The sound quality isnt up there with the $100 units of course, but it is fine for vocal range. Considering the Firefly mousepad next. This means you can?t connect more than one to the same computer, the computer simply can?t differentiate between them. They appeared to be very comfortable! She is almost 4. Overall it is a very well made and sturdy product. It feels mostly soft and lightweight. Second the locks I received were not keyed alike and the key supplied only worked on two of four. I was impressed with every aspect from opening to wearing. The sound quality is pretty clear, during calls people reported hearing me a little bit distant, but heard me well (wouldnt know how they perform on noisy situations).
