How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a moldable, doctor-trusted putty plug that seals water and noise out of any ear shape, choose Mack's Pillow Soft Silicone; if you need tiny wireless earbuds that stay hidden in small ears and let you take calls and play music while lying on your side, choose Xmenha Tiny Hidden.
• Mack's Pillow Soft Silicone — biggest strength: moldable silicone putty that adapts to any ear contour, with a 22 dB NRR (US) and 30 dB SNR (EU) rating, plus waterproof protection for swimming and bathing.
• Mack's Pillow Soft Silicone — biggest trade-off: it's a passive plug, not a device. No music, no calls, no Bluetooth — just blocking sound.
• Xmenha Tiny Hidden — biggest strength: genuinely mini wireless Bluetooth earbuds (0.1 oz each) built for small ears, with touch controls, auto-pairing, and a low-profile fit that works for side sleepers.
• Xmenha Tiny Hidden — biggest trade-off: the noise control is sound isolation via ear tips, not active noise cancellation, so it won't match a sealed putty plug for blocking loud environments.
• Who Mack's is for: sleepers, swimmers, concert-goers, flyers, and anyone who wants maximum noise and water blocking without electronics.
• Who Xmenha is for: people with small ear canals who want invisible earbuds for music, calls, work, and side-sleeping comfort.
Mack's Pillow Soft Silicone is the putty-style earplug that you roll into a ball and press over your ear canal. Because it molds to the unique contours of any ear, it doesn't rely on fitting inside the canal the way foam or flanged plugs do — it seals the opening instead. That's the core of its appeal: a comfortable, custom-feeling fit without jamming anything deep into your ear. It carries a Noise Reduction Rating of 22 decibels under the US standard and a 30 dB SNR under the EU standard, which tells you it's built for real-world noise blocking rather than light muffling.
The design is straightforward and non-technical: white silicone, putty style, sold as a 16-count pack (8 pairs). Because it's waterproof, it's a natural fit for swimming, bathing, and showering — the kind of environments where electronics simply don't belong. Mack's markets it for sleeping, snoring spouses, studying, travel, loud events, concerts, flying discomfort, and motorcycling, and the putty form is what makes that range possible. For flying specifically, the moldable seal is designed to help relieve airplane ear pressure and pain.
Buy it if you want a simple, reusable, waterproof plug that blocks noise and water without batteries, pairing, or charging. It's the pick for side sleepers who just want quiet, for swimmers worried about water in the ears, and for anyone sharing a bed with a snorer. Skip it if you want to listen to music, take calls, or use a voice assistant — the putty does exactly one job, and it does it passively.

Xmenha Tiny Hidden is a completely different category of product: a pair of mini wireless Bluetooth earbuds engineered to disappear into small ears. Each bud weighs only 0.1 oz, and the whole point of the design is that they sit almost unnoticeably in the ear — the brand even frames them as doubling as a small decoration rather than obvious headphones. If standard earbuds have always felt bulky or fallen out of your small ear canals, this is the niche they're built for.
Functionally, they're real earbuds with real features. You get stereo HIFI sound from a 10mm diaphragm unit with triple frequency equalization, touch controls on either bud for music switching, volume, calls, and voice assistant, plus one-step auto-pairing — take them out of the case and they reconnect to your last device. The case is compact and pocketable. They're also waterproof and sweat-proof, so workouts and light rain aren't a problem, and the brand describes noise suppression during calls so your voice comes through in noisy settings.
Side-by-Side: Which Should You Choose?
• Best for blocking loud noise → Mack's Pillow Soft Silicone. The 22 dB NRR / 30 dB SNR rating is a measured passive seal; Xmenha's tips are isolation only, not ANC.
• Best for swimming and water → Mack's Pillow Soft Silicone. It's waterproof putty designed for swimming, bathing, and showering. Xmenha is water-resistant electronics, which is a different thing.
• Best for side sleepers → Xmenha Tiny Hidden. The low-profile, 0.1 oz design is made to lie on without pressure. Mack's works too, but it's a plug, not a speaker.
• Best for small ears that reject normal earbuds → Xmenha Tiny Hidden. That's literally its design brief.
• Best for listening to music and taking calls → Xmenha Tiny Hidden. Touch controls, HIFI stereo sound, voice assistant, auto-pairing. Mack's does none of this.
• Best for zero-fuss, no-charging use → Mack's Pillow Soft Silicone. No battery, no pairing, no case — just mold and wear.
• Best for flying → Mack's Pillow Soft Silicone. The moldable seal is designed to help relieve airplane ear pressure and pain.
• Best for discreet audio at work → Xmenha Tiny Hidden. The invisible, skin-tone, low-profile look is the whole selling point.
These two barely overlap, so the honest answer is that most people don't have to choose between them — they solve different problems. If I had to pick one for the average shopper, I'd lean toward Mack's Pillow Soft Silicone, because it does its one job exceptionally well: a moldable, waterproof, measured noise-blocking seal that works in any ear and never needs charging. I'd choose Xmenha Tiny Hidden only if audio is the priority — if you want tiny, discreet Bluetooth earbuds for small ears, calls, and side-sleeping, Mack's can't do any of that. In my opinion, buy the Xmenha if you need sound; buy the Mack's if you need silence.
It provides sound isolation through dual ear tips, which the brand says suits moderate noise. It is not active noise cancellation, so for loud snoring or traffic, Mack's sealed putty with its 22 dB NRR rating will block more.
Yes — it's a waterproof silicone putty designed for swimming, bathing, and showering, and it molds to seal the ear opening. That's a use case where you'd never wear the Xmenha earbuds.
The brand uses an ergonomic in-ear design meant to secure the fit and reduce falling out, and each bud weighs just 0.1 oz. If normal earbuds are too big for you, these are purpose-built for small ear canals.
They're not directly comparable — one is a passive putty plug, the other is a Bluetooth earbud set with a charging case. Decide based on whether you need audio or silence, then check the latest price on Amazon for each.
