The PRYMEBLU® Adapter allows you to use any compatible wireless headset or other audio accessory with your two-way radio. The PRYMEBLU® Adapter is compatible with thousands of off-the-shelf consumer audio accessories and pairs easily, allowing you to operate wirelessly.

  • Takes power from the radio.  Easy to use, no extra battery charger to worry about.
  • Compatible with thousands of readily available wireless headsets and other audio accessories. (audio accessories not included)
  • Easy pairing process. Stores paired connection to the wireless headset even if the Radio is powered off or adapter is removed from the two-way radio.
  • Several Push-To-Talk options: use the PTT button on the PRYMEBLU adapter to initiate transmissions, or use one of 4 different optional PRYME LE (Low Energy) Wireless PTT Buttons or a Pryme PTT-5 Quick-Disconnect wired PTT switch.


HEARING AID COMPATIBILITY: The adapter should work with hearing aids that support the Bluetooth HSP (headset) profile.  It will NOT work with "streamer" style hearings aids that use the A2DP (streaming audio) profile.  You should contact your hearing aid manufacturer to find out which profiles are supported by your device.  NOTE that some streamer hearing aids offer an optional Phone Clip addon which will allow them to work with HSP devices.  Your audiologist can tell you if such a device is available for your hearing aid.
