think Hisoundaudio hit a sweet spot in terms of balancing size and sound
quality. Long battery life, high quality earphones, high end FM tuner, and
an expandable microSD slot makes the AMP3 well worth the low price. The AMP3
is also worth its weight in being a portable amplifier for efficient
headphones. With such a nice sound signature coming out of the AMP3, many
music enthusiasts could overlook the interface flaws and enjoy the clear,
detailed sound coming out of this player.
