Absolutely amazing i love them. I have read all reviews for headphones. And the usual complaints or issues can be fixed easily. You need to turn the volume up to nearly max on your laptop etc Then adjust volume only using the headphone dial. This eliminates any hiss.The hadphone has good volume, good sound, very light and very comfy. Also can walk around the house and use them anywhere due to the good reciever. Only 2 improvements. 1 if you knock them and the battery moves it may cut off sound so jus hav to move the battery to get them working again. Also would be good to have a low battery indicator. Apart from that these headphones are perfect. Oh yeah also this is key make sure you initial charge is 10 hours to reduce battery 'memory effect'
