How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight, foldable headset with adjustable RGB and a wired 3.5mm fallback for marathon PC and PlayStation sessions, choose ATTACK SHARK L90; if you need a headset built around a 40-hour battery, USB and Type-C lossless audio, and app-based control for Xbox Series X|S as well as PC and PlayStation, choose Redpepper 2.4GHz.
• ATTACK SHARK L90 — biggest strength: Weighs just 215 g, folds down for travel, and gives you three ways to connect: 2.4GHz via the included receiver, Bluetooth, and a 3.5 mm wired jack.
• ATTACK SHARK L90 — biggest trade-off: No published battery figure and no noise control, so long wireless sessions come with more planning and more ambient noise leaking in.
• Redpepper 2.4GHz — biggest strength: A stated 40-hour battery life on a 2-hour charge, plus 2.4GHz USB and Type-C lossless audio with a wired option as backup.
• Redpepper 2.4GHz — biggest trade-off: Heavier plastic build, no fold-flat design mentioned, and control that runs through an app rather than on-ear buttons.
• Who the L90 is for: Players who want the lightest possible headset, RGB flair, and flexible connectivity across PC, PS4 and PS5.
• Who the Redpepper is for: Players who hate charging mid-session and want a broad console spread, including Xbox Series X|S.
The L90 is the headset you buy when comfort and portability matter more than anything else. At 215 g, it sits at the light end of over-ear gaming headsets, and the fabric enclosure keeps it breathable during long stretches. The adjustable headband and foldable frame mean it collapses into a bag without much fuss — genuinely useful if you split your gaming between a desk, a couch and a friend's place.
Connectivity is where this headset earns its keep. You get 2.4GHz through the bundled receiver for near-instant response, Bluetooth for phone or tablet use, and a 3.5 mm wired jack as a zero-latency fallback for anything with a headphone port. Switching to Bluetooth is a double-press of the "M" button, and pairing shows up as "L90" in your device list. The 40 mm dynamic drivers cover a 20 Hz–20,000 Hz range, and the quoted 20 ms latency in wireless mode is low enough that lip-sync and gunfire cues should stay tight. 7.1 surround sound and software support round out the gaming side, with RGB backlighting if you like your setup to glow.
The mic is noise-canceling, and controls are handled remotely rather than on the cup. That's a design choice worth knowing before you buy.
Buy the L90 if you want the lightest, most packable option here, you value the wired jack as a safety net, and your main platforms are PC, PS4 and PS5. Skip it if you need a published battery number to plan around, you want active noise cancellation, or you'd rather tap buttons on the headset than reach for a remote control. The L90 also has no listed warranty, so factor that into how rough you are with your gear.
The Redpepper is the practical pick — the headset that gets out of your way and stays there. The headline figure is 40 hours of average battery life on a 2-hour charge, which is the kind of number that turns "I'll charge it later" into a once-a-week habit rather than a nightly one. For anyone who has ever had a wireless headset die mid-match, that single spec changes the whole ownership experience.
Audio comes through 2.4GHz USB and Type-C for lossless transmission, which means it works with PC, PS4, PS5 and — notably — Xbox Series X|S, a platform a lot of wireless headsets skip. A wired connection is supported too, so you're not stranded if the battery runs flat. The 40 mm dynamic drivers cover the same 20 Hz–20,000 Hz range as the L90, and you get 7.1 surround sound plus a noise-canceling mic and LED lighting. Bluetooth 5.3 is the newest standard in this comparison and gives you a cleaner, more efficient wireless link for phone and tablet duty.
Control runs through an app, which is a genuine advantage if you like tuning EQ profiles or checking battery status from your phone — and a mild annoyance if you'd rather not install anything. The enclosure is plastic, so it's built for function rather than premium feel, and the audience is listed as teens and adults, which fits a headset aimed at regular daily use.
Buy the Redpepper if battery anxiety is your main gripe, you game on Xbox Series X|S alongside PC or PlayStation, or you want app-level control and the latest Bluetooth version. Skip it if you need the lightest, most foldable headset possible, or you'd prefer physical on-ear controls over a companion app.
• Best for battery life → Redpepper 2.4GHz. 40 hours on a 2-hour charge versus no published figure for the L90.
• Best for lightweight comfort → ATTACK SHARK L90. 215 g with fabric earcups and an adjustable headband.
• Best for portability → ATTACK SHARK L90. The foldable frame is the only fold-flat design in this matchup.
• Best for console coverage → Redpepper 2.4GHz. It explicitly supports Xbox Series X|S in addition to PC, PS4 and PS5.
• Best for wired backup → Tie. Both offer a 3.5 mm jack, though the L90's triple-mode setup makes it the more flexible all-rounder.
• Best for latency-sensitive play → ATTACK SHARK L90. The 20 ms wireless latency figure is stated plainly; the Redpepper's 2.4GHz link is described as lossless but carries no latency number.
• Best for app-based tuning → Redpepper 2.4GHz. Control is handled through an app rather than a remote.
• Best for the newest Bluetooth → Redpepper 2.4GHz. Bluetooth 5.3 versus Bluetooth 4 on the L90.
If I were buying for myself, I'd take the Redpepper 2.4GHz. In my opinion, a stated 40-hour battery plus USB and Type-C lossless audio across PC, PS4, PS5 and Xbox Series X|S solves the two problems that actually ruin gaming sessions: dead batteries and platform lockout. The L90 wins on weight and portability, and I'd recommend it without hesitation to anyone who travels with their headset or wants the wired jack as their primary connection. But for a desk-bound setup that just needs to work every night, the Redpepper is the safer call.
Not universally. The L90 is better on weight (215 g), portability and stated latency (20 ms), while the Redpepper is better on battery life (40 hours), Bluetooth version (5.3) and Xbox Series X|S support. Which is "better" depends entirely on which of those you care about.
The listed average battery life is 40 hours, with a 2-hour charge time. Real-world results will vary with volume, LED lighting and whether you're on 2.4GHz or Bluetooth, but 40 hours is the manufacturer's figure.
The data sheet lists compatibility with PS4, PS5 and PC, so I would not count on Xbox support. If Xbox Series X|S matters to you, the Redpepper explicitly includes it.
Both support a 3.5 mm wired connection, so either works. The L90 goes further with three modes — 2.4GHz, Bluetooth and wired — while the Redpepper pairs its 2.4GHz USB/Type-C link with a wired fallback. Since neither page shows a price here, check the current price on Amazon before deciding.
