What is the difference between these 2x versions? Is it noticeable? I like the clear look more than the color versions so not sure if there is a big difference in them. For example these are what Im looking at: http://www.ebay.com.au/itm/Shure-SE...hash=item3d1dd41252:m:mubkCNNWrqBHzarC9NTHBNg http://www.ebay.com.au/itm/SHURE-So...597053&hash=item3f8226d895:g:1HwAAOSw-9RZbXOV But now you have the new white version, dont care for the volume control is that all it does no sound quality difference? http://www.ebay.com.au/itm/NEW-Head...779592?hash=item2a83bc42c8:g:VxQAAOSwurZZLZuF I remember reading back the SPE while costing extra did produce better bass but Im wondering after all these years have they manufactured the se215 differently are they even now and just a color difference?
