What these earbuds are

These are new in-ear wireless earbuds that use Bluetooth 5.3 and a USB-C charging case. A single charge gives up to 8 hours of listening and the case extends total play time to 46 hours. Touch controls handle playback and calls without reaching for the phone.

Who they suit and who they don't

They suit listeners who want long battery life, a clear LED power display and IPX7 resistance for sweat or rain. Buyers who need active noise cancellation, multi-point pairing or a wired connection option should look at something else.

The spec that decides fit

Bluetooth 5.3 is the single specification that determines compatibility; the earbuds pair automatically after the first connection and maintain a stable link up to 10 meters.

Questions about this item

Does Bluetooth 5.3 limit the connection distance in practice?

The earbuds maintain a stable link up to 10 metres, which is the practical range for Bluetooth 5.3 in open space.

What comes in the box to ensure the earbuds fit securely?

The package includes silicone ear cushions in multiple sizes so you can choose the best seal for your ears.

How do I pair the earbuds the first time, and what step do users often miss?

Open the charging case, select the earbuds from your phone’s Bluetooth list, then close the case; future connections happen automatically when you reopen it.
