If you want dependable all-day over-ear listening for streaming, choose Sony WH-CH720NB; if you need earbuds built for side sleepers and overnight audio, choose Niderson Mini ANC Sleep. That single split — over-ear versus in-ear, wake-hours versus bedtime — decides almost everything about which of these best selling headphones actually fits your life. Both are wireless, both cancel noise, and both target streaming, but they solve completely different problems. Here's how I'd sort them out.
• Sony WH-CH720NB biggest strength: Full over-ear design with Dual Noise Sensor tech, an Integrated Processor V1, DSEE sound enhancement, and up to 35 hours of rated battery life with quick charge.
• Sony WH-CH720NB biggest trade-off: It's a 192g over-ear headphone with no wired jack, so it's bulky for sleep and can't be used passively with a cable.
• Niderson Mini ANC Sleep biggest strength: Purpose-built for side sleepers — just 3.0g per bud, skin-friendly silicone tips, a Sleep Mode that locks touch controls and mutes low-battery alerts, and a rated 56 hours of battery.
• Niderson Mini ANC Sleep biggest trade-off: Its ANC targets low-frequency noise only (AC hums, distant traffic, steady snoring) and won't erase sharp, high-pitched sounds.
• Pick Sony WH-CH720NB for: Streaming music, shows, and calls during the day on a phone, tablet, or laptop.
• Pick Niderson Mini ANC Sleep for: Falling asleep to white noise, meditation tracks, or quiet audio without pressure on your ears.
The WH-CH720NB is Sony's take on an everyday over-ear headphone, and the spec sheet tells you where it's aimed. The Dual Noise Sensor technology paired with an Integrated Processor V1 is the same processing family Sony uses across its noise-canceling lineup, and DSEE is there to lift compressed digital files closer to how they were recorded. In practice, that's a headphone for someone who streams a lot — playlists, podcasts, series — and wants vocals to stay natural and the tuning to feel balanced rather than bass-heavy.
Who should skip it? Anyone shopping for sleep. This is an over-ear headphone with no headphone jack, so it isn't something you'd wear lying on your side, and it can't fall back to a wired connection when the battery runs down. If your main use is drifting off to audio in bed, it's the wrong shape entirely. If your main use is streaming through the day, it's a strong, comfortable fit.
Niderson Mini ANC Sleep: Who It's For
The Niderson Mini ANC Sleep is a different species of product. These are in-ear buds designed around one job: letting side sleepers listen comfortably overnight. Each bud weighs just 3.0g, and the silicone tips are made to reduce pressure in the ear canal — the specific reason people who sleep on their side usually can't wear normal earbuds. The Khaki color and compact USB-C case (roughly 2 x 2 x 0.88 inches, 30g) keep the whole kit small enough for a nightstand or a carry-on.
The Sleep Mode is the feature that matters most here. Turn it on and the touch controls lock, so rolling onto your pillow doesn't skip tracks or change volume, and low-battery voice alerts are muted so nothing jolts you awake. That's a small-sounding detail that makes or breaks overnight use. ANC on the D20 is tuned for low-frequency noise — air conditioning hum, distant traffic, consistent snoring — which is exactly the steady background noise that keeps light sleepers up. Niderson is upfront that it won't fully kill sharp, high-frequency sounds, and I'd take that as honest rather than a weakness.
Audio comes from 14.2mm dynamic drivers with a bass-forward tuning, which suits white noise, meditation tracks, and ambient audio well. Four mics with ENC handle voice pickup for late-night calls in shared spaces. Battery is rated at 56 hours, and Niderson notes actual playtime varies with volume and ANC use, and recommends a full charge of both buds and case before bed. Bluetooth 5.4 with a 15-meter range rounds it out.
Side-by-Side: Which Should You Choose?
• Best for streaming during the day → Sony WH-CH720NB. Over-ear drivers, DSEE, and balanced tuning suit music, shows, and calls.
• Best for sleep and side sleepers → Niderson Mini ANC Sleep. 3.0g buds, silicone tips, and a Sleep Mode made for overnight use.
• Best for battery life → Niderson Mini ANC Sleep on paper at a rated 56 hours versus Sony's up to 35 hours, though Sony adds quick charge.
• Best for long wear comfort while awake → Sony WH-CH720NB. A 192g over-ear with ergonomic pads is built for hours of daytime wear.
• Best for blocking steady low-frequency noise at night → Niderson Mini ANC Sleep, whose ANC is tuned specifically for hums, traffic, and snoring.
• Best for pairing two devices at once → Sony WH-CH720NB with Multipoint Connection.
• Best for sensitive ears → Niderson Mini ANC Sleep, thanks to skin-friendly silicone tips that reduce ear canal pressure.
• Best for white noise and meditation tracks → Niderson Mini ANC Sleep; its 14.2mm bass drivers and sleep-focused design fit ambient audio.
• Best true wireless earbuds for streaming in bed → Niderson Mini ANC Sleep, since it's the only in-ear option of the two.
• Best for sports earbuds for streaming → Neither is marketed as sport-specific, so judge by fit: the Niderson's secure in-ear design is closer to that use case than an over-ear.
If I had to buy one, I'd pick based on the clock, not the spec sheet. For streaming through a normal day — work, commutes, music, calls — I'd buy the Sony WH-CH720NB: the over-ear comfort, DSEE sound, Multipoint, and up-to-35-hour battery are exactly what daytime listening needs. For streaming at night, I'd buy the Niderson Mini ANC Sleep, because the 3.0g fit, Sleep Mode, and low-frequency ANC solve a problem the Sony simply isn't shaped for. In my opinion, that's the cleanest way to split these two best selling headphones: Sony for the day, Niderson for the night.
FAQ
Sales leaders shift constantly and this page doesn't track sales figures. What I can say from the data sheets is that Sony's WH-CH720NB sits in the mainstream over-ear ANC category, while the Niderson Mini ANC Sleep targets a narrower side-sleeper market — different audiences, different demand.
Sony is one of the most recognized names in headphones, and the WH-CH720NB carries its Integrated Processor V1 and DSEE technology. Niderson is a smaller, sleep-focused brand. Popularity aside, the real question is whether you want over-ear or in-ear.
