I bought this to use with a 5.8GHz Panasonic cordless phone (KX-TGA931T) in a noisy lab environment

It was so convenient to be able to make Skype-type calls to family and friends, and have them hear me (good mic), and me hear them (nice speakers in the headset) even in noisy environments.

I don't especially like the full earmuff effect though since my environment is not very noisy.

It's also comfortable enough for long conference calls (1-2Hrs).Thoroughly recommended for anyone looking to make calls in noisy environments.
