If you want a colorful, protective shell for your AirPods 4 that also gives you four different looks in one box, choose XMBYGY Pack Cute Case; if you need a sleep mask that plays sound and blocks light at the same time, choose LC-dolida White Noise.
• XMBYGY Pack Cute Case — biggest strength: you get four silicone cartoon cases plus four carabiners in a single pack, so you can swap skins to match your mood or outfit without buying anything else.
• XMBYGY Pack Cute Case — biggest trade-off: it only fits AirPods 4 (2024). If you own any other AirPods generation, this case simply won't work — the earbuds themselves are also not included.
• LC-dolida White Noise — biggest strength: it merges a blackout 3D sleep mask with built-in speakers, a microphone, and 16 pre-loaded soothing sounds, plus a 3-stage timer and up to 15 hours of playback.
• LC-dolida White Noise — biggest trade-off: it's a single-purpose sleep and travel tool, and it needs charging to run — the Bluetooth module is removable so the mask itself is machine-washable, but you have to manage the battery.
• Who each pick is for: the XMBYGY pack suits AirPods 4 owners who want playful protection and variety; the LC-dolida mask suits side sleepers, travelers, and light sleepers who want audio and darkness together.
The XMBYGY Pack Cute Case does one job and does it thoroughly: it wraps your AirPods 4 charging case in soft silicone and gives you options. The set arrives with four separate cases in different cartoon skins, plus four carabiners. That's the whole pitch — protection, personality, and swapping flexibility. The silicone is described as soft and durable, with an internal surface designed not to scratch the charging station or loosen and deform over long-term use. The charging port is cut out at the bottom, so you can top up your AirPods without pulling the case off. The lid opens and closes by hand, and the whole thing is thin and light enough to disappear in a pocket.
Who should skip it? Anyone who doesn't own AirPods 4. The compatibility list is strict — it's built for the 2024 AirPods 4 earbuds and explicitly not for AirPods 1st or 2nd generation, not for AirPods 3rd generation, and not for AirPods Pro or AirPods Pro 2. And if you want a plain, minimal shell rather than a cartoon look, the whole point of this pack is the skin variety, so you'd be paying for features you don't care about. One more note: the earbuds are not included, so this is purely a cover kit.
LC-dolida White Noise: Who It's For
The LC-dolida White Noise is a different category of product entirely — it's a sleep tool, not a case. The design centers on a deep 3D eye contour that leaves room for your eyes and lashes so nothing presses on them, plus a triangular cutout area over the nasal bridge, which matters if you're congested or just want to breathe freely. A bottom light-blocking strip and full nose bridge coverage are there to stop leakage from any angle, which is the detail that separates a real blackout mask from a thick cloth one.
The audio side is where it gets interesting. Bluetooth 5.4 handles playback and calls within a 10-meter range, and the mask includes both a microphone and speakers. But the feature I find most useful is the dual-mode setup: 16 built-in soothing white noise tracks play without any paired device at all. That means you can put the mask on and get sound immediately — no phone, no app, no setup. There's also a 3-stage timer (30, 90, and 120 minutes) covering a power nap, a meditation session, or a full deep-sleep stretch.
Battery-wise, a 1.5-hour charge is described as fueling 12–15 hours of playback, which is roughly two nights. The control module is removable, so the mask itself is fully machine-washable — a genuinely practical detail for something that sits on your face nightly. The headband is elastic and sized for roughly 20 to 27 inches, with widened Velcro to stop slipping, and the material is soft, breathable, and hypoallergenic. The mask comes in black.
Side-by-Side: Which Should You Choose?
• Best for protecting AirPods 4 → XMBYGY Pack Cute Case. It's built specifically for the 2024 model with precise cutouts and a reserved charging port.
• Best for blocking light and sound together → LC-dolida White Noise. The 3D contour plus bottom light strip targets 100% blockage, and built-in audio covers the noise side.
• Best for variety and gifting → XMBYGY Pack Cute Case. Four skins and four carabiners in one pack make it a ready-made gift set.
• Best for travel and sleep routines → LC-dolida White Noise. Timer modes, 12–15 hours of playback, and a washable mask suit back-to-back nights and long trips.
• Best if you want zero charging to manage → XMBYGY Pack Cute Case. It's passive silicone; there's nothing to plug in.
• Best if you sleep on your side → LC-dolida White Noise. The zero-pressure 3D eye contour and side-sleeping headphone design are aimed squarely at that position.
• Best for a phone-free wind-down → LC-dolida White Noise. The 16 built-in white noise tracks work without pairing anything.
• Best if you don't own AirPods 4 → LC-dolida White Noise. The XMBYGY case won't fit older AirPods or any Pro model, so it's off the table.
My Verdict
These two products barely compete — they solve unrelated problems, so the real question is which problem you actually have. If your AirPods 4 case is scratched, boring, or sliding around in your bag, I'd buy the XMBYGY Pack Cute Case; the four-skin format and carabiners give you more than a single case ever would, and the fit is model-specific. If your problem is falling asleep or staying asleep — light, snoring, noisy hotels — I'd buy the LC-dolida White Noise instead. In my opinion, the mask is the more technically interesting product because it removes the need for a phone entirely, but it only earns its place if you'll actually wear it nightly. Match it to your routine, not to the spec list.
