General] Gilgehmesh:
Nope... not with that username.
[Galaxy S II General] barneypooch:
Got my phone yesterday . Im using Shure se 530.

I was HORRIFIED when listening to quiet piano music to discover that there was a constant background of crackling etc.

However, I changed to Poweramp and that's all gone away. So relieved. I thought it was just terrible EMF shielding.

Having said that, the sound is not as good as my Sansa clip.
[Galaxy S II General] B3311:
The clip - like my S9 - are top music players.

As much as I admire supercurio's work, I don't expect a phone to ever sound as good as a dedicated player such as ours. The best vanilla SQ I've heard from a phone is - and it hurts to say it so much that I won't - the i ?#"¤%&4.

Walk or drive to work - phone.

Walk in park/mountains or lying on beach - dedicated music player.

Works for me.
[Galaxy S II General] BarryH_GEG:
I have the same headset. You'll see a few posts back I tested background noise for someone. Either listening to music or with the phone idling it was dead silent. I don't know what caused your specific issue. I'm quite satisfied with the sound. It's certainly as good or better than my ex-G2/G2X.
[Galaxy S II General] bendispo:
Wow... I wonder if something is defective with my unit. I'm still definitely hearing background static switching through applications, scrolling through settings, lists, etc. The crackling static initiates for a few seconds and then goes so silent again with repeated scrolling.

I am using high-end IEM's (UE triplefi10's), but it seems like several others of you are too. I don't notice anything when I'm listening to music, though I'm not listening to quiet piano music either... ;-)
[Galaxy S II General] anandyaa98:
not the best placement. also in gt racing the engine noise cuts out randomly
[Galaxy S II General] omersak:
http://www.swedroid.se/rightmark/sgs_ii/samsung_galaxy_s_ii.htm

Some more disappointing numbers, merely confirming what we already know. The optimus 2x wouldn't have been a bad bet at all but for the stereo crosstalk.

And obviously the nexus s is without voodoo sound.
[Galaxy S II General] fallenguru:
Well, neither did I, to be honest. Until Voodoo, that is. Now I'm thinking if great sound in a phone is a possibility it'd better be reality in a €550 flagship. Or in other words: The cat is out of the bag now.
[Galaxy S II General] Gilgehmesh:
I still use my S9 for listening to music. Now if I can get a hold of Fischer Audio DBA-02... try a friend of mine's on my S9... what a great match. I still need to try voodoo to see how it compares to my S9.
[Galaxy S II General] bendispo:
The Korean firmware update schedule has dates from a couple of week ago, yet the post is dated from today. Not sure what to make of that.
[Galaxy S II General] Ayrlupine:
This is entirely off topic, but a 12 year old? I managed to get A in A level Maths, Further Maths and Physics, but it wasn't without work, and a lot of people still fail. And logarithm tables are part of the syllabus...

I do a Maths degree at Durham Uni now, and I still don't think A level maths is 12 year old worthy!

Also, that binary was wrong if it was meant to be 6880800.

Sorry to be so off topic, it really just narks me off when old(er) people say exams are piss easy now. There's a chance they're slightly easier, but I'm sure it's just as likely that more people pass now because of access to the internet, and thus access to better learning resources.
[Galaxy S II General] ph00ny:
How do you like the triplefi10s? i tried out for a week and didn't like it much since i prefer a little warmer sound signature

As for the sound issue, i think i'm beginning to get used to the sound level. I havent gone over volume 10 yet even during my commute via nyc subway
[Galaxy S II General] barneypooch:
@Barryh

Hmm, that's interesting. I'm definititely not imagining things. I wonder if my phone is faulty? Except that wouldn't explain why the noise goes away in Poweramp...

Sent from my GT-I9100 using Tapatal
[Galaxy S II General] B3311:
Sorry, also off-topic.

Ayrlupine, no problem - your opinion is as valid as mine. And thanks for the binary correction - just tried again, should be 11010001111111000100000, correct? Think I doubled something during my 4th glass of Chardonnay last night... (edit - maths wimp googled, is correct:o)

Maybe 12 is an exaggeration, but I'll definitely go for 16. I did Maths, Physics, Chemistry & Biology, also worked bloody hard and wouldn't have got straight As without doing so.

But I still maintain that the A-level exams today are a lot easier than those of 30 years ago. My brother - an ex-physics lecturer at Leeds - puts it in much stronger terms... See if you can find any papers from the late 70s/early 80s and see what you think.

