Audio-Technica BP893x-TH Omnidirectional Earset with Detachable Cable and AT8545 Power Module, Beige

The Audio-Technica BP893x-TH is a high-performance omnidirectional earset microphone designed for professional vocal applications. With its ergonomic under-ear design and an extremely unobtrusive 0.2" boom, it offers both comfort and discretion. Whether you're performing on stage or presenting in a high-stakes meeting, this mic delivers clear, natural vocal pickup while remaining nearly invisible. Its advanced subminiature condenser capsule ensures outstanding audio reproduction, comparable to that of a top-tier lavalier microphone.

This earset hooks around the back of either ear, with the boom extending from below the ear for discreet positioning. The BP893x-TH is engineered to meet the demands of both wired and wireless applications. It includes a detachable, field-replaceable cable and the AT8545 power module, which offers a high-pass filter to significantly improve sound pickup. Additionally, the mic is constructed from hypoallergenic materials, making it suitable for long-term wear. As an added benefit, the package includes the AT8464x Dual-Ear Adapter Kit, converting the single-ear MicroSet into a more secure and comfortable dual-ear unit.
