This was not disclosed and as such, entirely NEW drives and a NEW enclosure must be purchased to replace this unit which is ALREADY IN SERVICE. The shoes went very well with a black dress I brought for a very special occasion. When consumers order on line we expect colour descriptions to be reasonably accurate, most especially because electronic images can distort colours. I would have liked to pay less than 20 dollars for them but considering this was pretty much my only option, I guess its not the MOST amount of money they could have charged. It seems a good proportion of the £70 purchase price goes towards the truly gorgeous, Apple-quality packaging. Controller has a cheap feel to it. I have narrow, ?skinny feet? and the width is perfect for a lean foot. This product runs small order a size or two bigger than you would normally. I have a desk job and do some light walking and around the house stuff. The adjusting swivels of the ?cans? are very stiff, so the cans need to be manually pressed into your head every-time you wear them to achieve a decent seal and correct angle of the ear-cups; this is kind of ok, but clamping force also maintains the ?cans? in a solid stationary position while the drive unit oscillates back and forth.
