Plantronics SSP 2715-01 SupraPlus Dual-Microphone Headset
The Plantronics SSP 2715-01 covers two lines
On a trading desk, in an interpretation booth, or at a dispatch position, one person sometimes has to stay live on two separate lines at the same time — speaking on one while listening to the other, with neither call bleeding into the wrong ear. The Plantronics SSP 2715-01 SupraPlus Dual-Microphone Headset is the unusual piece of hardware built for exactly that.
It's two complete monaural headsets — two earpieces, two microphones, two audio channels — mounted on a single headband. Each side runs entirely on its own, so one ear and mic can sit on Line A while the other handles Line B. That's a different tool from any ordinary headset, and the product name hides what it actually does.
Why the SSP 2715-01 has two separate microphones
The Plantronics SSP 2715-01 carries two independent noise-canceling microphones and two separate audio processors because each side connects to its own line — not because the two mics cooperate to cancel more noise. One microphone transmits to the first call; the other transmits to the second. The earpieces match: left ear on one channel, right ear on the other, kept apart end to end.
Two mics, two earpieces, two audio processors, on one headband. One operator talks and listens on two independent calls or systems at the same time, each fully separate.
Two earpieces but a single mic and a single audio source. Both ears hear the same call. It shuts out the room for one conversation — it can't bridge two.
Each side is its own headset — connect them separately
Because the two channels are independent, each Quick Disconnect needs its own connection. Plan one per side; they can match or mix.
- Desk phone, per line. A Plantronics QD audio processor — an M22-class amplifier or the current MDA524 — sits between each earpiece and its phone line. Two lines, two amplifiers.
- Computer or softphone, per line. A Plantronics USB-to-QD adapter (DA-series) connects a channel to a PC, for when one or both "lines" are softphones.
- One of each. Nothing requires both channels to go to the same kind of system — run one side into a desk phone and the other into a softphone if that's how the role works.
The Quick Disconnect on each side fits every Plantronics audio processor and USB-to-headset adapter, all sold separately.
Noise-canceling on both channels
Each microphone is a noise-canceling boom, so whichever line you're speaking on, the SSP 2715-01 keeps the room out of your transmission. On the busy floors where this headset belongs — trading desks, ops rooms — there's plenty of room noise to keep out.
Wideband clarity where the line supports it
Both channels carry wideband audio, which widens the voice band for more natural, more intelligible speech and fewer "say that again" moments across a long shift. Per Plantronics' spec, the wideband benefit needs a wideband-enabled phone on that line; on a standard line, each channel still delivers clean narrowband audio.
Built for all-day, two-line shifts
The SSP 2715-01 is built on Plantronics' SupraPlus HW251N — the lightweight frame trusted across contact centers — doubled up. Covering both ears runs warmer and a little heavier than a single monaural headset, which is the honest trade for locking onto two lines at once. The foam cushions are user-replaceable when they flatten with use.
There's no software trick that puts one person physically on two live lines at once, and consumer headsets don't attempt it. The SSP 2715-01 is a specialist's tool — narrow in purpose, exact in what it does. If your desk runs two lines and one person has to own both, this is the headset that turns two jobs into one motion.

Software. The SSP 2715-01 carries no Microsoft Teams or Zoom certification and needs no drivers of its own. When a channel connects through a Plantronics DA-series USB adapter, that side presents to the computer as a standard headset and works with softphones and UC clients the adapter supports.
Hardware. Each Quick Disconnect connects to a Plantronics audio processor for a desk phone (M22-class or the current MDA524) or a USB-to-QD adapter for a computer. A complete two-line setup uses two of these, one per channel — they can be the same type or one of each.
Platforms. The SSP 2715-01 is built for dual-line and dual-system telephony — trading and dealer desks, language interpretation, and dispatch or supervisory positions where one operator must stay live on two calls or two systems at the same time.
FAQ
Frequently Asked Questions
The Plantronics SSP 2715-01 lets one person work two separate phone lines or systems at the same time. It's two monaural headsets on one headband, each with its own mic, earpiece, and audio channel — used on trading desks, in interpretation, and at dispatch positions where an operator has to talk and listen on two calls at once.
No. The two microphones on the Plantronics SSP 2715-01 aren't combined for noise cancellation — each one serves its own independent line. If you only work a single line and want strong noise rejection, a single SupraPlus HW251N is the better and cheaper choice. The SSP 2715-01 is specifically for running two lines simultaneously.
The SSP 2715-01 ships as the headset only. Each of its two channels needs its own connection — a Plantronics QD audio processor for a desk phone, or a USB-to-QD adapter for a computer — both sold separately. A full two-line station therefore needs two adapters plus the headset.
A binaural headset has two earpieces but one microphone and one audio source, so both ears hear the same call. The SSP 2715-01 has two of everything — two mics, two earpieces, two audio processors — wired as two independent channels, so it can bridge two separate lines that a binaural headset can't.
Yes. Connect a channel through a Plantronics DA-series USB-to-QD adapter and that side works with computer softphones. You can run one channel to a softphone and the other to a desk phone if the role calls for it.
Yes — both channels of the SSP 2715-01 carry wideband audio for clearer, more natural voice. The wideband improvement requires a wideband-enabled phone on that line; on a standard line, the channel still delivers clean narrowband sound.
