If you want a lightweight, retro-styled everyday Bluetooth headphone with long battery life and an app-based EQ, choose Mondo Freestyle Over-Ear; if you need true 7.1 surround sound for gaming with a low-latency 2.4GHz connection and a boom mic, choose ATTACK SHARK L90. That's the whole decision in one line, and everything below is just the reasoning behind it.
• Mondo Freestyle Over-Ear — biggest strength: 22 hours of playtime, a light 203 g build, and a 36mm dynamic driver tuned for deep bass with app-controlled EQ.
• Mondo Freestyle Over-Ear — biggest trade-off: No surround sound, no boom mic, no wired jack, and Bluetooth 4 with 150 ms of audio latency — it's a music-first headphone, not a gaming one.
• ATTACK SHARK L90 — biggest strength: 7.1 surround sound, a 20 ms low-latency mode, three connection types (2.4GHz, Bluetooth, wired 3.5mm), and a noise-canceling mic.
• ATTACK SHARK L90 — biggest trade-off: No advertised battery figure, no listed app, a plastic-and-fabric build at 215 g, and a shorter 3.5mm/2.4GHz workflow that assumes you're near a console or PC.
• Who the Mondo is for: commuters, students, and casual listeners who want one retro-looking wireless headphone for all-day music.
• Who the L90 is for: gamers on PS4, PS5, or PC who want directional surround sound and voice chat without spending on a separate mic.
Let's start with what the Mondo Freestyle actually is, because the name "Freestyle" throws people. It's not a gaming headset. It's a Bluetooth music headphone with a distinctly 80s-inspired design — the rotating volume and track sliders on each earcup are pulled straight from a DJ mixer, and the whole thing is built around that retro street-style idea. The 36mm dynamic driver is on the smaller side, but Mondo pairs it with a dual-driver tuning approach and an EQ in the MONDO app, so you can push the low end where you want it.
The spec that jumps out is the battery: 22 hours of average life off a 90-minute charge. For a commuter or a student who listens on the way to work or class and again on the way home, that's roughly a week between charges. The 203 g weight is genuinely light for an over-ear, and with a 10-meter Bluetooth range you can leave your phone on the desk and walk around the room.
Where it falls short is anything competitive. The frequency response tops out at 20 kHz, which is fine, but there's no surround processing of any kind, no microphone, and no 3.5mm jack — so if your battery dies, you're done. Bluetooth 4 with 150 ms of latency is also a real limitation for games and video: that gap between on-screen action and sound is noticeable. Skip the Mondo if you want positional audio in shooters, voice chat, or a wired fallback. Buy it if you want a comfortable, stylish, long-lasting music headphone and you're happy controlling everything from the app and the on-cup sliders.
The L90 is the opposite kind of product. It's a wireless gaming headphone that also happens to work as a normal headphone, and the surround sound angle is the headline: 7.1 surround sound decoding through a 40mm dynamic driver. For anyone playing on PS4, PS5, or PC, that's what turns footsteps, gunfire, and environmental cues into directional information instead of a flat stereo blob. If surround sound is the reason you're reading this comparison, this is the one that actually delivers it.
The connection story is the other big selling point. You get three paths: a 2.4GHz dongle for the lowest-latency wireless use, Bluetooth for phone and tablet listening, and a wired 3.5mm jack when you want zero wireless involved. The listed audio latency is 20 ms, which is dramatically lower than the Mondo's 150 ms — that's the difference between sound that feels synced and sound that feels slightly behind.
Side-by-Side: Which Should You Choose?
• Best for surround sound → ATTACK SHARK L90. It's the only one of the two with 7.1 surround sound listed at all.
• Best for low-latency gaming → ATTACK SHARK L90. 20 ms versus 150 ms is not a subtle difference when you're reacting to audio cues.
• Best for battery life → Mondo Freestyle Over-Ear. 22 hours is explicitly stated; the L90 has no advertised figure.
• Best for lightweight all-day wear → Mondo Freestyle Over-Ear. 203 g versus 215 g, plus a more lifestyle-oriented build.
• Best for voice chat → ATTACK SHARK L90. It has a noise-canceling mic; the Mondo has none.
• Best for connection flexibility → ATTACK SHARK L90. 2.4GHz, Bluetooth, and a 3.5mm wired jack, versus Bluetooth-only.
• Best for casual music and retro style → Mondo Freestyle Over-Ear. The mixer-inspired controls, app EQ, and 80s design are the point.
• Best for console and PC gamers → ATTACK SHARK L90. Wide compatibility with PS4, PS5, and PC is built into its design.
If surround sound is the feature you actually care about, I'd buy the ATTACK SHARK L90. It's the only one of the two that offers 7.1 surround sound, it's the only one with a mic, and its 20 ms latency is what you want for games and video. In my opinion, the Mondo Freestyle Over-Ear is the better headphone for music — lighter, longer-lasting, and more stylish — but it isn't a surround sound product at all. Pick based on the job, not the brand.
FAQ
how to get surround sound headphones
how to test surround sound headphones
Test them with content that has clear directional cues — a game with footsteps or a film with movement across the screen — and compare what you hear against plain stereo. On the L90, use the 2.4GHz connection rather than Bluetooth for the most accurate result, since its latency is listed at 20 ms.
how to fix surround sound headphones
Check the connection first: the L90 needs its 2.4GHz receiver plugged into your PC, console, or mobile device, and it auto-connects once powered on. If it doesn't connect, it shuts down after five minutes of inactivity, so power it back on and re-seat the dongle. Also confirm your game or system audio output is set to the headset.
how to make surround sound headphones
You can't make a non-surround headphone into a surround one through settings alone — the Mondo Freestyle Over-Ear has no surround feature in its specs. If surround sound is a requirement, buy a headset that ships with it, like the L90. If price is your deciding factor between the two, check the current price on Amazon using the button on this page.
