How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of open-ear, bone-conduction headphones that survive full submersion in the pool and carry their own music library, choose SAMVEK Swimming Headphones Underwater; if you need tiny in-ear buds that hush a snoring partner and let you sleep on your side without ear pain, choose Kinglucky Sleep Earbuds. These two look like they belong in the same shopping cart, but they solve opposite problems. One is built for movement and water. The other is built for stillness and silence. Read on and you'll know which one is actually yours.
• SAMVEK's biggest strength: IP68 waterproofing plus 32GB of built-in storage, so you can swim laps with music and no phone anywhere near the water.
• SAMVEK's biggest trade-off: Bluetooth simply won't work underwater — you must switch to MP3 mode in the pool — and there's no noise cancelling at all.
• Kinglucky's biggest strength: Up to 50dB of hybrid noise cancellation with dedicated Sleep Mode, built around side-sleeper comfort and a 50-hour total playtime with the case.
• Kinglucky's biggest trade-off: It's a sleep-and-focus tool, not a sports headphone — no waterproofing rating is given, so I wouldn't take it near a pool.
• Pick SAMVEK if your workouts are wet, sweaty, or outdoors and you want your ears open to traffic and lane mates.
• Pick Kinglucky if your battlefield is a noisy bedroom, a long flight, or a shared office and you want the world to disappear.
The SAMVEK is an open-ear, bone-conduction headphone with an IP68 water and dust resistance rating. That rating is the whole point: it's designed to handle pool workouts and open water, not just a splash of rain. The hook-style fit sits over your ear rather than inside it, so your ear canal stays open and you keep hearing what's around you. For swimming in a public lane or cycling on a road, that awareness matters more than isolation.
The second headlining feature is the 32GB of built-in memory, which SAMVEK says holds up to 8,000 songs. This is why the headphone can work as a standalone MP3 player. SAMVEK is upfront about the catch: Bluetooth signals don't travel through water, so you're meant to use MP3 mode while swimming and save Bluetooth 5.4 for land. On dry ground you get fast pairing and a stable connection with roughly a 10-metre range.
At 32g it's genuinely light for a hook-style headphone, and the ABS/PC build with a Jet Black finish is clearly aimed at everyday training rather than fashion. Battery life is quoted at 8 hours with a 2-hour charge over magnetic charging, and controls are simple push buttons — handy with wet hands, since there's no touch surface to misread. Bone conduction means audio quality leans toward clear speech and detail rather than thumping bass, and there's no noise cancelling here by design.
Buy it if you swim, cycle, or run and want music without blocking your ears or carrying a phone into the water. Skip it if you want deep bass, active noise cancelling, or a headphone for lying on your side in bed — the open-ear hook and button controls are the wrong shape for pillow use.
The Kinglucky is a different animal entirely. These are miniature in-ear buds — Kinglucky quotes a 2.5g figure in the title and 3.0g in the feature text, and either way they're described as about 17% lighter than the average — with a polished silicone contact surface shaped for side sleepers. If you've ever woken up with a sore ear from a normal earbud pressing into the pillow, that's the exact problem this design targets.
Noise handling is the core selling point. Kinglucky describes a triple-layer approach: silicone tips physically block sound like earplugs, AI sorts incoming noise by frequency, and active cancellation handles the rest, with a lab-tested peak of 50dB. Put plainly, that's the difference between a busy coffee shop and a library. There are three modes — Sleep Mode (which suppresses notifications entirely), ANC Focus Mode for work or study, and Transparency Mode so you can hear a colleague or a announcement without pulling the buds out. Three taps switch between them.
The companion app adds 60 tuned sleep sounds, from rain to ocean waves, and lets you save three favourites for one-tap playback, plus a timer so playback stops on its own. Bluetooth 6.0 handles the connection, USB-C fast charging fills the buds in about 1.5 hours, and you get 7–10 hours per charge with a 50-hour total from the case. A smart LED display on the case shows the remaining battery for both buds and case, which quietly solves the "low battery beep at 2am" annoyance.
Buy it if you're a light sleeper, share a bed with a snorer, travel a lot, or need to concentrate in a noisy room. Skip it if you want headphones for swimming or heavy sweating — no water-resistance rating is stated — or if you prefer to keep an ear open to your surroundings at all times.
Side-by-Side: Which Should You Choose?
• Best for swimming and water sports → SAMVEK. IP68 waterproofing and an MP3 mode built specifically for underwater listening.
• Best for sleep and side sleeping → Kinglucky. Ultra-light in-ear design with a silicone contact surface made for pillow pressure.
• Best for staying aware of your surroundings → SAMVEK. The open-ear, bone-conduction design leaves your ear canal unobstructed.
• Best for battery endurance across a day or night → Kinglucky. 7–10 hours per charge and 50 hours total with the case, against 8 hours on the SAMVEK.
• Best for leaving your phone behind → SAMVEK. 32GB of internal storage means the music lives on the headphone itself.
• Best for focus at a desk or on a plane → Kinglucky. Focus Mode plus transparency switching makes it a work tool as much as a sleep tool.
• Best for simple, gloved or wet-hand control → SAMVEK. Physical push buttons beat touch controls when your hands aren't dry.
In my opinion, most people searching these two names already know which camp they're in — and if you're not sure, ask yourself one question: do I want to hear less, or do I want to hear more? If you want less noise and better sleep, I'd buy the Kinglucky Sleep Earbuds. The 50dB cancellation, side-sleeper fit, app sounds, and 50-hour case life make it a genuinely specialised sleep tool rather than a compromise. If you want music in the water with your ears still open to the world, I'd buy the SAMVEK — its IP68 rating and 32GB of onboard storage are features the Kinglucky simply doesn't attempt, and no sleep bud can replace them. Check the current price on Amazon before you commit, since both sit in very different budget brackets.
FAQ
There's no waterproof or water-resistance rating listed for the Kinglucky, so I wouldn't risk it. It's designed for dry environments — beds, desks, planes and commutes. For water, the SAMVEK is the one with the IP68 rating.
Partly. The silicone tips act as physical earplugs on their own, which is the passive-isolation layer. For the full effect, including the lab-tested 50dB peak, the active cancellation needs to be switched on.
The Kinglucky, clearly. It's built around an ultra-light in-ear body with a soft silicone contact surface specifically for people who sleep on their side. The SAMVEK's open-ear hook design sits outside the ear and isn't intended for pillow use.
Kinglucky lasts longer overall — 7–10 hours per charge plus a charging case for 50 hours total, versus 8 hours on a single SAMVEK charge. If you need one continuous session rather than a full night or multiple days, the difference is smaller than it looks.
