These Active noise-cancellers are the type with a battery in a unit on the cable, allowing Audio Technica to make the headphone section small and light.
The on-ear design isn't quite as comfy as a full-on over-ear, but the 'ANC1s are surprisingly good at blocking out noise.
They also offer a balanced, detailed delivery that lends itself well to all music. However, next to the class-leading Goldring NS-1000s they do lack spaciousness and attack.
But if you're a frequent flyer whose priority is portability, these are well worth a look.
