I bought the Ultimate Ears boom about 4 months ago. Previously I have some looked and tried. The sound is really great. Clear sound and for this size of a super bass. The battery lasts really long (9h least, longer I have not yet heard the piece) Coupling with Iphone / Z3 Sony / Samsung S4 / Macbook Pro 13 'works super fast. I look at the time even my movies on my laptop, because the sound of the Boom Box is better, like my TV device (but that is more to my TV) One must not expect him to replace a home theater system. But for the Road (pool / sports field / picnic) it is 1A and home, it replaces the PC speaker (no more cable clutter). I'm really excited. Half a star I would deduct for the price. 120 to 150 were perfectly ok. But for the property valuation, there is clearly the 5 star.
