How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an everyday open-ear Bluetooth headphone for running, cycling and calls, choose POLVCDG Bone Conduction Headphones; if you need a bone conduction headphone you can actually wear in the pool, choose Laoziniu Bone Conduction Swimming.
That is the whole decision in one line. The two products look similar in photos — both are open-ear, bone conduction designs with a wraparound frame — but they are built for two different jobs. One is a general-purpose sport headphone with a mic and Bluetooth audio. The other is a swim-first device with built-in memory so it can play music with no phone and no wireless signal underwater. Pick the wrong one and you will be disappointed for a very specific reason: one of them is explicitly not made for water.
• POLVCDG Bone Conduction Headphones — biggest strength: true everyday wireless listening with a microphone, ENC call noise reduction, 16mm drivers and up to 10 hours of playback on a single charge.
• POLVCDG Bone Conduction Headphones — biggest trade-off: it is IPX6, which handles sweat and rain but is not a swimming headphone and is not suitable for use underwater.
• Laoziniu Bone Conduction Swimming — biggest strength: IPX8 waterproofing plus 32GB of built-in memory, so you can listen in MP3 mode while swimming without carrying a phone or relying on Bluetooth underwater.
• Laoziniu Bone Conduction Swimming — biggest trade-off: its real focus is the water; for pure everyday Bluetooth features like call noise reduction, the POLVCDG is the more complete wireless headset.
• Who each pick is for: POLVCDG for runners, cyclists, gym users and commuters who want one wireless headphone for everything dry; Laoziniu for swimmers and pool trainers who need music in the water first.
The POLVCDG is the more conventional product of the two, and that is a compliment. It is a Bluetooth 5 open-ear headphone with a flexible titanium frame coated in a skin-friendly material, and it weighs just 29 grams. That combination matters more than it sounds. Open-ear bone conduction already keeps your ear canals unobstructed, which gives you 360° environmental awareness while you run or ride. The light frame is what makes that awareness usable for an hour instead of ten minutes.
Buy it if you want a single lightweight wireless headphone for running, cycling, hiking, gym work, skiing and commuting — and you want to answer calls without digging out your phone. Skip it if you plan to swim. The IPX6 rating is real protection against sweat and rain, but the manufacturer is clear that this is not a swimming headphone and is not suitable underwater. No amount of careful towel-drying changes that. If the pool is the point, this is the wrong tool.
One more thing worth being honest about: the listing describes the color as "White" in the title and the design fields list "Orange White," so if color matters to you, confirm what you are actually getting before ordering. And the "built-in media: CD" field is clearly a data-entry oddity — treat this as a Bluetooth headphone with an aux-free design, nothing more.
Laoziniu Bone Conduction Swimming: Who It's For
The Laoziniu is built around one problem: how do you listen to music underwater when Bluetooth does not travel through water? The answer here is a built-in 32GB MP3 player. You load your songs into memory, switch to MP3 mode, and swim without a phone and without a wireless connection. That single feature is the reason this product exists, and it is the reason a swimmer should not simply buy a cheaper dry-land headphone instead.
The second pillar is the IPX8 rating. Where IPX6 shrugs off sweat and rain, IPX8 is the level designed for pool training and water workouts. The frame is a lightweight wraparound design — 30 grams total — made of silicone, with an open-ear bone conduction driver that keeps your ears free and your surroundings audible. Laoziniu also says the frame can be bent and folded to follow the curve of your head and is easy to carry, which is the kind of detail that matters when the headphone lives in a swim bag.
Away from the water it behaves like a normal sport headphone: switch to Bluetooth mode for running, walking, cycling, gym sessions and commuting. Charging is via a magnetic cable, with a 2-hour full charge giving up to 10 hours of use. Note that the description mentions IP66 in one place while the main feature callout says IPX8 — the IPX8 claim is the one tied specifically to swimming, so if pool use is your reason for buying, that is the spec to hold them to.
Side-by-Side: Which Should You Choose?
• Best for swimming → Laoziniu Bone Conduction Swimming. IPX8 plus 32GB of built-in memory is the only combination here that works underwater.
• Best for calls → POLVCDG Bone Conduction Headphones. ENC call noise reduction and an onboard mic are listed on the POLVCDG; the Laoziniu data sheet does not describe call noise reduction.
• Best for battery and charging convenience → POLVCDG Bone Conduction Headphones. Up to 10 hours on a Type-C fast charge, versus up to 10 hours on a 2-hour magnetic charge.
• Best for audio hardware detail → POLVCDG Bone Conduction Headphones. It specifies 16mm drivers and a 200 Hz–2000 Hz range; the Laoziniu sheet does not publish driver size or frequency range.
• Best for phone-free listening → Laoziniu Bone Conduction Swimming. The 32GB MP3 mode removes the phone and the wireless link from the equation entirely.
• Best for sweat and rain only → POLVCDG Bone Conduction Headphones. IPX6 is plenty for running, cycling, skiing and gym work — just not for immersion.
• Best for fit flexibility → a toss-up. Both use a bendable wraparound frame at roughly the same weight, 29 g for the POLVCDG and 30 g for the Laoziniu, with the Laoziniu using silicone and the POLVCDG using a coated titanium frame.
• Best for a gift → POLVCDG Bone Conduction Headphones. The listing positions it as a birthday gift for women, men and kids; the Laoziniu reads as a specialist swim-training tool.
In my opinion, most people asking this question should buy the POLVCDG Bone Conduction Headphones. It is the better all-rounder: Bluetooth 5, a real microphone with ENC noise reduction, 16mm drivers, 10 hours of battery, Type-C fast charging and a 1-year manufacturer warranty, all in a 29-gram open-ear frame. If your sports are running, cycling, hiking or the gym, this is the one that fits your week.
I would only send you to the Laoziniu Bone Conduction Swimming if swimming is genuinely part of your routine. If it is, the IPX8 rating and the 32GB MP3 player make it the only sensible choice between these two — and the Bluetooth mode means it still works for your dry-land days. Buy the Laoziniu for the water, the POLVCDG for everything else. Check the current price on Amazon for whichever one matches your training, since pricing moves and the button on this page will show you today's figure.
The Laoziniu Bone Conduction Swimming, without question. It is rated IPX8 and has a 32GB built-in MP3 player so it can play music with no Bluetooth signal underwater. The POLVCDG is IPX6 and the manufacturer states plainly that it is not a swimming headphone and is not suitable for use underwater.
Yes. It has a Bluetooth mode specifically intended for running, walking, cycling, gym workouts, commuting and everyday listening when you are not underwater. So it is a two-mode headphone: MP3 mode for the pool, Bluetooth mode on land.
The POLVCDG lists a microphone with ENC call noise reduction for clear audio in noisy environments. The Laoziniu data sheet does not describe a call noise-reduction feature, so if taking calls mid-workout matters to you, the POLVCDG is the safer bet.
Both are close on weight — 29 grams for the POLVCDG and 30 grams for the Laoziniu — and both use a bendable wraparound frame. The POLVCDG uses a flexible titanium frame with a skin-friendly coating; the Laoziniu uses silicone. Which feels better over two hours is a personal fit question, but neither should feel heavy.
Then there is no real contest — take the POLVCDG Bone Conduction Headphones. You get the microphone, the larger specified drivers, the Type-C fast charging and the warranty, and you give up nothing you would actually use.
