The XLT SE110-35TC listen only earpiece is the ideal accessory for use in loud environments, additional privacy, and stealth communications. Its clear acoustic coil tube wraps behind the ear discreetly, and its mushroom tipped earpiece fits securely inside your ear canal. The earpiece is available in a 3.5mm threaded audio connector for a secure fit in the auxiliary port of speaker mics with threaded audio ports, such as those used by law enforcement. The SE110-35TC includes the clear tube, earpiece, and coiled connector wire with lapel clip.
