Iphone 4g: iOS5 Bad sound quality.

I don't have a suggestion for you, I just thought I'd chime in on this problem too.

I am also hearing something weird. I normally use the music app through the dock connector in my car, and in this case I have the EQ "Off". The lower-end seems a bit distorted, enough so that its made me start messing around with the EQ in my car. I've had the same settings in my car for 3-4 years with no issues, so this makes me think there is something off about the new "Music" app.

A quick search around the web shows a lot of people complaining about this. Apple, help!

Guys this fixed the problem for me, first of all the problem is in the iTune library vs the iPhone, or better yet in the way the new iPhone softaware works with the iTune music library.

1) Open itune and click on music

2) Highlight all your songs

3) Open the information window (command i) and select option

4) In volume adjustment the volume bar will be set on "none" unless you have all your songs

set at a different level, in any case move the bar anywhere "plus" or "minus", close the window allow iTune to set all your songs to the new setting, repeat the process and bring it the bar back to "none",

again close the window, allow iTune to set all our songs to none this might take a while depending

on how many songs you have

5) Last plug your iPhone in your computer and when it shows up in iTune click the iPhone then select music and finally sync, all your songs on your iPhone will be sync to the iTune music library new setting and the problem will be permanently gone....

Thanks gianni! This worked for me on some test songs that were blowing out the bass. The offending songs were set to 100%, but I don't remember doing that. (glitch?) I'm going to do the procedure to my entire library now.
