If anybody is intersted in a proper opinion/review of these new cans, I would wait until a reviewer who actually has a clue (such as headroom, the headfi forums, etc.) put these to a subjective test against the close competition. All of the reviews & opinions linked so far in this thread come from people who don't honestly know much about headphones & can't justify their opinions more than
"they sound great!" or have only compared them to things like the stock Apple headphones & not to the real competition.
There's a
thread going on headfi about these particular cans which will probably be the first place that a genuine subjective review from an expert in the field will be posted or linked.
Of course, Apple are still going to make an absolute mint on this product, in the same way that Bose do on the vast majority of their products; creating speakers & headphones based around cheap OEM components (in the case of these headphones it's the TWFK-30017-000 dual armature speaker from Knowles Acoustics, which Apple probably buy in for less than $20 a piece) then relying on the naivety of the general public to believe all the marketing & hype they place on the product to buy it & truly believe that they are listening to an amazing sounding set of headphones, when in actual fact they could probably get a much better sounding pair at the same price-point (or less) by shopping around a bit & listening to subjective opinions rather than the producer's marketting department.
