Motorola NNTN8385A Wireless Neckloop Y-Adapter with Barrel Mic – Beige, for NTN2571 PTT Pod & RLN4920 Neckloop

Motorola NNTN8385A Wireless Neckloop Y-Adapter with Barrel Mic – Beige, for NTN2571 PTT Pod & RLN4920 Neckloop

The Motorola NNTN8385A Wireless Neckloop Y-Adapter (also sold as the NNTN8385) is the genuine Motorola connector at the center of Motorola’s invisible, wire-free covert earpiece system. It joins three parts: the RLN4920 inductive neckloop, the NTN2570/NTN2571 wireless push-to-talk (PTT) pod, and a built-in barrel microphone for talking. With the NNTN8385A, the neckloop sends radio audio to a tiny wireless in-ear earpiece that has no wire or tube to your ear. Your radio stays out of sight, and the earpiece is almost impossible to see. A beige finish and a retention hook keep the setup discreet and in place under clothing.

It’s built for undercover officers, federal agents, executive and dignitary protection details, surveillance teams and high-end security staff, anyone whose earpiece must not be seen.

What Is an Invisible (Inductive) Earpiece?

A standard surveillance earpiece uses a cord or clear acoustic tube to carry audio to your ear, and a trained eye can spot it. An inductive system is different:

• A thin neckloop worn around your neck, under your collar, sends radio audio as a weak magnetic signal.
• A tiny, battery-powered wireless earpiece, worn deep in the ear canal, picks up that signal and plays the audio.
• Nothing connects to your ear, so with no wire or tube, the earpiece is practically invisible.

The NNTN8385A Y-adapter connects that neckloop to Motorola’s wireless PTT pod and adds a microphone so you can talk.

How the NNTN8385A Is Used

Here’s how the parts connect, from radio to ear:

1. Motorola radio: A Bluetooth-ready APX, XPR, SL or XTS radio stays on your belt, in a bag or in a vehicle.
2. Wireless PTT pod (NTN2570/NTN2571, sold separately): Pairs with the radio over Bluetooth and provides push-to-talk.
3. NNTN8385A Y-adapter (this part): Plugs into the pod. One branch has the barrel mic for talking. The other branch plugs into the neckloop.
4. RLN4920 inductive neckloop (sold separately): Worn around your neck under your collar. It carries radio audio to the earpiece.
5. Wireless earpiece (such as the RLN4921, sold separately): A tiny in-ear receiver that picks up the neckloop’s signal.
6. Retention hook: Holds the Y-adapter and cables in place under clothing. Replacement hooks are sold in 10-packs (NNTN8457A).

To set it up:

1. Pair the NTN2571B wireless PTT pod with your radio.
2. Plug the NNTN8385A into the pod.
3. Plug the RLN4920 neckloop into the Y-adapter and wear the loop around your neck, under your shirt collar.
4. Clip the barrel mic where it can pick up your voice, usually at the collar or upper chest, and secure the cables with the retention hook.
5. Insert the wireless earpiece into your ear.
6. Press the pod’s PTT and speak into the barrel mic to transmit.

Why Use the NNTN8385A?

• Truly covert: No visible wire or tube to your ear.
• Built-in barrel mic: Talk without adding a separate microphone.
• Wireless to the radio: The PTT pod links over Bluetooth, so there’s no cord to the radio.
• Beige color: Blends with skin tones at the collar.
• Retention hook: Keeps the adapter and cables secure under clothing.
• Modular: Replace just the Y-adapter, neckloop, hook or earpiece if one part wears out.
