sunvito Bone Conduction Swimming Headphones (Black) with IPX8 and built-in MP3 player
Product description
The essentials
If you do proper swim sessions, finding headphones that survive water (and don’t get in the way) is harder than it sounds. The sunvito bone conduction swimming headphones are built around that problem: IPX8 waterproofing, open-ear comfort, and two ways to listen depending on whether you’re on the pool deck or in the water.
What makes this model stand out on paper is the built-in MP3 player with 8 GB storage. Bluetooth is practical for land use, but under water signals generally don’t work the same way—so the MP3 mode is the whole point for uninterrupted training when you’re fully immersed or swimming freestyle.
Key points
You’re basically getting a swim-first audio setup: open-ear, bone conduction design that aims to keep you comfortable for longer sessions, plus a dedicated music path for the pool.
It also leans into everyday fitness beyond the pool. Because the ear area stays open, these headphones are designed to sit on your head without sealing your ear canal. That’s the sort of approach many people prefer for training—especially if you don’t want something wedged in or blocking your hearing completely.
That said, it’s worth tempering expectations: bone conduction can sound different to classic in-ear or over-ear listening, and the clarity you’ll get is fairly dependent on how well the headset sits on your head and the audio track itself.
What to know before buying
Bluetooth mode and MP3 mode solve two different needs. Bluetooth (with Bluetooth 5.4) is intended for typical use when you’re not relying on music underwater. For swimming, the MP3 player is the practical route.
There’s also a straightforward limitation to bear in mind: the Bluetooth range is stated up to 10 metres, and Bluetooth won’t transmit under water in the way you might be used to on land. So if your goal is fully submerged listening every session, you’ll want to make MP3 mode your default plan.
A small but important buying consideration is whether you’re comfortable managing music on-device rather than streaming from your phone. If you prefer to tap play from your mobile every time, this may feel like extra steps compared with fully phone-led options.
The essentials in use (pool training example)
Imagine you’re doing a structured swim set: warm-up lengths, then intervals. On the deck, you can pair in Bluetooth mode for convenience. But the moment you’re in the pool, you switch to the integrated MP3 player.
The idea is simple: your training soundtrack keeps going without needing your phone present near the water. For many people, that’s the difference between “music occasionally works” and “music reliably works for the whole session”.
Pros
- IPX8 waterproofing makes it appropriate for serious swimming and pool training.
- Bone conduction, open-ear style with a light weight (27 g) is designed for comfort during longer workouts.
- Built-in MP3 player with 8 GB storage (claimed up to 2,500 songs) helps avoid the phone-in-water problem.
- Bluetooth 5.4 is there for stable connection on land, with fast pairing and compatibility with iOS and Android.
- Battery claim: up to 10 hours after about 2 hours of charging, plus magnetic charging support.
What stands out (and where it may fall short)
Where it shines is the “swim logic” of having two modes. Lots of sports headphones exist, but not all of them handle the reality that Bluetooth and underwater don’t play nicely together.
The potential downside is that you’re buying into a specific listening method (bone conduction) and an on-device playback workflow for swimming. If your priority is the richest, most natural audio quality you can get—or you want purely phone-based streaming for every swim—this might feel more like a solid training tool than a full audiophile replacement.

Who it suits best
It makes sense if you want a practical set for swimming where music is meant to keep playing while you’re actually in the water. It also suits people who prefer open-ear listening during training, and those who are happy using a built-in MP3 library rather than relying on Bluetooth underwater.
It’s not the best match if you strongly need audiophile-grade sound, or if you really dislike the idea of loading/using music on the headphones for pool sessions.
Is it worth it?
Worth considering if you train in the pool often and want waterproof, open-ear bone conduction headphones that switch to a built-in MP3 player for underwater listening. The IPX8 rating and the presence of MP3 mode are the big reasons to look at this model seriously.
You may want to skip it if your main requirement is simple, phone-led Bluetooth streaming underwater, or if you already know you don’t get on with bone conduction audio.
For most swimmers who want reliable music during training, it’s a well-structured approach—just don’t expect it to behave like standard Bluetooth headphones used on land.
