- Built-in MP3 storage offers a listening option that does not depend on Bluetooth during swimming.
- The open-ear design leaves the ear canal uncovered.

What to know before buying
Listing details to confirm
The manufacturer claims IP68 protection and use at 3 metres, but these are listing claims rather than independently verified measurements. Bluetooth may be affected while swimming, so use MP3 mode underwater. The stated 6-8-hour playback time is a general listing claim without a specified operating mode. The listing calls the design both True Wireless and bone conduction with a rear-hook fit, so confirm the physical style and fit details if they are important.
Who is it for?
A good fit for
- Swimmers who want onboard music playback without relying on an underwater Bluetooth connection.
- Outdoor exercisers who prefer an open-ear design and physical buttons.
- Buyers seeking wireless earphones with built-in MP3 storage.
Less suited to
- Listeners who need Bluetooth streaming to work reliably underwater.
- Buyers who require noise cancellation or isolation.

Aggregate ratings are mostly five-star, with a smaller spread across lower ratings. This suggests generally favourable overall scores alongside some less favourable experiences, but ratings alone do not identify what customers liked or disliked. The scores do not verify the claimed waterproofing, battery life or underwater Bluetooth performance.
