I have just bought a Samsung Galaxy Ace 2 (running Gingerbread), to replace both my dumbphone and iPod. However, the sound quality is horrendous (washy bass, crackling highs) when I use my Ultimate Ears 700 earphones (there is also a fair bit of background static). This appears to be due to their low impedance. If I plug in my Denon desktop headphones, the phone sounds fine. I also have a splitter with an inline volume control, which if I turn up the phone volume to max but dial the inline control way down, it also sounds fine.
So the issue is poor sound quality when the phone's audio circuitry is being driven at very low levels. Does anyone have ideas how to solve the problem without using a bulky analogue inline volume control? If I can set the volume in software very low, but keep the phone's amplifier gain up high, that might accomplish the same thing (as long as I don't get my eardrums shattered by some other noise that the phone hasn't turned down).
