I need some suggestions for headphones for my brother. I did a stupid thing and let him listen to my grado sr225's, now he wants some new headphones, but if it was humanly possible is even more skint than me . He currently has sony headphones mdr ... whatever (see the problem) and likes a little more bass response than neutral. Looking to spend a maximum of £30-£40 ($60-$80) .Grado's are out of the question cant even get a pair of sr60's for less than £60 or $120 on ebay, im looking at sennheiser, akg and beyerdynamic for him. What headphones offer the best bang for the buck at that price range?
