How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want studio-grade, wired-or-wireless reference listening with a huge frequency range in a light, foldable frame, choose AKG Pro Audio K371BT; if you need a multi-platform gaming headset with a detachable boom mic and marathon battery life, choose HyperX Cloud III S.
• AKG Pro Audio K371BT — biggest strength: 50mm drivers with a 5 Hz–40 kHz frequency range and a closed-back over-ear design, tuned for accuracy rather than effect.
• AKG Pro Audio K371BT — biggest trade-off: No microphone and no gaming-oriented features; it's built for listening and mixing, not for voice chat.
• HyperX Cloud III S — biggest strength: Up to 120 hours on 2.4GHz and up to 200 hours over Bluetooth, plus a detachable 10mm boom mic and broad platform support.
• HyperX Cloud III S — biggest trade-off: Its 20 Hz–20 kHz range and gaming-tuned sound are aimed at immersion and voice chat, not critical reference work.
• Pick the AKG if you're an artist, engineer, podcaster, editor or producer who wants one pair of accurate, portable headphones for studio and travel.
• Pick the HyperX if you game across PC, console, Switch, Mac and mobile and want a mic, long battery life and a rugged aluminum frame in one headset.
The K371BT is, at heart, a studio tool that happens to travel well. The spec sheet tells the story: 50mm dynamic drivers, pure oxygen-free copper voice coils, 32-ohm impedance, and a frequency response stretching from 5 Hz all the way to 40 kHz. That range is the headline. It means the AKG is designed to reproduce deep lows and very high highs without hyping any part of the spectrum, which is exactly what you want when you're making decisions about a mix rather than just enjoying one.
The other half of the story is portability and isolation. At 255 grams (the item listing rounds to 300 g with accessories), it's light for an over-ear model, and it folds. The over-ear, closed-back design with plush slow-retention foam pads is meant to seal out a noisy room, so it works on a plane, in a shared office, or in a bedroom studio. Bluetooth 5 with a 10-meter range and a 2-hour charge time giving up to 40 hours of playback means you can leave the cable at home. A 3.5mm jack is there when you want a wired connection, and passive noise cancellation does the rest — no batteries required for that.
Who should buy it: artists, engineers, podcasters, video editors and content producers who need balanced, detailed audio and a comfortable fit for long sessions, and who value being able to fold the thing up and toss it in a bag. Who should skip it: anyone who needs a microphone for calls or team chat, and anyone who wants virtual surround or console-specific features. There's no boom mic here, and the tuning is deliberately neutral rather than bass-forward. If your main job is talking while you play, this isn't the pair.
The Cloud III S is a do-everything gaming headset, and the spec sheet backs that up. You get two wireless paths: 2.4GHz for low-latency gameplay and Bluetooth for everything else, with USB-A and USB-C connectors included so it works across PC, PS5, PS4, Nintendo Switch, Mac, mobile and Bluetooth devices. That's a lot of ground covered by one headset.
Battery is the signature feature. HyperX rates it at up to 120 hours on 2.4GHz and up to 200 hours in Bluetooth mode — the kind of numbers that mean you charge it occasionally rather than constantly. The angled 53mm drivers are tuned to accent the dynamic sounds of gaming, and on PC you get DTS Spatial Audio with virtual 3D positioning to help place footsteps and gunfire. There's also a detachable 10mm boom mic with an LED mute indicator and a built-in mesh filter, plus on-board controls: a wireless mode selector, volume wheel, mute button and a multi-function button for media and call management.
Comfort and durability are clearly priorities. Memory foam in the headband and ear cushions, wrapped in leatherette, plus a flexible aluminum frame that's meant to survive travel and everyday wear. The earcup plates are magnetic and removable if you want to personalize the look. Who should buy it: gamers on multiple platforms who want a mic, long battery life and a sturdy build in a single headset. Who should skip it: anyone doing critical mixing or mastering, since a 20 Hz–20 kHz range and gaming-tuned drivers prioritize impact and immersion over flat accuracy — and anyone who wants a wired-only, no-fuss studio reference pair.
Side-by-Side: Which Should You Choose?
• Best for critical listening and mixing → AKG Pro Audio K371BT. The 5 Hz–40 kHz range and neutral reference tuning are built for judging audio, not just enjoying it.
• Best for battery life → HyperX Cloud III S. Up to 120 hours on 2.4GHz and up to 200 hours over Bluetooth dwarf the AKG's 40-hour figure.
• Best for multi-platform flexibility → HyperX Cloud III S. PC, PS5, PS4, Switch, Mac, mobile and Bluetooth, with both USB-A and USB-C connectors included.
• Best for commuting and travel → AKG Pro Audio K371BT. At 255 grams with a folding design and closed-back isolation, it packs down and blocks out noise.
• Best for long studio sessions → AKG Pro Audio K371BT. Light weight plus plush, slow-retention foam pads make extended wear easier.
• Best for durability in a bag → HyperX Cloud III S. The flexible aluminum frame is explicitly designed to shrug off travel and accidents.
• Best for a wired option → AKG Pro Audio K371BT. A 3.5mm jack is available when you want to skip wireless entirely.
In my opinion, the right pick comes down to one question: are you making audio or consuming it while talking? If you're producing — mixing, editing, podcasting, recording — I'd buy the AKG Pro Audio K371BT. Its 5 Hz–40 kHz range, 50mm drivers and closed-back, foldable, 255-gram design are exactly what a portable reference headphone should be, and the 40-hour battery covers a full week of work between charges.
If you're gaming across several platforms and need a mic, I'd buy the HyperX Cloud III S instead. The 120/200-hour battery, detachable boom mic, aluminum frame and wide device support make it the more complete one-device solution for play and chat. Neither is objectively better — they're aimed at different jobs, and I'd choose based on which job is yours.
It works for gaming in the sense that any accurate headphone does — you'll hear positional detail well thanks to the wide frequency range and closed-back isolation. But it has no microphone and no low-latency 2.4GHz mode, so for competitive play and team chat the HyperX Cloud III S is the more practical choice.
Yes. It includes a detachable 10mm boom mic with an LED mute indicator and a built-in mesh filter, designed for clear voice chat and calls. The AKG Pro Audio K371BT has no microphone at all, which is the single biggest functional difference between the two.
The HyperX Cloud III S, by a wide margin. It's rated for up to 120 hours on 2.4GHz and up to 200 hours over Bluetooth, while the AKG Pro Audio K371BT is rated for up to 40 hours with a 2-hour charge time. If you hate charging, that gap matters.
"In my opinion, value depends on your use. If you need a mic and multi-platform gaming support, the HyperX Cloud III S covers more ground in one purchase. If accuracy, portability and studio-grade listening are the point, the AKG Pro Audio K371BT earns its place. Check the current price on Amazon before deciding — the button on this page shows it."
