Being a Sound mixer I am very picky when I listen to music and often when traveling I my Remote Audio Speak Easy Speaker. However I recently discovered the X Mini II Speaker a few fellow sound mixers had raved about them so I decided to order one. Under $30.00 from Amazon and WOW for the size it is great and lasts about 11 hours on one charge it charges via USB which is great as I can listen to it and charge it at the same time. The bass response and volume level is excellant. I like it so much I am going to order a 2nd one to leave on my sound cart. You should check it out
