MTYBBYH S25 IP68 Waterproof Earbuds with 32GB MP3

MTYBBYH S25 are swim-ready wireless earbuds that combine IP68 submersible waterproofing with a built-in 32GB MP3 player and Bluetooth 5.2 for versatile use in water and on land.

Designed for swimmers, gym-goers, and outdoor athletes, the S25 earbuds let you listen to stored music offline or stream wirelessly when you're on dry land. The package includes dual-layer ear tips for a watertight seal while swimming, single-layer tips for day-to-day comfort, and an ergonomic low-profile form that fits under goggles, caps, and helmets. Fast charging yields long playtime so you can focus on training without constant recharges.

How do these earbuds handle being underwater?

The S25 carries an IP68 rating, which means it is engineered to withstand full submersion up to roughly 8 meters (26 feet). Special pressure-resistant design keeps volume and clarity stable even at depth, eliminating the common issues of muffled or fluctuating sound in the pool.

• IP68 certified for submersion up to 8 meters (26 feet)
• Pressure-resistant housing to prevent audio distortion
• Dual-layer swim ear tips for a secure waterproof seal
• Note: Bluetooth is disabled underwater—use the onboard MP3 mode while submerged

Can I use these earbuds for running and gym workouts?

Yes—the S25 is built to be a multi-sport audio solution. The lightweight ergonomic shape and included single-layer ear tips deliver a comfortable, stable fit for running, cycling, weightlifting, and other land-based activities.

• Slim, secure fit stays in place during vigorous movement
• Sweat- and water-resistant design for intense gym sessions
• Compatible with helmets, goggles, and sunglasses
• Up to 12 hours Bluetooth playback or 10 hours using MP3 mode

What audio quality and storage features do these earbuds offer?

S25 earbuds include 12mm high-precision drivers tuned for deep bass, clear mids, and crisp highs, delivering richer sound than typical bone-conduction swim options. The earbuds also include 32GB internal storage—enough for roughly 3,000 songs—so you can leave your phone behind during swims or workouts.

• 12mm drivers for enhanced bass and clarity
• 32GB onboard memory for offline listening (≈3,000 songs)
• Dual play modes: Bluetooth 5.2 for wireless streaming; MP3 mode for offline playback
• Quick 1.5–2 hour charge for extended battery life

How do I choose the right ear tips and maintain a good fit?

The S25 ships with both dual-layer swim tips and single-layer everyday tips so you can switch depending on activity. For underwater use, fit the dual-layer tips to create a reliable waterproof seal; for running or gym sessions choose the single-layer tips for breathability and comfort.

• Use dual-layer tips for full waterproofing during swims
• Use single-layer tips for land-based comfort and ventilation
• Check fit before activity; adjust gently to ensure a secure seal
• Rinse and dry after saltwater or chlorinated water exposure to extend product life

Who is this for? The MTYBBYH S25 is ideal for swimmers who want an authentic listening experience underwater, triathletes and open-water athletes who need submersible gear, and fitness enthusiasts who want a single pair of earbuds that works reliably both in and out of the water. If you value strong waterproofing, onboard music storage, and a stable fit that pairs with helmets and goggles, the S25 delivers a practical, high-performance option.
