Say goodbye to tangled cables with these Sony wireless headphones. They connect to your device using Bluetooth, so you won't have to spend time working out what sort of knots they've put themselves in to start your playlists. And with an 11-hour battery, those tunes will still be going by the time you get home after a long day. Getting a call? The built-in mic makes sure you never miss a word. A simple swipe, tap or press is all you need to control them, and if your walking route takes you past a busy road, Ambient Sound Mode lets you hear noises like traffic to keep you safe.
