Plantronics CS361N Supraplus Wireless Headset System
The CS361N combines DECT 6.0 wireless technology with our convertible Supraplus headset design, giving you freedom to move up to 350 feet from your desk phone while maintaining HD voice clarity. We built this system for contact centers, offices, and any environment where you need hands-free mobility without sacrificing call quality.
With three wearing styles in one headset—over-the-head, over-the-ear, or behind-the-neck—you choose the configuration that fits your workday. The HL10 handset lifter sold separately enables remote answer/end capability, so you control calls even when you're away from your desk.
What makes the CS361N stand out
DECT 6.0 wireless technology and range
The CS361N operates on DECT 6.0, a dedicated frequency band separate from Wi-Fi and Bluetooth. This eliminates the dropped-call frustration common in crowded office environments where dozens of devices compete for the same 2.4 GHz spectrum.
You get reliable wireless coverage up to 350 feet line-of-sight from the base station, enough range to move between conference rooms, file areas, and break rooms while staying connected. The base automatically pairs with the headset out of the box—no IT configuration required. A single subscription base supports one headset, and you can deploy multiple CS361N systems in the same office without cross-talk or pairing conflicts.
Convertible wearing styles for all-day comfort
We include three wearing configurations in every CS361N package: over-the-head with a soft padded headband, over-the-ear with a stabilizing ear loop, and behind-the-neck for users who prefer their hair or headwear unobstructed. You swap between styles in seconds without tools.
The headset weighs just over one ounce, light enough that most users forget they’re wearing it after the first hour. Foam ear cushions distribute pressure evenly, and the flexible boom arm positions the noise-canceling microphone exactly where you need it. For contact-center teams on eight-hour shifts or sales reps who live on the phone, this flexibility prevents the fatigue that comes from a one-size-fits-all design.
###Noise-canceling microphone performance### The Supraplus boom incorporates a unidirectional noise-canceling microphone tuned to capture your voice while suppressing ambient office noise—keyboard clatter, nearby conversations, HVAC hum. Callers on the other end hear you clearly even when your workspace isn't quiet. Wideband audio extends frequency response beyond standard telephony, preserving the natural tone of your voice. This matters for roles where tone conveys as much as words—sales calls, customer service, client consultations. The microphone boom rotates 300 degrees and locks into position, so you set it once and it stays put through an entire shift.

Common questions about the CS361N headset system
The CS361N is designed for analog desk phones with a standard modular telephone jack. If your VoIP phone has an analog handset port, the headset will connect and function normally.
For IP phones that lack analog ports, you'll need a compatible electronic hook switch cable instead of the standard telephone cord. Check with our support team or your phone manufacturer to confirm compatibility before purchasing.
Yes. Each CS361N base and headset pair on a unique DECT channel, so you can deploy dozens of systems in the same workspace without cross-talk or pairing conflicts.
DECT 6.0 automatically selects the clearest available channel when you power on the base, and each subscription supports one headset. There's no master controller or IT configuration required.
Both are DECT 6.0 wireless headsets with similar range and audio quality. The CS361N uses the convertible Supraplus design with three wearing styles—over-the-head, over-the-ear, or behind-the-neck—in one package.
The CS540 is a dedicated over-the-ear monaural headset with an adaptive power system that extends range in open environments. If you know you prefer over-the-ear only, the CS540 is lighter and slightly more compact. If you want flexibility to switch styles, the CS361N is the better choice.
Remote answer/end requires the HL10 handset lifter accessory, sold separately. The lifter mounts to your desk phone with an adhesive pad and connects to the headset base via a short cable.
When you press the call button on your headset, the lifter mechanically raises your phone's handset, triggering the call to connect. Press again to end the call and the lifter lowers the handset. Installation takes less than a minute and works with most desk phone models.
Yes. The battery compartment is accessible without tools—slide the cover off the headset ear speaker, remove the old battery, and snap in a replacement.
Replacement batteries are available from our store or authorized dealers. We recommend keeping a spare on hand for zero-downtime swaps if you're in a mission-critical role.
The CS361N delivers up to 350 feet line-of-sight range from the base station. In real-world office environments with walls, furniture, and other obstacles, expect 100 to 200 feet of reliable coverage depending on building materials.
Concrete and metal reduce range more than drywall and glass. Most users can move freely within a standard office suite, between adjacent conference rooms, or down a hallway without dropping calls.
The unidirectional noise-canceling microphone significantly reduces background noise from keyboards, nearby conversations, and HVAC systems. It won't eliminate every sound—if someone is shouting directly behind you, the mic will pick up some of it—but callers consistently report clearer audio compared to standard omni-directional mics.
For the best results, position the microphone boom about a finger's width from the corner of your mouth and ensure the foam windscreen is in place.
