If you want a gaming-first headset with a boom mic, LED earcups and one-cable USB plug-and-play, choose BENGOO G9000; if you need a light, transparent, retro-styled wired headphone for music, travel and everyday listening, choose Koss CL/80.
• BENGOO G9000 — biggest strength: A complete gaming package in one unit — 40mm drivers, an omni-directional noise-cancelling boom mic, in-line volume and mic mute, and USB connectivity.
• BENGOO G9000 — biggest trade-off: It's a wired USB headset built around desk and console use, so it isn't the lightest, most portable option for listening on the move.
• Koss CL/80 — biggest strength: A featherweight, over-ear design with a clear transparent shell, a 3.5mm plug and a 6-foot cord that works with almost anything you already own.
• Koss CL/80 — biggest trade-off: There's no microphone and no in-line volume/mute for voice chat, so it's a listening headphone rather than a headset.
• Who each pick is for: BENGOO G9000 for gamers who need voice chat and immersive game audio; Koss CL/80 for listeners who want comfort, portability and a classic look.
The G9000 is designed from the ground up as a gaming headset. The spec sheet tells that story clearly: 40mm dynamic drivers, a frequency range of 15Hz–20KHz, and 120-ohm impedance. That impedance figure is worth pausing on — it's on the higher side, which typically means the headset wants a decent amount of power to reach its potential. Because it connects over USB rather than a 3.5mm jack, it draws that power from the device itself, which is likely why BENGOO went with USB instead of a standard analog plug. It's a sensible design choice for a headset meant to sit at a desk or plug into a console.
The feature list is where this thing earns its keep. You get an omni-directional microphone with a long flexible boom, so you can bend it toward your mouth and keep it out of the way when you're not talking. Mic sensitivity is listed at -38dB, and the mic carries its own noise-cancelling treatment — useful when you're in a voice channel and don't want your mechanical keyboard doing the talking. There's a rotary volume controller and a one-key mic mute built into the braided USB cable, which runs 49 inches. That's a genuinely practical length for a desk setup, and the anti-winding braided jacket means it won't turn into a knot in your bag.
Buy it if you want one headset that handles game audio, voice chat, and volume control without extra gear, and you're playing at a desk or console. Skip it if you mainly listen to music on the move, want something you can fold into a pocket, or need a standard 3.5mm plug for a phone or portable player without an adapter situation.
Koss CL/80: Who It's For
The CL/80 goes in a completely different direction, and the name says it: "Clear Retro 90s Style." The whole shell is transparent, from the headband to the cord, so you can literally see the drivers doing their work. It's a design statement as much as a headphone — and honestly, that's a big part of why someone buys it. It's not trying to disappear into a gaming rig; it's trying to look like something.
Under the clear plastic, the numbers are respectable for the category. The CL/80 uses 40mm dynamic drivers — same driver size class as the G9000 — with a wider stated frequency range of 16Hz–22,000Hz and a much lower 60-ohm impedance. Lower impedance generally means it's easier to drive from modest sources, which fits its role: a grab-and-go headphone you plug straight into a laptop, tablet, or handheld gaming device. Koss lists it at 101dB sensitivity, so it should reach reasonable volume without much effort from the source. The 3.5mm plug is the universal connector here, and the 6-foot cord gives you slack to move around a desk or couch.
Comfort is where Koss leans hard. The whole thing weighs 7.36 ounces, and the copy emphasizes "ultra lightweight" for travelers, musicians and listeners on the go. The cushions are plush leatherette, the headband is padded and adjustable, and the around-the-ear design is meant to sit securely while providing some noise isolation. Rounding it out: it's rated for kids, teens and adults, and it carries a limited lifetime warranty — a notably long coverage window for a wired headphone.
Buy it if you want a light, comfortable, plug-and-play headphone for music, movies, audiobooks and casual gaming on a laptop or phone, and you like the transparent retro look. Skip it if you need a microphone for voice chat, want in-line volume or mute controls, or you're specifically after a headset to pair with a console.
• Best for voice chat and multiplayer gaming → BENGOO G9000. It's the only one of the two with a boom microphone, mic mute, and in-line volume.
• Best for plug-and-play with almost any device → Koss CL/80. A 3.5mm jack works with phones, laptops, tablets and handhelds without adapters.
• Best for long desk or console sessions → BENGOO G9000. Memory foam protein-leather pads, an adjustable multi-point headband, and a 49-inch braided cable built for a stationary setup.
• Best for portability and light weight → Koss CL/80. At 7.36 ounces with a compact over-ear build, it's the one you toss in a bag.
• Best for a "fun" aesthetic → depends on your taste. LED earcups if you want gamer energy; a fully transparent shell if you want retro style.
• Best for easy driving from weak sources → Koss CL/80. Its 60-ohm impedance is friendlier to phones and tablets than the G9000's 120 ohms.
• Best for wider stated frequency range → Koss CL/80. 16Hz–22,000Hz versus the G9000's 15Hz–20,000Hz — close, but the Koss reaches higher.
• Longest warranty coverage → Koss CL/80. Limited lifetime warranty, versus BENGOO's 2-year warranty.
If I had to pick one for myself, I'd reach for the Koss CL/80. In my opinion, it fits more of my actual daily listening — music, video, casual laptop gaming — and the light weight, 3.5mm plug and lifetime warranty make it the lower-fuss ownership experience. That said, if gaming with voice chat is your main use, the BENGOO G9000 is the clear choice: the mic, in-line controls and USB connectivity simply aren't things the Koss offers. Match the tool to the job. Check the current price on Amazon for whichever one fits your setup before you commit.
FAQ
No. The CL/80 is a listening headphone, not a headset — its feature list covers audio, cushions and a 3.5mm connection, with no mic and no in-line mute. If you need to talk in-game or on calls, look at the BENGOO G9000 instead.
Yes — BENGOO lists compatibility with PC, laptop, tablet, iPad, computer and mobile phone, though it connects over USB rather than a 3.5mm jack. For an older Xbox One controller, the manufacturer notes you'll need an extra Microsoft Adapter that isn't included.
Both are built for extended use, but differently. The G9000 uses memory foam protein-leather earcups with an adjustable multi-point headband for desk sessions. The CL/80 is the lighter of the two at 7.36 ounces with plush leatherette cushions and a padded adjustable headband, which suits on-the-go listening.
