On the basis of the review on the gadget show I decided to buy these even though I've never heard of this brand before. I'm glad I bought them as the price has gone up quite a lot since then.
They are comfortable and completely surround your ears. I use them with my smartphone and the sound is very good but the best thing about these has to be the noise cancelling.
If you are looking for headphones to take on a flight these have to be the ones to get. These are top end headphones with great build quality. They do fold up and come with a very smart case for travelling.
