• Ururtm's biggest strength: a 100% soft silicone build with no hard plastic to dig into your ear or your pillow, plus passive noise isolation that the spec sheet puts at reducing ambient noise by 70–90% even with no audio playing.
• Ururtm's biggest trade-off: it's wired, so you're tethered to a 3.5mm jack device, and it has no app, no sleep tracking, and no active features beyond the passive isolation.
• WXQZXO's biggest strength: a full smart package — Bluetooth 6.0 wireless, a sleep monitor app with stages and sleep scores, a Sleep Mode that kills notifications, and up to 48 hours total with the charging case.
• WXQZXO's biggest trade-off: the spec sheet lists no noise cancellation at all, so it plays sound but doesn't physically block the room the way the Ururtm does.
• Pick Ururtm if you're a side sleeper who wants a pressure-free plug that muffles snoring and street noise.
• Pick WXQZXO if you want to fall asleep to white noise untethered and wake up to data about how you actually slept.
The Ururtm is built around one idea: make an earbud you can forget is there. The entire housing is soft silicone, and the double-layer eartip design is meant to sit deep enough in the canal to stay put while you roll around. That matters because the main thing that wakes side sleepers isn't sound — it's pressure. A hard plastic shell pressing into a pillow for eight hours is what causes that dull ache. Here, there's no hard shell to press.
The second thing it does well is block sound without any electronics involved. The spec sheet claims 70–90% ambient noise reduction passively, which means it works as an earplug first and a headphone second. If your problem is a partner who snores, a neighbor's dog, or traffic outside the window, that reduction happens whether or not you're playing anything. Pair it with white noise, a sleep app, or an audiobook through the 3.5mm jack and you're layering isolation on top of isolation.
Who should buy it: side sleepers, people who share a bed with a snorer, light sleepers who already like earplugs, and travelers who want something for planes and trains. It ships with a zippered silicone case and a 1-year warranty. Who should skip it: anyone who wants wireless, anyone who wants sleep analytics, and anyone whose phone has dropped the 3.5mm jack — you'd need an adapter, and that's a friction point worth thinking about before you commit.
The WXQZXO takes the opposite approach. Instead of blocking the world out, it curates what you hear and then tells you how the night went. Each bud weighs about 3 grams, which is genuinely tiny, and the tips are soft, skin-friendly silicone that detach — so the part touching your ear can be cleaned or swapped. The buds themselves are ABS and silicone, and the shape is a small circle rather than a stem, which is the design choice that lets them sit flatter against a pillow.
The smart layer is where it separates itself. Sleep Mode shuts off voice assistants, call ringtones, and system notifications so nothing buzzes you awake, and you can schedule playback so audio fades out on its own. The Zemyee Life app pulls from a built-in white noise library and, more interestingly, tracks sleep stages, sleeping positions, and total duration, then rolls it into a score. Over weeks, that's the kind of data that tells you whether your "I slept badly" feeling was real or just one rough night.
On the hardware side you get Bluetooth 6.0 with a stated 15-meter range, up to 8 hours per charge, and up to 48 hours total with the case, topped up over Type-C. Tap controls handle play, pause, and mode switching without you reaching for your phone in the dark. The trade-off is honest: noise control is listed as none. These don't cancel or isolate the room; they replace it with audio. Who should buy it: side sleepers who want wireless, light sleepers who want an app to silence their phone, shift workers, and anyone curious about their own sleep patterns. Who should skip it: people who specifically need to mute a snoring partner without playing anything, and anyone who'd rather not manage an app and a charging case.
Side-by-Side: Which Should You Choose?
• Best for blocking snoring and room noise → Ururtm Sleep Soundproof Earbuds (passive isolation stated at 70–90%, no audio required).
• Best for side sleeping comfort → a tie on paper, but the Ururtm's all-silicone housing and the WXQZXO's 3-gram weight attack the same problem from different angles.
• Best for battery life → WXQZXO Sleep Earbuds (up to 8 hours per charge, up to 48 hours with the case).
• Best for wireless freedom → WXQZXO Sleep Earbuds (Bluetooth 6.0, no cable to tangle at 3 a.m.).
• Best for zero setup and zero charging → Ururtm Sleep Soundproof Earbuds (wired, no battery, no app, no pairing).
• Best for travel and storage → Ururtm Sleep Soundproof Earbuds if you want a simple zippered case; WXQZXO if you want a charging case you can clip to a bag.
• Best for phone calls → WXQZXO Sleep Earbuds (the Ururtm's spec sheet doesn't list a microphone, so don't count on calls).
If I had to pick one, I'd buy the WXQZXO Sleep Earbuds — but only for a specific kind of sleeper. In my opinion, the combination of 3-gram buds, Bluetooth 6.0, a Sleep Mode that silences your phone, and actual sleep tracking makes it the more capable product for someone who wants to fall asleep to audio and learn something about their nights. That said, if your single goal is to mute a snoring partner or street noise without playing anything, I'd point you to the Ururtm instead. Its passive isolation does the job a wireless bud simply can't, and the all-silicone build is the more side-sleeper-friendly design of the two. Match the tool to the problem, not the other way around.
Keep the volume low and use buds designed to sit flat, like these two. The Ururtm's soft silicone housing avoids hard edges against your ear, and the WXQZXO's 3-gram buds and detachable tips are shaped to stay put through the night. Scheduled playback on the WXQZXO also lets audio fade out after you drift off.
Side sleeping is exactly what both of these are built for. The Ururtm gets there by eliminating hard plastic entirely, so nothing presses into the pillow. The WXQZXO gets there through sheer low weight — about 3 grams per bud — plus a small circular shape that sits closer to the ear rather than protruding.
This page doesn't cover Ionix, so I won't guess at its fit. For the two models here: the Ururtm uses a double-layer eartip you seat at a comfortable depth in the canal, and the WXQZXO uses soft silicone tips that follow your ear's contour with tap controls on the bud itself. Both are adult-sized in-ear designs, so start shallow and adjust.
Neither is universally better — it comes down to your priority. Wireless, like the WXQZXO, means no cable to catch on a pillow, plus app features and up to 48 hours with the case. Wired, like the Ururtm, means nothing to charge and passive isolation that works with no audio at all. If price matters to you, check the current price on Amazon for both before deciding.
