Guys, I'm getting myself a pair of Klipsch S4 (note: not S4i) and hope they pair well with my SGS3.

Do I need to burn-in the headphones? Does anyone have an advice about burn-in (method)?

I looked up the i-net and found amongst other thing this burn-in guide:

**********

How to burn-in put some lossless in your phone or any music device and play with the 30 % volume for 5 hours , then 30% volume at 10 hours , then 40 % 10hours , 50% 10 hours , then 60% for 10 hours , repeat the 60% process until you reach 150 hours . Give gap of 1 hour atleast between each period .

**********

Or can I just download the burn-in app from the market and let it play for some hours?
[Galaxy S III General] ph00ny:
You beat me to this

There was another post that talked about akg earlier, some akg sets are notorious for needing a beefy amp

I had the akg 701 and i just couldn't use them to their fullest outside of home (proper amp)
[Galaxy S III General] ph00ny:
Oddly enough i didn't have the interference noises with the s2 or the note but experienced it in 7.7

I also have voodoo louder running on the note and s2
[Galaxy S III General] elfary:
That spurious noise appears when listening thru Google Play or with any music player?
[Galaxy S III General] gaui:
When I record a video and play it afterwards in my computer, the sound is only right side?

Any else experiencing this?:confused:
[Galaxy S III General] Kendoji:
Or you could just start listening to music and enjoy your headphones. :) I've never believed in these convoluted burn-in methods, life is too short.
[Galaxy S III General] kurama.k:
I have the klipsch image s4 and they sound great with my galaxy s3, good clear sound with great bass :) I don't think these type of in earphones need to burn in, I just think the big headphones need to burn in before getting the best out of them :)
[Galaxy S III General] Cyb3rGlitch:
Burn in is a load of crap. Just use and enjoy them.
[Galaxy S III General] teatime0315:
I don't agree but ymmv of course. Of all the headphones/earphones i've bought "burning in" definitely made them better.
[Galaxy S III General] gavinfabl:
Burn in will make a difference but you need to keep them connected for a week playing non stop to accelerate process. Normally connect them to another device I have and stick in drawer. A week later it's all good stuff.
[Galaxy S III General] tolis626:
Well,the whole "burning in" story sounds to me like when lithium ion batteries first started appearing in mobile gadgets.Sales reps would tell you that you needed to leave the batteries plugged in for like 20 hours straight to get their full capacity,like Ni/Cd batteries needed.You can start using them without burn-in and you'll just notice their sound getting better day after day,provided you hear music enough time on a daily basis.At least that's my opinion on the matter. :)
[Galaxy S III General] gavinfabl:
If youre feeling brave and very strong about this view, why not start a thread at www.head-fi.org :)
[Galaxy S III General] teatime0315:
lol'ed. yep head.fi will sort things out
[Galaxy S III General] Cyb3rGlitch:
Head-Fi have a reputation in the audiophile crowd for being full of self-proclaimed experts who have no idea what they're talking about.
[Galaxy S III General] gavinfabl:
Personally the amount of info available is astonishing, what you do with it is your choice. Some people do get carried away. But it is their hobby and passion.
[Galaxy S III General] NA 521":
Someone on an audio site tested break in on a set of Dali Megalines. He measured the frequency response of the speakers before and after break in and saw increased low frequency output after. That pretty much proves it for me.
[Galaxy S III General] burner07:
any news from supercurio? sgs1 had a great sound after voodoo , sgs2 was mediocre and gnex had exelent sound just like iphone 4s (current phone very boring FFFUUU) i hope sgs3 will sound like 4s and gnex

what do you guys think? how stock volume and quality , i have a pair o skullcandy titan and phillips... 4s sounds great

thx
[Galaxy S III General] NZtechfreak:
Interesting, I guess I'm not getting this because I'm using USB audio instead.
[Galaxy S III General] limeaid:
Now this is an opinion I trust
[Galaxy S III General] tolis626:
I suppose you imply I'm wrong and the guys there will flame the **** out of me,eh? :p

Well,I'm not gonna defend what I said if someone believes I'm wrong.I'm no expert or dedicated audiophile,I just enjoy and appreciate good sound,so my opinion isn't always the right one.It's just my opinion that you buy a product to use it,not leave it alone in order for it to become more "mature".My point is,use the damn thing,we've already had enough theory thrown at us. :)
[Galaxy S III General] Devtodi:
But they definitely have opinions.
[Galaxy S III General] NA 521":
The fact that we can just plug this phone into a DAC is freaking awesome. I might have to break down and get something like a Benchmark USB DAC1 now. I have a Channel Islands DAC that's S/PDIF, but USB is more attractive.

