How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of over-ear headphones that can carry you through a full workweek of calls, commutes and long focus sessions, choose Anjetsun Headphones; if you need something you can actually lie on at night that shuts out the air conditioner and won't wake you when you roll over, choose Niderson Mini ANC Sleep.
These two products share a keyword — "ANC" — and almost nothing else. One is a full-size over-ear headphone built around battery life and all-day wear. The other is a tiny in-ear bud built around a very specific problem: sleeping on your side without a hard plastic shell digging into your ear. Comparing them head-to-head only makes sense if you start from the job you're hiring them to do.
• Anjetsun Headphones — biggest strength: Up to 80 hours of playtime with ANC off (50–60 hours with it on), plus a Bluetooth 5.4 connection that reaches phones, laptops, tablets, TVs and PCs, and magnetic ear pads you can pop off and replace.
• Anjetsun Headphones — biggest trade-off: It's a 0.73 kg over-ear package with oval ABS earcups. That's a lot of headphone, and it is not something you can lie on or wear in bed.
• Niderson Mini ANC Sleep — biggest strength: A 3.0 g-per-bud, silicone-tipped in-ear design with a Sleep Mode that locks the touch controls and mutes low-battery alerts, so pillow taps and beeps don't wake you.
• Niderson Mini ANC Sleep — biggest trade-off: Its ANC is explicitly tuned for low-frequency noise like AC hum, distant traffic and steady snoring, and the brand notes it may not eliminate sharp, high-frequency sounds. It's a sleep tool, not an all-purpose headphone.
• Pick Anjetsun if you want one wireless headphone for work, study, travel and calls.
• Pick Niderson if the thing you actually need is silence at 2 a.m. without a hard shell pressed against your ear.
The Anjetsun pair is a classic over-ear wireless headphone, and the spec sheet reads like it was written for someone who is tired of charging things. The headline number is 80 hours of battery life with ANC turned off, dropping to roughly 50–60 hours with noise cancelling active. Either way, that's measured in days, not hours — you can plausibly get through a workweek of commutes and meetings without thinking about the charging cable.
The build is practical rather than precious. Oval earcups wrapped in soft PU leather, an adjustable headband, and 40 mm dynamic drivers covering a 20Hz–20,000Hz range at 32 ohm impedance. The detail I like most is the detachable magnetic ear pads: earpads are the first thing to wear out or get grimy on any over-ear headphone, and being able to pull them off and replace them is a genuinely thoughtful bit of long-term design. You also get a cable, a protective bag and a user manual in the box.
Connection-wise it uses Bluetooth 5.4 with a 10-metre range, and there's a built-in microphone for meetings, online classes and calls. Controls are touch-based on the earcup — play, pause, volume, call management. There's no headphone jack, so this is wireless only.
Who should buy it: anyone who wants one headphone for the office, the café, the commute and the flight. The ANC is aimed at reducing ambient chatter and everyday background noise, which is exactly the "I need to concentrate" use case. The 0.73 kg weight and over-ear fit mean it's a wear-it-on-your-head product, not a wear-it-in-bed product.
Who should skip it: side sleepers, and anyone who wants earbuds they can forget about in a pocket. If your main listening happens lying down at night, this isn't the tool — the earcups are far too bulky for that, and there's no sleep-specific mode to stop accidental touches.
The Niderson D20 is a much more specialised product, and it's honest about it. The whole design brief is "side sleepers." Each bud weighs 3.0 g and uses ultra-soft, skin-friendly silicone tips shaped to follow the curve of your inner ear, so it doesn't press into the ear canal when your head is on a pillow.
The feature that makes or breaks a sleep bud is the one nobody thinks about until they've been woken up by it: accidental touch. The D20 has a dedicated Sleep Mode that locks the touch controls so a stray pillow tap doesn't pause your audio, and it mutes the low-battery voice alerts so a cheerful robot voice doesn't yank you out of sleep at 3 a.m. That's the kind of detail that tells you the product was designed for a real problem.
