JHM Trading Co.,Ltd F9-8 bluetooth headset BT 5.0 2000mAh case CVC 8.0

Wireless sports earbuds with powerbank case

The F9-8 earbuds connect wirelessly and deliver 8D HiFi sound with CVC 8.0 noise reduction. A smart LED digital display shows the case charge level while bright button lights add visibility. The compact buds sit securely in the ear canal for stable workouts. The 2000mAh charging case doubles as a portable powerbank for other devices.

Single or dual ear use for calls and voice control

Each bud works alone or as a pair, letting you keep one ear free for traffic or conversation. Multi-button controls handle track changes and summon the voice assistant on a paired phone. A built-in microphone supports hands-free calls while driving or exercising. Buyers who need active noise cancellation or extended single-charge playtime beyond six hours should look at other models.

2000mAh case capacity determines total runtime

The charging case stores 2000mAh and each earbud holds 50mAh for roughly four to six hours of use per charge. Replenishing the case takes about two hours. This capacity dictates how many full recharges you get away from a wall outlet. If your daily listening exceeds the combined runtime the case can supply, a higher-capacity case will be necessary.
