Claire U. ★★★★★

I’m really impressed with how comfortable these are for long calls—the ear cushions don’t get hot after hours of use. The active noise cancellation is strong enough to block out my noisy AC unit, which was a pleasant surprise. Getting two for the price of one just sealed the deal for me.

Emily ★★★★★

The noise cancellation actually cuts out the background hum of my office, so callers stopped asking if I was in a wind tunnel. My wife claimed the second one for her work calls and now we both use them daily.

Steven J. ★★★★★

Got two of these for the price of one, so my wife and I each took one for our work-from-home calls. The environmental noise cancellation actually cuts the leaf blower outside my window down to a faint hum, and the mic picks up my voice clearly on the other end.
