Air tube earphones for radiation reduction

These in-ear headphones use an air conduit to reduce radiation exposure by 98 percent during calls and music playback. The 3.5 mm connector fits most mainstream mobile phones. A built-in microphone with answer and on/off button handles voice communication. Soft silicone earplugs provide sound isolation and comfort.

Check your phone jack and OS switch

Verify that your device has a 3.5 mm headphone socket before ordering. The inline CNC switch must be set to "I" for Apple phones or "N" for Android phones to ensure microphone and media controls work correctly. The single-ear coupling design means audio is delivered to one ear only.

Sustained comfort with passive isolation

The lightweight 0.01 kg build and soft silicone tips remain comfortable during long listening sessions. Passive sound isolation blocks ambient noise without active electronics that could fatigue the ear. The 10 mm dynamic driver handles continuous playback at rated power without distortion. Retractable cable storage prevents tangling when not in use.

Questions about this item

What comes in the box and is anything else needed to use them?

The package includes the in-ear earphone with a built-in microphone and a 3.5 mm plug. No extra items are required if your device has a 3.5 mm jack.

How do I choose between the two switch positions marked I and N?

Set the switch to I for Apple phones or N for Android phones to match the headset's control wiring.

What does the 98 % radiation-reduction claim mean in practice?

The air-tube design replaces the usual wire to the earpiece with a hollow acoustic tube, so electromagnetic fields from the phone do not travel up to your ear.
