911 Dispatcher Headsets & PTT Amplifiers
911 dispatch headsets and push-to-talk amplifiers
You're looking at every 911 dispatch headset and PTT amplifier we carry — Plantronics (Poly) EncorePro headset tops, SHG operator headsets, and the 4-wire and 6-wire amplifiers that connect them to your console.
The one thing to settle before you scroll: a dispatch position is two purchases, not one — a headset top, and a push-to-talk amplifier matched to your console's wiring. Pair those two correctly and everything below works on day one.

How to choose a 911 dispatcher headset
A dispatcher headset gets judged on three things, and price isn't the first of them. Start with how many ears it covers.
Next, the microphone — which matters more than the speaker when you're surrounded by other dispatchers talking at once. The models here use a noise-canceling boom mic that rejects the floor around you so the caller and the responding unit hear your voice, not the seat beside you. Worth being precise: the noise control lives on the microphone, not on your ears. None of these are active-noise-cancelling (ANC) headsets, and that's deliberate — a dispatcher has to hear the room, which is the whole reason monaural exists.
Then comfort, because a dispatch headset isn't worn for a call. It's worn for a twelve-hour shift. Lightweight tops and deep cushions are the line between a headset you forget you're wearing and one you're fidgeting with at hour nine. The SHG S 620 with Triple XL ear cushions exists for exactly the operators who've felt that. And if anyone on your floor wears hearing aids, several Plantronics EncorePro models ship in Hearing Aid Compatible (HAC) versions.
Matching the right push-to-talk amplifier to your console
Here's the part that trips up first-time buyers: the headset doesn't connect to your console on its own. It plugs into a push-to-talk amplifier, and the amplifier is what keys the mic and lets an operator toggle between the radio and the telephone. The headset is one half. The amplifier is the other — and the toggle itself has to be built into the console, not the headset.
Every operator top here ends in a Quick Disconnect, the standard dispatch connector. Unclip the headset and the amplifier stays put, wired into the console. That's what makes a shared, around-the-clock position work: each dispatcher brings their own top, clips in at the start of shift, and unclips at the end without anyone touching the cabling.
That same connector is why training works the way it does — drop a Y-cord between the amplifier and the headset and a trainer or supervisor can listen in live on a second top, no rewiring required.
And wireless? It's natural to assume cordless is the upgrade — it usually is in an office. In dispatch the math flips. A wired position has no battery to die in the middle of an incident, nothing to charge overnight, and a lower cost per seat. Wireless PTT amplifiers have their place for operators who truly need to roam, but for a fixed console the wired setup is the one most centers keep coming back to.
Replacing a discontinued Poly or Plantronics dispatch headset
If you landed here because a Poly part finally gave out and you can't reorder it, you're not imagining things. Poly (formerly Plantronics) wound down its specialty dispatch line — the SHS1890 amplifier, the CA22 and P10 adapters — so spare parts and repair paths for those are vanishing. The clean fix is the SHG amplifiers and cables on this page: they speak the same Quick Disconnect, so your existing EncorePro headset tops keep working while the part underneath them gets replaced.
For government-run PSAPs there's a procurement layer that office buyers never have to think about. SHG dispatch gear is built TAA- and NDAA-compliant, which is what clears it through federal and many state purchasing rules. If your center answers to those requirements, that compliance is the difference between a headset you're allowed to buy and one you aren't.

FAQ
Frequently Asked Questions
Yes, in almost every case. A dispatch headset top connects to a push-to-talk amplifier, and the amplifier is what keys the microphone and connects to your radio or telephone console. The only exception is a console with built-in amplification, which uses a non-amplified PTT cable instead of a full amplifier.
It's about how your console is wired. 4-wire is the older standard and is being phased out; 6-wire is the current standard for push-to-talk dispatch. The SHG S D144-Amp serves 4-wire consoles and the SHG S D145-PTT/AMP serves 6-wire — they are not interchangeable, so confirm your console's configuration before ordering.
Yes. Poly discontinued its specialty dispatch amplifiers and adapters, and the SHG amplifiers and cables here are the direct successors. Because they use the same Quick Disconnect, your existing Plantronics EncorePro headset tops keep working — you replace the amplifier or cable underneath, not the whole setup.
Monaural (single-ear) is the dispatch standard because operators need to hear the room and their co-workers while on a call. Binaural (both ears) is the better choice for very loud floors or calls that require total focus, at the cost of some situational awareness.
They use a noise-canceling microphone, which rejects the surrounding dispatch floor so callers hear your voice clearly. That's different from active noise cancellation (ANC) on the ears — these headsets intentionally leave your hearing open to the room, which dispatch work requires.
The SHG dispatch headsets, amplifiers, and cables are built TAA- and NDAA-compliant, which is typically required for federal and many state and municipal PSAP purchases. If you need documentation for a procurement file, contact our team and we'll provide it.
