Getting started

Pairing the headset with Bluetooth® devices

CAUTION: Danger of malfunction!
The transmitted radio waves of mobile devices can impair the operation of sensitive and unprotected devices.

  • Only use Bluetooth where it is permitted.

The headset complies with the Bluetooth 5.0 standard. Bluetooth devices need to support the “Hands-Free Profile” (HFP), the “Headset Profile” (HSP), “Audio Video Remote Control Profile” (AVRCP) or the “Advanced Audio Distribution Profile” (A2DP).

To transmit data via Bluetooth, you first have to pair your headset to a wireless device. The delivered dongle is already paired with the headset. The headset can save up to eight paired devices. If you pair the headset with a ninth device, the device with the oldest activity in the pairing list will be overwritten. If you want to re-establish a connection with this device, you have to pair it again. The headset can be connected to two of the paired devices at the same time. You can only connect another device by disconnecting one of the already connected devices.Epos Sennheiser Adapt 360 Over-Ear Bluetooth Headset 15