Good luck at Durham - great uni.

Still miss physics (I did medicine, FWIW) - Rutherford was right - all other sciences are stamp-collecting:)
[Galaxy S II General] supercurio:
I'm upgrading to the latest KE7 and will tell you if the audio situation changed or not.

Well, as soon as my battery is full enough for Kies which is very demanding :D
[Galaxy S II General] slitch:
Ke7 seems to improve audio a bit.

Could be mistaken though, went out last night so my hearing isnt 100%.
[Galaxy S II General] Ayrlupine:
I just re-read my post back and it sounded harsher than I meant it to, sorry if I came across as such!

Anyway, thanks for the good luck! I'm finishing my final year on Tuesday haha :3

Back on topic: really hoping there'll be some fixes to the audio quality in the future! I'm very excited to listen to Portishead (and others, of course) in the best possible quality!
[Galaxy S II General] TheUndicider:
I am trying to pick a new phone, I am close to choosing SG2 over HTC Sensation but then I noticed this thread and now it bothers me. How does the sound quality of SG2 compare to iPhone3G which I currently use, and HTC Sensation? Will I even notice the difference if I use cheap headphones like Creative EP 630 for 15euro?
[Galaxy S II General] LondonGemini:
Tbh I found the sound from my 3gs to be a bit better but that's nit to say it was good!

I think with those headphones, you wont really see much difference. And remember that source material is very important. A 128kb mp3 will sound rubbish no matter how good the player and headphones are!
[Galaxy S II General] :
I'm waiting to see what supercurio does with the audio on the SGS2 before I even consider one. I game on my vibrant using headphones and with voodoo sound the audio is AMAZING. Now I'm a little late in this thread but do we have a datasheet for this chip?
[Galaxy S II General] Woodend:
I´m following Supercurio on Twitter. Judging from what he´s tweeting the chances that the SII will ever be a good audio player are near zero.

It´s a shame considering that the other features are really good.

The big question for me now is, which upcoming Samsung mobile uses a decent DAC.
[Galaxy S II General] LondonGemini:
Not to be a git, but I am getting g a bit annoyed by people thinking that there's only a dac that is used to play back music. There are many other parts as has been stated in this thread many times. Ie, imagine you have the world's best cd player but you connect it (via crap cables) to a 20 year old Goodman's amp and to a pair of Argos speakers with Turbo written on them in red. Do you think it will sound any good?
[Galaxy S II General] supercurio:
When the DAC is defective, you can use whatever other component around it, the source signal will always be bad.
[Galaxy S II General] lycan_codex:
I have informed about the issue and pinpointed this thread to gsmarena.com and engadget.com. I encourage everyone to do the same, so that samsung will notice the issue and rectify the design in later models.

Supercurio, do you think all models have this issue or only certain specific ones? although, going by the answers here, all models might have this!
[Galaxy S II General] B3311:
Just been reading your twitter postings supercurio - what a shame (and what the hell were Samsung thinking of...).

A pig with lipstick is still a pig though...

Thanks for your efforts - back to my S9 and/or SGS+Voodo for music, and at least I'll be more motivated to listen to my Italian lessons on my SGS2;)
[Galaxy S II General] LondonGemini:
OK, I understand about rubbish in, rubbish out. I was just a bit annoyed that people think all the issues with the sg2's sound quality is down to the dac. People on this thread seem to get electrical noise which seems to be down to poor shielding. My personal issue is distortion at high volume which, and I may be wrong, is down to poor amplification.

Personally I find it a shame that Samsung messes up the audio on this phone as its almost petfect
[Galaxy S II General] supercurio:
Its to early for that today. (just empty accusations)

But yes it will be welcome once my analysis will be published.
[Galaxy S II General] rayw:
Hi,

I thought you've been a bit hash here..

I am music lover and love to just carry one device that had everything..

I've been using Shire headphones for years now and let me tell you that with SGS + audio booster I can't ask for anything better.. the sound was top quality with every detail and could go louder till the point that you can't handle. But with the SGSII is really bad and very low.. I would be very upset if no one find a solution as this handset is top in the list...

Now, I've been a fan of Sammy for years and they never cut on sound although they leave the phone's sound low to cover themselves but they always leave a gap for people to get things better, this is the reason why I got the SGSII as i believed that it will be similar to the SGS...

Sent from my SGSII GT-I9100
[Galaxy S II General] rayw:
Apologies, meant SHURE Headphones ..

