Sometimes you just need to get away from the hustle, bustle and stress of the world for a little while. The latest generation of travel headphones helps to do just that with active noise cancellation that fades out the noisiness of airports, trains and fellow passengers. Now it is time for an upgrade. Manufactured by German audio specialist Sennheiser, the PXC 550 Wireless offers high-performance ANC and up to 30 hours of battery life, while delivering the high-quality sound that the company has become renowned for over the past seven decades. After its modest beginnings in a farmhouse in Wedemark near Hannover, Germany, in 1945, Sennheiser set out to become one of the world’s leading manufacturers of headphones, microphones and wireless transmission systems.
