That's great; thanks for listing those BT headsets.
One important thing to know, however, is that those headsets, like all BT devices, have a limited range, and will start to crap out if you walk to another room. By contrast, the professional-grade cordless headsets use DECT 6.0, which has a much longer range. Using my Jabra DECT 6.0 headsets, with the base station and phone upstairs, I can walk downstairs, into the garage, or out on my driveway, and several houses away, and still have a clear conversation.
Of course, they're expensive, but you get what you pay for.
