1. Material: metal + plastic
2. By adjusting the magnetic gap of the moving coil, the eddy current loss is reduced and the stroke is increased, presenting rich low-frequency power and providing a wide frequency response
3. 4 strands of 100 cores are tightly wound, and the silver-plated layer effectively enhances the detail resolution and reduces the loss and distortion in signal transmission
4. Ergonomic design, comfortable to wear
5. Humanized pluggable design, expandable and upgradeable Bluetooth headset
6. Frequency response range: 7-40000Hz
7. Cable length: 125+/-5cm
8. Impedance: 25 ohms
9. Sensitivity: 112db
10. Plug type: 3.5mm
11. Pin type: 0.75mm
