These are great headsets, earphone audio is exceptional as well as the microphone. Out of nearly 3 years of owning several of these, I have yet to can any connection issues with the wireless. They are comfortable as an all-day headset in the office or dry outdoor setting and fit securely on ear.
Exceptional clarity; comfortable; great wireless range; long lasting battery; and outstanding product support staff
