The sound is just cream.
Comparing as 1: 1, and not as some big here sound systems with small speakers, you can logically only be 5-star. Certainly missing the device some, but for me negligible functions as a speakerphone for your mobile phone and such gimmicks, in its core task of playing audio titles convinced of Bose in every aspect.
That you thus produce a beautiful product :) Thanks Bose
