Air-tube earbuds for low-radiation listening

These wired in-ear headphones use a hollow acoustic tube to deliver sound while keeping the driver away from the ear canal. The design targets users who want to minimise exposure to electromagnetic fields during calls or music playback. A 3.5 mm plug provides universal compatibility with smartphones, tablets, computers and MP3 players. The single-ear coupling keeps one ear free for situational awareness.

Passive isolation with volume trade-off

Silicone mushroom tips provide passive noise reduction rated at 99 per cent EMF and RF protection according to the supplier. Sound travels through the air tube, which attenuates volume compared with conventional earbuds; users may need to raise the device volume to compensate. The cable uses TPE sheathing for durability and includes a collar clip to secure the microphone. Weight is 0.045 kilograms.

Replaces standard wired buds

The upgrade makes sense for anyone who spends long hours on calls and wants an alternative to traditional drivers sitting directly in the ear. It is not suited for listeners who prioritise maximum loudness or bass impact, as the tube architecture inherently limits output level. The built-in push-to-talk button and media controls handle basic call and playback functions without touching the phone.

Questions about this item

Will the 3.5mm plug work with my older smartphone that still has a headphone jack?

Yes, the universal 3.5mm jack fits any device with a standard 3.5mm audio port including older smartphones, tablets, MP3 players and computers.

How can I check that the air-tube design is actually reducing radiation during a call?

The transparent acoustic tube carries sound through hollow air channels instead of electrical wires to the earpiece, delivering 99% protection against EMF and RF radiation.

Does the package include spare ear tips or must I buy them separately?

The earbuds come with silicone mushroom-head tips in changeable sizes; a collar clip for securing the cable and microphone is also included in the box.
