How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to fix the seal on earbuds you already own and shut out the world with memory foam, choose COMPLY 100; if you need a tiny flat earbud you can actually lie on your side with, choose Xmenha Flat Sleep Mini. These two products share one goal — noise isolating sleep — but they get there in completely different ways. One is a replacement tip; the other is a whole earbud. That single difference decides everything.
• COMPLY 100 biggest strength: body-heat activated memory foam that expands into your ear canal for a genuinely superior in-ear seal, and it works with earbuds you already trust.
• COMPLY 100 biggest trade-off: it is not a complete earbud — no driver, no battery, no Bluetooth — and it only fits specific Etymotic, Westone, Klipsch, ISOtunes Pro and Jays models.
• Xmenha Flat Sleep Mini biggest strength: a flat, low-profile shell built specifically for side sleepers, plus a second pair in the box so you can rotate or share.
• Xmenha Flat Sleep Mini biggest trade-off: it is a wireless Bluetooth earbud with plastic housing, so its noise control comes from fit rather than from a foam seal, and Bluetooth 4 is an older wireless standard.
• Pick COMPLY 100 if you already love your IEMs and just want them quieter, more comfortable and more secure.
• Pick Xmenha Flat Sleep Mini if you have nothing to put in your ears yet and you sleep on your side.
Think of the COMPLY 100 as a fix rather than a purchase. It is a three-pair pack of Comply True Memory Foam replacement tips in black, size Large, and the entire pitch is that body heat softens the foam so it molds to the exact shape of your ear canal. That personalized fit is what does the work. A foam tip that expands to fill the canal creates a far tighter seal than a silicone tip sitting loosely in place, and a tighter seal is what actually reduces background noise. In my opinion, that is the whole reason people buy these: not for a new sound, but for a quieter room.
The practical benefits follow from that seal. Because outside noise drops, you do not need to push volume as high to hear detail, and the description notes improved bass and clarity as a result. The foam also grips, which is why these suit commuters, gym-goers and anyone whose earbuds slowly work their way loose. And there is a real comfort angle — Comply markets these as a way to eliminate the pain and pressure that hard tips create during long listening sessions. If your current IEMs sound fine but hurt after an hour, that is your signal.
Xmenha Flat Sleep Mini: Who It's For
The Xmenha Flat Sleep Mini attacks the problem from the opposite direction. Instead of making an existing earbud seal better, it makes the earbud itself small and flat enough to disappear into your ear. The headline feature is side-sleeper comfort: the ergonomic flat shell is designed to contour to your ear and remove the pressure points that a normal earbud creates when your head is on a pillow. If you have ever woken up because a hard plastic bud was digging into your ear, that is precisely the problem this design targets.
It is also a two-pack. That is the detail that separates it from most sleep earbuds. You get two pairs, and the brand frames the second pair as either a battery extender — switch when one runs low — or a shared pair you can lend to a partner for music, podcasts or calls. Either way, you are not stuck waiting on a charge to fall asleep. The claimed battery life is 30 hours, which is generous for something this small, and the balanced armature driver covers a 20Hz–20,000Hz range, so it is not a stripped-down beeper.
The rest of the spec sheet is a set of trade-offs worth knowing before you commit. Connectivity is Bluetooth 4 with a 10-meter range and no headphone jack, so it is fully wireless and fully dependent on a charge. Controls are touch-based with volume control on the bud itself. The housing is plastic in beige, and the brand positions the mini profile as discreet enough for office use and small ear canals — the same bud that vanishes under a pillow also vanishes in a meeting. The age range is listed at 10 and up. And note the language in the specs: the sleep mode is described as noise isolation, not active noise cancellation. The quiet comes from the fit and the seal, not from a cancellation circuit.
Who should skip it? Anyone who wants to keep using the wired IEMs they already own, or who wants an active noise cancelling circuit rather than a passive seal. And anyone wary of Bluetooth 4 as an older wireless generation should weigh that against the flat, sleep-first form factor.
• Best for side sleepers → Xmenha Flat Sleep Mini. The flat shell is built for lying on your ear; the COMPLY 100 does nothing about pillow pressure.
• Best for your existing IEMs → COMPLY 100. Memory foam tips upgrade the earbuds you already own instead of replacing them.
• Best for passive noise blocking → COMPLY 100. Heat-activated foam expanding in the canal creates the stronger seal of the two.
• Best for battery life → Xmenha Flat Sleep Mini. It claims 30 hours, and there is no battery at all in a foam tip.
• Best for two people, or one person who forgets to charge → Xmenha Flat Sleep Mini. Two pairs in the box means one can always be ready.
• Best for workouts and commuting → COMPLY 100. The secure foam grip is aimed at keeping earbuds from slipping during movement.
• Best for discretion at work → Xmenha Flat Sleep Mini. The mini, low-profile design is meant to be nearly invisible.
• Best for small ear canals → Xmenha Flat Sleep Mini. Its small-bud design is explicitly targeted at smaller canals; COMPLY 100 in Large is a fit upgrade for a specific set of IEMs.
If I were buying for myself, I would take the Xmenha Flat Sleep Mini, and I would take it specifically because of the flat, side-sleeper shape and the second pair in the box. The whole point of noise isolating sleep is that you actually stay asleep, and a bud that presses into your ear defeats that no matter how good the seal is. The COMPLY 100 is the smarter buy only if you already own a compatible Etymotic, Westone, Klipsch, ISOtunes Pro or Jays model and love how it sounds — in that case, foam tips are the cheapest way to make a good earbud quieter and more comfortable. Buy for the ear you have, not for the spec sheet.
are there earbuds for sleeping
Yes. The Xmenha Flat Sleep Mini is designed exactly for that — a flat, mini, in-ear shell meant to sit flush so side sleepers can rest on their ear. The COMPLY 100 is not an earbud at all; it is a replacement foam tip for compatible IEMs, so it only helps if you already own a matching pair.
what are the best noise cancelling earbuds for sleeping
That depends on what you mean by noise cancelling. The Xmenha Flat Sleep Mini uses noise isolation through its in-ear fit, not an active cancellation circuit, and adds side-sleeper comfort plus a 30-hour battery claim. The COMPLY 100 takes the other route — heat-activated memory foam that expands for a superior in-ear seal on earbuds you already own. For flat, sleep-first comfort I would lean Xmenha; for the tightest passive seal I would lean COMPLY.
can you sleep with noise cancelling earbuds
You can, but the shape matters more than the label. A standard hard-shell earbud presses into your ear against a pillow, which is the exact problem the Xmenha Flat Sleep Mini's flat profile is built to solve, and it is why that model is aimed at side sleepers. If you plan to sleep in earbuds, prioritize a low-profile design over raw features.
is it bad to sleep with noise cancelling earbuds
There is nothing in these spec sheets suggesting harm, but comfort and fit are the real considerations — anything that creates pressure points will disturb your rest, which is why flat, low-profile designs exist. The COMPLY 100 takes a different approach entirely: its foam is designed for all-day comfort and a secure grip, with care limited to warm water and a soft cloth, and no alcohol-based cleaners or lotions. Follow the care guidance and choose a shape that suits how you sleep.
