Maximum stability is provided by the ergonomic and lightweight design, which fits snuggly and gently in your ear. It is Wearable for extended periods of time while jogging, exercising, bicycling, trekking, etc. With a 1500mAh charging box, a Bluetooth headset can chat for up to 6 hours. With the help of the LED display, you can check the state of the power bank and the earphones’ charging. The charging case’s built-in USB connector can also be used to charge other USB devices. Please Take Note A typical cellphone battery has a 14,000mAh capacity. The power bank battery will quickly be depleted while using the 1500mAh charge box.

Bluetooth earphones are sweat- and water-resistant thanks to IPX7 waterproof certification, making them the ideal sports accessory. The silicone cover on the case’s charging ports keeps dust from gathering within the USB port and charge port. It allows for hands-free calling. Activate SIRI without picking up your phone to accept or reject calls. To change the volume, skip songs, and answer phone calls, gently tap on the earbud. Pick up the two headsets from the charging case, and they will be linked instantly in a single step. Then, to pair the device with your earbuds, just turn on Bluetooth on your phone.
