Block out the noisy train carriage and settle into your playlist with these Sony WH-CH730N noise cancelling headphones. Dual Noise Sensor technology picks up the sounds around you and cancels them out, so you can focus on your music. When you need to hear an announcement or chat to a colleague, Ambient Sound mode lets outside noise in at the push of a button. Streamed tracks sound close to the original recording too, because DSEE restores detail lost when files are compressed. You can fine-tune the sound to your taste with the 10-band equaliser in the Sony | Sound Connect app. With up to 75 hours of battery life when noise cancelling is off, you'll get through a week of commutes without reaching for a charger, and the folding design packs away neatly in your bag.
