If your phone / device you will be playing music from has an equalizer, the sound can be adjusted for better indoor audio quality.

You can turn it up pretty loud and the sound quality was clean

The bass is pretty deep with good control and sound quality

I have tried a lot of bluetooth speakers, Sony SRS55, SoundBlaster Roar (in dual stereo configuration with 2 speakers connected), and the Klipsch KMC3, and this is BY FAR the best sounding, with the best bass, best sound reproduction, and quality

However, if you want something with good sound quality and portability, I highly recommend the Bose Soundlink Mini II.

The One is significantly more powerful than even the 2 SoundBlaster Roars, and has much much better sound quality

Excellent sound quality, warmer, louder and punchier than my Audioengine A2s
