Wireless earbuds with 72-hour case

KT1 A12 wireless earbuds use Bluetooth 5.3 and come with a charging case that provides up to 72 hours of total playtime. The gold-finished buds feature an over-ear hook design for a secure fit during sport and running. A built-in digital display shows remaining case power at a glance.

Check Bluetooth version and fit preference

Your phone, tablet or laptop must support Bluetooth 5.3 for full compatibility. The earbuds use touch controls for media playback and calls, so ensure you are comfortable with tap gestures. The package includes only the protective charging case; no extra cables or ear-tip sizes are supplied.

IPX7 waterproof rating handles sweat and rain

The IPX7 rating means the buds survive immersion in shallow water, making them suitable for intense workouts and outdoor runs. The 10 mm graphene dynamic drivers deliver enhanced bass without a bulky housing that traps heat. Each bud weighs very little, so extended sessions stay comfortable.

Questions about this item

What comes inside the package and what must I purchase separately?

The box contains the wireless earbuds, a charging case with LED digital display, and earhook wings. No charging cable or power adapter is included, so you will need a USB-C cable and a 5 V charger you already own.

How do I decide between the available versions or capacities for the A12?

Only one version is offered: gold colour, Bluetooth 5.3, 10 mm graphene dynamic drivers, and a case rated for 72 hours total playtime. There are no alternative capacities or feature tiers to choose from.

What does the 72-hour playtime figure mean when I use the earbuds daily?

Each charge gives about 8 hours of listening; the case holds enough extra power for roughly eight full recharges, reaching the 72-hour total. Real-world time varies with volume level, codec, and whether you use mono or stereo mode.
