Customer Reviews (4.8 / 5 · 5 reviews)

Jacob ★★★★★

The active noise cancellation on this headset is excellent—it blocks out the hum of my office fan completely. Controls on the earpiece are easy to reach and adjust without fumbling.

Olivia ★★★★★

Wore these through a full eight-hour shift of calls and still had battery left, which surprised me since I usually have to charge headsets midday. The on-board controls are easy to find by touch, so I'm not fumbling for my phone every time someone starts talking.

Eli ★★★★★

The ANC actually kills the drone of the HVAC unit in my office, which I didn't expect at this price. Battery lasted just over 22 hours on a single charge during a two-day trip, and the on-ear controls are easy to find without looking.
