Samson SW7A7SQE-K5 AirLine 77 Fitness Wireless Headset

The Samson AirLine 77 Fitness Wireless Headset System (SW7A7SQE-K5) is engineered specifically for fitness instructors and active performers who need reliable, hands-free audio without the encumbrance of a traditional bodypack transmitter. The AH7 headset transmitter integrates the wireless transmitter directly into a lightweight, adjustable headband that sits comfortably around the ears and behind the head. This design eliminates dangling cables and clip-on transmitter packs that can shift or bounce during high-energy classes, letting instructors focus entirely on their teaching.

At the heart of the system is the Samson Qe condenser microphone with a sweat-resistant capsule that resists corrosion from prolonged moisture exposure — a critical feature for environments where perspiration is constant. The bidirectional pickup pattern focuses on the instructor's voice while reducing ambient gym noise and minimizing the risk of feedback. Operating at 479.1 MHz, the system delivers clear wireless audio transmission to the included receiver, which connects via XLR to a venue's sound system. The transmitter runs for up to 8 hours on a single AAA battery, providing enough power to cover even the longest days of consecutive classes without interruption.
