The MIC-SJ66 has been designed primarily with the sports and aerobics industry in mind and is therefore built to withstand the everyday demands of an active lifestyle. The construction of this headband microphone offers a high degree of protection against the ingress of sweat. Precise placement is obtained with the 4mm diameter flexible gooseneck, and the condenser capsule is highly efficient at noise cancellation, helping prevent feedback or interference from crowd noise etc.
