If you want a swimming headphone that doubles as a real-world Bluetooth headset for calls and runs on land, choose I love e iFecco IP68; if you need maximum offline music storage and a fit that plays nicely with a swim cap, choose KOPIDOE Swimming Headphones Underwater.
• I love e iFecco IP68 — biggest strength: a dual-mode design that switches between 8GB of built-in MP3 music and a Bluetooth 6.0 wireless connection, so it works underwater and on dry land.
• I love e iFecco IP68 — biggest trade-off: 8GB holds a few thousand songs, not tens of thousands, and Bluetooth simply doesn't work once you're submerged.
• KOPIDOE Swimming Headphones Underwater — biggest strength: a huge 32GB built-in memory card plus a fully adjustable headband that's designed to sit over a swim cap or hat.
• KOPIDOE Swimming Headphones Underwater — biggest trade-off: no advertised call handling, no stated battery hours, and it's a 4.8-ounce unit versus a 28g frame, so it's the heavier of the two.
• Pick I love e iFecco IP68 if you want one pair of bone conduction headphones for laps, runs, rides and phone calls.
• Pick KOPIDOE Swimming Headphones Underwater if you want the largest possible offline library and a headband you can dial in around a cap.
The I love e iFecco IP68 is the more versatile of the two on paper. It's an open-ear bone conduction headphone rated IP68, which the spec sheet says means it can handle depths up to 3 meters for 60+ minutes — enough for laps, surfing, kayaking or a hard rain run. Sound travels through the cheekbones rather than the ear canal, so your ears stay open and you keep your situational awareness on a road or trail.
What makes it stand out to me is the two-source audio setup. There's 8GB of onboard memory for roughly 2,000+ songs, which you load over a magnetic cable, and there's Bluetooth 6.0 for streaming from your phone with a stated 10-meter range. The catch — and it's stated plainly in the specs — is that Bluetooth doesn't work underwater, so you switch to MP3 mode before you dive in. On land, the same pair handles calls and wireless listening, which is a lot of utility from one device.
Battery is listed at 8 hours with a 2-hour charge time, and the frame is 28g of titanium with a flexible fit, an ABS enclosure and a solid black finish. In my opinion this is the pair to buy if you want bone conduction headphones that earn their keep seven days a week, not just on swim days. Skip it if your priority is squeezing an enormous music library onto the device — 8GB is generous for workouts but it isn't the biggest number here.
The KOPIDOE Swimming Headphones Underwater leans hard into the swim-specific brief. It's also an IP68, fully submersible bone conduction headphone with an open-ear fit, so the core pitch is the same: music through the cheekbones, ear canals left free, awareness intact. The difference is where it puts its emphasis.
Storage is the headline. KOPIDOE lists a 32GB built-in memory card holding over 80,000 songs — four times what the iFecco offers — which means you can genuinely leave your phone in the locker and never think about it. The company is upfront that you must switch to MP3 mode when swimming because Bluetooth won't work underwater, and it backs that up with Bluetooth 6.0 and dual-device pairing for when you're dry and want to stay connected to two sources at once.
The other real differentiator is fit. The headband is fully adjustable and specifically described as compatible with swim caps and hats, which matters if you're a cap-wearing pool swimmer or you train outdoors in cold weather. It's silicone-bodied, 4.8 ounces, and comes in purple with a magnetic charging cable, a spare pair of earbuds, an adjustment strap and a manual. Warranty is listed at one year versus two for the iFecco. Charging is magnetic and described as fast, though no battery-hour figure is given, so I'd treat runtime as the open question here. Choose this one if a huge offline library and cap-friendly fit are what you actually care about.
Side-by-Side: Which Should You Choose?
• Best for all-round use beyond the pool → I love e iFecco IP68, thanks to Bluetooth 6.0 plus a stated 10-meter range and clear-call support.
• Best for swim cap and hat wearers → KOPIDOE Swimming Headphones Underwater, whose headband is explicitly adjustable and cap-compatible.
• Best for a lighter frame → I love e iFecco IP68 at 28g with a titanium build, against 4.8 ounces for the KOPIDOE.
• Best for stated battery life → I love e iFecco IP68, which lists 8 hours of playtime and a 2-hour charge.
• Best for dual-device pairing → KOPIDOE Swimming Headphones Underwater, which supports two simultaneous Bluetooth connections.
• Best for a longer warranty → I love e iFecco IP68, listed at 2 years versus 1 year.
• Best for colour choice → KOPIDOE Swimming Headphones Underwater, offered in purple; the iFecco is solid black only.
I'd buy the I love e iFecco IP68. The reason is simple: it's the pair I'd still wear on a Tuesday run, a weekend ride or a phone call, not just in the water. The 8-hour battery, 28g titanium frame, Bluetooth 6.0 calling and 2-year warranty make it the better all-rounder, and 8GB is plenty of music for laps.
The KOPIDOE is the smarter pick only if your single priority is carrying a massive library and fitting over a swim cap — in which case its 32GB and adjustable headband are genuinely better suited to that job. Whichever way you lean, check the current price on Amazon before you commit, since both sit in the same budget accessory bracket.
are headphones waterproof
Not all of them — it depends on the rating. Both headphones here carry an IP68 rating, which means fully submersible, and the I love e iFecco IP68 is specified for depths up to 3 meters for 60+ minutes. A lower rating like IPX4 would only shrug off splashes and sweat, not swimming.
are headphones water resistant
Water resistant and waterproof are different claims. IP68 is the stronger of the two: it covers full submersion, which is why both of these are marketed specifically for swimming. Note that on both models Bluetooth does not transmit underwater, so you must switch to the built-in MP3 mode before you get in.
The KOPIDOE Swimming Headphones Underwater has a 32GB memory card and is listed as holding over 80,000 songs. The I love e iFecco IP68 has 8GB and is listed at 2,000+ songs. Both let you swim without carrying a phone.
The KOPIDOE Swimming Headphones Underwater is the one to pick here — its headband is fully adjustable and explicitly described as compatible with swim caps and hats. The I love e iFecco IP68 uses a flexible 28g titanium frame that's built to stay secure during flip turns, but cap compatibility isn't part of its listed spec.
