Mmm... connection, battery backup and sound quality.

Connection- EDR technology. Easy pairing, once u pair, it will connect automatically next time. It is also easy if you want to change and connect to another device.

Battery - Aerage. Can't expect more at this price.

Sound Quality- Major drawback. The bass is too bad and it sounds like old chinese phone speakers if u listen by earphone. But in other sound systems like car sound system, woofer, home theatre etc. it work fine. Overal...
