The pads of my Quietconfort unleashed 15 (opening and revealing the foam). This product is an exact replica of the original part. A Quick Guide will remove and replace error-free pads without breaking, quite intuitive operation that is done quickly and without difficulty. We find exactly the original sensations. A black spot in the table, a little crazy prices admittedly practiced by Bose ... but when you take this type of brand, we know from the outset what to expect ... which does not prevent me to recall and withdraw a star.
