• Quidnuran's biggest strength: it's built around noise reduction first — a small, lightweight, "invisible" earbud designed to block outside sound so you can focus, sleep or travel without being noticed.
• Quidnuran's biggest trade-off: the sheet gives no battery life figure and no dedicated sleep-position claim, so you're buying it mainly for the noise-blocking and low-profile design, not for marathon runtime.
• goazzzl's biggest strength: a true sleep-first build — ultra-light 3.0g mini earbuds, a small-ear semi in-ear shape, Bluetooth 5.4, and a charging case rated for up to 35–40 hours of total use.
• goazzzl's biggest trade-off: its noise control field is listed as "None", so it blocks sound through fit and sealing rather than any active system, and the semi in-ear shape lets in more ambient noise than a deep plug.
• Who each is for: Quidnuran for office, library, snoring and travel use where quiet matters most; goazzzl for side sleepers and small-eared users who want the earbuds to disappear all night and last through the week.
The Quidnuran Sleep Headphones Noise (model T16) is a white, plastic-bodied wireless earbud that positions itself as a sleep earplug first. The design brief is clear from the feature set: small, lightweight, discreet, "not easily noticeable." That's an earbud meant to vanish into your ear so you can use it in an office, a library or a quiet carriage without anyone clocking that you're wearing it. If you've ever been self-conscious about a glowing or chunky earbud at your desk, that's the problem this one is solving.
The noise-blocking angle is the headline. Quidnuran describes excellent noise reduction that shields you from external interference and helps you focus — and pairs that with lossless, high-fidelity audio so music, podcasts and white noise still sound good through the seal. Bluetooth 5.3 gives you a stable connection with 10 metres of range, lower latency and better anti-interference, so you can walk away from your phone without the audio stuttering. IPX5 waterproofing means sweat, rain and damp gym environments aren't a problem.
Who should buy it: side sleepers and snorers who mainly want external noise shut out, workers who want an invisible earbud for focus, and travellers who want something discreet for a flight or a meditation session. Who should skip it: anyone who needs a stated battery number before committing, or who wants a dedicated small-ear-canal fit — this one is about blocking noise and staying hidden, not about being the smallest possible bud.
The goazzzl Sleep Earbuds are the more sleep-engineered of the two. The spec that jumps out is weight: 3.0g per earbud, described as ultra-light and pressure-free. The pitch is that even lying on your side, they won't press into your ear or wake you up — which is the exact failure mode that makes most earbuds useless for actual sleeping. They're also designed specifically for small ear canals with a semi in-ear shape, so you get a natural fit rather than that tight, plugged feeling.
The second smart detail is the no-light design. After pairing, the earbuds don't flash, so they stay truly invisible — good for a dark bedroom, an office, a classroom or a library. Bluetooth 5.4 handles the connection with fast pairing and stable, drop-free playback, and touch controls let you run music, calls and volume without reaching for your phone. The LED display on the case shows battery the moment you open it, and the numbers are solid: about 4–5 hours per charge, up to 35–40 hours with the case. A 3-year manufacturer warranty is listed too, which is unusually long for this category.
Who should buy it: side sleepers, people with small ears who find normal buds painful or loose, and anyone who wants a visible battery readout so they're never guessing. Who should skip it: if you specifically want active noise cancellation, look elsewhere — the noise control field on this one is "None". Its quiet comes from the fit, so it will soften a snoring partner or traffic hum but won't erase a loud room.
• Best for blocking outside noise → Quidnuran Sleep Headphones Noise. Noise reduction is the core of its design brief, and it's the feature the product is named for.
• Best for side sleeping → goazzzl Sleep Earbuds. The 3.0g weight and pressure-free side-sleep claim are exactly what a restless sleeper needs.
• Best for small ear canals → goazzzl Sleep Earbuds. It's explicitly built for small ears with a semi in-ear fit; Quidnuran's sheet makes no ear-size claim.
• Best for battery confidence → goazzzl Sleep Earbuds. 4–5 hours per charge and up to 35–40 hours with the case, plus an LED display. Quidnuran lists no battery figure.
• Best for staying unnoticed at work → Quidnuran Sleep Headphones Noise. Discreet, lightweight and explicitly pitched at office and library use.
• Best for workouts and damp environments → Quidnuran Sleep Headphones Noise. IPX5 waterproofing covers sweat and rain; goazzzl lists waterproofing in its title but no IP rating.
• Best for newer wireless tech → goazzzl Sleep Earbuds. Bluetooth 5.4 versus Quidnuran's Bluetooth 5.3, though both are current-generation and both are stable.
• Best for warranty peace of mind → goazzzl Sleep Earbuds. A 3-year manufacturer warranty is listed; Quidnuran's sheet gives no warranty information.
My Verdict
how to block out noise with headphones
Passive blocking comes from the seal the earbud creates in your ear, not from the electronics. Both of these rely on that: the Quidnuran Sleep Headphones Noise is designed around noise reduction, while the goazzzl Sleep Earbuds use a semi in-ear fit that seals gently. For a loud room, a deeper, snugger fit blocks more.
are there noise cancelling headphones for sleeping
Yes, but not every sleep earbud has active cancellation. The goazzzl Sleep Earbuds list their noise control as "None", so they block sound purely through fit and sealing. The Quidnuran Sleep Headphones Noise is described as providing excellent noise reduction to shield external interference, which is the noise-blocking angle it's built around.
is it safe to wear noise cancelling headphones while sleeping
The practical concern is comfort and pressure over several hours, not the earbud itself. That's why fit matters: the goazzzl Sleep Earbuds are 3.0g with a pressure-free side-sleep design, and the Quidnuran Sleep Headphones Noise uses soft materials and an ergonomic shape for long wear. Pick the fit that suits how you sleep.
what are the best noise cancelling sleep headphones
In my opinion, it depends on whether you want blocking or all-night comfort. For blocking, I'd choose the Quidnuran Sleep Headphones Noise — noise reduction is its whole design. For sleeping through the night, I'd choose the goazzzl Sleep Earbuds for their 3.0g weight, small-ear fit and up to 35–40 hours of case battery.
