Trantec SJ66-BK (HM-66) Fitness Headset Microphone, 3.5mm Locking Jack - Black
DETAILS
The Trantec SJ66-BK is a Super Cardioid Condenser Fitness Headset Microphone built specifically for sports and aerobics instructors, featuring sweat-resistant construction, a flexible 4mm gooseneck for precise placement and efficient noise cancellation.
The Trantec SJ66-BK has been designed specifically with the sports and aerobics industry in mind, built to withstand the everyday rigours of an active lifestyle where a standard headset microphone simply would not survive.
Whether worn during high-intensity aerobic classes, spinning sessions, gym floor instruction or any other physically demanding fitness environment, the SJ66-BK provides the durability, sweat protection and audio performance that fitness professionals rely on session after session.
Sweat-Resistant Construction
The SJ66-BK's construction offers a high degree of protection against the ingress of sweat — one of the most common causes of headset microphone failure in fitness instruction environments. This makes it a genuinely practical and cost-effective long-term investment for studios, gyms and fitness facilities where microphones are in regular daily use and exposed to the inevitable moisture of an active class environment.
Precise Placement & Noise Cancellation
A 4mm diameter flexible gooseneck allows the condenser capsule to be precisely positioned and held firmly in place throughout even the most vigorous movement — ensuring consistent microphone placement and a reliable, stable audio signal throughout the session. The super cardioid electret condenser capsule is highly efficient at noise cancellation, helping to prevent feedback and minimise interference from crowd noise, music and other ambient sound sources in busy fitness environments. With a frequency response of 20Hz to 16kHz and a maximum SPL of 125dB, the SJ66-BK delivers clear, natural vocal reproduction across the full range of the human voice.
Compatible with Trantec S4.10W Systems
The SJ66-BK connects via a 3.5mm locking screw jack connector, making it compatible with the Trantec S4.10W beltpack transmitter and other compatible wireless systems using the same connector type. The 1500mm cable provides ample length for comfortable routing from the headset to the beltpack during use.
