How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a music-first wireless headphone with adaptive noise cancellation, hi-res LDAC audio and marathon battery life, choose CMF BY NOTHING Headphone Pro Active; if you need a low-latency gaming headset with a detachable boom mic and virtual 7.1 surround, choose ATTACK SHARK L30.
• CMF BY NOTHING Headphone Pro Active — biggest strength: adaptive active noise cancellation rated up to 40 dB paired with LDAC and Hi-Res certified 40mm dynamic drivers, so it's built for music and movies first.
• CMF BY NOTHING Headphone Pro Active — biggest trade-off: it's a Bluetooth headphone at heart. There's no dedicated 2.4G low-latency dongle and no boom microphone, so competitive gaming chat and frame-perfect audio aren't its strong suit.
• ATTACK SHARK L30 — biggest strength: tri-mode connectivity (2.4G, Bluetooth, 3.5mm AUX) with 20ms low latency, 7.1 virtual surround and a detachable 360° AI noise-canceling mic.
• ATTACK SHARK L30 — biggest trade-off: its noise control is passive only. There's no active noise cancellation, so it relies on the earcup seal rather than electronics to block sound.
• Who each pick is for: the CMF is for commuters, travelers and music listeners who want quiet and long playtime; the ATTACK SHARK is for gamers who need low latency, voice chat and positional audio.
This is a wireless over-ear headphone designed around listening, not around a gaming rig. The headline spec is adaptive active noise cancellation rated up to 40 dB, with a one-touch Transparency Mode when you need to hear the world again. The 40mm nickel-plated dynamic drivers cover a 20 Hz to 40,000 Hz range and carry LDAC plus Hi-Res certification, which matters if you stream high-bitrate audio and want the headphone to keep up with it. A Bass & Treble slider, custom EQ and CMF Spatial Audio with Concert and Cinema modes live in the Nothing X app, so you can tune the sound rather than accept one fixed profile.
Battery is the other big story. CMF rates it at up to 100 hours of playback, or up to 50 hours with ANC on, and a five-minute top-up is quoted as good for about four hours of listening. You also get Bluetooth 5.4 with a 10-meter range, a 3.5mm jack for wired listening, Google Fast Pair and Microsoft Swift Pair, and support for iOS, Android, macOS and Windows. The frame is lightweight at 283 grams, with faux leather and memory foam earpads and a headband designed to sit comfortably over a cap. It ships with a cable, a protective case and a manual.
Buy it if you want one headphone for commuting, flights, focused work and long listening sessions, and you value active noise cancellation and battery life over a boom mic. Skip it if your main use is competitive gaming voice chat or you want a wired-first, zero-latency connection for a PC setup. In my opinion, this is the pick for the listener who wants quiet and endurance in one package.
The L30 is a gaming headset through and through. Its centerpiece is 7.1 virtual surround sound, which is meant to place footsteps, gunfire and other directional cues around you rather than just left and right. The 50mm biological diaphragm drivers cover a 20 Hz to 20,000 Hz range, and companion software lets you build and save your own EQ profiles and fine-tune the 7.1 channel settings. Dynamic RGB lighting in steady or gradient modes is a tap away, which is a nice touch if your desk setup is part of the fun.
Connectivity is where it separates itself from a normal wireless headphone. You get three routes: 2.4G with the included USB-A/USB-C dual dongle at a quoted 20ms latency, Bluetooth with up to 30 meters of range, and a 3.5mm AUX cable. That covers PC, consoles and mobile devices. The detachable mic uses 360° AI algorithms to isolate your voice, and the headset pairs protein leather earcups and breathable memory foam with a lightweight aluminum alloy frame. A 1100mAh battery is rated at up to 100 hours, with auto-shutdown after five minutes of inactivity in 2.4G mode and over-voltage protection for charging while you play.
Buy it if you play on PC or console, you talk to teammates, and you want positional audio plus a low-latency wireless option. Skip it if you mainly listen to music on planes or in noisy offices and want active noise cancellation — this headset only offers passive isolation through its earcups.
Side-by-Side: Which Should You Choose?
• Best for competitive gaming and voice chat → ATTACK SHARK L30. 7.1 virtual surround, a detachable AI noise-canceling mic and a 20ms 2.4G mode.
• Best for hi-res music streaming → CMF BY NOTHING Headphone Pro Active. LDAC, Hi-Res certification and a 20 Hz–40,000 Hz range.
• Best for multi-device flexibility → ATTACK SHARK L30. 2.4G, Bluetooth and 3.5mm AUX, with a dual USB-A/USB-C dongle and up to 30m Bluetooth range.
• Best for long trips and deep-work sessions → CMF BY NOTHING Headphone Pro Active. Up to 50 hours with ANC on and a five-minute charge quoted at roughly four hours of playback.
• Best for wired-only listening → CMF BY NOTHING Headphone Pro Active. Its 3.5mm jack lets you keep listening without Bluetooth.
• Best for desk setups and RGB styling → ATTACK SHARK L30. Dynamic RGB lighting and PC software with custom EQ and 7.1 tuning.
• Best for comfort over long sessions → both, for different reasons. The CMF leans on a 283g frame with memory foam and a cap-friendly headband; the L30 uses protein leather, breathable memory foam and a lightweight aluminum alloy frame.
If I were buying one of these for myself, I'd take the CMF BY NOTHING Headphone Pro Active — my listening is mostly music, podcasts and travel, and adaptive ANC plus LDAC and long battery life is exactly what that life needs. I'd switch to the ATTACK SHARK L30 the moment my priority became gaming: the 7.1 surround, detachable mic and 20ms 2.4G mode are things the CMF simply doesn't offer. These aren't rivals so much as different tools. Buy the CMF to block out the world and listen; buy the L30 to hear where the world is shooting from. Before deciding, check the current price on Amazon, since that's the one thing that can tip a close call.
FAQ
Yes, based on the specs. The CMF offers adaptive active noise cancellation rated up to 40 dB plus a Transparency Mode, while the L30 relies on passive isolation from its earcups. For flights, trains and open offices, the CMF is the stronger choice.
They're quoted very similarly. CMF rates up to 100 hours of playback or up to 50 hours with ANC on, plus a five-minute charge for about four hours of use. ATTACK SHARK rates up to 100 hours from a 1100mAh battery with auto-shutdown after five minutes idle in 2.4G mode.
It has built-in controls including voice assistant support and works for calls, but it doesn't have the detachable boom mic that the L30 provides. If clear team voice chat is your priority, the L30's 360° AI noise-canceling mic is the better fit.
