  • Speech Intelligibility

    The 5x5 Pro III features an eartip-style receiver, which provides better speech intelligibility than an earmuff-style headset in quiet to moderately noisy environments.
  • Comfort

    The adjustable springs allow users to alter lateral pressure on the head and optimize load distribution and wearer comfort.
  • Push-to-Talk

    Push-to-Talk switch is available to order for ease of use.
  • FAA TSO Approval

    The 5x5 Pro III is approved for aviation use under Federal Aviation Administration TSO C57 and C58A.

With soft head-pad cushions, adjustable headband, and on-the-head weight specs of only 3/4 oz., the 5x5 Pro III is a single receiver headset that provides true lightweight comfort. Single receiver features single pliable, soft ear tip receiver. High quality electret microphone has flexible boom, which can be worn on left or right side. It can be worn without the headband, by clipping to eyeglass bows or after market custom earmold. Order Push-to-Talk switch for aircraft that is not equipped. FAA TSO C57 & C58 Approved.
