At first test, can't really tell a difference besides more bass and better highs through the SE530's i use.
Question is... will it sound better after burning it it? This amp need burning in?
P.S. it does not have a mic function and cannot use earphone to listen to calls















Not nice at all. Quickly learned not to have headphones on when starting, or to start playback from the amp's play button. Luckily I'm not using earbuds...
