• Koss GMR545-A-AIR — biggest strength: an ultra lightweight open-back over-ear design with a sling headband, memory foam cushions and a detachable boom mic with its own volume control and mute switch.
• Koss GMR545-A-AIR — biggest trade-off: the open-back build lets outside sound in and doesn't isolate you from a noisy room, and it's a wired 3.5 mm headset only.
• BENGOO G9000 — biggest strength: a closed-back over-ear design with passive noise cancellation, a flexible noise-isolating mic and volume plus one-key mute on an inline control box on a braided cable.
• BENGOO G9000 — biggest trade-off: it's a heavier, warmer leather-pad headset with LED lighting, and connecting an older Xbox One controller needs an extra Microsoft adapter that isn't included.
• Pick Koss GMR545-A-AIR if you play long sessions and value comfort, open sound and clear mic control above isolation.
• Pick BENGOO G9000 if you want one headset for PS4, PC, laptop, tablet and phone, with passive isolation and a glowing look.
The GMR545-A-AIR is the headset Koss aimed at gamers who care most about comfort and an expansive sound. The pitch is straightforward: dynamic 60 ohm drivers covering 15–22,000 Hz for a wide, 3D-style audio field, an open-back over-ear design that lets sound pass through for a roomy feel, and an ultra lightweight frame that's meant to disappear on your head over a long session. That lightweight design is paired with soft memory foam cushions and a sling headband that spreads the weight evenly to cut down on pressure points.
What stands out to me is the control story. The detachable boom mic handles communication, and the headset gives you volume control plus a mute switch on a remote, so you can trim the level or kill the mic without digging through menus. The cable, 3.5 mm jack and wired connectivity keep things simple and lag-free. Koss backs it with a limited lifetime warranty and a black finish, which tells you this is a buy-once, keep-it-around product rather than a disposable one.
Who should buy it? In my opinion, this is the pick for someone who games for hours at a time, plays in a quiet room where they don't need to block out noise, and wants crisp mic control. It also suits players who like being able to hear what's happening around them — the open-back design is a feature, not a flaw, for that crowd. Who should skip it? If you game next to a noisy fan, a TV or other people, the open-back design won't seal you off, and if you want a headset that works across consoles and mobile, you'll want the more broadly compatible option below.
The G9000 is BENGOO's classic closed-back, over-ear gaming headset, and it's built around flexibility. It lists support for PlayStation 4, New Xbox One, PC, laptop, PSP, tablet, iPad, computer and mobile phone, with the one caveat that an older Xbox One controller needs an extra Microsoft adapter that isn't included. The audio comes from a high-precision 40 mm magnetic neodymium driver covering 20 Hz–20,000 Hz, tuned for a surrounding stereo subwoofer effect that BENGOO describes as a vivid, punchy sound field for shooters and open-world games.
Comfort and durability are the other themes. The protein over-ear pads are thick, breathable and skin-friendly leather, and the multi-point headband adjusts to different head sizes. Passive noise cancellation comes from the closed design and the thickened cushions, which also aim to reduce heat and sweat. There's LED lighting on the earcups for atmosphere, and the whole thing is wired through a 49-inch anti-winding braided cable.
The controls are the part that ties directly to the comparison angle: an inline control box gives you a rotary volume wheel and a one-key mic mute. The mic itself is omni-directional and flexible, so you can angle it where you want it, and it uses a noise-cancelling design to pick up your voice clearly. BENGOO covers it with a one-year warranty.
Who should buy it? This is for the gamer who wants one wired headset that works across several devices, wants to be sealed off from background noise, and likes a bit of RGB flair. Who should skip it? If you run hot or play marathon sessions, the leather pads and closed-back fit can trap heat — a real trade-off versus the Koss — and if you have an old Xbox One controller, budget for that adapter.
Side-by-Side: Which Should You Choose?
• Best for all-day comfort → Koss GMR545-A-AIR. The ultra lightweight build, sling headband and memory foam cushions are all aimed at reducing pressure and fatigue over long sessions.
• Best for isolation from noise → BENGOO G9000. Passive noise cancellation, closed-back earcups and thickened leather pads seal you off from a busy room.
• Best for volume control on the fly → BENGOO G9000. The inline rotary wheel plus one-key mute on the control box makes level and mic changes genuinely effortless.
• Best for device flexibility → BENGOO G9000. It covers PS4, New Xbox One, PC, laptop, tablet, iPad, PSP and phones, with the noted adapter caveat for older Xbox One controllers.
• Best for open, spacious sound → Koss GMR545-A-AIR. The open-back design plus 15–22,000 Hz dynamic 60 ohm drivers is built for an expansive, hear-through experience.
• Best for punchy, bass-forward gaming audio → BENGOO G9000. The 40 mm neodymium driver and surrounding stereo subwoofer tuning target vivid, shock-feeling sound.
• Best for longevity of ownership → Koss GMR545-A-AIR. A limited lifetime warranty is a strong statement about how long Koss expects this headset to last.
If I had to pick one, I'd take the Koss GMR545-A-AIR. For me, long sessions are the norm, and the combination of an ultra lightweight open-back build, memory foam cushions, a pressure-reducing sling headband and a detachable mic with its own volume and mute control is exactly what I want at a desk. The limited lifetime warranty seals it. I'd only switch to the BENGOO G9000 if I needed one headset for many devices, wanted to block out a noisy room, or preferred closed-back isolation and a bass-heavy, LED-lit look. Both are wired 3.5 mm headsets, so check the current price on Amazon before you decide.
For me, the Koss. Its ultra lightweight design, sling headband and memory foam cushions are specifically built to spread weight and reduce pressure points, and the open-back build runs cooler. The G9000's closed leather pads insulate more but can trap heat.
Both handle volume well, just differently. The Koss uses a remote with volume control plus a mute switch alongside a detachable boom mic. The BENGOO uses an inline control box with a rotary volume wheel and one-key mic mute on a braided cable.
Yes — BENGOO lists PS4, New Xbox One, PC, laptop, PSP, tablet, iPad, computer and mobile phone support. The one catch: an older Xbox One controller needs an extra Microsoft adapter, which isn't included.
Yes, and it's the biggest split here. The Koss GMR545-A-AIR is open-back, so sound passes through for an expansive feel but you also hear your room. The BENGOO G9000 is closed-back with passive noise cancellation, which blocks more outside noise but can feel warmer.
