What is the best value for in ear headphones for the iphone? I had the Klipsch S4i last and they sounded great but they were not durable. About six months after I received them, the wire that attaches to one of the ear buds came apart. Since they were under warranty, I sent them back to Klipsch and get a replacement pair. The replacement pair also broke. I'm looking for something customized for the iphone with a great sound, that are not fragile and not too expensive. I'm looking to spend around $100. There is so much out there and I am curious as to what the regulars here have to say and which come highly recommended. Also, I'm curious to hear from those who had the Klipsch S4I and what their experience was. Thanks.
