If you want a true bone-conduction headset that keeps its own internal music library and stays on your cheekbones through long pool sessions, choose AYI Professional Swim Headphones; if you need marathon battery life, a lighter titanium frame and a deeper bass engine for all-day training, choose mojawa Purra Swim IP68.
• AYI Professional Swim Headphones biggest strength: IP8 waterproofing with a patented sealed sound chamber, true bone conduction, 32GB of onboard music and Bluetooth 5.4 for land use.
• AYI Professional Swim Headphones biggest trade-off: 8 hours of playback per charge, a plastic build and a listed Bluetooth version that doesn't match the spec sheet.
• mojawa Purra Swim IP68 biggest strength: roughly 15 hours of battery life, a one-ounce titanium alloy frame and IP68 protection rated to 8.2 feet underwater.
• mojawa Purra Swim IP68 biggest trade-off: 32GB but a quoted 8000-song ceiling, and Bluetooth simply doesn't work while you're submerged.
• Pick AYI if you want a simple, sealed, bone-conduction swim headphone with a huge offline library and no app required.
• Pick mojawa Purra Swim IP68 if battery life, weight and deeper bass matter more to you than anything else.
The AYI CS05 is built around one idea: a sealed chamber that lets you keep listening while your head is under the water. The IP8 rating covers dust, sweat and full submersion, and the brand specifically calls out a patented full-seal sound chamber so the drivers survive long sessions in the pool. If you swim laps, do open-water sets, or just want music in the shower without babysitting a device, that design intent is exactly what you want.
The second half of the pitch is the dual-mode setup. You get Bluetooth 5.4 for wireless streaming on land, and you get a 32GB built-in memory bank that the brand says holds thousands of songs for offline playback. That's the part that matters in the water, because Bluetooth and water don't mix. Bone conduction drivers in the 20 Hz–20,000 Hz range push sound through your cheekbones, which keeps your ear canals open — useful for hearing a lane mate, a coach or traffic on a run.
Who should skip it? Anyone who trains for hours at a stretch. Playback tops out around 8 hours, which is fine for a normal workout but short for a full training day. The enclosure is plastic, so it won't feel as premium as a metal frame, and the control scheme is remote-based with no active noise cancellation. There's also a small spec inconsistency worth knowing about: the feature bullets say Bluetooth 5.4 while the product information lists Bluetooth version 5. Same family, but don't expect the sheet to be perfectly tidy. If you want a no-fuss, fully sealed bone-conduction headphone with a big offline library, the AYI is a sensible pick.
The mojawa Purra Swim IP68 reads like a headphone designed by someone who actually swims long distances. The headline number is battery: about 15 hours at 50% volume on a full charge, which is close to double what the AYI offers. For triathletes, masters swimmers or anyone stacking a swim, a run and a commute into one day, that gap is the whole story. You charge it once and stop thinking about it.
The frame is the other differentiator. It's titanium alloy and weighs roughly one ounce, and mojawa says it integrates with swim caps, goggles, sunglasses and bike helmets. That's a real-world detail — a light frame that plays nicely with a cap and goggles is much easier to live with than a bulky one. IP68 waterproofing is rated for depths up to 8.2 feet, so pool work and most recreational open-water swimming are covered.
Audio is where mojawa leans hardest. The Purra uses a 19mm dynamic driver with the brand's MaglevBass 7.0 magnetic levitation bass technology, an 8-ohm impedance and a 200-millisecond latency figure. In my reading of those specs, this is a bass-forward tuning aimed at people who want music to sound like music, not a thin trickle. You also get Bluetooth 5.3, app plus push-button control, active noise cancellation, a two-year warranty and a listed carrying case battery. The trade-offs: Bluetooth is land-only, so underwater you're limited to the 32GB library mojawa quotes at up to 8000 songs, and the ANC is a land feature that won't help you in the water.
• Best for battery life → mojawa Purra Swim IP68. About 15 hours versus roughly 8 hours on the AYI.
• Best for a lighter, sturdier frame → mojawa Purra Swim IP68. Titanium alloy at about one ounce, versus a plastic enclosure on the AYI.
• Best for deep, bass-heavy sound → mojawa Purra Swim IP68. A 19mm dynamic driver and the brand's MaglevBass tuning point that way.
• Best for a straightforward sealed swim headphone → AYI Professional Swim Headphones. IP8, a patented sealed chamber and true bone conduction, no app needed.
• Best for offline music capacity → close call. Both list 32GB; the AYI says thousands of songs, mojawa quotes up to 8000.
• Best for control flexibility → mojawa Purra Swim IP68. App plus push-button control and active noise cancellation for land use.
• Best for warranty coverage → mojawa Purra Swim IP68. A listed two-year warranty is a concrete long-term safety net.
• Best for land-only streaming simplicity → AYI Professional Swim Headphones. Bluetooth 5.4 for wireless use and MP3 mode when you're off-grid.
If I were buying for myself, I'd take the mojawa Purra Swim IP68. The 15-hour battery, one-ounce titanium frame and 19mm bass-forward driver are the three things I'd notice every single session, and the two-year warranty is a meaningful cushion on a device that lives in chlorinated water. The AYI is genuinely capable — IP8 sealing, true bone conduction and 32GB of offline music cover the basics well — but in my opinion its 8-hour ceiling and plastic build make it the better fit for casual swimmers than for people training seriously. Either way, check the current price on Amazon before you commit, since that's the one number that should decide a close call.
Yes. It carries an IP8 rating for water, dust and sweat resistance, and AYI describes a patented full-seal sound chamber designed to stay submerged for long periods. That covers lap swimming, open water and showering.
How long does the mojawa Purra Swim IP68 battery last?
About 15 hours at 50% volume on a full charge. That's roughly double the 8 hours listed for the AYI, which makes the Purra the stronger choice if you train for long stretches or go days between charges.
No. mojawa states plainly that Bluetooth does not work underwater and that you should use MP3 mode while swimming, and the same logic applies to the AYI. Both rely on their 32GB of built-in memory once you're in the water.
Based on the specs, the mojawa Purra Swim IP68. It uses a 19mm dynamic driver with MaglevBass 7.0 magnetic levitation bass technology, while the AYI uses a bone conduction driver. Bone conduction favors awareness and comfort over low-end punch, so if bass matters, the Purra is the pick.
