Due to the reviews saying this cranks out volume with clear sound, I bought one. It does sound good, but volume is limited. It's not as loud as the same size (old) Tango I have. Then again, the Tango has no internal battery. Yet, I don't need that anyway. The treble in this DOSS needed boosted a bit by my device eq. It has a nice sound, just not as loud as I would like. I would say this is probably the best quality you're going to get at this price point for sure.
