The 4 star rating is due to the lack of bass (which doesn't bother me) and the connections between the two speakers

Really nice - loud, good sound, easy Bluetooth connection..

only complaint is the connection for the speakers

The sound was great the only issue I had was at arount 40 feet from the main speeker I start to loose my bluetooth connection and it begins to go in and out

I have walked up to ~ 120 to 150ft away line of sight without loosing connection

Really nice - loud, good sound, easy Bluetooth connection..

if there is anything in the way of line of sight it loses connection
