Mecha-styled wireless earbuds with spinner case

Fantech YZ2103 earbuds combine Bluetooth 5.3 connectivity with a zinc-alloy charging case that doubles as a finger spinner. The case uses dual silent bearings for smooth rotation and includes RGB LEDs that pulse in blue and red tones. A detachable alloy frame allows clip-on customisation for bags or clothing.

Gamers and commuters wanting low latency

The 65 ms latency mode suits competitive mobile gaming, while HD ENC call reduction keeps voice clear on the move. Buyers who need active noise cancellation for flights or multi-point pairing for simultaneous laptop and phone use should consider other models.

5-hour buds with four extra charges from the case

Each earbud weighs 4 g and runs for 5 hours at 70 % volume. The 220 mAh case recharges the buds four times via Type-C in about three hours. Total packaged weight is 230 g with a 16.3 cm by 9.5 cm by 4.4 cm box.

Questions about this item

How much power does the Type-C charging case draw while the earbuds recharge overnight?

The case charges from a 5 V 500 mA source and its 220 mAh cell fully refills in about three hours, so sustained draw is modest.

What device and connector must I already have to power the charging case?

Any USB host with a Type-C port supplying 5 V at 500 mA will charge the case.

Will the 65 ms low-latency mode work properly with my older Bluetooth 5.3 phone?

Bluetooth 5.3 is backward compatible, so the earbuds pair with earlier Bluetooth versions while retaining ENC noise cancellation and LED effects.
