There's a test of EDR bluetooth USB sticks in c't magazine 21/2005 on page
190ff. Accordingly, the sticks with the best reception and range were
Cellink BTA-6030 and Planex BT-01UDE. They both feature -90dBm sensitivity.

You can't measure the range with a bluetooth headset because they're class 3
devices with less range than the Neo1973, which is class 2.
