2-Wire Acoustic Tube - Motorola GP300 2-Pin

2-Wire Acoustic Tube Surveillance Kit for Motorola GP300 2-Pin Radios

Clear tube audio with a quick-swap tip when the tube wears out.

Overview

The LEGP300AT-2W is a 2-wire surveillance kit for GP300 and other radios fitted with the Motorola 2-pin accessory connector. Genuine Otto acoustic tube design routes sound through a clear tube rather than a speaker sitting in your ear, which keeps the ear canal open and comfortable over a long shift.

Unlike single-wire earhanger kits, this is a true 2-wire design with a separate microphone wire, and Otto's quick-disconnect earphone adapter means you can swap a worn tube for a fresh one in seconds rather than replacing the whole kit. Built for security teams, event crews, and hospitality staff who need clear, discreet, hands-free audio.

Key Features

• Acoustic tube design means an open ear canal and more comfort over long shifts than an in-ear speaker.
• Separate 2-wire configuration means the microphone cable runs independently of the earpiece, for a lower profile than a combined kit.
• Quick-disconnect earphone adapter means you can replace a worn or split tube in seconds without buying a whole new kit.
• Motorola 2-pin connector means plug-and-play compatibility with Motorola GP300 and other Motorola handhelds using the same 2-pin accessory connector, no adapter needed.

Applications

• Security and crowd control
• Hospitality and retail teams
• Warehousing and logistics
• Event management and production

FAQs

How is this different from the earhanger and flexi earhook kits?
Those sit a small speaker in or behind your ear. This one routes sound through a clear acoustic tube instead, which keeps your ear canal more open. It's also a genuine 2-wire design, with the microphone on its own separate cable.

Will this earpiece work with radios other than the GP300?
Yes. Any Motorola handheld using the same 2-pin connector will work with this kit.

Do I need a licence to use a surveillance earpiece like this?
No. The earpiece itself is just an audio accessory, it doesn't transmit on its own. Licensing requirements apply to the radio and the frequency it operates on, not to earpieces or microphones.

Is the earpiece waterproof?
We haven't seen an official water-resistance rating from the manufacturer for this model, so treat it as splash-resistant at best rather than fully waterproof.
