Recently acquired these for my 40th (:-() birthday and very pleased!
Very comfortable (and adjustable) with plenty of padding on the ears.
The sound quality is excellent - particularly on vocals and bass guitar.
I'm very into Symphonic/Progressive Metal as well as Classical so good sound is a MUST!
The headphones are completeley wireless and powered by rechargeable batteries (present in the box) and there's a small wireless transmitter with a DC adaptor that stays connected to the mains. You simply use the cable to attach the transmitter to your audio source; DVD, HiFi etc and the signal is sent to the headset - really simple. You also charge the headphones, via a lead, off the transmitter unit. You get a Jack adaptor so the transmitter cable will fit every socket. Don't worry about leaving the DC adaptor connected to the mains - It only powers up (red light indicator) when it's connected to a stereo or DVD player etc that is switched ON. When you turn the audio/video appliance OFF, after a minute or so, the red light fades and the transmitter powers off - so you don't need to pull the plug out when not in use. The headphones have their own on/off button, and a volume setting that works in conjunction with the audio source.
The wireless range is excellent - even when leaving the bedroom, the sound was excellent all around the house. I even sat outside on the patio the other night at the back of the house and got a reasonable reception! And bear in mind, the stereo connected to the wireless transmitter was in a bedroom at the FRONT of the house! Yes, there was a reduced quality BUT it was still good enough to allow me the joy of the night air!
Very happy with them - Excellent for good quality music.....
