Motorola Solutions introduced new wireless Bluetooth headsets using Sensear’s patented SENSWireless Bluetooth Headset with SENS Technology spatial awareness technology that enhances surrounding voices while providing hearing protection. This feature benefits radio users who work in intermittent or continuous high noise industrial environments but need to hear nearby people, alarms, or alerts.

Choice of Behind-the-Neck or Over-the-Head Styles

RLN6490 - XBT Behind the Head Operations Critical Wireless Bluetooth headsetThe XBT RLN6490 behind-the neck or RLN6491 headband style are designed for Motorola Operations Critical radios and adapters. Both styles provide about 22 hours of battery life based on normal (5-5-90) operation and can be fully recharged in 7 hours. These heavy-duty headsets are rated IP54 and can be used with a NNTN8127 wireless pod for remote push-to-talk operation. The RLN640 can be used with a hardhat and provides 23dB of hearing protection. The RLN6491 headband style has an even better NRR (noise reduction rating) of 25dB.

The SENS technology allows users wearing headsets to hear normal speech clearly when face-to-face with people without headsets. 

The Motorola XBT wireless headsets can be paired with cell phones or any 2-way radio using standard Bluetooth. For MOTOTRBO XPR 6000 series radios, choose the PMLN5712 Bluetooth adapter. XPR 7000 and SL 7000 series radios have factory installed internal Bluetooth and will pair without an adapter. APX radios and XTS 5000 PMLN5792 Mission-Critical Wireless adapters are not compatible because they contain an extra layer of encryption.

How to Choose the Correct Motorola Bluetooth Accessory for your Radio

Radios_BluetoothBluetooth accessories are starting to get complicated for Motorola public-safety and professional radio models. There are now three different types of wireless audio accessories: 

  • Mission Critical with encryption and touch pairing
  • Operations Critical Enhanced with touch pairing
  • Operations Critical Standard Bluetooth

Mission Critical Wireless With 128-bit Encryption is Most Secure

For the most secure wireless communications that is extremely difficult to hack, choose the mission critical models. These are only available for APX series with the internal Bluetooth option or the XTS series with the external PMLN5792 Mission Critical wireless adapter. Motorola’s proprietary “out of band” pairing with 128-bit encryption provides the best secure connection and only takes a few seconds. Pairing takes place when the radio and the audio accessory are within an inch of each other. It does not matter which radio you use – pairing is easy and quick.

Mission Critical Wireless Accessories for APX and XTS

If you have an APX 7000, APX6000, or APX 4000, the internal Bluetooth option must be enabled. At this time, Mission Critical Wireless is only available for APX radios although it is rumored standard Bluetooth might be available in the future. It is possible to use an external third party or MOTOTRBO adapter but it would not support the encrypted accessories.

Mission Critical Wireless AdapterThe PMLN5792 external adapter is compatible with the XTS 5000, XTS 2500, XTS 1500, MT1500, and PR1500. Cancelled models including XTS3000, HT1000, MTS2000, etc. will probably work but are not supported.

Following are the mission critical accessories for APX and XTS models:

  • NTN2570 Earpiece with 12 inch cable includes NTN2571 PTT pod
  • NTN2573 Earpiece with 9.5 inch cable includes NTN2571 PTT pod

Wireless Covert KitOptional wireless earbuds (NNTN8294 11.4 inch cable) or (NNTN8295 45.7 inch cable) are available that attach to the NTN2571 PTT pod. For covert surveillance operations, the  NNTN8295 uses ipod type earbuds or any 3.5mm audio accessory.

Enhanced Operations Critical with Touch Pairing

Enhanced Operations Critical provides intrinsically-safe operation with grab-and-go touch pairing. It is only available with the MOTOTRBO XPR 6300, XPR 6350, XPR 6380, XPR 6500, XPR 6550, and XPR 6580 radios. The PMLN5993 external adapter uses the NTN2570 earpiece.

We tried the PMLN5993 adapter with both the APX 4000 and XPR 7550 after getting conflicting answers from Motorola tech support. We tried multiple times with different accessories without success.

Operations Critical Standard Wireless Bluetooth

Standard Bluetooth adapters are available for all XTS, and XPR MOTOTRBO radio models. The RMN5104 allows the XTS 5000, XTS 2500, XTS 1500, MT1500, and PR1500 to use any standard Bluetooth headset. The PMLN5712 adapter is designed for the XPR6100/6300/6500 series. The XPR5350/5550 mobile radio, XPR7350/7550 portable, and the SL7550 have internal Bluetooth included.

Operations Critical Pod

Following are the certified Operations Critical accessories:

Optional wireless earbuds (NNTN8294 11.4 inch cable) or (NNTN8295 45.7 inch cable) are available that attach to the NNTN8127 PTT pod.
