Earbuds that deliver sound through hollow air tubes instead of wires, so nothing electronic sits in your ear.
How air tube technology works
The final section of the cable is a hollow tube rather than a wire. Sound travels up it as acoustic waves, the same way a stethoscope carries sound, so there is no speaker coil, no wiring and no electronics sitting next to your head. The braided nylon cord below it is infused with copper, which DefenderShield specifies as shielding against extremely low frequency (ELF) emissions from the cable itself.
Because these are wired headphones, there is no Bluetooth transmitter and no radio frequency signal at your ear.
Features
- Air tube acoustic delivery, no electronics at the ear
- Copper-infused braided nylon cord for ELF shielding
- Wired connection, so no Bluetooth and no RF signal
- Built-in microphone and audio controller for calls and playback
- Three ear tip sizes plus sports tips for a secure fit
- Two clips to keep the air tubes in place
Specifications
- Connector: 3.5 mm
- Cord length: approximately 108 cm from plug to speaker housing
