Sennheiser EZX60, EZX80, MB PRO2, MB PRO1, MM400-X User Manual

Bluetooth® Disclaimer

Your computer or laptop may have bluetooth capability built into it, but
not all computers will have the correct headset profiles, hands free
profiles, or bluetooth version drivers to make it fully compatible with our
bluetooth headsets.

If you can determine the name of the company that produced your
computer's bluetooth chip, you can try to visit their website in an
attempt to obtain the latest drivers/updates for your chip. If current
drivers are not an option or if that didn't fix the issue, then to ensure full
compatibility you may need to purchase our bluetooth adapter dongle
named BTD800USB.
