Pros & Cons

Pros

  • ✓ USB-C connection with included USB-C to USB-A adapter for PC or Mac

  • ✓ Monaural single-ear design keeps one ear open to your surroundings
  • ✓ Inline controls handle answer/end, mute, and volume
  • ✓ Dynamic EQ tunes voice on calls, shifts to fuller sound for music

Cons

  • ✗ Wired USB only, no Bluetooth or wireless range
