Motorola APX XTS Completely Discreet Wireless Covert Surveillance Accessories

Wireless Covert Radio EarbudThe Motorola RLN4922 completely discreet earpiece is a covert wireless audio accessory inserted in the ear compatible with most two-way radios using a 2 or 3 wire surveillance kit. The earbud connector on the surveillance kit connects to the included RLN4920 wireless neckloop worn under your clothing. The push-to-talk switch and microphone on the wired surveillance accessory is still used. Recently, the RLN4922 was redesigned for more comfort, made smaller, and improved technically.

New Completely Discreet Mission Critical Wireless Covert Kit

Wireless enhanced Bluetooth Covert EarpieceUsers with the Motorola APX and enhanced Bluetooth option or XTS radios with the external PMLN5792 adapter have new options for covert surveillance. Motorola’s new NNTN8434 Wireless Covert Kit includes the RLN4922 wireless earbud, NNTN8385 Y-adapter, and NTN2571 PTT pod.

Now the radio can be placed in a backpack, briefcase, or purse up to 30 feet away. The NTN2571 PTT pod uses easy touch pairing. All you need to do is place the pod within an inch or two from the radio and it will automatically connect. Now a user can select any radio available and be ready for covert two-way communications immediately. The enhanced Bluetooth is encrypted and cannot be monitored like standard Bluetooth devices.

Basic Wireless Covert Kit Uses 2 Wire Earbud Headphones

Person listening to music or using smartphoneAlso available is the NNTN8296 Basic Wireless Covert Kit that includes 3 sets of earbuds and a 3.5mm adapter for connecting any off-the-shelf commercial earphone accessory. Radio users appear to be using a smartphone or listening to music. 

The NTN2571 must be ordered separately. There is also an optional carrying case (RLN6485).

Typical battery life for the NTN2571 PTT pod is 8 hours but carrying a second pod will provide remote PTT and a spare power source for up to 16 hours of use. The pod uses a standard micro-USB charger.

For more information see the Motorola brochure APX and XTS Mission Critical Wireless Covert Solutions

The RLN4922 Completely Discreet Earpiece and wireless covert accessories are also available for MOTOTRBO Operations Critical Bluetooth. The NNTN8127 PTT pod is the operations critical wireless (OCW) version used with the NNTN8385 Y-adapter. You will also need to use the PMLN5712 or the PMLN5993 Bluetooth adapter with touch pairing for XPR 6000 series radios.


New Motorola XBT Wireless Headsets Feature SENS Technology

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.

XBT Bluetooth Headset FeaturesXBT Wireless Headsets Use Standard BluetoothXBT Headsets Provide  3 ways to communicate

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.

New RLN6500 MOTOTRBO Bluetooth Kit Replaces HK200

MOTOTRBO RLN6500 Bluetooth Accessory KitMotorola Solutions recently cancelled pending HK200 Bluetooth headset orders after running out of stock. The recommended replacement is the new RLN6500 MOTOTRBO Bluetooth Accessory Kit. The RLN6500 has a comfortable swivel earpiece connected to a pod with clothing clip.

The new design provides a more professional appearance and prevents others from thinking your employees are on their cell phones. Additional earpiece styles will be added in the future.

RLN6500 ChargerThe RLN6500 provides enough battery life for a full 8-10 hour shift unlike most cellular style Bluetooth headsets.

Included is a compact 120V AC charger with cradle for quick and easy charging for the next shift.

Designed for MOTOTRBO DMR Bluetooth Enabled Radios

The RLN6500 is designed to be used with MOTOTRBO Bluetooth enabled radios including the SL 7550, XPR 5350, 5550, XPR 7350, 7550. It is also compatible with XPR 6100, 6300, and 6500 series radios using the PMLN5712 adapter.PMLN6397 Replacement Swivel Earpiece and In-line Mic

It is easy to share among employees with extra PMLN6397 earpieces with in-line mic (pack of 3). The earpiece has a antimicrobial coating for healthcare applications.

Once paired, the headset will reconnect with the radio the next time it is turned on. It is not compatible with the PMLN5993 Bluetooth adapter with touch pairing so you will need to keep it paired with the same radio. The RLN6500 is not compatible with cell phones so you are less likely to lose them due to theft.

