• BLLQ Memory Foam Ear's biggest strength: three pairs of slow-rebound memory foam tips (S/M/L) that block distractions, boost bass and fit straight into the charging case.
• BLLQ Memory Foam Ear's biggest trade-off: it is not a complete earbud — you must already own compatible Soundcore TWS earphones, and the buds and case are not included.
• ERAZERL MS216's biggest strength: a 3.0g, 10.5mm slim in-ear design in soft silicone, tuned for side sleepers, with 60 hours of battery life and Bluetooth 6.0.
• ERAZERL MS216's biggest trade-off: it's a full headphone set, so you're buying an entire product rather than a small accessory, and it isn't meant to replace tips on another brand's buds.
• Who BLLQ fits: someone who already owns Soundcore Life P3/P2/Liberty-series buds and wants a better seal and more isolation for less fuss.
• Who ERAZERL fits: someone who wants a dedicated, feather-light sleep earbud they can wear all night, including on their side.
This is a set of replacement tips, not a pair of earbuds. You get six pieces — three pairs in small, medium and large — made from premium memory foam that slowly rebounds to fill your ear canal. That slow rebound is the whole point: the foam molds to the shape of your ear instead of pressing against it, and the result is a tighter seal that helps block outside noise and pushes more bass into what you're hearing.
The clever part is the fit into the charging case. A lot of foam tips are too bulky to sit back in the case, so you end up pulling them off every night and losing them. BLLQ specifically designs these to slide into the Soundcore charge case without removal, so you can leave them on, drop the buds in, and charge like normal.
Who should buy it? Anyone with compatible Soundcore TWS buds — Life P3, P2, Liberty 2 Pro, Liberty 2, Liberty 3 Pro, Liberty 3 and similar Soundcore models — who wants more isolation and a more comfortable all-day fit. The listing frames it around working from home, workouts, video calls and relaxing, which matches the "comfort plus isolation" pitch. If your ears hurt after an hour with stock silicone tips, foam is a genuinely different feel.
Who should skip it? Anyone who doesn't own those Soundcore earbuds. There is no earbud and no case in the box, so this does nothing on its own. And if you want a single product that just works out of the box for sleeping, this isn't that — it's a tuning part for hardware you already have.
The MS216 is a purpose-built sleep earbud. The headline spec is weight: each bud is just 3.0g with an ultra-thin 10.5mm profile, wrapped in super soft silicone. That combination is what makes side sleeping plausible — there's very little material to press into your ear when your head is on a pillow, and the contoured, polished shape is designed to sit snugly without pressure. There's also a dedicated sleep mode that suppresses low-level audio so you're not getting thumped by bass as you drift off.
Battery is the other big story. ERAZERL quotes 60 hours of standby and a full charge in just 1.5 hours over USB-C, so you can top up quickly and not think about it for a long stretch. Bluetooth 6.0 handles the connection with low latency and a stable signal, and a high-sensitivity mic with noise-reduction algorithms is there for calls. Sound comes from Φ6mm drivers with a 20Hz–20,000Hz range, and touch controls handle playback and noise control.
Who should buy it? Side sleepers, restless sleepers, and anyone who wants a complete, self-contained sleep earbud they can wear all night without sore ears. The design brief of "don't put pressure on the canal, don't feel sore after all-day wear" fits people who currently wake up with aching ears from normal buds.
Who should skip it? If you already love your Soundcore buds and just want a better seal, buying a whole second headphone set is a bigger step than swapping tips. And if you want maximum isolation from a passive foam seal rather than an active noise-cancellation system, the tip route may suit you better.
Side-by-Side: Which Should You Choose?
• Best for side sleeping → ERAZERL MS216. 3.0g per bud and a 10.5mm thin profile are built for pillow contact.
• Best for battery life → ERAZERL MS216. 60 hours of standby and a 1.5-hour charge beat a tip with no battery at all.
• Best for charging convenience → BLLQ Memory Foam Ear. The tips stay on the buds and fit straight into the Soundcore case.
• Best for calls → ERAZERL MS216. A built-in noise-reduction mic and Bluetooth 6.0 are made for voice.
• Best for a zero-commitment tweak → BLLQ Memory Foam Ear. Small accessory, big change in comfort and isolation.
• Best for a complete out-of-the-box product → ERAZERL MS216. Nothing else needed; it's a full headphone set.
• Best for someone with no earphones yet → ERAZERL MS216. BLLQ requires compatible Soundcore buds you supply yourself.
In my opinion, the ERAZERL MS216 is the pick for anyone whose actual goal is noise-isolating sleep. It's the whole package: light enough for side sleepers, soft silicone, a sleep mode, and a battery that covers night after night. The BLLQ tips are excellent at what they do — better seal, more bass, more isolation — but they only help if you already own compatible Soundcore buds. If you do, buy them; if you're starting from scratch, I'd go with the MS216.
are there earbuds for sleeping
Yes. The ERAZERL MS216 is built specifically for that — 3.0g per bud, a 10.5mm ultra-thin profile, soft silicone and a sleep mode that mutes low-level audio. The BLLQ foam tips aren't earbuds at all; they're replacement tips for compatible Soundcore TWS models.
what are the best noise cancelling earbuds for sleeping
Based on the specs, the MS216 is the stronger sleep option because it combines active noise cancellation, touch controls and a body designed around side sleepers. The BLLQ tips take a different route — passive isolation through a slow-rebound foam seal that blocks distractions.
can you sleep with noise cancelling earbuds
It depends on the fit. The MS216 is engineered for it: feather-light, contoured, and slim enough that side sleepers aren't pressing a hard shell into their ear. A bulky pair of normal buds is a different story — weight and protrusion are what make sleeping in them uncomfortable.
is it bad to sleep with noise cancelling earbuds
The main concern is pressure and ear soreness from prolonged wear, not the noise cancelling itself. That's why the MS216's 3.0g weight, soft silicone and no-pressure contour matter — they're designed to reduce that soreness for all-night wear.
