I bought this headset to help me be more productive when working remotely and using my smartphone for long calls. This headset makes me feel like I'm right at my desk working hands free as I normally do, so I can write or type notes easily.

I've tried a lot of headphone sets. Plantronics are my favorite. It is a very good quality product. This was a exact replacement purchase for a headphone set witch I ruined by entangling the cord in a swinging door. The M175C seems to be the best corded unit available.

I have used this model of headset for over 8 years - excellent sound quality and boom microphone works great. I use this on cordless phones for conference calls, much better for me than a speaker phone option.
