The sound reproduction is really impressive for such small speakers. During movies and sports, they added a fun, new dimension to the audio experience. For some programs, I noticed some irregular use of the rear channels. Voice tracks during a few programs would be present in the surrounds on and off during the same dialog scenes. This is not Bose's fault, nor was it actually all that distracting. It was just something I noticed. The Bose Music app allows you to adjust the volume of the rear channels so you can achieve your best surround experience. Or you can simply turn them off in the app.
