Preliminary said a speaker is only as good as its audio source. I use the Denon audio player with built Equailizer. Thus I have the speaker 2 to trigger the possibility go perfectly. One should not feed them too much Bass it sounds too intrusive, is avoided, the bass sounds soft and subtle. This is my favorite. The sound is very good, better than Bose SoundLink. I'm excited. The connection to the HTC One X and Samsung were 2 is simple. Battery life is decent. After about 7 hours, I have to go back 2 speakers connected to the socket. What I really like is the excellent workmanship. Brushed aluminum, massive, beautiful and the LED indicators are located above at the buttons that do not dazzle at night in the bedroom. Such LEDs can in fact be quite bright. I've also used the built-in speakerphone. It works well. The called party just told me that it sounds to him as if it resonates. But is normal. I can not oblige others who go 2 speaker is too quiet. I can make the speaker so loud that I do not understand my own words. The performance is really sufficient.
Conclusion: + Very good sound + Excellent workmanship + Good features + Oh, he looks chic also :-) + Value for money very good + The speaker 2 go is really fun
Otherwise, a remote control would be good, but is not necessarily, since I all over operator Smartone or tablet.
