The SilisoundTek IP68 is my top pick for most swimmers — an IP68 rating plus a built-in 32GB MP3 player means it keeps playing when Bluetooth can't follow you underwater, and the 8-hour battery covers a long pool session.
• SilisoundTek IP68 — best for swimming and long training sessions; pick this if you want true underwater playback from a 32GB MP3 mode rather than a Bluetooth signal that dies at the water's surface.
• MASTJUST Bone Conduction Headphones — best for running, gym work and cycling in the rain; pick this if you want a light 24.95 g open-ear set with a flexible titanium band and you never plan to submerge it.
• Generic Swimming Bone Conduction — best for pool swimmers who want the longest claimed runtime; pick this if IP68 protection and a 32GB MP3 mode matter more to you than a familiar brand name.
• essoniox Bone Conduction Headphones — best for gifting and everyday open-ear listening; pick this if you want a titanium-and-silicone build, AI voice control and a proper presentation box.
This is the one I'd hand to someone who swims laps three times a week. The headline spec is IP68, which is the highest water-and-dust protection rating in this group and the reason it's the only set here I'd feel comfortable recommending for actual underwater use. Silicone enclosure, on-ear bone conduction drivers, 20Hz–20,000Hz frequency range, 8 ohm impedance.
The smart part is how it solves the Bluetooth problem. Bluetooth doesn't travel through water — a signal that works fine on the pool deck will cut out the moment your head goes under. So SilisoundTek built in a 32GB memory card that holds something in the region of 8,000 songs. You load your music beforehand, switch to the TF card mode, and the headphones play independently of your phone. That's the whole trick, and it's the right one. You're not fighting physics, you're sidestepping it.
Battery is listed at 8 hours of music or calls, with standby up to 10 days and a full charge in 1.5 hours via magnetic charging. Eight hours is genuinely a lot of swimming. The Bluetooth 6.0 radio reaches about 13 meters and supports multiple paired devices, so you can flip between a phone and a smart watch without re-pairing every time. In daily use that means: pool in the morning on MP3 mode, then Bluetooth on the walk home. The set ships with two charging cables, an adjusting belt, earplugs and a storage bag, and the warranty runs 24 months.
The trade-off is honest and worth stating plainly: this is a swimming-first design. If you mostly want headphones for the gym and have no intention of putting your head underwater, you're paying in complexity — a separate MP3 workflow to manage — for a capability you'll never use. The orange-gray colourway is also a specific look, not a neutral one. For dry-land athletes, the MASTJUST below is the simpler answer.
The MASTJUST Lite is the lightest thing here at 24.95 g, and that number does real work. On a 10K run or a long gym session, weight on the temporal bone is what makes people rip headphones off, and under 25 g is light enough that most people stop noticing it. The headband is memory titanium alloy and bends a full 360 degrees without deforming, so it survives being shoved in a bag. Silicone enclosure, bone conduction drivers, 8 ohm impedance, button controls.
The rating is IP65. Read that carefully, because it's the single most important thing about this product: IP65 handles sweat, rain and splashes, and MASTJUST states outright that it is not suitable for swimming. If you buy this expecting pool use, you'll be disappointed — and that's on you, not them. I'd rather a brand be blunt about the limit than vague.
Where it fits: running, cycling, hiking, driving, working out. The open-ear hook design leaves your ear canal clear, which is the whole safety argument for bone conduction — you hear traffic, other runners, your surroundings, and your music at the same time. Bluetooth 5.0 gives a claimed 33-foot range, which is the widest here, and battery life is up to 8 hours with 480 hours of standby, charged over USB-C in about 2 hours.
One practical warning that comes straight from the maker: don't charge it with a fast-charging cable or adapter. It isn't built for that, and using one can stop it charging properly. Use a standard USB-C source. Beyond that, the trade-off is simply the rating — IP65 is weatherproof, not waterproof, and that's a hard ceiling. There's also no MP3 memory, so it's Bluetooth-only. For dry sports at a light weight, that's a fair deal.
This is the value-oriented sibling of the SilisoundTek — same basic concept, similar 30 g silicone build, IP68 protection, and a 32GB card for underwater playback. Model S800pro, made by Arington. If you want the waterproof-plus-MP3 formula without the brand-name premium, this is the one to look at.
It actually edges ahead on two specs. Battery life is listed at 10 hours versus 8 on the SilisoundTek, and Bluetooth is 5.4 rather than 6.0. Charging is faster on paper too — 1.5 hours to full. The driver setup is the same story: bone conduction drivers, 8 ohm impedance, 20Hz–20,000Hz. Package contents are essentially identical, with two charging cables, an adjusting belt, earplugs, a storage bag and a manual. Warranty is 2 years.
The right buyer here is a pool swimmer who wants the core features — IP68, 32GB of onboard music, decent battery — and doesn't care who made it. Note also that the controls include voice and Siri support and button control, which is useful once your hands are wet.

The ESS-911 is the most design-led option in this lineup, and that's clearly deliberate. A red-and-blue finish, a titanium core wrapped in liquid silicone, and a gift box rather than a plain carton. At 34 g it's the heaviest here, though the open-ear shape spreads that weight rather than pressing it into one spot. Bone conduction drivers, 8 ohm impedance, 85 dB sensitivity, 20Hz–20,000Hz.
On features it's genuinely loaded: Bluetooth 5.4, a 32GB MP3 mode you toggle with a double-press of the power button, AI voice control you trigger with a one-second hold in Bluetooth mode, and support for Google Assistant, Siri and volume control from the buttons. The 32GB memory plus the stated IP78 waterproofing means it's built with swimmers in mind — though I'd flag that IP78 is an unusual way to write that rating, and if swimming is your main use, the clearly-labelled IP68 sets above are the more straightforward bet. It works perfectly well for running and gym use either way.
The real trade-off is battery: 6 hours of average life, the shortest in this group, with a 2-hour charge time. If you train for 90 minutes a day, that's fine. If you're a marathon swimmer, it isn't. The other consideration is that with the styling and the box, part of what you're choosing is the object itself — which is a legitimate reason to buy something, as long as you know that's what you're doing.
I'd recommend this for someone who wants one pair that looks good on the street, handles a swim, and arrives presentable enough to give as a gift. Just accept the shorter runtime.
I compared the published specifications and feature lists of each set — waterproof rating, driver type, onboard storage, Bluetooth version, battery figures, weight, materials and included accessories — and weighed them against how people actually use bone conduction headphones: swimming, running, cycling and gym work. The order reflects my independent editorial judgement about which set best serves which buyer. No brand paid for placement or had any say in the ranking.
Yes, but not over Bluetooth — Bluetooth signals don't carry through water. The waterproof sets here solve it with a built-in memory card: you load songs beforehand, switch to MP3 mode, and the headphones play on their own. That's why the 32GB models are the ones suited to swimming.
The first digit is dust protection and the second is water. IP65 shrugs off sweat and splashes but is explicitly not for swimming. IP68 is rated for sustained immersion and is what you want for pool use. IP78 is a higher water figure on paper, though IP68 is the more commonly used and clearly defined rating for swimming headphones.
Yes. The drivers vibrate your temporal bone and leave your ear canal completely open, so ambient sound reaches you normally alongside your music. That's the main safety argument for using them on roads and trails. Some models also include earplugs for swimming, which you'd use only in the water.
For swimming, yes — several sets here include earplugs, and you'd wear them to keep water out while the bone conduction drivers bypass your eardrum entirely. For running and cycling, leave the earplugs out. Their whole advantage outdoors is that your ears stay open to what's around you.
