When your music is on, nothing else matters. The JBL Tune 770NC wireless headphones with adaptive noise-cancelling deliver on that promise all day long - and longer, too, while keeping you away from unwanted noise. With a battery life of up to 70 hours, you can easily get through a busy week with this one and still have enough JBL Pure Bass sound to get you through the weekend. And when you need a quick charge, you'll get an extra 3 hours of music in 5 minutes. Lightweight and foldable, the Tune 770NC can also connect to two Bluetooth® devices at once, so you never miss a call while watching a movie on your tablet. Download the free JBL Headphones app to customise the sound to your taste. And voice prompts in your language guide you through the features. Easily manage your calls and voice assistant right from your phone, and use VoiceAware to hear yourself when you speak. Just choose the colour that best suits your mood and let the fun begin.
