UMIDIGI J18 Bluetooth 5.0 TWS Earphones Black

SKU CH-R9ZJ-836MZ

Bluetooth 5.0 true wireless earphones with a charging case providing up to 10 recharges and four hours of binaural talk time

  • ColorBlack
  • Bluetooth 5.0 for stable wireless audio
  • 220 mA charging case delivers 120 hours standby
  • 1200 hours total standby keeps earphones ready
  • 4 hours binaural talk time per charge
  • 10 full recharges from the compact case

Product identity and target user

The UMIDIGI J18 is a pair of true wireless earphones finished in black that connect through Bluetooth 5.0. They are built for listeners who want a compact, cable-free option for calls and music while on the move.

Upgrade path and when it matters

These earphones replace older wired sets or earlier wireless models that lack Bluetooth 5.0 stability. The jump is worthwhile when you need up to 120 hours of long standby, 1200 hours of total standby, or four hours of continuous binaural talk without reaching for a cable.

Installation ease and common pitfalls

Pairing is a standard Bluetooth 5.0 handshake with a phone or tablet. Each earbud can be charged from the case about ten times, so forgetting to top up the case is the main reason the buds run flat before the day ends.
