If you want to block outside noise and squeeze better bass out of earbuds you already own, choose BLLQ Memory Foam Ear; if you need a complete low-profile wireless earbud built for sleeping on your side, choose bluedery Flat Mini Earbuds.
• BLLQ Memory Foam Ear's biggest strength: slow-rebound memory foam tips that seal the ear canal for passive noise isolation and stronger bass — and they stay on the buds inside the charging case.
• BLLQ Memory Foam Ear's biggest trade-off: they are tips, not earbuds. No electronics, no battery, no Bluetooth — they only work if you already own compatible Soundcore earbuds.
• bluedery Flat Mini Earbuds' biggest strength: a 3g-per-bud, 2/5-inch-thin flat design with active noise cancellation, Bluetooth 5.4, touch controls and a 24-hour charging case — a full wireless system for side sleepers and small ears.
• bluedery Flat Mini Earbuds' biggest trade-off: 4 hours of play time per charge is modest for all-day listening, and the flat fit prioritizes comfort and discretion over an aggressive in-ear seal.
• Who BLLQ is for: Soundcore owners chasing cheap, effective noise isolation and deeper bass.
• Who bluedery is for: sleepers, side-sleepers and small-ear-canal users who want a discreet, self-contained earbud.
The BLLQ Memory Foam Ear is a set of replacement ear tips, not a pair of earbuds. That distinction matters more than anything else in this comparison. You get six foam tips in three sizes — one pair each of small, medium and large — made from slow-rebound memory foam that you compress, insert, and let expand to fill your ear canal. That expansion is the whole point: a foam tip that swells to the shape of your canal creates a physical seal, and a physical seal is what actually blocks the drone of a fan, a snoring partner or traffic outside the window.
In my opinion, that seal is the reason to buy these. Foam isolates passively, without any electronics, and the product notes that the tips also enhance bass — which makes sense, since a tighter seal means less low-end escaping before it reaches your ear. They're compatible with a specific range of Soundcore models, including the Life P3 and P2, Liberty 2 Pro, 2, 3 Pro and 3, plus other Soundcore true-wireless buds. If you own one of those and the stock silicone tips keep slipping or leave your ears sore after an hour, this is a straightforward upgrade.
One detail I genuinely like: BLLQ designed the foam to fit inside the charging case, so you don't have to pull the tips off every time you charge. Anyone who has wrestled silicone tips on and off a case knows how annoying that gets. The tips are black, made of memory foam, and the set measures roughly 4 x 3 x 0.4 inches packed.
Who should skip it? Anyone who doesn't own compatible Soundcore earbuds — the tips are useless on their own. And anyone who wants a complete, cable-free listening solution should look at the bluedery instead, because BLLQ brings no battery, no Bluetooth and no microphone to the table.
The bluedery Flat Mini Earbuds are a different animal entirely: a complete wireless earbud system built around one unusual idea — lying flat against your ear. Each bud weighs 3 grams, and the housing is just 2/5 inch thin, with a bio-mimetic curved shape meant to sit inside the natural contours of the canal without protruding. For side sleepers, that flat profile is the entire pitch. Roll onto your ear at 2 a.m. and there's no bulging shell digging into the pillow.
The spec sheet backs up the sleep angle. Bluetooth 5.4 handles the connection with one-step auto-pairing and a 10-meter range. Each bud runs up to 4 hours per charge, and the case adds over 20 hours more — the listing totals it as 24 hours of battery, with a 380 mAh case battery and Type-C fast charging. The audio side is a 6mm hybrid driver covering 20 Hz to 20,000 Hz at 5 ohm impedance, plus active noise cancellation and touch controls for music, volume and calls. A built-in mic with call noise reduction handles voice.
The honest trade-offs: 4 hours per bud means you'll be reaching for the case mid-afternoon if you wear them all day, and a warranty of one month is short. The deep, flush fit is designed for comfort and discretion rather than maximum passive isolation — that's where active noise cancellation picks up the slack, and it's a different feel from a foam seal.
I'd recommend these for people with small ear canals who find standard buds painful, for anyone who wants hidden earbuds at work, and above all for side sleepers who need something weightless. If you already own Soundcore buds and just want a better seal, skip these — you don't need a second pair of earbuds to solve a tips problem.
• Best for noise isolation through a physical seal → BLLQ Memory Foam Ear. Memory foam expands to fill the canal; that's passive isolation no firmware can fully replicate.
• Best for active noise cancellation → bluedery Flat Mini Earbuds. They list ANC as a control feature; the BLLQ tips have no electronics at all.
• Best for side sleepers → bluedery Flat Mini Earbuds. 3g per bud and a 2/5-inch flat profile versus replacement tips on full-size Soundcore buds.
• Best for small ear canals → bluedery Flat Mini Earbuds. They're explicitly engineered for small canals; BLLQ's smallest tip is one of three standard sizes.
• Best for battery life → bluedery Flat Mini Earbuds. 4 hours per bud plus a 24-hour case, versus no battery in the BLLQ set.
• Best for bass on Soundcore buds → BLLQ Memory Foam Ear. The tighter seal is credited with enhancing low-end response.
• Best for charging convenience → BLLQ Memory Foam Ear. The foam stays on the buds inside the case — no removal needed.
• Best for people who don't own Soundcore earbuds → bluedery Flat Mini Earbuds. The BLLQ tips only fit compatible Soundcore models.
If I had to pick one, I'd buy the bluedery Flat Mini Earbuds. Not because foam tips are bad — they're excellent at what they do — but because bluedery solves the whole problem in one purchase: a complete wireless earbud, a charging case, ANC, a mic and a flat 3g design that lets you sleep on your side. The BLLQ set only makes sense as an add-on for someone who already owns compatible Soundcore earbuds and wants a firmer seal. If that's you, buy the BLLQ. If you're starting from nothing, buy bluedery.
FAQ
are there earbuds for sleeping
what are the best noise cancelling earbuds for sleeping
That depends on the kind of noise control you want. The bluedery buds offer active noise cancellation with a low-profile fit built for side sleepers. The BLLQ foam tips take the other route: a memory foam seal that blocks distractions passively and enhances bass, provided you own compatible Soundcore earbuds.
can you sleep with noise cancelling earbuds
You can, and flat, lightweight designs are made for it. At 3g per bud with a flush profile, the bluedery earbuds are shaped to avoid pressure points when you lie on your side. Bulkier in-ear designs are the ones that tend to cause discomfort overnight.
is it bad to sleep with noise cancelling earbuds
The main concerns are pressure and hygiene, not the noise cancellation itself. A lightweight, flush-fitting bud like the bluedery reduces pressure points, and the BLLQ foam tips are described as reducing ear pain for all-day comfort. Keep your tips and buds clean, and don't crank volume for hours.
