Conclusion: £200 is a lot to spend on headphones, but these come with decent accessories, sound terrific and have customisation potential most headphones can only dream of. In short, we like them, a great deal.
Summary: We were rather fond of the old Sennheiser IE 8 in-ears . Massively comfortable, well made and deeply, adjustably bassy, they were great for fluid tunes on a long commute. But it's possible they were just a touch too smooth, which could take some of the kick out of pumping tracks.