Has anyone tried playing 24/48 or 24/96 FLAC files? I don't have anything in 24/192 (yet).

Crackling sound visualized

I see quite many people suffering from that 'crackling' sound that comes randomly whenever the music is playing, and I also noticed it. Since this is a bit irritating I wrote a short analysis of the playback sound of SGS3. I played a test signal which plays only 1kHz of sine wave for 10 minutes, and waited until that crackling sound happens again.

First, this is a part of the 1kHz signal file that was played through my SGS3, which seems to be OK, but take a look at the next image I attached.

Now this throws us a hint that signal is significantly distorted at 00:01.346, but this doesn't actually show everything about noise that's happening during the playback. That's why we need to take a look at the spectrum of the output sound.

I got you noise!

[YOUTUBE]http://youtu.be/ObXT-08CYZg[/YOUTUBE]

Damn Youtube. You just can visit here for the video. http://youtu.be/ObXT-08CYZg

Actually this noise lasts really short so it was quite hard for me to catch that.

In the signal file I played, the actual contortion starts at 00:01.26084 and ends at around 00:01.34676. Of course these figures are based upon that GoldWave spectrum analysis; you cannot tell exactly when that noise happened because it just zips away.

For those who want to take a closer look yourself, watch this video please, or download the file I attached here. You'll see the real body of the crackling noise.

Hope this is just a bug in the firmware, especially the wrong wolfson dac driver settings from Samsung 'cause I see that rise in the frequencies except for 1kHz is rather consistent.

+

Anybody know how to report this issue to Samsung? I tried to report this to Samsung Korea but they redirected me to nowhere.

++

Seems to be related with power management.
[Galaxy S III General] g4rvd4:
Just got my S3 yesterday and tried out my new Sennheiser PXC 310 BT with it.

What can I say .. wireless apt-x is bliss! My files are mostly mp3s at 320 kbps and the quality is superb on the S3 coming from a Desire.
[Galaxy S III General] chong81:
Great analysis studiominal!

I flashed the latest LF2 firmware, and this crackling is still present. :(
[Galaxy S III General] studiominal:
I'm experiencing exactly the same too even after the LF2 firmware.

I hope it's all messed up with Sammy's audio driver, and it's not fixed in the LF2 yet. Again, I believe supercurio will be here to save us :D
[Galaxy S III General] frifox:
Anybody tested S3's low volume performance? I usually listen to music at the low volume (lowest android volume and then lower it more with player's internal volume control) before passing out at night and my SGS2 would actually cut out during quieter parts of the song. Does S3 do the same?
[Galaxy S III General] chong81:
I've noticed that this crackling problem does not happen in these 2 situations:

Phone is plugged to PC via USB cable

The S3's AMOLED screen is turned on

I guess this crackling noise is power management related. I'll try screwing around with the clock speeds if it's possible with the stock kernel.
[Galaxy S III General] studiominal:
Voodoo sound will make fine volume tuning possible as it did on Galaxy S. I promise it won't disappoint you :) But the problem is the crackling sound that happens randomly. Fortunately I found that the noise is dependent on the volume of the output sound, which means it is likely a software(driver) problem, not a hardware problem. We need supercurio here now hehe

---------- Post added at 05:29 PM ---------- Previous post was at 05:25 PM ----------

Thanks. I'll check this out.

