• Razer Kaira X — biggest strength: Triforce titanium 50mm drivers plus a bendable HyperClear cardioid mic and a 3.5mm jack that works across Xbox, PC, Mac and mobile. Biggest trade-off: it's wired and over-ear, so it's tethered to your device and less portable.
• CMF BY NOTHING Buds Pro 2 — biggest strength: 50dB adaptive hybrid ANC, LDAC hi-res audio, a smart dial case and 43 hours of total playtime. Biggest trade-off: in-ear buds with no boom mic, so voice pickup depends on the six onboard mics rather than a mic you can position.
• Pick Razer Kaira X if you mainly game at a desk or on a couch with an Xbox or PC and want a real mic and big over-ear cups.
• Pick CMF BY NOTHING Buds Pro 2 if you're on the move — commuting, running, working — and want noise cancelling in something that disappears into a pocket.
The Kaira X is a gaming-first headset, and its design choices make that obvious. The Triforce titanium 50mm drivers are tuned to handle highs, mids and lows separately, which Razer says produces brighter trebles and more powerful bass. That's a spec-level promise rather than something I can verify, but the architecture tells you the intent: a wide, lively sound for games and media rather than a flat studio reference.
The mic is the part that separates it from earbuds. The HyperClear cardioid pickup is bendable, housed to suppress noise from the back and sides, and paired with mic monitoring and game/chat balance. In practice that means you can position the mic near your mouth and control the mix between your teammates and your game audio — something no in-ear bud does as naturally. The Flowknit memory foam cushions use a breathable weave to cut sweat and heat, and Razer says a denser foam reduces clamping force, which matters if you wear a headset for long sessions. On-headset controls (a mute button and volume slider under the left earcup) keep you from alt-tabbing mid-match.
Connectivity is the other headline. It's a wired 3.5mm headset, officially licensed and developed alongside Xbox, and that same jack lets it work with PC, Mac and mobile devices. Note that Xbox One may need a Stereo Adapter sold separately. It also plays nicely with Windows Sonic for virtual surround. Weighing 1.2 pounds with a plastic oval over-ear frame in red, it's a desk-and-couch product, not a commute product.
CMF BY NOTHING Buds Pro 2: Who It's For
The Buds Pro 2 are the opposite philosophy: tiny, wireless and built to travel. The headline feature is 50dB adaptive hybrid ANC that automatically detects noise leakage between the bud and your ear canal to keep cancellation optimal, plus smart ambient recognition that keeps you aware during runs and lets you switch into transparency mode. If you commute on trains, work in a noisy office or run outdoors, that's the core value.
Audio is handled by a Dirac-tuned dual-driver setup: an 11mm ultra-bass driver plus a 6mm tweeter, with LDAC lossless transmission and Dynamic Bass Boost 2.0. Six HD mics with Clear Voice Technology 3.0 handle calls, and CMF claims triple the audio transmission rate of traditional earbuds alongside Hi-Res Audio support. Bluetooth 5.3 enables multipoint so you can stay connected to two devices at once, and 120ms low latency is aimed at mobile gaming.
The case is the clever bit. A smart dial on the case itself controls volume, tracks and noise modes, so you're not fishing for your phone. Battery is rated at 10 hours per charge and 43 hours total with the case, and a 10-minute quick charge gives 3 hours of playback. IP55 water resistance means sweat and a post-swim rinse are fine. The buds are in-ear with a 32 ohm impedance, and the orange case measures roughly 5.3 x 5.3 x 2.3 cm and weighs 46g — genuinely pocketable.
Buy it if you want wireless ANC earbuds for commuting, work, travel and workouts, with long battery life and hi-res codec support. Skip it if you need a boom mic for competitive chat, prefer over-ear comfort, or want a wired connection with no charging to think about.
• Best for gaming on Xbox or PC → Razer Kaira X. Official Xbox licensing, Windows Sonic support and a 3.5mm jack make it the native choice for console and desktop play.
• Best for noise cancelling → CMF BY NOTHING Buds Pro 2. 50dB adaptive hybrid ANC with ambient recognition is a feature the Kaira X simply doesn't have — its noise control is listed as none.
• Best for battery life → CMF BY NOTHING Buds Pro 2. 43 hours total with the case and a 10-minute charge for 3 hours of playback. The Kaira X is wired, so it never needs charging at all — a different kind of win.
• Best for voice chat → Razer Kaira X. A bendable cardioid boom mic with monitoring and game/chat balance beats six built-in mics for positional clarity.
• Best for portability → CMF BY NOTHING Buds Pro 2. A 46g case that fits in a pocket versus a 1.2-pound over-ear headset.
• Best for long-session comfort → Razer Kaira X. Flowknit memory foam cushions with reduced clamping force are designed for marathons.
• Best for workouts and weather → CMF BY NOTHING Buds Pro 2. IP55 water resistance and in-ear fit suit running and gym use; the Kaira X has no such rating.
• Best for hi-res wireless audio → CMF BY NOTHING Buds Pro 2. LDAC lossless transmission and Dirac-tuned dual drivers are the more modern audio chain.
In my opinion, these two aren't really competitors — they're answers to different questions. If your priority is gaming with a real mic, over-ear comfort and a wired connection that never dies, I'd buy the Razer Kaira X. If your priority is portable, noise-cancelling listening with long battery life across commuting, work and workouts, I'd buy the CMF BY NOTHING Buds Pro 2. Only buy the Kaira X if you game seriously on Xbox or PC; otherwise the Buds Pro 2 cover far more of daily life. Check the current price on Amazon before deciding, since both are budget options and value shifts over time.
what budget headphones
"Budget headphones" covers two very different shapes here: the Razer Kaira X is a wired over-ear gaming headset with 50mm drivers and a boom mic, while the CMF BY NOTHING Buds Pro 2 are wireless in-ear buds with ANC, LDAC and a charging case. Pick by form factor first — over-ear for desk gaming, in-ear for everything on the move.
how to get cheap headphones
The practical route is to decide what you can't live without, then match the spec sheet. Need a mic and Xbox support? The Kaira X's 3.5mm wired design keeps things simple. Need ANC and battery? The Buds Pro 2's 50dB hybrid ANC and 43-hour case cover it. Then check the current price on Amazon, since budget models fluctuate.
how long do cheap headphones last
The data sheets give warranty terms rather than lifespans: Razer lists a 2-year manufacturer warranty on the Kaira X, and CMF BY NOTHING lists a 1-year limited warranty on the Buds Pro 2. Real-world life depends on care — the Buds Pro 2's IP55 rating helps with sweat and moisture, while the Kaira X's wired connection removes battery degradation from the equation entirely.
how to make cheap headphones sound better
Start with the source and settings. The Kaira X benefits from pairing with Windows Sonic for virtual surround, which Razer specifically recommends to make the most of its drivers. On the Buds Pro 2, enable LDAC for lossless transmission, use the Dirac-tuned dual drivers with Dynamic Bass Boost 2.0, and make sure the adaptive ANC has a proper ear seal — the buds auto-detect leakage to optimize cancellation.
