I was shocked at the audio quality from this Sony blue tooth speaker. I'm an audiophile and pickier than most when it comes to wanting sound that is balanced while still sounding detailed enough without being bright. I actually prefer the sound without the bass boost button used which seems to be in the minority from other reviews including pro ones. I feel the bass emphasis does add bass and makes the sound first seem to be a lot better since the sound level dramatically increases but once I balanced the volume levels, I found to prefer the sound quality without the bass boost since it was more detailed, balanced and still provided adequate bass. The one quality I was disappointed in is that the treble seemed closed in when the speaker was brand new so critical that you play music through this speaker for a good 72 hours at least with the volume up enough to adequately break in the drivers. Once this occurs, the treble opens up. Still the treble doesn't provide the air you would expect from an audiophile speaker but that would be crazy to expect that at this price point. This speaker is perfect for its size and portability along with the great sound quality. The weight of this small speaker is surprising which is a very good sign since the weight shows the quality of the drivers used. I tried using some small Bose blue tooth speaker last year from a coworker but wasn't impressed at all since the bass was flabby with no that much detail with the sound quality not balanced at all. My ears immediately go to sound not balanced that many may think a speaker has great bass or vocals only for me to tire of listening to music. Bottom line, I think one would be hard pressed to find a better speaker in this price range but again, I highly recommend to break the speaker in as much as possible, say a full week, before deciding to return for any reason.
