    Eliminates background noise and focuses on only your voice for optimal team communication.

  • Closed Back Speaker Tags

    Adds a silicone baffle to transform the A40 headset from open-back to closed-back, sealing off the outside world so no sound leaks in or out.

  • Padded Headband

    Synthetic leather headband for added comfort and style.
