Listen-Only Acoustic Tube Earpiece

This listen-only acoustic tube earpiece connects to any device with a 3.5 mm earphone jack, including two-way radios, speaker mics, remote mics and MP3 players. A soft silicone ear bud sits securely in the ear while a transparent tube carries sound discreetly. It is built for professionals who need clear, private receive audio without a microphone.

Upgrade From Basic Earbuds

Standard earbuds fall out during movement and leak audio in quiet environments. The acoustic tube design keeps the earpiece stable and directs sound straight into the ear canal, making the switch worthwhile for security, event or marine crews who operate in noisy or windy conditions. Users who require push-to-talk transmission should choose a full surveillance kit instead.

Capacity And Headroom

The single 3.5 mm mono plug handles receive-only audio from compatible radios and audio players with no external power needed. It covers everyday voice communications and low-volume monitoring tasks. The tube can trap moisture in humid or wet conditions, which mutes audio until the tube is blown clear, so it is not suited for prolonged exposure to rain or heavy spray.

Questions about this item

Which devices accept the 3.5 mm plug on this listen-only earpiece?

It connects to two-way radios, speaker microphones, remote microphones, MP3 players and any other audio accessory that has a 3.5 mm earphone jack.

How do I fit the acoustic tube and silicone ear bud so the earpiece stays in place?

Insert the soft silicone ear bud into your ear canal until it seals, then route the transparent acoustic tube over the top of your ear; the tube holds the bud securely without a separate clip.

What should I do if moisture gets inside the acoustic tube and the audio cuts out?

Remove the earpiece, blow firmly through the tube to expel the moisture, then reinsert it; the sound will return once the tube is dry.
