I bought a couple of pairs of Lightspeed Zulus earlier in the year and they are well worth the money. I tried the Bose' - they were very good too but what swayed me was a review in L**P which put them at No 1 and the metal headband. I thought the hinge was intrustive & could scratch the inside of a canopy.
Mrs K likes them too as she can plug her iPod in & listen to that.
But I think there is so little to between them that it comes down to personal choice.
