I've owned these headphones for about a year now. They're comfortable, convenient and the quality is not bad when compared to other wireless devices. The problem though is that wireless devices all lack in quality compared to wired headphones and out such a high price, I am not sure I can recommend purchasing these headphones unless you absolutely need the convenience of wireless. The wireless, like on any wireless devices, can cause a humming noise when the source audio isn't loud enough and often there is no way to increase the source audio. Also some short sounds won't play entirely, a 'ding' alert noise will only play a portion of it due to the delay in wireless.
