How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless gaming headset with spatial surround sound and a detachable boom mic, choose Amazon Renewed Razer BlackShark V2; if you need tiny, side-sleeper-friendly earbuds with active noise cancellation and a smart sleep mode, choose Niderson Mini ANC Sleep.
• Amazon Renewed Razer BlackShark V2 — biggest strength: THX 7.1 spatial surround and 50mm Triforce Titanium drivers tuned for gaming, with a detachable cardioid mic for voice chat.
• Amazon Renewed Razer BlackShark V2 — biggest trade-off: It's a renewed (pre-owned, Amazon-qualified refurbished) unit, it's heavy at 320 g, and its battery life is a fraction of the Niderson's.
• Niderson Mini ANC Sleep — biggest strength: A 3.0 g-per-bud in-ear design built specifically for side sleepers, with active noise cancellation, a touch-locking Sleep Mode, and long battery life.
• Niderson Mini ANC Sleep — biggest trade-off: ANC targets low-frequency noise only, and there's no boom mic or spatial gaming audio — it's a sleep and relaxation tool, not a gaming rig.
• Pick the Razer if your priority is immersive game audio and clear in-game comms on PC, Mac, PS4, PS5 or Switch.
• Pick the Niderson if your priority is drifting off on your side without pressure points, pillow taps or low-battery voice alerts.
This is a gaming headset first. The spec sheet leans hard into that: THX 7.1 spatial surround for directional audio cues, 50mm Triforce Titanium drivers split into three parts so highs, mids and lows can be tuned separately, and a frequency range stretching from 12 Hz to 28 kHz. In practice that means footsteps, reloads and distant gunfire arrive with a sense of direction rather than as a flat wall of sound — the whole point of spatial audio in a competitive game.
The comfort story is more interesting than most gaming headsets. Razer uses oval, cooling gel-infused cushions here, and the enclosure is memory foam. If you've ever pulled off a headset after a long session and felt that hot, pinched feeling around your ears, that's exactly what this design is aimed at. The mic is detachable — a Razer Hyperclear cardioid unit with a focused pickup area, and you can fine-tune voice settings through Razer Synapse 3. Detaching it matters if you also want to use the headset for music or video without a boom arm in your face.
Now the honest trade-offs. It's wireless over Bluetooth 5.2 — there's no 3.5mm jack on this model — and battery life is rated at 24 hours, which is fine for a week of evenings but nowhere near the Niderson's figure. It weighs 320 g, which is on the heavy side for anything you'd wear in bed. And it's an Amazon Renewed product: professionally inspected and tested to work and look like new by Amazon-qualified suppliers, backed by a 90-day limited warranty and the Amazon Renewed Guarantee. That's a real, defined safety net — but it is a refurbished unit, so if you insist on a sealed retail box, skip it. I'd steer gamers and streamers toward it; I'd steer side sleepers away.
The Niderson Mini ANC Sleep is built around one very specific problem: falling asleep on your side while wearing earbuds. Each bud weighs 3.0 g, and the ultra-soft skin-friendly silicone tips follow the natural curve of your inner ear. That's the opposite of a bulky over-ear cup digging into a pillow. If you're a side sleeper, this is the entire reason the product exists.
The feature I actually think is cleverest is Sleep Mode. Activating it locks the touch controls so a shifting pillow doesn't skip your track, and it mutes low-battery voice alerts so nothing jolts you awake at 3 a.m. Anyone who's been woken by a cheerful "battery low" announcement knows why that matters.
On the audio side you get active noise cancellation aimed at low-frequency sound — air-conditioner hum, distant traffic, steady snoring. The brand is upfront that ANC won't erase sharp, high-frequency noise, and I'd take that note at face value rather than expecting total silence. Playback runs up to 56 hours on a charge, with extra charges in the compact USB-C case, though real-world time shifts with volume and ANC use. The 14.2mm dynamic drivers and four mics with ENC make late-night calls and white-noise playback sound fuller than the tiny shell suggests.
Where it falls short: no boom mic, no spatial gaming audio, and it's in-ear only in Khaki. Bluetooth 5.4 gives you a 15-meter range. If you want one pair for gaming, calls and travel, this isn't it. If you want to sleep with something in your ears, it's the more sensible pick of these two.
Side-by-Side: Which Should You Choose?
• Best for sleep and side sleeping → Niderson Mini ANC Sleep. 3.0 g buds and silicone tips that stay comfortable against a pillow.
• Best battery life → Niderson Mini ANC Sleep. Up to 56 hours versus 24 hours.
• Best voice chat for gaming → Amazon Renewed Razer BlackShark V2. The detachable Hyperclear cardioid mic plus Synapse 3 tuning.
• Best for muting interruptions at night → Niderson Mini ANC Sleep. Sleep Mode locks touch controls and silences low-battery alerts.
• Best for console and PC compatibility → Amazon Renewed Razer BlackShark V2. Listed for PC, Mac, PS4, PS5 and Switch.
• Best for quieting a noisy room → Niderson Mini ANC Sleep. ANC targets low-frequency hums like AC units and traffic.
• Best for prioritizing a sealed, brand-new unit → Niderson Mini ANC Sleep. The Razer is a renewed product with a 90-day limited warranty.
In my opinion, the answer depends entirely on the room you're sitting in. If you're at a desk chasing directional audio and clear comms, I'd buy the Amazon Renewed Razer BlackShark V2 — the spatial surround, TriForce drivers and detachable mic are a coherent package, and the Renewed Guarantee plus 90-day warranty covers the refurbished angle. If you're in bed, on your side, I'd buy the Niderson Mini ANC Sleep without hesitation: 3.0 g per bud, Sleep Mode and up to 56 hours are exactly what that job needs. Two different products for two different problems.
what is the best selling headphones
That framing depends on the category, not one single winner. Gaming headsets, sleep earbuds and everyday listening buds sell in separate lanes, which is why these two products barely compete — one is a wireless gaming headset, the other an ANC sleep earbud. Pick the lane that matches your daily use.
what is the best selling headphones of all time
No single model owns that title across every category. What actually drives volume is fit-for-purpose design: the BlackShark V2 targets PC and console gamers with THX 7.1 and a detachable mic; the Niderson D20 targets side sleepers with 3.0 g buds and Sleep Mode. Different buyers, different best sellers.
what are the best selling headphones in the world
Popularity splits by region and use case. Over-ear gaming headsets dominate desk setups, while tiny in-ear ANC buds dominate sleep, travel and relaxation. The BlackShark V2 sits on the gaming side with 50mm drivers and 24-hour battery; the Niderson Mini sits on the sleep side with 56 hours and 14.2mm drivers.
what is the most popular brand of headphones
There isn't one brand that wins every category — buyers follow the use case. Razer is well established in gaming peripherals, and the BlackShark V2 reflects that with THX 7.1 and Synapse 3 mic tuning. Niderson is a sleep-focused name, and the Mini ANC Sleep reflects that with skin-friendly silicone and a touch-locking Sleep Mode.
