Hi everybody !
Personally, I discovered the HD900 headphones made in china. I really love this device since the sound is really clear, the high, medium and bass frequencies really well balanced. The device is bluetooth and allows you to listen to the music wireless from your Ipod or mp3 reader, and to receive phone calls from your smartphone. It is light, confortable and includes a memory card slot up to 16GB.
Frankly, for less than 50 us dollars here, Ive been offered an 8GB memory card.
here are the specifications :

Operation range in standby : up to 200 heures
Lithium rechargeable battery : 300mah
