8Hz to 100kHz frequency response and vacuum tubes that rise out of Carrara marble.
The Dottir Freedom On-Grid buds and the Sennheiser Sport True Wireless are both pretty decent buds. The former offer excellent water resistance, great bass and impressive noise cancellation. The latter provides comfort, quite dominating bass and intuitive controls.
The Sennheiser EPOS GSX 300 manages to be both a solid external sound card and an intuitive profile swapping device, that is both sleek and satisfying.
The GSP 601 thoroughly impressed with its audio realism and striking design but I had to deduct half a point for the exceptionally tight volume wheel.
Waiting for the inevitable Chinese knock offs to hit the market =p
these headphones better give a continual orgasmic experience.
At least the sound quality is of an apparently very high quality, it would suck if after all that it was average.
You'd have to have lost your marbles to pay that much for a pair of headphones. I'm pretty sure it's made of marble, so as to have it's owner feel as if they hadn't lost them first place.
Sennheiser as a brand really does make a lot of remarkable/progressive headphones, but believe this will only be snapped up for being a collectors' piece.
