With the Birst Apollo Bluetooth Headphones, you can listen to your playlists wherever and whenever you want. The Active Noise Cancelling technology allows you to focus on what you're listening to without being distracted. Bluetooth 5.1 connects to your phone from up to 10 metres away and still delivers clear, glitch-free audio. They come with a built-in microphone and allow you to answer calls hands-free. They also come in a hardshell case that protects them when not in use.
