This was ordered for a caseworker and not for myself. She has to get used to the headset, but she is positive she will like it. It is great for drowning out the sounds.

I wear Senneheiser headphones often, and these feel just like my favorite pair. I'm not a huge headset fan, but I need it for my work. This is comfortable like headphones and from a good brand.
