Summary: At first these 'phones will most probably disappoint and just like me will wonder why the hell you just spent £150 on them! Don't worry have patience, fiddle around with all of the ear buds to get a good fit and then squeeze them right into your lug hole to get an air tight seal.
Summary: These have taken a while to fully blossom. First impression was a bit meh compared to my previous B&W in ears, but over time I have either got used to them or they have broken in and I am very happy with them.
Summary: These have got to be the greatest in ear devices on the market. As a classical musician I find the uncoloured pure sound of these incomparable. Even plugged into an iPhone they really deliver and there is plenty of volume there.
Summary: Was looking for in-ear phones that would compare with the Bose noise cancelling over-ear format. Took a chance on the EB50s and I'm not disappointed. Obviously they don't reduce ambient noise down to levels Bose achieve (they're only passive, of course); but very impressive.
