Purpose-built listen-only earpiece

The Logitech CA01C-25-35L2 is a receive-only acoustic-tube earpiece designed for professionals who need discrete audio from a speaker microphone. It connects through a 3.5 mm jack and includes three earmolds for a secure in-ear fit.

Suited to security and radio users

This unit serves police, security and law-enforcement personnel who rely on compatible speaker microphones from brands such as Motorola, Kenwood, Baofeng, Icom and Harris. It is not for users who require a transmit microphone, intrinsically safe certification or waterproof construction.

Cable reach and clear reception

The cord measures 11.8 inches relaxed and stretches to 23.5 inches, giving enough slack for shoulder-worn mics without excess bulk. An 18 ohm speaker and active noise cancellation deliver intelligible audio in loud surroundings, while the 2.5 mm diameter tube keeps the profile low.