---------- Post added at 06:14 PM ---------- Previous post was at 05:29 PM ----------

I just tested the two cases that chong81 mentioned. Each file was recorded for 10 minutes at the same output level using the same 1kHz sine wave file, so I listened to that dreary tone for 20 minutes. And I'm relieved to report that the crackling sound was gone. Worth listening to it :D

It really seems to have to do with the power management settings. I recommend anybody here to listen to music on SGS3 with its screen turned off, and without USB connection to PC.
[Galaxy S III General] NeoCream:
I finally received my Klipsch S4 Headphones... and they are really good (compared to stock headphones).

I startet to let them burn-in for the next ~50hrs... I wonder if that really changes the quality of the headphone's output.

Anyway, you guys should try out the Neutron Audio Player:

https://play.google.com/store/apps/details?id=com.neutroncode.mp&feature=search_result

It's a great audio player with lots of music tuning (exceptional EQ!). It has a native 32bit audio engine and (unfortunately) a horrible GUI... but the quality of the music gets definitely raised!

I did not encounter any cracking currently... but I have to test a bit more... the low volume level of the SGS3 is fine (I usually listen music with the lowest volume-bar... but I wish SGS3 would offer more volume steps ...)
[Galaxy S III General] hefonthefjords:
Speaker burn in is pure snake oil.

I have been working in professional audio for a decade and never seen any evidence to support any difference in sound reproduction between hour 1 and hour 1000.

A speaker will sound the same the day it dies as the day it's born. Your capacitors in your amplifier and crossovers will dry out sooner than your speakers will change their sound.
[Galaxy S III General] celsior360:
That's pretty stupid if I wanna listen to music and browse twitter or FB at the same time, then I must compromise with this flaw ?
[Galaxy S III General] studiominal:
No. You got me wrong. (Maybe I should've said 'try' instead of 'recommend' up there)

That's the way you could hear the crackling noise, not a workaround to avoid the noise. In either case or both, I couldnt hear the noise, so I would like to let people who say they dont have noise on their phone have a chance to face the real problem and potentially lead to Samsung's hotfix regarding this issue.

In short, multitasking is unlikely to cause that noise because the screen is turned on. However if you're out listening to music on your SGS3 with its screen off, that's the problem.
[Galaxy S III General] Erahgon:
In this case, for anyone using PowerAMP or a player with prioritization capabilities and the ability to adjust the buffer size: as a workaround, try setting the priority to an above normal setting and the buffer size to a larger setting.

If this problem has got anything to do with either the buffer or the LMK (due to the power management problems) it should sort it out.

Try and report (preferably one fix at a time).
[Galaxy S III General] studiominal:
I'm currently on it, and let me report the results in about 10 minutes :)
[Galaxy S III General] celsior360:
Wait for your good news as I'm considering switching to S3.
[Galaxy S III General] brins0:
I've forced the screen to stay turned on and listened to music for a while, and I don't hear any crackling of any kind. I'm gonna go with your thoughts here, and say it's power management related. It might be worth watching the CPU fequency when the spikes happen, as it could be the clocking/voltage change when changing frequencies that's causing the crackling, I've had this on some of my older devices.
[Galaxy S III General] studiominal:
It failed. Seems to be more complicated. However, the fortunate thing is that it may not be a hardware flaw, but a buggy configuration implemented somewhere.

And one more interesting thing is that supercurio tunes FLL clocks of the audio codec he tweaks in Voodoo sound, so in my opinion he'll have some ideas on this issue. Just a guess..

---------- Post added at 12:32 AM ---------- Previous post was at 12:09 AM ----------

I wish somebody here reported this issue to Samsung engineers in your region where you bought your GT-i9300. Since I'm using my SGS3 in S.Korea which I purchased in France, I can't hear any answer to this issue from Samsung Korea. All they say is that they cannot help me out because my device is not for sale in Korea. Damn!
[Galaxy S III General] tenjakid:
thanks God! finally people noticed the static noise! i posted in the fault thread and no one replied! anyway, guys, lets dig out the main cause of this. i got my phone in singapore. M1 as the mobile supplier.

ive been using playerpro since sgs1,and yes,there's buffer setting from low to high. I've tried them all,but to no avail. i notice too that the static noise only pop out when you listen to music when the phone is sleeping.
[Galaxy S III General] studiominal:
Glad that I'm not holding a hardware-flawed phone. It's gotta be something that engineers have to dig down the kernel to come up with the total solution I guess. Don't know how the audio driver from supercurio works on this condition(supercurio actually rewrites an audio codec driver - GENIUS!), but I think this is quite a serious issue that someone has to report to Samsung.

