Cons: no way to adjust, it fits or it doesn't. For me, it doesn't. Terrible raspy audio, bulky design so it's not portable, and I could have bought a cheapo for better. In fact, I got a free one with a digital camera I just bought, love it a lot more.
Summary: The microphone is not very sensitive, so you will have to crank everything up to max settings in windows, and in the software you are using, and also talk very loud.
Pros: It's cheap, long cord, and it looks decent.
Cons: The earpiece can be very painful. It uses a very thick, hard rubber that is not very flexible. It is not a minor irritation like some other headsets have from hours of use, these hurt right from the beginning.
Summary: Despite reading good reviews about this product I had to return it as I couldn't get it to fit or stay on my ear. I thought this type of headset would be good for me as I have a small head and the normal headsets tend to fall down below my ears. The piece that fits over the ear is flexible but cannot be bent to shape so is no good for smaller people. It fitted my on husband's ear fine but no matter what I tried it would not stay on.
Summary: Coté technique, rien à redire, la qualité est là. Mais le confort ... A mettre avec les 2 mains, Pas très agréable au niveau de l'oreille, la commande (mute & volume) est trop lourd ce qui fait chuter le casque (sauf si vous l'attachez sur vous a chaque fois) Le câble doit faire 1m50, relié à la façade de l'UC que faire du reste .... Je regrette mon achat.
