If you want to upgrade the earbuds you already own into a serious noise-isolating sleep tool, choose COMPLY 100; if you need a standalone, ultra-soft plug built for side sleepers and rated to block up to 45dB, choose Scozkc Sleep Earplugs.
• COMPLY 100 — biggest strength: body-heat activated memory foam that molds to your ear canal for a personalized, secure seal that boosts noise isolation and bass. Biggest trade-off: it's not a standalone earplug — it's a replacement tip that only fits select Etymotic, Westone, Klipsch, ISOtunes Pro and Jays models.
• Scozkc Sleep Earplugs — biggest strength: a 45dB SNR rating plus four sizes (XS/S/M/L) and a low-profile shape designed to sit flush for side sleepers. Biggest trade-off: it's a passive plug, not an audio accessory, so there's no listening benefit.
• Who COMPLY 100 is for: people who already own compatible IEMs and want better isolation and comfort from the gear they have.
• Who Scozkc Sleep Earplugs is for: anyone who wants simple, reusable quiet for sleeping, snoring, travel or noise sensitivity — no existing earbuds required.
The COMPLY 100 is a Core Series memory foam replacement tip, sold as three pairs of large tips in black. The core idea is simple: swap the stock silicone tip on a compatible in-ear monitor for Comply's True Memory Foam, and let your own body heat soften and expand it so it molds to the shape of your ear canal. That personalized fit is the whole point — it eliminates the pressure and pain that hard tips cause, and it creates a seal that keeps the earbud gripped in place instead of slipping out mid-commute or mid-workout.
In my opinion, the most interesting part is what that seal does for sound. A tighter in-ear seal means more background noise stays out and more bass and clarity stay in, so you can listen at lower volumes and still hear detail. If your problem is "my earbuds leak noise and I keep turning them up," this addresses the root cause rather than just adding volume.
Who should buy it? Owners of compatible models — the sheet lists Etymotic Research (ER2XR, ER4SR, hf5), ISOtunes Pro (IT-01), Westone, Klipsch and Jays (including Free models) — who want a more comfortable, more isolating fit. Who should skip it? Anyone without compatible earbuds, and anyone expecting a plug they can just pop in and sleep in. This is a tip, not a sleep aid. It also needs a little care: warm water and a soft cloth, and no alcohol-based cleaners or lotions, which can degrade the foam. Always check compatibility before buying.
Scozkc's Sleep Earplugs are a different category of product entirely. These are reusable silicone plugs rated to an SNR of 45dB, which in plain terms means they're engineered to knock down a serious amount of noise — snoring, loud neighbors, airplane engine drone. There's no battery, no app, no pairing. You put them in, the room gets quieter.
The design detail that matters most here is the low-profile, ergonomic shape. It sits flush with the ear rather than sticking out, which is specifically aimed at side sleepers — the people who normally wake up with a sore ear because a plug is pressing into the pillow. Scozkc pairs that with ultra-soft, flexible silicone and a "barely-there" fit claim, plus four pairs of tips in XS, S, M and L so you can dial in an actual seal instead of guessing. A plug that doesn't seal blocks far less noise than its rating suggests, so the size range is doing real work.
They're washable and reusable, which makes them a multi-purpose pick: sleep, travel, concerts, studying, or just managing general noise sensitivity. Who should buy them? Side sleepers, light sleepers, snorers' partners, frequent flyers, and anyone with small ear canals who struggles to get a normal plug to seal. Who should skip them? Anyone who wants to listen to music or take calls — these are for silence, not sound. And if you already own compatible IEMs and only want better isolation from them, the COMPLY route solves that problem more directly.
Side-by-Side: Which Should You Choose?
• Best for pure noise blocking while sleeping → Scozkc Sleep Earplugs. The 45dB SNR rating and flush profile are built for exactly this.
• Best for side sleepers → Scozkc Sleep Earplugs. The low-profile shape is designed to sit flush and avoid pillow pressure.
• Best for fit customization on a plug → Scozkc Sleep Earplugs. Four tip sizes (XS/S/M/L) versus COMPLY's large-only three-pair pack.
• Best for better sound quality and bass → COMPLY 100. The memory foam seal improves isolation and clarity so you can listen at lower volumes.
• Best for travel, concerts and shared spaces → Scozkc Sleep Earplugs. Reusable, washable silicone with no electronics and nothing to charge.
• Best for workouts and commuting → COMPLY 100. The foam grips the ear canal and helps stop buds slipping out during movement.
• Best if you don't own compatible earbuds → Scozkc Sleep Earplugs. COMPLY only fits select Etymotic, Westone, Klipsch, ISOtunes Pro and Jays models.
If you're shopping specifically for noise isolating sleep, I'd buy the Scozkc Sleep Earplugs. In my opinion, the combination of a 45dB SNR rating, four sizes and a flush side-sleeper profile is the more complete answer to "I want to sleep through this." The COMPLY 100 is genuinely excellent — but it's a component, not a solution. It only makes sense if you already own compatible IEMs and want to make them quieter and more comfortable. Check the current price on Amazon for whichever one matches your setup before you commit.
are there earbuds for sleeping
Yes, but they come in two flavors. Passive sleep plugs like the Scozkc Sleep Earplugs are silicone and rated to 45dB SNR with a flush, side-sleeper-friendly shape. Foam tips like the COMPLY 100 aren't earbuds on their own — they replace the tips on compatible in-ear monitors to improve isolation and comfort.
what are the best noise cancelling earbuds for sleeping
"Best" depends on what you need. For pure quiet, the Scozkc Sleep Earplugs offer a 45dB SNR rating and four tip sizes. For listening in bed, the COMPLY 100 improves the seal, isolation and bass on compatible Etymotic, Westone, Klipsch, ISOtunes Pro and Jays models. In my opinion, match the product to whether you want silence or sound.
can you sleep with noise cancelling earbuds
You can, but comfort decides whether it actually works. The Scozkc Sleep Earplugs are explicitly designed for side sleepers with a low-profile shape that sits flush, which is the main reason sleep-specific plugs exist. The COMPLY 100 can help compatible IEMs stay put and seal better, but whether you can sleep in those earbuds depends on the earbuds themselves.
is it bad to sleep with noise cancelling earbuds
Not inherently — the real risks are fit and pressure, not the concept. A plug that doesn't seal or that presses into your ear all night is the problem, which is why Scozkc includes XS/S/M/L tips and a flush design, and why COMPLY's memory foam molds to your canal. Follow the care instructions: clean foam tips with warm water and a soft cloth and avoid alcohol-based cleaners.
