Sound quality: Edifier's E30 Spinnaker Bluetooth speaker system has very good overall sound quality. Bass has good impact but can crowd the midrange and lacks some definition; it can be boomy and loose with some program material, and deep bass is lacking. Midrange is smooth and even, and treble is extended though a bit uneven and lacking in air and fine detail, so the overall sound is slightly dark. There's good room ambience recovery in the midrange. This model's sound quality was pretty similar whether it was connected to the player using either Bluetooth or the wired analog input. It can provide satisfying volume in a medium-sized room.
Ease of use: We found the system's ease of use to be good overall. The Bluetooth pairing was very easy, but making some of the required physical connections (power cord, speaker output) was difficult due to tight clearances on the bottom of one of the speakers. (Also, the speakers aren't marked "left" or "right"; the right speaker is the one where the connections are made.) There are no controls on the speakers themselves but source selection is automatic, so when you pair the speakers to a Bluetooth device it switches into a Bluetooth mode. It will switch back to wired operation when you unpair a device. The controls on the included unconventional remote control aren't marked, but the most commonly used functions are easy to use once you determine what they are.
