UMIDIGI Fineblue J1 Pro TWS Earphones

The UMIDIGI Fineblue J1 Pro are true wireless stereo earphones finished in black. They use Bluetooth 5.0 for a stable link up to 10m. The set is designed for listeners who want cable-free audio with automatic pairing and a compact charging case.

14 mm drivers with NdFeB magnets

Each earpiece houses a 14x2.0 mm full-range driver inside a 3D stereo cavity. A high-strength NdFeB magnet drives the diaphragm for a wide soundstage and heavy bass. This driver size is the core specification that defines the audio character.

Up to 3.5 hours talk time per charge

A 30 mAh lithium polymer cell in each bud delivers about 3 hours of listening or 3.5 hours of talk time. The 52x45x27 mm case provides three to four extra full charges and refills in roughly 1.5 hours. Standby reaches about 60 hours.

Questions about this item

What does the 10 metre Bluetooth 5.0 range mean in daily use?

The supplier rates the effective distance at within 10 metres; walls, body shielding or other radio sources can reduce the practical range below that figure.

What does Bluetooth 5.0 cap in practice for these earphones?

Bluetooth 5.0 handles the wireless link and the 10 metre rated range; audio quality and latency depend on the source device and codec support.

What do the 17x40x19 mm earbud and 52x45x27 mm case dimensions mean for fit?

Each earbud measures 17x40x19 mm and the case 52x45x27 mm, so they sit shallow in the ear and the case fits small pockets or a keyring.
