FAQ
Why use the BT700 instead of my laptop's Bluetooth?
HP says the BT700 provides reliable high-quality audio, remote call control in supported apps and remote firmware updates, which built-in Bluetooth does not.
USB-A or USB-C?
Both are sold. Pick the one that matches the computer port; the headset works with either.
Do I need one if my headset already has one?
Only as a spare or replacement, or to use a headset on a second computer.
