The Poly Edge series is unusually flexible for a desk phone — RJ9, two USB-C ports, a 3.5mm jack, EHS support, and Bluetooth built into some models. That means more headset options than most phones, but also more ways to pick the wrong one. Here's what connects how.
Quick answer

Which Edge models this covers
Edge B series — the entry tier: B10, B20, B30.
Edge E series — larger screens and more features: E100, E220, E300, E320, E350, E400, E450, E500, E550.
The headsets below work across both families. The B series carries a 3.5mm jack, an RJ9 port, and EHS support, so the same options apply — the E series simply adds USB-C and, on some models, Bluetooth.
What makes the Edge series flexible
Most desk phones give you one or two ways to attach a headset. The Edge E gives you four, and that's the practical reason it's worth understanding before buying:
- RJ9 headset port with a dedicated headset key — for corded QD headsets with a Poly bottom cable.
- Two USB-C ports — one on the back, one on the right side facing the phone. A USB headset plugs in and the phone recognises it directly.
- 3.5mm jack — for headsets with a standard analogue plug.
- EHS support — for wireless headsets to answer and end calls remotely.
- Bluetooth 5.0 on some E-series models — pair a Bluetooth headset straight to the phone with no dongle.
The phone also carries Poly's NoiseBlock AI and Acoustic Fence on its own speakerphone, and the E series includes Microban antimicrobial protection on the handset.
Myth
Any Plantronics QD headset will work with a Poly Edge phone as long as I have a bottom cable.Reality
You need the right bottom cable specifically. Poly-compatible versions are usually sold with a "-POLY" suffix in the part number, and they're wired for Poly and Polycom phones — a cable made for a Cisco or Avaya phone won't work here even though the QD connector is identical. If you're buying a corded headset for an Edge phone, buy the Poly-specific bundle rather than a generic headset plus whichever cable you have spare.Corded options
EncorePro HW510 — mono, over-the-head
The standard entry-level corded option: one ear covered, a noise-cancelling microphone rated to block a large share of background noise, and foam ear cushions. The Quick Disconnect lets you step away from the desk without removing the headset or unplugging anything.
EncorePro HW540 — convertible, three wearing styles
The same audio as the HW510 but convertible — over-the-head, over-the-ear, or behind-the-neck from one headset. Worth the difference if you're kitting shared desks or a team with mixed preferences. Connects through the Edge's RJ9 port and dedicated headset key.
Our EncorePro series review compares the full corded range if you want to weigh the models against each other.
For very loud environments
For factory floors, airports, and similar, Plantronics makes an industrial-grade dual-ear headset with oversized ear cups that block a substantial amount of ambient noise through physical isolation. It uses the standard QD connector with the appropriate adapter for the Edge.
USB-C corded options
Because the Edge E has USB-C ports, a USB headset can plug straight into the phone:
- Blackwire 5210 — over-the-head mono with a noise-cancelling microphone and leatherette cushions. The USB-C and 3.5mm combination means the same headset also works with tablets, laptops, and phones with a headphone jack.
- Blackwire 8225 — the step up, with Digital Hybrid Active Noise Cancelling at adjustable levels, a built-in busylight, and an Acoustic Fence boom arm — the same microphone technology in the Edge phone itself.
Wireless options
Poly CS540 with EHS — the standard choice
The CS540 is convertible (over-the-head or over-the-ear), runs on DECT with up to 350 feet of range, and paired with the right EHS adapter gives full remote answer and end from the headset on an Edge phone. For most desk-phone-only setups, this is the one.
Poly Savi — for multiple devices
If you also need a computer and a mobile device on the same headset, the Savi range adds that. The current models are the Savi 7310/7320 (desk phone and computer) and the Savi 8410/8420/8445 (desk phone, computer, and Bluetooth mobile, with ANC and telecoil hearing-aid compatibility on some models).
If you're working from an older list, note the Savi 7210 and Savi 8220 have been replaced by the 7310 and 8420 respectively. Our Savi 8400 comparison covers the current range.
Poly Voyager 5200 — Bluetooth
A discreet over-the-ear Bluetooth headset with WindSmart technology for outdoor use. On Edge models with Bluetooth 5.0 built in, it pairs directly to the phone; on models without, the included BT700 Class 1 dongle handles the connection. Because it's Bluetooth, it also pairs to your mobile and leaves the office with you.
Which should you choose?
Three questions settle it:
- Do you need to leave your desk during calls? If not, corded via RJ9 or USB-C is simpler and cheaper. If yes, wireless with EHS.
- Do you also take calls on a computer? If yes, a Savi model or a USB headset that serves both. If it's desk phone only, the CS540.
- How loud is your environment? Noise-cancelling microphone as the baseline, ANC or industrial isolation if the room is genuinely difficult.
What headsets work with a Poly Edge phone?
Most professional headsets do, because the Edge supports four connection types: RJ9 with a headset key, USB-C (two ports on the E series), 3.5mm, and EHS for wireless. Some E-series models also have Bluetooth 5.0 for direct pairing. Corded QD headsets need a Poly-specific bottom cable.
Do Edge B series phones support the same headsets as the E series?
Largely yes. The B10, B20, and B30 have a 3.5mm jack, an RJ9 port, and EHS support, so corded and wireless headsets work the same way. The E series adds USB-C ports and, on some models, built-in Bluetooth.
Can I plug a USB headset directly into a Poly Edge phone?
On the E series, yes — it has two USB-C ports, one on the back and one on the right side. Plug in a USB-C headset and the phone recognises it as a corded headset, with no adapter or dongle needed.
Do I need an EHS adapter for a wireless headset on a Poly Edge?
For remote answering, yes. EHS lets you answer and end calls from the headset while away from your desk. Without it, the headset still works but you have to be at the phone to pick up. Buy the EHS bundle rather than the headset alone.
Can I pair a Bluetooth headset directly to a Poly Edge phone?
On E-series models with Bluetooth 5.0 built in, yes — pair it as you would to any Bluetooth device. On models without, use a Class 1 USB dongle such as the BT700 in one of the USB-C ports.
The Edge series gives you more connection options than most desk phones, so the decision is really about how you work rather than what the phone supports. Call our team at 877-999-3838 with your exact Edge model and we'll confirm the right headset and cable.
