If you want a single pair of wireless earbuds that can actually carry you through a full night and into your morning commute, choose Ertuly T33; if you need the strongest possible passive noise blocking with zero batteries, zero charging and zero pairing, choose TOAPEX 45dB.
These two products get lumped together because both promise "quiet for side sleepers," but they solve the problem in completely different ways. One is a tech product. One is a physical barrier. Figuring out which camp you belong to is 90% of the decision.
• Ertuly T33 — biggest strength: Active noise cancellation rated to neutralize up to 98% of disruptive sound, plus 8 hours of playback per charge and 48 hours total with the case, so it doubles as a real set of everyday earbuds.
• Ertuly T33 — biggest trade-off: It's a battery device. You have to charge it, keep track of the case, and accept that ANC is electronics — not a sealed physical plug.
• TOAPEX 45dB — biggest strength: Up to 45dB of passive noise reduction with no battery, no Bluetooth, no pairing, and 8 pairs of silicone tips (XS through L) so you can fine-tune the seal.
• TOAPEX 45dB — biggest trade-off: It does one job. No audio, no calls, no transparency mode — it just blocks sound, and how well it works depends entirely on how well it fits your ear canal.
• Who Ertuly T33 is for: People who want sleep earbuds that also handle calls, music and travel — and who don't mind charging them.
• Who TOAPEX 45dB is for: People who want maximum isolation with zero maintenance, plus concert-goers and travelers who need hearing protection rather than entertainment.
The T33 is built around a hybrid ANC system that uses dual microphones to actively cancel noise — the spec sheet puts that at up to 98% of disruptive sound, with snoring, traffic and appliance hum called out specifically. That's an active approach: the earbuds are listening to your room and generating counter-noise. A triple-tap flips you between ANC and Transparency Mode, which matters more than it sounds. If you sleep with earbuds but still need to hear an alarm, a baby monitor or a partner, being able to open the "window" without pulling the buds out is a genuinely useful trick.
Comfort is where the design gets interesting for side sleepers. The buds are ultra-thin and around 3 grams each, which is the number that matters when your head is pressed against a pillow for seven hours. There's also a dedicated Sleep Mode — four quick taps mutes all alerts and disables touch controls, so you don't accidentally pause your audio or reject a call by rolling over. Anyone who has woken up to their own ear touching a control panel at 3 a.m. will understand why that feature exists.
Who should buy it: side sleepers who want one device for sleep, calls, travel and workouts, and who value ANC plus a transparency mode they can toggle.
Who should skip it: anyone who doesn't want to manage charging, or who wants the absolute maximum isolation a physical plug can give. ANC is impressive, but it isn't a sealed silicone barrier.
TOAPEX 45dB: Who It's For
The TOAPEX is a different philosophy entirely. There's no chip, no battery, no app — just ultra-soft silicone molded into a 3D ergonomic shape that seats into your ear canal and physically blocks sound. TOAPEX rates the multi-layer insulation design at up to 45dB of reduction. That's a big number, and it's the kind of isolation that comes from a proper seal rather than from electronics. Nothing to charge means nothing to run out of at 4 a.m.
The fit story is the real selling point. You get 8 pairs of eartips spread across XS, S, M and L, and TOAPEX claims the range fits about 95% of ear shapes. If you've ever bought earplugs that felt like they were slowly prying your ear open, the pitch here — soft silicone that reduces pressure whether you're tossing or side-sleeping — is aimed squarely at you. A good seal is also what actually delivers the rated reduction. A loose plug is just a lump of silicone.
What makes these more versatile than plain foam plugs is the acoustic filtering. TOAPEX describes intelligent frequency filtering that knocks down harsh, fatiguing sound while keeping music intelligible. That's why the same product is pitched at both sleepers and concert-goers: at a show you want the volume tamed without the music turning to mush, and on a plane you want engine drone and cabin pressure discomfort handled. Sleep, snoring, motorcycling, shooting, musicians — the use list is long because the mechanism is simple.
Maintenance is minimal. They're reusable, washable, and TOAPEX says they can last months or even years, so you're not rebuying disposables. A mini storage case keeps them clean and pocketable, and the matte finish with metallic plating keeps them looking tidy rather than clinical.
Who should buy it: anyone who wants maximum noise blocking with no charging, no pairing and no failure modes — especially people who've struggled to find earbuds that don't hurt.
Who should skip it: anyone who needs audio, calls or a transparency mode. The TOAPEX blocks sound; it doesn't play it or let it through on demand.
• Best for total noise blocking → TOAPEX 45dB. Up to 45dB of passive reduction from a proper seal beats what an active system can do when it has nothing to amplify against.
• Best for battery-free reliability → TOAPEX 45dB. No charge, no case to remember, no dead buds at 2 a.m.
• Best for all-night audio → Ertuly T33. 8 hours per charge covers a full night, and 48 hours total means you're charging the case, not the buds, most of the week.
• Best for side sleepers who want tech → Ertuly T33. Roughly 3-gram ultra-thin buds plus a Sleep Mode that locks out accidental touches is a thoughtful combination.
• Best for calls and work → Ertuly T33. ENC mics, Bluetooth 6.0 and single-or-dual bud flexibility make it a genuine everyday earbud.
• Best for workouts and weather → Ertuly T33. IPX6 sweat and water resistance; the TOAPEX is designed for dry, clean use.
• Best for concerts and loud events → TOAPEX 45dB. Frequency filtering aims to cut volume while keeping music clear, which is exactly the concert use case.
• Best for fit flexibility → TOAPEX 45dB. 8 pairs of tips across four sizes versus the T33's included soft tips.
• Best for travel → depends. The T33 gives you audio and ANC on the plane; the TOAPEX gives you pressure relief and isolation with nothing to charge.
If I had to pick one, I'd buy the Ertuly T33 — but only because I want my sleep earbuds to earn their keep during the day too. ANC, Transparency Mode, 48 hours of total playtime, IPX6 and call handling in one ~3g package is a lot of capability for a single device, and Sleep Mode shows the design was actually thought through for people who sleep on their side.
That said, I'd recommend the TOAPEX 45dB without hesitation to anyone whose priority is pure isolation and zero maintenance. If your problem is a snoring partner, a noisy flight or a loud venue — and you don't need music or calls — the passive approach is simpler, tougher and effectively foolproof. Check the current price on Amazon for both before you commit, since the value math shifts depending on what you already own.
FAQ
Both are designed for side sleepers, but differently. The T33 relies on ultra-thin ~3g buds and a zero-pressure shape plus Sleep Mode to stop accidental touches. The TOAPEX relies on soft silicone and 8 tip sizes for a low-pressure seal. If you want audio, go T33; if you want pure blocking with no bulk, go TOAPEX.
Yes — the T33 offers up to 8 hours of playback per charge, which covers a typical night. The case extends total playtime to 48 hours, and a full recharge takes about 1.5 hours over USB-C.
They're reusable, washable and designed to last months or even years with minimal maintenance, according to TOAPEX. That makes them a long-term alternative to disposable foam plugs — just keep them clean and store them in the included mini case.
If you truly only need silence and never want to think about charging, the TOAPEX 45dB is the simpler, more reliable pick. If you'd rather have one device that also handles music, calls and travel, the Ertuly T33 is the better fit.
