The Dual Driver BT ANC In-Ear Headphones are interesting looking headphones, with a solid but light weight neck band and the earbuds, attached by a wire set higher up the band, not at the ends meaning it fits all shapes and sizes without the risk of neck band tugging on the earbuds. The Active Noise Cancellation (ANC) aims to provide you clear sound in any environment allowing you to chill out during the noisy commute or drown out the daily chatter in the office with your favourite audio book.