;-)

Sent from my SGSII GT-I9100
[Galaxy S II General] LondonGemini:
My apologies too for being harsh.

Still its a shame that Samsung dropped the ball on the sound of the sg2
[Galaxy S II General] Jeshter2000:
If they don't do anything about this .. I will sell it for sure ... I use it as a Mp3player all the.time !
[Galaxy S II General] Jeshter2000:
Stupid comment!!
[Galaxy S II General] Woodend:
Same with me. Will sell it when something better comes up.
[Galaxy S II General] Miracle1980:
I bought a Sansa Clip+ for 20 euro after tested from a friend of mine. I'll switch the micro-sd from the SGS2 in the Sansa and i'll use this as mp3 reader. It's small, i don't need to plug-in\out the headphones everytime from the phone and there is no phone that will sound good as this Sansa. Even the Cowon Iaudio7 has been beated from the CLIP.

Very High Quality mp3 reader!
[Galaxy S II General] ph00ny:
Is everyone in this thread using quality earphone/headphones?
[Galaxy S II General] blackstar84:
I buy an mp3 player and wait for Galaxy S3 this autumn instead.

[Galaxy S II General] Limpperi:
Is it possible to put 5.1 on when headphones is not attached? i8910 could do this via cfw and after that it souded better than my laptop. it was just simply amazing.

I really hope, that someone would check is this possible on gs2. The only thing i found better on i8910 was the speaker(s) when 5.1 was enabled.
[Galaxy S II General] kradcliffe:
@Supercurio,

I noticed on twitter you said it's possible to boost the volume by 6Db. Is it possible for the user to do this as a temporary fix?

Thank you - Keith
[Galaxy S II General] SBS_:
I saw the sinus wave flac you posted on twitter and I tried it on my SGSII, it didn't play any sound at all on mine (no noise no nothing)... Tried with both the stock music player and moboplayer with 4 different headphones at max volume. Is that what you were getting at in your tweet?

Thought at first it was very high frequency or low volume, so I kinda shocked myself when I played it on my pc :p

edit:

False alarm... The .flac is completely silent if you download it through the browser and try to play it in any player. Works just fine if I start the file directly with Moboplayer on download.
[Galaxy S II General] TheUndicider:
The problem is only with analog audio output and using Bluetooth headphones will avoid the problem completely do I understand that correctly?
[Galaxy S II General] fallenguru:
Until Bluetooth can transfer losslessly compressed audio or at least pass through mp3 without recompressing it using SBC the point is somewhat moot, isn't it?
[Galaxy S II General] -Juff-:
SBC should nowadays be able to transfer with rates that are comparable to 320 kbps mp3.

I ordered my phone this weekend and will definitely give my SE bluetooth adapter a try and compare it to the plugged in audio quality.

I will share my impressions ofc. :)
[Galaxy S II General] fallenguru:
It's still a lossy compression step atop the first, isn't it?
[Galaxy S II General] -Juff-:
You're right, but if your source material is high quality (let's take 320 kbps mp3) you shouldn't really lose so much quality that the output gets completely ****ty.

Ofc all this is theory crafting, but in terms of specs (transfer rate & stuff), bluetooth should be able to transfer hq audio in pretty good quality.

[Galaxy S II General] lynx2k50:
And is this good or bad?
[Galaxy S II General] lycan_codex:
let Supercurio release the complete analysis. from the graphs, IMD + Noise and stereo crosstalk looks little worse than SGS [ and much worse than Voodoo Galaxy ] . But there are not too bad either.

I am only commenting from the graphs. i dont know the whole story. we need to wait for his analysis.
[Galaxy S II General] ke3pup:
Dear Supercurio

i'm looking forward to your analysis and hopefully your voodoo app to fix these sound issues on SGSII. I would say it would be worth$10 once released as i listen to music alot (though i know nothing of all this analysis stuff you're doing :) )
[Galaxy S II General] p3t0r:
Not likely - "I'll finish writing my analysis so this won't be just words but proved facts,

and don't plan to work more on the audio topic for #GalaxySII

" [src:twitter]
[Galaxy S II General] lycan_codex:
How is the music quality? in general. I haven't had the opportunity to play with SGSII, i have ordered one. looks like we have to live with the quality that comes out of the box.
[Galaxy S II General] ke3pup:
that's a pity! The music sounds lower than iphone4 that i came from. i always find myself pressing the Volume Up button thinking its on low but its actually on max!

So Supercurio is doing the analysis just to prove there's something wrong? Hrmm
