Wireless headset with Bluetooth and foldable design

The HRD-308S is a wireless stereo headset that connects via Bluetooth for notebook use. It weighs little and folds for easy transport in a bag. Semi-open earcups with 40 mm drivers deliver sound across a 50–20000 Hz range. The headset runs on replaceable batteries rather than a built-in rechargeable cell.

Check Bluetooth support

Verify that the notebook has Bluetooth audio capability for the wireless link. A 3.5 mm jack adapter is included for wired fallback if Bluetooth is unavailable. The headset uses batteries, so keep spares handy for long sessions. No companion app or memory-card slot is provided for firmware updates or local playback.

Fits mobile setups needing portable audio

The foldable frame and semi-open cups suit travel and office hot-desking. Bluetooth frees the user from cables while the 1.0 m line length and adapter cover wired scenarios. Volume control with 15 steps and active noise cancellation sit on the earcup for quick access. The package includes a user manual and the 3.5 mm adapter only.

How do I decide between the available versions or capacities of this model?
