PRODUCT DESCRIPTION
The Bluetooth® modules built into PCs and notebooks are general devices that do not map all the functions needed to operate a hands-free system or a headset in conjunction with a Unified Communications software solution. A USB WL Adapter is therefore required.
The USB WL Adapter gives you:
- High quality audio playback (A2DP)
- Volume level synchronised with the operating system (macOS / Windows)
- Detection of microphone use and switching to HFP
- Fully synchronised buttons on the beyerdynamic device The following Bluetooth® profiles are supported:
- HFP (wideband voice / HD Audio (l6kHz); AT commands from the hands-free channel are understood and converted into commands for the USB HID device.)
- A2DP (high quality audio playback; AVRCP for volume synchronisation; profile commands are converted into commands for the USB HID device.)
FIRST STEPS
Removing from packaging and storing
- Remove the USB WL Adapter from the packaging. This provides the best protection and prevents damage
FIRMWARE UPDATE
Firmware updates are carried out via USB-HID using the beyerdynamic Update Hub: https://byr.li/firmwareupdate
SUPPORTED AUDIO CODECS
The USB WL Adapter supports the SBC audio codec.
Please note that only the codecs available in the playback device can be used for audio transmission.
Playback device and the beyerdynamic Bluetooth® device automatically select the best mutually available codec: In this case SBC.
