• Dulailt Open-Ear Bone Conduction — biggest strength: Bluetooth 5.3 with fast pairing and a charging case that stretches 6 hours of playtime into 30 hours total. Ear-clip design that stays locked during running, hiking and cycling.
• Dulailt Open-Ear Bone Conduction — biggest trade-off: IPX4 only. Sweat and rain are fine; swimming and full submersion are not. No active noise cancellation, and no built-in storage — it always needs a paired phone.
• POLVCDG Swimming Headphones — biggest strength: IPX8 waterproofing rated for submersion up to two meters for one hour, plus 32GB of built-in storage for phone-free MP3 listening and a 10-hour battery.
• POLVCDG Swimming Headphones — biggest trade-off: Bluetooth cannot transmit underwater, so swimming means switching to MP3 mode. The titanium frame is a fixed neckband shape rather than a clip, and the enclosure is plastic and rubber.
• Who each pick is for: Dulailt for the runner, cyclist or gym-goer who wants a lightweight clip-on pair with a battery case; POLVCDG for the swimmer or lap-pool regular who wants music in the water without a phone.
The Dulailt set is built around the ear-clip idea. Instead of a band that wraps behind your neck, each earpiece hooks onto your ear and fires sound through your cheekbones. The open design means nothing enters the ear canal, and Dulailt's own framing is that this avoids ear fatigue even over long sessions. That's the core appeal: you get music and you still hear traffic, footsteps and the people around you.
The battery story is the headline. You get 6 hours of playtime on the buds themselves, and the included wireless charging case pushes that to 30 hours total. For a week of commutes and workouts, that's a genuinely useful buffer — you're not hunting for a cable every evening. Bluetooth 5.3 handles pairing and connection stability, and there's a built-in microphone for calls. IPX4 means sweat and light rain are covered, which matches the running, cycling, gym and rock-climbing use cases Dulailt points at.
Who should buy it: anyone who wants a lightweight, clip-on, open-ear pair for outdoor sport and everyday listening, and who values the charging case more than raw water resistance. In my opinion it also suits people who dislike neckbands, since the clip format stays out of the way when you turn your head. Who should skip it: swimmers, and anyone who wants to leave their phone behind. With no onboard storage and only IPX4, this is a Bluetooth-first product. If you want a no-phone, in-water experience, keep reading.
The POLVCDG pair is a different animal. It's a neckband-style open-ear headphone with a flexible titanium frame coated in skin-friendly material, so it bends to fit different head shapes — and at 32 grams it's light enough that POLVCDG positions it as fatigue-free for long activities. The drivers are 16mm bone conduction units with a 20 Hz to 20,000 Hz frequency range, and there's a microphone with environmental noise cancellation for calls.
Then there's the part that matters most: IPX8. POLVCDG rates these for submersion up to two meters for one hour, which is what makes swimming realistic. The catch is physics — Bluetooth can't travel through water, so you have to use MP3 mode in the pool. That's exactly why the 32GB of built-in storage exists. POLVCDG says it holds over 8,000 songs, so you load your library once and swim phone-free. Battery life is a claimed 10 hours per charge with fast charging, and the controls are volume-based with active noise cancellation listed as the noise-control type.
Who should buy it: swimmers first, but also runners and cyclists who want to leave the phone at home and just carry music on the headset. Who should skip it: anyone who mainly wants to take calls and stream from a phone in the pool — that's not how the underwater mode works — and anyone who prefers a small clip-on form factor over a neckband.
Side-by-Side: Which Should You Choose?
• Best for battery flexibility → Dulailt Open-Ear Bone Conduction. 6 hours plus a charging case equals 30 hours total, versus POLVCDG's 10 hours on a single charge.
• Best for phone-free listening → POLVCDG Swimming Headphones. 32GB of onboard storage and an MP3 mode mean no paired device required.
• Best for a clip-on, no-neckband fit → Dulailt Open-Ear Bone Conduction. The ear-clip design is the lighter-feeling option if you dislike bands behind your neck.
• Best for head-shape adaptability → POLVCDG Swimming Headphones. The flexible titanium frame is explicitly designed to conform to different head shapes.
• Best for calls with noise handling → POLVCDG Swimming Headphones. It lists environmental noise cancellation and active noise cancellation; Dulailt lists no noise control at all.
• Best for pure Bluetooth simplicity → Dulailt Open-Ear Bone Conduction. Bluetooth 5.3, fast pairing, a mic and a case — nothing to load, nothing to switch modes on.
• Best for swimmers who also want open-ear running headphones → POLVCDG Swimming Headphones. One pair covers the pool and the pavement.
For most audiophiles shopping this category, I'd buy the POLVCDG Swimming Headphones. The IPX8 rating plus 32GB of storage is a combination Dulailt simply doesn't offer, and it's the difference between a headphone that survives your workout and one that can actually go in the water with you. Ten hours per charge is plenty for a training week, and the titanium frame plus 16mm bone conduction drivers suggest a more adaptable, fuller-sounding setup on paper. I'd only pick the Dulailt Open-Ear Bone Conduction instead if swimming is off the table and I wanted the clip-on fit with the charging case — the 30-hour total is genuinely convenient, and Bluetooth 5.3 keeps things simple. Check the current price on Amazon for both before you commit, since that's the one variable that can flip this decision.
Is the POLVCDG Swimming Headphones waterproof enough for actual swimming?
Yes — it carries an IPX8 rating and is specified for submersion up to two meters for one hour. Just remember Bluetooth doesn't work underwater, so you'll listen in MP3 mode from the 32GB of built-in storage.
No. It's rated IPX4, which covers sweat and rain, not immersion. For the pool you want the POLVCDG pair and its IPX8 rating.
It depends how you count. POLVCDG gives 10 hours on a single charge with fast charging. Dulailt gives 6 hours per charge but 30 hours total with its charging case, so it wins on cumulative runtime across a week.
