I love and have always loved Klipsch speakers. With that said, I wanted a pair of ear-buds/earphones for my ipod, but as you know price is what has keep me from getting a pair, that is until now. I picked up a set of Custom 1's, for a great deal online because Klipsch is no longer going to have the Customs. My father picked up a pair of the new S4's, and I thought that they were great. I seen that Klipsch had the Customs, and feel in love with the design, I do a lot of working out and walking, so over the ear looked like the way to go. I got my set a couple of days ago and I have to say, I do love the fit, and the design, but.... I'm not as happy as I thought that I would be with the sound. Kind of disappointed really! I should have done more research and read more reviews than what I did. Looks like I would have loved the Custom 3's. I found the the Custom 1's lack bass. The mid range is fantastic, but where is the bass? ugh! These are not the phones for me. But I have to say again that I do love the fit and the design, they don't fall out while I'm running. Not sure if I'm going to keep them and give them as a gift to someone, or try and return them.
