Most people searching for headphones for Polycom desk phones actually need a headset with a microphone, and the good news is that every VVX has a dedicated headset port. This is one of the easier desk phones to fit. The catch is that "compatible" depends on which VVX you have. Older models give you one option, newer ones give you three, and a wireless headset needs one extra cable that most people forget until it will not answer calls.
So here is the compatibility map, grouped the only way that matters: by the ports on the back of your specific phone.

Polycom VVX headset compatibility by model
Find your phone in the left column and the right column tells you what connects. The RJ9 headset port is on every model, so a corded headset is always an option. The newer phones just add more ways in.
| Polycom VVX / Poly Edge model | Headset ports | What connects | EHS cable for wireless |
|---|---|---|---|
| VVX 101, 150, 201, 300/301, 310/311, 400/401, 410/411, 1500 | 1 × RJ9 | Corded QD headset + RJ9 bottom cable, or DECT wireless | Poly APP-51 or Jabra Link 17 |
| VVX 250, 350, 450 | RJ9 + USB | The above, plus USB headsets | Poly APP-51 or Jabra Link 17 |
| VVX 500/501 | RJ9 + 2 × USB | The above, plus Bluetooth via a USB adapter | Poly APP-51 or Jabra Link 17 |
| VVX 600/601 | RJ9 + 2 × USB + Bluetooth | All of the above, plus direct Bluetooth pairing | Poly APP-51 or Jabra Link 17 |
| Poly Edge E-series (E100 to E550) | RJ9, with USB or Bluetooth on some models | Corded QD + bottom cable, USB or Bluetooth per model | Poly APP-51 or Jabra Link 17 |
| Poly Edge B-series (B10, B20, B30) | 1 × RJ9 | Corded QD headset + RJ9 bottom cable, or DECT wireless | Poly APD-80. No Jabra EHS option |
One rule holds across the whole range: a corded solution is always two pieces, the headset and the RJ9 bottom cable that connects its QD plug to the phone. Everything confirmed for these phones sits on our Polycom headsets page.
Corded headsets for a Polycom VVX phone
A corded QD headset plus the Polycom RJ9 bottom cable is the most reliable option for any VVX, on any model. It uses the dedicated headset port and needs no amplifier. These are the ones worth buying:
- Plantronics EncorePro HW510. The single-ear call-floor standard, one ear open for the room.
- Plantronics EncorePro HW540. Converts between three wearing styles, so one model suits a whole team.
- Plantronics EncorePro HW710. Leatherette cushions for people wearing it all day.
Each needs the matching RJ9 bottom cable to reach the VVX: a Poly U10P bottom cable for the Poly headsets, a Jabra GN1200 smart cord for Jabra models.

If your VVX is a 250, 350, 450, 500/501 or 600/601, it has a USB port, and a USB headset plugs straight in with no bottom cable. But this is where "compatible" gets a caveat worth knowing before you buy.
The safe current USB picks are the Poly Blackwire 3320 for dual-ear or the Blackwire 3310 for single-ear, both current-generation and Teams-certified. Confirm your VVX firmware is up to date, since USB headset behavior on these phones is firmware-dependent.
Wireless headsets for a Polycom VVX phone
A wireless headset connects to any VVX, but to answer and end calls from the headset itself, which is the whole point of going wireless, you need one extra piece: an EHS cable. Without it the headset still works, but you are walking back to the phone to pick up.
EHS (Electronic Hook Switch) cable — A cable that lets a wireless headset's base electronically lift the desk phone's line, so you can answer and end calls from the headset up to a few hundred feet away. On a Polycom VVX it is the Poly APP-51 for Poly headsets, or the Jabra Link 17 for Jabra headsets.
The cleanest option is a bundle that already includes the right cable. The Poly CS540 with the Polycom EHS cable ships ready to answer remotely on any VVX, and it also supports the Poly Edge E-series. The CS540 itself is the reason to pick it: light, long-range DECT, and a user-replaceable battery.
If your phone is a VVX 600/601, its built-in Bluetooth means you can pair a Bluetooth headset directly with no EHS cable at all. Once the cable arrives, pairing the base to the phone takes a few minutes, and we walk through it step by step in our guide to the polycom ehs cable setup. One planning note for larger offices: if your VVX has a sidecar expansion module, the Poly APP-51 needs a short extension cable to reach it.
Poly Edge phones, and the one difference that catches people out
The Poly Edge E-series replaced the VVX line and behaves almost identically: same RJ9 headset port, same Poly APP-51 EHS cable, same corded and wireless options. If a headset works on your VVX 450, it works on an Edge E450.
The B-series is where it changes. Poly Edge B10, B20 and B30 use the Poly APD-80 EHS cable instead of the APP-51, and there is no Jabra EHS equivalent for them at all. Order an APP-51 for an Edge B and it will not answer your calls. This one catches people who assume the whole Edge range is interchangeable.
Older Polycom phones
Everything above covers VVX and Poly Edge. If you are running an older desk phone, the SoundPoint IP range takes a different set of pairings, and we cover those separately in our guide to the Polycom SoundPoint IP 550 headset options and the rest of that line.
Frequently asked questions
What headsets are compatible with Polycom phones?
Headsets compatible with Polycom phones fall into three groups: corded QD headsets with an RJ9 bottom cable, which work on every VVX and Poly Edge model; USB headsets, on the VVX 250, 350, 450, 500/501 and 600/601; and DECT wireless headsets, which need an EHS cable to answer remotely.
Do I need a special cable for a headset on a Polycom VVX?
Yes, in most cases. A corded headset for a Polycom phone is always two pieces: the headset and the RJ9 bottom cable. A wireless headset needs an EHS cable, either the Poly APP-51 or the Jabra Link 17, to answer calls away from the desk. Only a USB or Bluetooth headset connects with nothing extra.
Can I use a wireless headset with a Polycom VVX phone?
Yes. A wireless headset compatible with a Polycom phone works on every VVX model. Add the Poly APP-51 or Jabra Link 17 EHS cable and you can answer and end calls from the headset up to a few hundred feet from the desk.
Why does my headset buzz on my Polycom VVX?
Buzzing on a Polycom phone headset usually means the model is outside the certified range. Plantronics corded headsets other than the EncorePro 500 and 700 series can produce an audible buzz on VVX phones. Switching to a certified model with the correct RJ9 bottom cable resolves it.
Are Polycom VVX headsets compatible with the newer Poly Edge phones?
Mostly yes. The Poly Edge E-series uses the same RJ9 port and the same Poly APP-51 EHS cable as the VVX range, so headsets carry straight across. The Edge B-series is the exception: it needs the Poly APD-80 EHS cable instead.
What is the best headset for a Polycom phone in a noisy office?
For an open-plan floor, a binaural noise-cancelling model such as the Plantronics EncorePro HW540 covers both ears and keeps room noise off the call. If you need to hear colleagues alongside the call, the single-ear HW510 is the better fit.
Start with the ports on the back of your phone and the rest falls into place. Every VVX takes a corded QD headset with the RJ9 bottom cable, newer ones add USB, and wireless just needs the EHS cable to answer remotely. Match your model against the table above, then shortlist on our polycom wireless headsets page, or call and we will confirm the exact cable your phone needs in a minute.
