Subminiature Omnidirectional Condenser Capsule: The 2.6 mm capsule captures clear, natural-sounding vocals with minimal coloration. Its omnidirectional pattern ensures consistent pickup from all angles, making it ideal for presenters, actors, and performers in controlled sound environments.

Inconspicuous, Lightweight Design: The earset’s tiny capsule and thin boom make it nearly invisible on stage or camera. Weighing just 2.6 grams, it provides exceptional discretion without compromising audio quality—ideal for broadcast and theater applications.

Ergonomic Under-Ear Fit: The flexible, contoured loop fits securely behind the ear. This under-ear design stays firmly in place even during movement. It offers long-wearing comfort, including for users with glasses or sensitive skin.

Detachable and Field-Replaceable Cable: A robust, 1.4-meter cable with a cH-style 4-pin locking connector attaches securely to the earset. The cable is detachable and easy to replace in the field, extending the product’s life and adaptability.

High SPL Handling: The microphone can handle up to 136 dB SPL, allowing it to manage loud vocals or stage noise without distortion. This makes it suitable for dynamic live performances or active speaking environments.

Optional Dual-Ear Stability: The included AT8464x adapter converts the single-ear design into a dual-ear setup for added stability. This is especially useful for active users such as dancers, fitness instructors, or presenters who move frequently.

Wired Power Module with High-Pass Filter: The wired version includes the AT8545 power module with a switchable high-pass filter. This helps remove unwanted low-frequency noise without affecting vocal tone, ensuring cleaner recordings and live transmissions.

Hypoallergenic and Durable Construction: Constructed from hypoallergenic materials, the earset is safe for long use on all skin types. It withstands professional use, resists sweat, and retains its structure in demanding environments.
