At this price these are extremely good value for money. Excellent reproduction. Very light weight and soft padded earpieces make them very comfortable to wear even after 4 hours! On one occasion I stood up and walked away from the computer yanking the plug out of the socket because I'd forgotten I was wearing them!
I also have a very expensive set of headphones but they are so heavy and grip the ears so tightly I cannot use them for more than an hour. Needless to say they are now replaced by the 330PC headset!
Highly recommended.

Good points Light. Comfortable to wear. Easily adjustable. Stable on head, do not fall off or move in use. Excellent sound quality. Unobtrisive.

Bad points NONE
