May be off topic but I myself bought the ultimate ears superfi 5 pro about a year ago and I must say they sound nice and I'm happy that I bought them.

But, I would not tell anyone to buy them. Why?

1)The cord broke after 10 months
2)logitech bought them out so the customer service is garbage.
3)Trying to find a replament cord make take time since it seems they are not making them or making only 1/4th that they use too.

Other then that I like them.
