These Bose QuietComfort 35 Wireless Bluetooth Noise Cancelling Headphones are quite frankly amazing. The sound quality, the wireless connection, but especially the noise cancelling quality. When you are wearing these and turn the noise cancelling on you are cocooned in your own little quiet world, away from any disturbances that surround you. They are especially great for flying, drowning out the aeroplane engine drone (along with any crying babies). They are a sound investment, even at £330. They come with a sexy carry case and recharging cable (up to 20hrs battery life) and can be used wired too. Just check out the reviews on these if you have any doubts about them.
