It's fair to say that by now most people who have an interest in wireless headphones know that the top 3 headphones for noise cancelling are Bose, Sony and Sennheiser.
Excellent wireless sound quality and signal; Touch controls; Excellent battery life; Good passive noise cancellation; Goes nice and loud; Pairs fast to your phone
Expensive; Not as comfortable as Sennheiser 598 for example; Potentially fragile (previous model suffered with cracking headband so far so good with this model though)