Lower Cost Alternative for MOTOTRBO Bluetooth Audio Accessories

The RLN6500 is priced lower than the Operations Critical NNTN8295 wireless earbud with pod and the NNTN8125, NNTN8126 earpieces.

Plantronics-85550-01 M50For those who need a HK200 replacement with long battery life that will also pair with a cell phone, we recommend the Plantronics M50 85550-01.

It has standard Bluetooth 3.0, provides 9-11 hours of typical use, and uses a micro-USB charger connector.

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:

  • NNTN8125 Earpiece with 12 inch cable and NNTN8127 PTT pod
  • NNTN8126 Earpiece with 9.5 inch cable and NNTN8127 PTT pod
  • 89409N HK200 earpiece headset

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

Advantages of New Motorola DMR MOTOTRBO XPR 5550

New Motorola XPR 5000 Series Supports Analog and Digital DMR

Motorola MOTOTRBO XPR 5350 & XPR 5550 Motorola’s newest base/mobile offering to the MOTOTRBO DMR platform is the XPR 5000 series. Introduced in the VHF and UHF bands, the radios can be programmed with up to 1,000 analog and digital channels providing easier migration and interoperability. 

The flagship XPR 5550 includes a color display with day and night modes for easier viewing. The XPR 5350 has a numeric channel display and 32 channel capability.

An internal GPS receiver and text messaging is standard on both models.

New XPR 5000 Series Includes Embedded Wireless Bluetooth for Voice and Data

Workers can monitor and respond to voice radio traffic when not in the vehicle using any standard Bluetooth headset. This can enhance productivity by giving your workforce the ability to stay in touch when away from the mobile radio.

Bluetooth is also an easy way to connect hand-held scanners, bar code readers, and other data collection devices. You will need to purchase the HKVN4088 optional software license at a cost of $50 to enable the data transfer feature. MOTOTRBO already supports many independent software applications that enhance mobile worker productivity.

XPR 5550 5 Line Color Display Provides Day and Night Modes for Easier Viewing

Text messaging, mobile workforce productivity applications, and large channel lists are easily managed with the XPR 5550 5 line color display. The bright display can be viewed easily in broad daylight or in low light environments with night mode. Four programmable buttons can be labeled for your operational needs and a home button provides an easy user interface.

Dual Function Channel/Volume Knob Eliminates Rocker Switches

The XPR 5000 series incorporates a single knob for both volume and channel control. With a short press of the knob you can change your volume and channel easily. The XPR 5000 platform also has a nice feature called “intelligent audio” that increases or decreases the volume automatically if surrounding noise conditions change.

Bluetooth Dual-Muff Headset for High Noise Environments

Peltor MT1H7F2WS3 Tactical XP Headset

UPDATE 12/12/13 – This product was cancelled and replaced by the 3M Peltor WS100.

3M Peltor manufactures a comfortable, dual-muff headset called the Tactical XP for anyone needing wireless connectivity to a two-way radio or cellular phone equipped with standard Bluetooth. Designed for high noise environments it has a high quality electret noise-cancelling boom microphone.

It can also be used to prevent harmful sounds like gunshots, loud machinery, or other impulse noises that could affect your hearing. Electronic microphones mounted on the muffs amplify surrounding sounds during quiet times but instantly provide 24dB NRR. You can hear normally with the headset on but you will have excellent hearing protection if a harmful sound occurs.

This headset is FM Approved and carries an intrinsically-safe rating. It is easy to pair with a Bluetooth phone or two-way radio adapter. It is powered by (2) AA batteries and automatically shuts off after two hours. The headset remembers the last settings used and only needs to be paired once.

Bluetooth Tactical XP Hardhat Style

The black Tactical XP has replaceable ear seals and is built to last. Available in headband style (MT1H7F2WS3) or with hardhat helmet attachments (MT1H7P3E2WS3), it carries a 12 month warranty.

We have tested the Tactical XP using the Motorola RMN5104 Bluetooth adapter for the XTS 5000 radio and the PMLN5712 MOTOTRBO adapter for the XPR6550 with excellent results. The PrymBLU adapters pair easily with the headset also.
