MSHUKCOE SK35

The MSHUKCOE SK35's killer feature is connecting each earbud to a different device, a rare and genuinely useful trick. But sound quality is in the bottom third of our database, and the smaller sleep buds barely last two hours. It's a niche pick for dual-device users and side sleepers, not an all-arounder.

Let's be blunt: these aren't for music lovers. The dynamic drivers put the SK35 in the bottom third of our database for sound, so you're getting passable audio for podcasts or calls, not a rich listening experience. Connectivity is where things get interesting. Bluetooth 5.4 puts it in the 84th percentile for wireless performance, and the connection is snappy and stable. The active noise cancellation is above average at the 75th percentile, which helps for calls, though the physical isolation from the in-ear fit does a lot of the heavy lifting. The mic quality is decent at the 71st percentile, and the noise cancellation on calls works well enough in a busy room. Touch controls are responsive, with the brand claiming an 18.5% accuracy bump over older chips, and we didn't run into many misfires.

Stacked against the Sony WF-C700N, the SK35 gets smoked on sound and battery but wins on the dual-device party trick. The Soundcore P31i offers far better audio and a more polished app experience for a similar price. If you're looking at the Nothing Ear (3) or EarFun Air Pro 4+, you're getting massively better sound and ANC performance, though neither can split their buds between two devices. The Samsung Galaxy Buds3 Pro are in a different league entirely for music and calls, but they're also a single-purpose set. The SK35's only real edge is that sleep-and-sports versatility, and you have to really need that to pick it over any of these competitors.

Pricing is all over the map for this one, with a spread from $40 to an eye-watering $1049 across vendors. At the low end, you're getting a unique dual-bud setup with solid connectivity and a handy charging case, which feels like a fair deal for a niche gadget. But if you're seeing it anywhere near the upper end of that range, walk away. The sound and battery performance simply don't justify a premium price tag, and you're firmly in flagship territory from Sony or Samsung at that point.

The MSHUKCOE SK35 is a quirky two-in-one kit that gives you a pair of ultra-slim sleep earbuds and a set of short-handle sports earphones in the same case. The standout feature is the dual-device connectivity, which lets you pair each bud to a different phone or laptop, a genuinely useful trick we don't see often. Comfort is solid, landing in the 74th percentile, and the tiny 0.1oz sleep buds are practically invisible once they're in. But the numbers tell a mixed story. Sound quality sits at a disappointing 31st percentile, and battery life is a real weak spot at the 24th percentile, with the smaller buds struggling to hit even two hours in real-world use.

If you care about sound quality or need earbuds that last through a full workday, keep scrolling. The SK35's audio is in the bottom third of our database, and the battery life is one of the worst we've seen. Anyone who wants a single pair of great all-purpose earbuds will be much happier with the Sony WF-C700N or EarFun Air Pro 4+. And if you're not specifically going to use the dual-device trick, there's no reason to put up with the compromises here.

The MSHUKCOE SK35 is a niche product that nails its specific use case. If you need a set of earbuds where one bud connects to your work laptop and the other to your personal phone, or you want a dedicated sleep pair that won't wake your partner, this is a clever solution. Just know you're trading away sound quality and battery life to get it. The tiny sleep buds dying after a couple of hours is a real frustration, and the audio is strictly functional. For the right person at the right price, it's a handy tool. For everyone else, it's a pass.
