    I also went by the AT&T store last night to test out a Focus S using my wired headset. Audio quality was excellent, actually had more bass and a fuller sound than either my Zune HD and my Focus rev. 1.3. Also changed tracks with 30 second zune clips streamed over 3G+. No popping whatsover. May be that a batch of phones has an issue. If it's bad enough, make sure to take it back to AT&T within the first 30 days and get a replacement unit.
    Nope. No issues at all with the Titan connected to the same stereo with the same jack.
    Noticed no issues on the HTC trophy either. Also, was a lot LOT higher gain. About 1/3 louder.

    Well, I verified via repeated testing that this phone has an issue with pop noises only when connected to an amplified system. In other words, connected to powered speakers, car stereo, etc. I used three different sets of headphones, and no popping occurred. It didn't matter which powered source I connected, it always popped in those instances.

    I returned the phone because of this issue. Samsung does not have a great track record of fixing issues with devices they have already released.

    I've read that using a bluetooth headset can negate the popping noise. Does anyone know how using a bluetooth headset would affect battery life on the phone (with having bluetooth turned on all the time)? I don't mind charging during the day if needed, but I've seen the posts here in the forum regarding the slow charge issues which makes me a bit concerned.

    I just got my Focus S last week and haven't noticed any popping/crackling or audio issues. I've used the headphones that came with it and the volume and pause controls work just fine. I've used Zune and Slacker for music. I haven't tried it connected to my wife's car yet. My car doesn't have an audio jack or bluetooth connection.

    Maybe it's a quality issue that they have fixed on the newer phones.

    I was getting the same popping noise listening through the auxilary audio port in my car, then the issue seemed to disappear.

    I rebooted my phone today and the popping returned.

    I have a theory on this, haven't tried yet.

    Focus S has problems with the earbuds controls, it's virtually impossible to jump forward (2 clicks) or back (3 clicks), it's not reliable to pause/resume either. All these signals are transmitted through the last 2 contact rings on the TRRS connector, I think those 2 rings of the jack on Focus S are problematic.

    Meanwhile, the popping noise only happens on AUX port (TRS) but not on earbuds/headphones (TRRS). I'm guessing, the noise might be caused by the last 2 rings when AUX connector is actually contacting 2 rings of the jack. Remember those 4 conduct to 3 conduct adapters (like this one)? I thought they were useless since TRS connector usually are fine in TRRS jacks, but this time it MIGHT prevent the popping sound if I'm right on this.

    It doesn't help, I bought one of these cables cause it was driving me nuts and it does the exact same thing.
