If you're tired of your workout music cutting off when it gets wet or struggling to find a reliable pair of earbuds for swimming, the BZOJIFO S25 Waterproof Earbuds might just be the solution. These earbuds are specifically designed for swimmers and fitness enthusiasts, combining IPX8 waterproofing, built-in MP3 playback, and secure, comfortable wear. In this review, we break down the features, performance, pros and cons, and help you decide whether the S25 is worth diving into.
Unlike standard wireless earbuds, the BZOJIFO S25 are engineered with a swimmer’s needs in mind. From underwater audio playback to sweatproof durability, here’s a closer look at what makes these earbuds unique.
The standout feature of the S25 earbuds is their IPX8 waterproof certification, which allows full submersion in water up to 20 feet deep. Whether you're swimming laps, taking a shower, or caught in a downpour, these earbuds can handle it. This rating ensures they’re safe for all aquatic activities, not just splash-resistant like most earbuds.
Because Bluetooth doesn't work underwater, the S25 offers a dedicated MP3 mode with 32GB of internal storage, letting you store up to 1,800 songs directly on the earbuds. Just press the “+” and “–” buttons simultaneously to switch between Bluetooth and MP3 mode, making it easy to transition between workouts and water activities.
Powered by 11mm dynamic speaker drivers, the S25 delivers impressive Hi-Fi stereo sound with punchy bass, clear mids, and crisp highs. Thanks to its in-ear structure and acoustic chamber design, the earbuds maintain sound quality by balancing internal and external air pressure—ideal for both music and phone calls in noisy or wet environments.
The flexible ear hooks are specially designed to stay put even during intense activity, including strenuous swimming strokes. The earbuds are lightweight and can be worn with swim caps, goggles, and earplugs. The snug in-ear design also helps prevent water from entering the ears and muffling the sound.
The BZOJIFO S25 is equipped with a 180mAh lithium battery, offering up to 16 hours of continuous playback and a 150-hour standby time. With just 1.5 hours of charging, you're ready for a full week of daily swimming or long workout sessions without worrying about running out of power.
These earbuds support two modes:
This versatility makes them ideal not only for swimming but also for running, cycling, gym workouts, and even daily commuting.
The BZOJIFO S25 Waterproof Earbuds are priced at $51.99 in the United States, offering a budget-friendly alternative to many premium waterproof or sport earbuds on the market. Given the inclusion of 32GB storage, true IPX8 waterproofing, and solid audio performance, the price reflects excellent value for money.
