GREYOLK V4 Open Ear Headphones

The GREYOLK V4 are open-ear true wireless headphones that weigh 32 g and use Bluetooth 5.4. They are aimed at professionals who take frequent calls and want to stay aware of their surroundings while working or exercising.

15 mm drivers with USB-C charging

The 15 mm drivers deliver stereo sound while the open-ear design rests on the ear without sealing the canal. A USB-C port recharges the battery in 2 hours for up to 12 hours of operating time at a 10 m wireless range.

Check Bluetooth version and call needs

Ensure your source device supports Bluetooth 5.4 for a stable connection. The AI noise-cancelling microphone works only for call noise reduction, so buyers who want active noise cancellation for music playback should look elsewhere.
