Ideal for Plane/Rail travellers, or if you just need a bit of peace and quiet.  These active noise cancelling headphones work to reduce all outside noise e.g Aeroplane noise, allowing you to enjoy your music without other sounds leaking in. 

Alternatively you can use them purely as active noise cancelling headphones without music playing.

GET THE MOST FROM YOUR MUSIC.....   The earphones you receive bundled with ipods and mp3 players are notoriously poor, meaning you don't get the full audio experience from your sounds. 
Hear everything and listen to your music the way it was meant to be heard with a set of Sennheiser Earphones!!
