According to GSMarena the RAZR has pretty good SQ - http://www.gsmarena.com/motorola_razr_xt910-review-683p5.php
We were left really puzzled by the Motorola RAZR XT910 performance in our audio quality test. Until the very last reading it was a strong contender for turning out the best musicphone ever. And then came the headphones-on stereo crosstalk.
Do you guys think this is on a software level? Also does MIUI support motorolas?
I have the original SGS and the SGS2 is just disappointing from the audio perspective. :/