And I guess it's a random pop noise, not static :)

Anyway the SQ itself is reasonably good even without Voodoo sound, which means the audio codec still has capabilities & potential.
[Galaxy S III General] elfary:
Years pass by and it seems that Android/Samsung will never get right a headphone out.

It's terrible that in 2012 they are as far as they are from iPhones in the sound department.

Static noise and pops seems to be interwoven with the Android OS.

The idea of having 128GB of storage for music on a cellphone looks great...if you can ensure that sound quality is gonna be high. Otherwise it means nothing (for me)
[Galaxy S III General] Kendoji:
Hmm I haven't noticed the pops at all, will listen for them.
[Galaxy S III General] kruso:
I can hear it with screen off with my klipsch s4. The noise is not present with my Philips headphones.
[Galaxy S III General] Erahgon:
Shucks. It may be more complicated than just a buffer fault or a prioritiztion fault then (that's as far as my knowledge extends lol).

Could you give another shot with a few more tests:

1) DVC (Direct Volume Control) On and off?

2) "Keep in memory" on and off?

3) Priority and buffer all the way up. See if it occurs at the usual time or a bit later.

The 3rd one is with regards to an experience I had with my PreSonus and my Windows laptop, where, due to output buffer problems there was dropouts in sound (it would literally grind to a halt and start back up again after a second). Increasing the output buffer resolver the problem.

It sucks that they don't even consider the problem if you bought the device somewhere and use it elsewhere... it's a terrible thing for a company to do. Unacceptable!

I would do these tests myself (with a little help of course), but I don't have the i9300 nor do I know anyone willing to part with it for a few tests (they get scared for some reason when I say "tests"... odd... :p )!
[Galaxy S III General] krypton_the_slayer:
Can someone here with root access give me a screenshot of whats in your /dev/snd/ folder, an output of dmesg just after you plug in a DAC (the part where usb audio devic is detected). Trying to get usb audio support for the galaxy note. I have other requests too if anyone would like to help. Thanks

Audio Playback

Kind of off topic but I've tried almost every single player out there on my GSIII. The new JetAudio is excellent but I'm sticking to player pro. The audio output is excellent on the JetAudio. The stock earphones are pretty good too. I was really wishing Samsung bring out SRS WOW on this on a better Audio chip but aw well.

Plus, I've got a wallpaper blog on

[Galaxy S III General] goody_23:
hi guys thank god we have many more ppl that have noticed this crackling sound i noticed it the first day i bought my phone and used it... i didnt know it only happens with the screen off i tested it and you guys are right.... is there anyway we can report it to samsung engineers the audio quality is good but the damn crackling sound is annoying!! we need to report this pronto !!
[Galaxy S III General] studiominal:
Those workarounds still cause the random pop noise and have nothing to do with how often it happens. I think it's a kernel-level problem where hibernation (or whatever) mode affects the sound output. What is nasty is that linux commands wouldn't help because they'll require USB connection, and then the noise will be gone! Even when running the command right on the phone, the screen has to be turned off and record the CPU frequency in surveillance in order to capture that noise. Tough one :o

At least the clear thing is that it's got to do with the power management, and it's fixable if we strongly appeal to Samsung about the issue.

---------- Post added at 09:44 AM ---------- Previous post was at 09:28 AM ----------

I agree with you. Sound is great, but the crackling noise is awful.

I think somebody in UK may as well report this issue to Samsung. I sent another email to Samsung Korea and am waiting for the reply.
[Galaxy S III General] frifox:
SSH into the phone through WiFi. That's what I did that whey trying to debug issues on my S2. Phone goes to sleep and SSH is still running.

In the worst case scenario, just wait till the POP noise comes on and then run a "bugreport" for a complete kernel/system/etc log dump.
[Galaxy S III General] studiominal:
Thanks! But I'm not a linux expert so we'll need another person. I mean, supercurio is the perfect person here but he seems to be busy nowadays. I already noticed him of this issue before.

