I keep hearing that bluetooth is only good for 30 feet, but look at

MOST Bluetooth devices conform to class 2 - which is up to 10 meters
transmission range. My hearing aids use class 3 to talk to each other
and class 2 to talk to my I-Phone. ( 10 cm transmission)
A class 1 bluetooth device can transmit up to 100 meters. Those
wireless headphones excede class 2 but are not class 3. Mabee they are
not TRUE bluetooth but some other semi-standard running on the 2.4Ghz
band?
