If you want virtual 7.1 surround sound with software-driven audio tuning, choose Edifier G2II; if you need a no-frills analog over-ear headset with a detachable boom mic and a sling headband, choose Koss GMR540-A-ISO.
• Edifier G2II — biggest strength: 50mm drivers paired with a 7.1 virtual surround sound engine and a full software suite (equalizer, environment effects, mic boost, magic voice). Biggest trade-off: it's a USB-only wired headset that leans on software to do its best work.
• Koss GMR540-A-ISO — biggest strength: a lightweight closed-back design with memory foam cushions, a sling headband, and a detachable boom mic with inline volume and mute. Biggest trade-off: analog 3.5mm only, no surround processing.
• Pick the Edifier G2II if you game on a desktop PC or Mac, want customizable virtual surround, and don't mind a USB tether.
• Pick the Koss GMR540-A-ISO if you want a simple plug-and-play over-ear headset for long sessions and value a lighter, more analog approach.
• In short: the Edifier is the feature-rich software play; the Koss is the lightweight, straightforward hardware play.
The G2II is built around a pair of 50mm dynamic drivers with a 20Hz–20kHz frequency range, and Edifier pairs that hardware with a 7.1 virtual surround engine. The pitch is directional awareness: gunfire, footsteps, and other positional cues presented in a 360-degree soundscape so you can better judge where things are happening. For competitive shooters where audio positioning matters, that's the core reason to consider it.
What separates it from a plain headset is the software. Edifier's companion app exposes a virtual 7.1 speaker shifter, a multi-band equalizer, environment effects, surround max, microphone echo, magic voice, and microphone boost. If you like tuning your audio per game — boosting lows for explosions, flattening the EQ for voice chat — that flexibility is the real draw. Honestly, that software layer is doing as much work as the drivers.
Who should buy it: PC and Mac gamers who want virtual surround, a customizable software suite, and a detachable noise-canceling mic in one package. Who should skip it: anyone who wants to plug straight into a console controller, phone, or handheld — this is a USB 2.0 wired headset with an 8.2ft cable, so portability and analog flexibility aren't its strengths.
Koss GMR540-A-ISO: Who It's For
The Koss GMR540-A-ISO takes the opposite approach. It's a closed-back, over-ear headset with dynamic 60-ohm drivers covering a 15Hz–22,000Hz range — a wider low-end reach on paper than the Edifier, which suits deep bass in shooters and cinematic RPGs. The closed-back enclosure is the key design choice: it isolates you from the room, so external noise stays out and you can stay locked into the game.
Comfort is clearly the headline here. Koss uses memory foam cushions and an ergonomic sling headband that spreads weight evenly across your head instead of concentrating it on a single pressure point. Combined with a lightweight build, the goal is fatigue-free sessions over hours, not minutes. If you've ever finished a long raid with a sore spot on your crown, this is the design detail that matters.
The mic is a detachable boom with inline volume control and a mute switch on the cable — simple, physical, and easy to manage without software. Connectivity is a standard 3.5mm jack, which means it works with anything that has a headphone port: consoles, controllers, handhelds, laptops, and desktops. No drivers, no app, no setup ritual. Koss also backs it with a limited lifetime warranty, which speaks to how the brand views the durability of the build.
Who should buy it: gamers who want a lightweight closed-back headset with strong isolation, physical controls, and universal 3.5mm compatibility. Who should skip it: anyone who specifically wants virtual surround processing, RGB lighting, or software EQ — none of that is here.
Side-by-Side: Which Should You Choose?
• Best for software customization → Edifier G2II. Equalizer, environment effects, mic boost, magic voice, and echo all live in Edifier's app.
• Best for plug-and-play simplicity → Koss GMR540-A-ISO. A 3.5mm jack and inline controls, nothing to install.
• Best for long-session comfort design → Koss GMR540-A-ISO. Memory foam cushions plus a sling headband built to redistribute weight.
• Best for noise isolation from your surroundings → Koss GMR540-A-ISO. The closed-back enclosure is designed to keep external sound out.
• Best for USB desktop setups → Edifier G2II. Its USB 2.0 connection and 8.2ft cable suit a fixed PC or Mac station.
• Best for use across consoles, handhelds, and controllers → Koss GMR540-A-ISO. The 3.5mm jack travels anywhere.
• Best for a detachable mic on both → a tie. Both ship with detachable boom mics, though the Edifier adds noise-canceling tech and the Koss adds an inline mute switch.
In my opinion, the Edifier G2II is the better pick if you game primarily at a PC or Mac desk and you actually want the 7.1 virtual surround and the software EQ — that's a feature set the Koss simply doesn't offer, and it's the reason to spend on the Edifier. But if I wanted one headset I could grab and plug into anything without thinking about drivers, I'd take the Koss GMR540-A-ISO: the closed-back isolation, memory foam, sling headband, and inline mute are exactly what I want for long, low-hassle sessions. Two different philosophies — pick the one that matches how you actually play.
what is over ear headset
An over-ear headset is one whose earcups surround your ears rather than resting on them, which usually means better isolation and less pressure on the ear itself. Both the Edifier G2II and the Koss GMR540-A-ISO are over-ear designs, with the Koss using memory foam cushions and the Edifier using leather earcups.
what is the best over ear headset
There's no single best — it depends on your setup and priorities. In my opinion, the Edifier G2II is the stronger choice for PC gamers who want virtual 7.1 surround and software tuning, while the Koss GMR540-A-ISO is the better fit for anyone who wants lightweight comfort, closed-back isolation, and simple 3.5mm plug-and-play.
what are over ear headsets
Over-ear headsets are headphones with full-size earcups that encircle the ear, often paired with a microphone for gaming or calls. The Edifier G2II adds a detachable noise-canceling mic and USB connectivity, while the Koss GMR540-A-ISO uses a detachable boom mic with inline volume and mute over a 3.5mm connection.
what is on ear headset
An on-ear headset rests on top of your ears instead of around them, which typically means less isolation and a different fit. Neither of these two is on-ear — both the Edifier G2II and the Koss GMR540-A-ISO are over-ear models, so if you specifically want on-ear, you'd be looking at a different category entirely.
