Perfect sound, perfect price

Still "wearing these in" so early days. On the plus sound, good roomy sound, much better than my cheaper earlier pair of phones, with good sound exclusion. Also clearly well made and substantial: the down side of that, surprised how heavy they feel, makes extended wear a bit uncomfortable (though I may get used to it.) Still, very good value for the price.
