QuietComfort SE headphones are the reinvention of a classic. The original is back - noise cancelling headphones, now with a unique combination of premium noise reduction, supreme comfort and exclusive acoustic technology for powerful, crystal clear sound with customisable equaliser that lets you tune your music to your liking. Optimised Acoustic Noise Cancelling technology ensures true silence, so you enjoy every detail of your music with lifelike, top-of-the-line sound. The new Aware mode lets you listen to your music and your surroundings at the same time. TriPort sound architecture and volume-optimised Active EQ technology, a Bose innovation, deliver deep, clear sound that's balanced at any volume. Carefully selected lightweight materials such as faux leather and fibreglass-reinforced nylon make the headphones exceptionally durable and comfortable to wear. They provide 24 hours of playback*, charge via USB-C and feature four beamforming microphones for clear phone calls. Bluetooth 5.1 ensures a stable connection. The Bose Music App guides you through setup, lets you personalise your settings and keeps the headphones' software up to date. * Battery test conducted by Bose with active noise reduction turned on and audio playing continuously at 50% volume.
