Comfortable, very portable and easy to use. It folds almost flat and has a mesh carrying case.

Its OK. Speech and mic quality are OK but be aware when I installed it it would randomly crash my PC until I downloaded their Hub software and upgraded the headset firmware. I'm using Win 10 Pro, Version 1709, OS Build 16299.19 (Latest Features install)

Very pleased with my purchase. The noise cancelling is not the best, and if the volume is too high on the headphones and not loud enough on the phone I get an echo, both issues are easy enough to work around, so not a big deal for me.

I bought a C315 a couple months ago and liked it so well I just ordered two more (for other devices). It's lighter and more comfortable than my C720 headset, and I don't really need or want Bluetooth. The C720 keeps slipping off my head -- but the C315 stays put.

attractive.well made.comfortable and sound decent

decent build quality

nothing when on sale

Noise cancellation is not so great

I have used my device for approx. 2 weeks, and it works well. I would but it again, but maybe a wireless next time!
