How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want earbuds that stay sealed in your ears while you swim laps and can plug straight into a waterproof MP3 player, choose Swimbuds Flip Waterproof Short-Cord; if you need one headset that plays music without any phone or player at all and keeps your ears open on land, choose Laoziniu Bone Conduction Headphones.
• Swimbuds Flip biggest strength: IPX8 waterproofing rated to 10 ft, a short cord that cuts drag and tangles, and an in-ear seal built to hold through a full swim.
• Swimbuds Flip biggest trade-off: It's wired with a 3.5 mm jack, so it needs a separate audio source — no Bluetooth, no built-in memory.
• Laoziniu biggest strength: A 32GB MP3 player built into the headset, so you can swim with music and no phone anywhere nearby.
• Laoziniu biggest trade-off: Bluetooth doesn't transmit underwater, so you have to switch to MP3 mode in the pool — and the open-ear bone conduction design leaks sound outward and lets pool noise in.
• Who Swimbuds Flip is for: Swimmers and athletes who already own a waterproof player and want a secure, low-drag wired fit.
• Who Laoziniu is for: Swimmers and runners who want an all-in-one wireless headset with onboard storage and situational awareness.
The Swimbuds Flip is a purpose-built swim earbud, and the design tells you that immediately. The buds sit in your ear at an angle chosen to reduce drag, and the short cord does the same job — less material trailing behind your head means less pull and less chance of a tangle mid-stroke. The "L" jack is there for a reason too: a right-angle connector puts less stress on the cable where it meets the plug, which is exactly where cheap wired buds tend to fail.
The IPX8 rating is the headline. That means submersible indefinitely up to 10 feet, so pool laps, open-water swims, jogging in the rain or a sweaty gym session are all inside its comfort zone. The silicone tree tips come in three sizes, and the point of that shape is sound isolation plus a watertight seal that holds through a whole swim. In my opinion, that seal is the single most important spec here — if water creeps in, the music dies, and the tree-tip design is clearly aimed at preventing that.
Who should buy it? Anyone who already has a waterproof MP3 player or a phone in a waterproof pouch and wants wired buds that won't shift. The included extension cable adds enough length to reach a pocket on land, so it doubles as a normal set for runs and walks. The trade-off is real, though: wired means no Bluetooth, no built-in storage, and a cable to manage. If you want to leave your phone behind entirely, this isn't the one.
The Laoziniu is a different animal. It's an open-ear bone conduction headset, which means nothing goes inside your ear canal — the drivers sit against your cheekbone and send sound through vibration. That keeps your ears free, so you can hear traffic, a training partner or a pool attendant while you listen. For runners and cyclists, that awareness is a genuine safety feature, not a marketing line.
The standout spec is the built-in 32GB MP3 player, which holds roughly 8,000 songs. That matters because Bluetooth doesn't transmit underwater — the manufacturer says so directly, and it's a physical limitation of the technology, not a flaw in this model. So in the pool you switch to MP3 mode and play from onboard memory with no phone involved. Out of the water, Bluetooth 5.3 gives you a stable connection to phones, tablets and laptops within about 33 ft in open space, plus a built-in mic for calls.
Battery life is rated at up to 10 hours with roughly 2 hours to charge, and the whole thing weighs about 30 g with a titanium frame — light enough to forget you're wearing it. The kit includes a magnetic charging cable, sponge earplugs, an adjustment strap and a storage bag. One caveat from the specs: dry the charging contacts completely before charging after water use, and note the IPX8 rating applies to the headset design while the description also references IP66 — so treat it as a swim-capable headset that still needs care around the charging port.
Who should skip it? Anyone who wants deep, isolating sound. Bone conduction leaks audio outward and lets ambient noise in, so in a noisy pool you'll hear the water as much as your playlist. If you want to block the world out, the Swimbuds' sealed in-ear fit is the better match.
Side-by-Side: Which Should You Choose?
• Best for swimming without any phone or player → Laoziniu Bone Conduction Headphones. The 32GB of onboard storage is the entire point.
• Best for battery freedom → Laoziniu Bone Conduction Headphones. Up to 10 hours per charge versus a wired set that draws power from whatever it's plugged into.
• Best for low drag and no tangles → Swimbuds Flip Waterproof Short-Cord. The short-cord design exists specifically to cut drag and cable snarls.
• Best for hearing your surroundings → Laoziniu Bone Conduction Headphones. Open-ear bone conduction keeps traffic and voices audible.
• Best for sound isolation → Swimbuds Flip Waterproof Short-Cord. The silicone tips actively block outside noise; the Laoziniu does the opposite.
• Best for calls and everyday wireless use → Laoziniu Bone Conduction Headphones. Bluetooth 5.3 and a built-in mic make it a daily driver, not just a swim tool.
• Best all-in-one for mixed land and water use → Laoziniu Bone Conduction Headphones, if you can accept the open-ear sound trade-off.
If I had to pick one for most people, I'd buy the Laoziniu Bone Conduction Headphones. The 32GB MP3 player, 10-hour battery, Bluetooth 5.3 and open-ear awareness make it a single device that handles the pool, the run and the commute without extra gear. I'd only steer you to the Swimbuds Flip if a tight, isolating in-ear seal is your priority and you already own a waterproof player to plug into. Both are genuinely IPX8 swim-capable; the decision comes down to whether you want a sealed wired bud or a wireless all-in-one. Check the current price on Amazon before you commit.
FAQ
can i wear waterproof headphones in the shower
Yes, in most cases. The Swimbuds Flip carries an IPX8 rating for submersible use up to 10 feet, and the Laoziniu is also rated IPX8 for pool and water use. Just dry the Laoziniu's magnetic charging contacts completely before charging, since moisture there can affect the battery.
Not all of them — "waterproof" and "water-resistant" aren't the same thing. Both headsets here are rated IPX8, which is a genuine submersible rating rather than a splash-only one. Note that the Laoziniu's description also references IP66 in places, so treat its charging port with care after any water exposure.
No. Bluetooth doesn't transmit underwater, so you switch the Laoziniu to its built-in 32GB MP3 mode, which stores roughly 8,000 songs. That means you can leave your phone in your bag and still have music in the pool.
No. The Swimbuds Flip is a wired headset with a 3.5 mm jack, so it needs a separate audio source such as a waterproof MP3 player or a phone in a waterproof case. Its strength is the watertight in-ear seal and low-drag short cord, not onboard playback.
