I have been looking for the perfect wireless earphones for such a long time, since I've been using iPhone and as you know iPhone has only one socket for headset and charger. And who wants to stop the fun just to charge right. Good thing I found Sudio Niva earphones. DESIGN AND STYLE Sudio NIVA is equipped with a simple yet fashionable portable charging case/box, which doubles as a contemporary design that can go anywhere with you that provides an additional 4 charges. Overall, I love its cute design and style. CONFIGURATION SUDIO NIVA is so easy to set up and so easy to pair with any of your devices. You just have to: 1. Turn on the Bluetooth on your devices (eg smartphone, laptop) 2. Press and hold the button on each earphone at the same time until the red and blue lights are blinking (around 3 seconds) 3. Go to Bluetooth settings and select "SUDIO NIVA" and connect. AUDIO QUALITY With its remarkably compact construction
