I've just returned my 3rd pair of broken V-Moda Vibe Duo (iphone) headphones to the apple store (regent street) and this time they said they would not give me another pair as they no longer display or stock that product due to the volume of returns. I take pretty good care of headphones and i've 'broken' 3 pairs, the build quality is appalling. They gave me a refund so i'm looking for similarly priced iphone headphones which MUST have the little call button on them. Has anyone tried these: http://store.apple.com/uk/product/TR530?mco=NzY2ODg0 (Sennheiser MM 50 iP) Or an alternative recommendation? Thanks.