Noise cancelling here is low-frequency focused. The brand states plainly that ANC is designed for low-frequency noise — AC hums, distant traffic, consistent snoring — and may not fully eliminate sharp, high-frequency sounds. That's a refreshingly specific claim, and it matches what ANC actually does well. Think of it as a "sound cocoon" for sleep, meditation or winding down.
On the audio side you get 14.2 mm dynamic drivers described as bass-forward, four microphones with Environmental Noise Cancellation for calls, Bluetooth 5.4 with a 15-metre range, and IPX7 water resistance. Battery life is listed at 56 hours, with the compact USB-C case (roughly 2 x 2 x 0.88 inches, 30 g) providing extra charges across the night. A 2-year warranty is listed, and the colour is khaki.
Who should buy it: light sleepers, people who share a bed with a snorer, side sleepers who've given up on normal earbuds, and anyone who wants white noise or a podcast running all night without a hard plastic lump in their ear.
Who should skip it: anyone who wants one headphone to do everything. These are tiny in-ear buds. If you want to wear over-ear headphones at a desk for eight hours of meetings, the D20 is the wrong shape for that job.
• Best for battery life → Anjetsun Headphones. 80 hours with ANC off and 50–60 hours with it on beats the D20's 56-hour figure, and it does it in a single pair with no case involved.
• Best for sleeping on your side → Niderson Mini ANC Sleep. 3.0 g buds with silicone tips and a Sleep Mode that locks touch controls — this is the entire point of the product.
• Best for all-day work and calls → Anjetsun Headphones. Over-ear fit, 40 mm drivers, built-in mic, Bluetooth 5.4 across laptops, phones, tablets, TVs and PCs.
• Best for blocking steady, low-frequency noise at night → Niderson Mini ANC Sleep. ANC aimed squarely at AC hum, distant traffic and consistent snoring.
• Best for replaceable parts and long-term hygiene → Anjetsun Headphones. Detachable magnetic ear pads you can swap out.
• Best for wearing in bed or on a pillow → Niderson Mini ANC Sleep. The Anjetsun's earcups make lying down impractical.
• Best for workouts or sweaty environments → Niderson Mini ANC Sleep. IPX7 water resistance is listed for the D20; the Anjetsun sheet lists no water-resistance rating.
• Best for a single do-everything headphone → Anjetsun Headphones. The D20 is a specialist; the Anjetsun is a generalist.
If I had to buy one, I'd buy the Anjetsun Headphones. In my opinion it's the more versatile purchase: 80 hours of battery, a proper over-ear fit for long work sessions, Bluetooth 5.4 with a mic for calls, and magnetic ear pads that make it last longer. It covers commuting, studying, travel and desk work in one product.
That said, I'd recommend the Niderson Mini ANC Sleep without hesitation if your actual problem is sleep. No over-ear headphone solves "I can't lie on my side with these on," and the Sleep Mode plus 3.0 g silicone-tipped design is built specifically for that. These aren't competitors so much as two different answers — buy the one that matches the job you have.
Niderson Mini ANC Sleep, clearly. Its buds weigh 3.0 g each with soft silicone tips designed to sit without pressure even when you're lying on your side, and Sleep Mode locks the touch controls so your pillow doesn't pause your audio. The Anjetsun's over-ear earcups aren't designed to be slept on at all.
Anjetsun lists up to 80 hours with ANC off and 50–60 hours with ANC on. Niderson lists 56 hours of average battery life, with the USB-C case providing multiple extra charges. Niderson also notes actual playtime varies with volume and ANC use.
Yes, both list Active Noise Cancellation. The important difference is intent: Anjetsun's ANC targets ambient office, café and commuting noise for focus, while Niderson's is tuned for low-frequency sounds like AC hum, distant traffic and steady snoring, and the brand notes it may not fully block sharp, high-frequency noises.
If you want a single wireless headphone for work, calls, travel and everyday listening, the Anjetsun over-ear is the more flexible choice. If your priority is sleep or relaxation at night, the Niderson D20 is the one built for it. Check the current price on Amazon for whichever one matches your main use case.
