Months ago, I had bought an almost identical headphones at Pearl, with whom I was quite pleased. That's why I wanted to buy for my daughter also and found him here on Amazon - even a little less expensive and in addition with a storage bag. From the quality and function of both copies are indistinguishable. Of course you can expect from a headset of this size and price range, no hi-fi experience - that would be presumptuous - but for use on the go, the sound quality is always sufficient. The neckband is a bit strange at first, but has over head ironing the advantage of not interfering with headgear. Unfortunately, the strap is not adjustable, which could be a problem well with very small and very large heads. But for me and my daughter it fits without complaint and presses permanently not excessively (in hours of listener presses ANY headphones sometime). The Paring with any Bluetooth device works perfectly. The most important functions can be controlled with buttons on the right headphone (soft and loud, song forward, backwards song, call answer), but it takes a while until you have the position of the keys memorized. Here, perhaps, appropriate sensing brands would be appropriate. On the positive battery time surprised, he also keeps in daily operation lasting several hours through several days. Charged is on a mini-USB jack with any USB charger. All in all for the price a decent headset without unnecessary frills.
