How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want reusable soft silicone sleep earbuds with a proper multi-size fit and a genuinely low-profile shape, choose OEDOC Silicone Ear Plugs; if you need mouldable wax-style plugs with a big pack and real water protection for swimming, choose Mobi Lock Ear Plugs. That's the short version, and it holds up whether you're blocking snoring at 2 a.m., studying, flying, or trying to tame wind noise on a motorcycle.
• OEDOC's biggest strength: reusable soft silicone with 16 ear tips across XS, S, M and L, so you can actually dial in a fit instead of squeezing one generic blob into your ear.
• OEDOC's biggest trade-off: it's a fixed-shape plug, so you're depending on tip sizing rather than moulding the material to your ear.
• Mobi Lock's biggest strength: mouldable silicone wax that contours to your ear, plus a 32dB noise reduction rating and waterproof performance that makes it a genuine swim plug.
• Mobi Lock's biggest trade-off: 30 plugs in one shape — no size options, and wax-style plugs are generally more of a consumable than a long-term keeper.
• Pick OEDOC if you want soft silicone sleep earbuds you can wash and reuse night after night.
• Pick Mobi Lock if you want a big pack of mouldable plugs that also survive the pool, the beach and the shower.
OEDOC is built around one idea: a soft silicone plug that disappears in your ear. The design is ultra-small and ultra-thin, with a right-sized centre shaped around the human ear and the pinna, so it sits in the ear rather than bulging out of it. That matters if you sleep on your side. A plug that sticks out presses into the pillow, and by 3 a.m. you're awake again. OEDOC's whole pitch is that you feel nothing, you can toss and turn, and the plug stays put.
The sizing story is the real differentiator. You get 16 ear tips in XS, S, M and L, plus two travel boxes. That's four chances to find the size your ear actually wants, and a spare set for a bag or a bedside drawer. Noise reduction is rated up to 33dB, which is the kind of figure that covers snoring, a partner's TV, traffic outside the window, a noisy hotel, a long flight, study sessions and loud venues. There's no assembly — you wash them and reuse them, which is what you want from a plug you'll wear most nights.
Who should buy it: side sleepers, light sleepers, frequent flyers, students, and anyone who wants reusable soft silicone sleep earbuds with a proper size range. If you're chasing the best clip on earbuds for motorcycle use or a set of wireless neckband headphones for motorcycle riding, this isn't that — it's a passive plug, not an audio device, and I'd rather you know that up front.
Who should skip it: swimmers who need water protection (that's not what this plug is for), and anyone who prefers to mould the material themselves rather than pick a tip size. If your ear canals are unusually shaped and no standard tip has ever worked, mouldable wax is the smarter route.
Mobi Lock takes the opposite approach. Instead of sizing tips, it gives you mouldable silicone wax that you shape to fit your own ear. The material contours and sits snugly, and because it's soft — the brand compares it to a pillow — it shouldn't cause pain or irritation, and it contains no materials that can irritate skin. If you've ever had a rigid plug ache after an hour, that's the problem this design is solving.
Two specs stand out. First, a 32dB noise reduction rating, which is right in the same territory as the OEDOC figure and plenty for sleeping, travel, concerts, study and general hearing protection. Second, waterproof performance: these double as swimmer's ear plugs, keeping water from clogging your ears at the pool, the beach or the surf. That's a use case OEDOC simply doesn't cover, and it's the strongest reason to pick Mobi Lock.
The pack is 30 reusable plugs in a portable plastic case that shields them from dirt — practical if you want a pair in the car, a pair in a gym bag, a pair at a desk and a pair by the bed. The trade-off is that there's only one shape. If mouldable wax doesn't seal well in your ear, there's no XS or L to fall back on. And wax-style plugs tend to pick up lint and lose their tack over time, so treat them as something you'll work through rather than a buy-once item.
Who should buy it: swimmers, surfers, beach and pool regulars, people who've never had luck with fixed-size tips, and anyone who wants a bulk supply they can scatter across bags and rooms.
Who should skip it: anyone who wants a washable, reusable plug with a defined size system, and anyone who wants a low-profile plug for side sleeping specifically — the moulded wax sits differently than a thin silicone tip.
• Best for side sleeping → OEDOC Silicone Ear Plugs. The ultra-thin, ultra-small design and ergonomic pinna-shaped body are aimed squarely at lying on your side without the plug digging in.
• Best for fit options → OEDOC Silicone Ear Plugs. 16 tips across XS, S, M and L beats a single mouldable shape if your ears are picky.
• Best for swimming and water → Mobi Lock Ear Plugs. Waterproof performance is the one thing OEDOC doesn't offer at all.
• Best for noise reduction figure → a near tie. 33dB for OEDOC versus 32dB for Mobi Lock — close enough that fit will decide which one actually blocks more for you.
• Best for a bulk supply → Mobi Lock Ear Plugs. 30 plugs in a portable case versus OEDOC's 16 tips and two travel boxes.
• Best for custom contour → Mobi Lock Ear Plugs. Silicone wax moulds to your ear; OEDOC asks you to find the right tip instead.
• Best for washing and long-term reuse → OEDOC Silicone Ear Plugs. Washable silicone holds up better than wax as a repeat-use plug.
• Best for travel kits → OEDOC Silicone Ear Plugs. Two compact travel boxes make more sense in a carry-on than a single larger case.
In my opinion, OEDOC Silicone Ear Plugs are the better buy for most people reading this. The size range, the washable soft silicone and the thin side-sleeping profile are exactly what reusable soft silicone sleep earbuds should be, and 33dB covers snoring, flights, study and loud venues. I'd pick Mobi Lock only if water is part of your routine — swimming, surfing, the pool. And to be clear about the motorcycle angle: neither of these is an audio product, so if you're hunting the best gaming headphones for motorcycle helmet use or a wireless neckband set for riding, you're shopping in the wrong category. For blocking wind and engine drone under a helmet, though, a plug like the OEDOC is the right tool.
how to put on silicone earbuds
For a tip-style plug like OEDOC, roll the tip slightly, reach over your head with the opposite hand and pull your ear up and back to straighten the canal, then insert and hold for a few seconds while it settles. Try sizes until one seals without pressure. For Mobi Lock's wax plugs, warm the material in your fingers first, then mould it over the ear opening until it seals.
what are the best earbuds to sleep in
In my opinion, the best sleep plug is the one that stays comfortable when you roll onto your side. OEDOC's ultra-thin silicone design and four tip sizes (XS, S, M, L) are built for that. Mobi Lock's mouldable wax is soft and contours well, but it's a different feel — some sleepers love it, some prefer a shaped tip.
are there earbuds for sleeping
Yes — both of these are passive ear plugs rather than audio earbuds, and both are marketed for sleeping. OEDOC is rated up to 33dB with reusable silicone tips; Mobi Lock is rated 32dB with mouldable silicone wax. Neither plays music, so don't buy either expecting sound.
do these ear plugs work for swimming
Only Mobi Lock does. Its waterproof design is specifically meant to keep water out at the pool, beach or surf. OEDOC's silicone tips are for noise reduction, not water protection, so I wouldn't rely on them in the water.
