Tried a few products like sony xb10, Boat 200, and GO 2. I wanted to use this the speaker for speakerphone also. This is best one in this class. xb10 has a better sound quality no doubt but has a terrible mic with lots of noise etc. GO 2 killed it. However battery performance is a challenge for it, only gives around 4 hours instead of 16 (sony). If you want to get both the features go for it. If only sound is your concern choose sony. It also hanged once but survived it by keep pressing the bluetooth and plus button for few sec. I would have chosen blue, but that seems not available here. Boat 200 comes last in comparison and has fluctuating sound through mic.