However, comparing how CPU works in these three conditions would draw a hint towards the solution.

1. Music playing with the screen off

2. Music playing with the screen on

3. Music playing with the USB connected to PC

Personally I don't think some sort of 'jitter' generated from the application processor directly hit the audio codec, but it's a result of abnormal configuration. That noise is too clean to be thought that it was affected by jitter from the electric circuit which normally has irregular patterns. As you might've seen from the page 33, frequencies jump up to the same level and then drop rapidly.

I just rooted my phone and installed SSHDroid to check it out myself. Running some commands like 'dumpsys power' or 'cat /proc/cpuinfo', and I noticed that core utilization changes when I turn the screen off.

SCREEN OFF

/mnt/sdcard # cat /proc/cpuinfo

I noticed that regardless of USB connection status, BogoMIPS for core 0 stayed always at 1592.52, so this hasn't revealed the culprit yet. Random pop noise still present when the screen is turned off AND usb disconnected. This means CPU frequency has nothing to do with the noise.
[Galaxy S III General] LoneReaction:
I got my set from Singapore, and I notice the 'crackling' sound as well. Using JH16 earphones. It is driving me crazy. At first I thought my mp3 files were corrupt, but when I replay the part of the music where the crackling appeared, I always fail to reproduce it.
[Galaxy S III General] studiominal:
This is why you fail to reproduce the noise - navigating to the point where the noise appeared requires the screen to be turned on. And the noise occurs randomly, but quite often.
[Galaxy S III General] stepinmyworld:
All yall people with galaxy s 3s and not many of you placed examples on YouTube pertaining to speaker quality, videos audio quality test etc.. just a hope bunch of tech jibberish lol ... I'm waiting for the 21st so I can get mine.. I'll be sure to give many examples

SGS3 - FiiO E17 Full-Speed / High-Speed switching issue?

http://www.gfec.com.tw/TE7022L

http://www.ti.com/lit/ds/symlink/pcm2706.pdf

SGS3 USB driver issue?: some parameters are not well-adjusted?

"The host controller directs traffic flow to devices, so no USB device can transfer any data on the bus without an explicit request from the host controller. In USB 2.0, the host controller polls the bus for traffic, usually in a round-robin fashion. The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port."

http://en.wikipedia.org/wiki/Universal_Serial_Bus

Powered High-Speed USB 2.0 hub workaround?

"High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. When a high-speed USB 2.0 hub is plugged into a high-speed USB host or hub, it will operate in high-speed mode. The USB hub will then either use one transaction translator per hub to create a full/low-speed bus that is routed to all full and low speed devices on the hub, or will use one transaction translator per port to create an isolated full/low-speed bus per port on the hub."
[Galaxy S III General] roylee01:
I hope it´s software related but this afternoon while on the train I heard some cracking noices while listening to MP3´s. like someone putts the needle on the LP or a very old music plate. (late 50´s) I think it's a fault in the buffer-size or something.
[Galaxy S III General] Erahgon:
Not buffer size, it's been tested, but it could be buffer implementation. Something to do with power management too.

The good news is that Wolfson Microelectronics is helping Supercurio in terms of information - he tweeted. Hope he can delve into this and get it up and working better than ever!
[Galaxy S III General] studiominal:
Supercurio's voodoo sound might fix this because he actually tunes the really low level of the sound codec like FLL clocks. However, for those who use their phone as it is, this is a serious problem. Coming only when the screen is turned off and usb is disconnected, the noise totally screws up the listening experience. Samsung engineers definitely have to solve this.
[Galaxy S III General] NeoCream:
You were right... I let my headphone burn-in and I think I did not experience any real sound-enhancing.... but nevertheless... the klipsch s4 headset sure sound well with my SGS3 :D:D:D
[Galaxy S III General] pruhster:
Just received a USB host cable and I'm happy to confirm:

GS3 works with my Allen&Heath ZED 14 mixer via USB OTG. I assume most standard compliant USB enabled mixers should work too.
