Well one of my latest toys is the Logitech G35 surround sound headset.
This device is second to none in my books and has amazing sound quality. If you are looking for something to wear all day long and not even feel them on your head then these are the headphones for you. I also must comment on how warm they keep your ears as well as the great mic they have on it.
The voice morphing is fun to play with but unless you are planning on kidnapping someone and holding them for ransom then it is just a gimmick.
Only con is that the ear pads are not changeable so when they wear-out make sure you have a needle and thread on hand to repair them.
