## Description

From the manufacturer

Review: The headset is comfortable - I could see myself with this headset for hours because it's not too heavy it's very light. I did end up returning it because the noise cancelling is not up to par with the Sennheiser SDW series it was to replace. I have instead decided to buy a new battery and earpads for the Sennheiser SDW, I thought the C20 would have been an upgrade but it actually is not. For all day comfort and battery life highly recommended, just shop around if you need great noise cancelling.
