These Bowers & Wilkins PI5 In-Ear True Wireless Headphones (£200) are by far one of the best pairs I've ever tried. With advanced noise-cancelling, and four microphones for enhanced clarity, they pair with an app on your phone that can adjust volume, turn features on and off, and let you know when they need charging.
Available in two clean colourways, they boast a wear sensor, voice activated calling, and smart charging case for fast wireless charging. It doesn't get better.
