How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a dedicated desk-phone headset that keeps your hands free on real calls all day, choose Plantronics CS540; if you need a wireless gaming headset for PC and console play, choose Corsair HS35.
• Plantronics CS540 — biggest strength: A DECT 6.0 wireless office system with an HL10 handset lifter, so you can answer and end desk-phone calls remotely without touching the phone.
• Plantronics CS540 — biggest trade-off: It's built around a traditional phone line or IP phone setup, not gaming or general media listening.
• Corsair HS35 — biggest strength: Tri-mode wireless gaming audio with Dolby Atmos on PC and up to 30 hours of battery life.
• Corsair HS35 — biggest trade-off: Dolby Atmos only works on PC, and there's no active noise cancellation.
• Pick the Plantronics CS540 if your day revolves around phone calls at a desk.
• Pick the Corsair HS35 if your day revolves around games, chat, and streaming on PC or console.
The CS540 is an office headset through and through. Its wireless technology is DECT 6.0, which is the standard for cordless desk-phone systems, and it runs on a 1.9 GHz frequency range. That combination is about stable, dedicated wireless for voice calls rather than Bluetooth pairing to whatever device is nearby. The package includes the HL10 handset lifter, which physically lifts your phone's handset off the cradle when a call comes in and returns it when you're done. If you've ever wished you could answer your desk phone from across the room, that's exactly what this is designed to do.
The design leans toward all-day wearability. It's an on-ear, around-the-ear convertible headset with a plastic body in black, and the marketing describes it as the lightest DECT headset in its class. You get a charging base, a headband, and a fit kit with extra ear loops and ear tips, so you can wear it over the head or convert it to an earhook depending on what feels better over a long shift. The battery is rated at 7 hours of talk time with an adaptive power system that conserves charge. There's also wideband audio and a noise-canceling microphone, plus active noise cancellation and touch controls for answering and ending calls.
Who should buy it? Anyone whose job is phone-based: receptionists, sales reps, support agents, front-desk staff, or anyone tethered to a desk phone who wants to stand up, grab a file, and keep talking. The 7-hour battery covers a normal workday of calls, and the lifter means you're not sprinting back to your desk every time the phone rings.
Who should skip it? If you want one headset for gaming, music, and video calls on a laptop, this isn't that product. The CS540 is optimized for telephony, and its wireless is DECT rather than Bluetooth, so it's not the flexible everyday audio device a gamer or general listener would want.
The HS35 v3 is a wireless gaming headset first. It uses 50 mm custom drivers with a 20 Hz to 20,000 Hz frequency response, 32 ohm impedance, and 117 dB sensitivity. It connects wirelessly over Bluetooth 5.3 and Wi-Fi, and the package includes a wireless USB receiver plus a detachable omnidirectional microphone and a 1.8 m USB charging cable. It's an over-ear design with round earcups, a plastic body in carbon, and it weighs 8.8 ounces — light enough that Corsair positions it around marathon sessions rather than quick calls.
The headline feature is Dolby Atmos spatial audio, which gives you directional cues so you can place footsteps, explosions, and movement around you. One important caveat straight from the specs: Dolby Atmos is available on PC only and requires the Dolby Access app. So the immersive spatial audio story is a PC story. Elsewhere, you're still getting solid wireless gaming audio, just without that layer.
Comfort is the other pillar. Corsair uses an adjustable floating headband and soft fabric earpads, which is a design meant to reduce pressure over long play sessions. The detachable omnidirectional mic handles voice chat, and earcup controls let you adjust volume and mute the mic without leaving the game. Battery life is rated up to 30 hours at 50% volume — more than a full day of gaming. The Bluetooth range is listed at 6 feet, which is worth noting: this is a headset you wear near your setup, not one you wander the house with.
Who should buy it? PC and console gamers who want one wireless headset for play and party chat, people who value long battery life, and anyone who wants a detachable mic and comfortable fabric pads for long sessions. It's also a reasonable pick for casual listening on PC, PlayStation, Switch, Mac, or mobile thanks to the tri-mode connectivity.
Who should skip it? If your main job is answering a desk phone all day, the HS35 doesn't have a handset lifter or DECT telephony wireless, and its noise control is listed as none. It's a gaming headset, not an office phone system.
• Best for desk-phone calling → Plantronics CS540. DECT 6.0 wireless plus the HL10 lifter is purpose-built for answering and ending landline or IP phone calls remotely.
• Best for battery life → Corsair HS35. Up to 30 hours versus 7 hours of talk time. If you hate charging, Corsair wins on paper.
• Best for all-day voice work → Plantronics CS540. Convertible on-ear fit, a fit kit with extra ear loops and tips, and an adaptive power system designed around a workday of calls.
• Best for gaming and spatial audio → Corsair HS35. 50 mm drivers and Dolby Atmos (PC only) are aimed squarely at games, not phone calls.
• Best for immersive PC play → Corsair HS35, as long as you're on PC and install the Dolby Access app.
• Best for hands-free answering → Plantronics CS540. The HL10 physically lifts and returns the handset, which no gaming headset does.
• Best for a detachable mic and earcup controls → Corsair HS35. Mute and volume are right on the earcup.
• Best for roaming while you talk → Plantronics CS540. Its whole pitch is cordless freedom around your workspace, whereas the HS35 lists a 6-foot Bluetooth range.
In my opinion, these two aren't really competing for the same buyer, and that's the point. If I worked a phone-based job, I'd buy the Plantronics CS540 — the HL10 lifter, DECT 6.0 wireless, and 7 hours of talk time are exactly what a desk-phone workflow needs. If I gamed on PC or console, I'd buy the Corsair HS35 for the 30-hour battery, Dolby Atmos on PC, and comfortable fabric earpads. Decide which of those two lives is yours, and the choice makes itself.
how to wireless headset
A wireless headset connects to your device without a cable, usually over Bluetooth, a USB receiver, or a dedicated wireless standard. The Corsair HS35 uses Bluetooth 5.3 and Wi-Fi with an included USB receiver, while the Plantronics CS540 uses DECT 6.0 for desk-phone wireless. Pair or plug in the receiver, then power on the headset.
how to connect wireless headset ps5
The Corsair HS35 lists PS5 among its supported platforms, so you can connect it via its wireless USB receiver or Bluetooth. Plug the receiver into the console or pair over Bluetooth, then select the headset as your audio output. The Plantronics CS540 is a desk-phone system, not a PS5 headset.
how to connect wireless headset xbox
Neither data sheet lists Xbox as a supported platform. The Corsair HS35 names PC, PS5, PS4, Switch, Mac, and mobile, while the Plantronics CS540 is built for traditional phone lines and IP telephony. If Xbox is your priority, check a headset that explicitly supports it.
how to work wireless headset
For work calls, the Plantronics CS540 is the fit: DECT 6.0 wireless, a noise-canceling mic, wideband audio, and the HL10 lifter for remote answer and end. The Corsair HS35 can handle voice chat and casual calls over Bluetooth, but it's designed for gaming rather than desk-phone work.
