I'm interested in getting a new set of headphones for my iPhone. I'm pretty picky with sound quality and such so I'm interested in getting the best I can find. I heard that a lot of people like the sound or the V-Moda Vibe Duo Nero but that there seems to be a workmanship quality problem - a lot of people have had to send them back under warrantee. The Ultimate Ears Super.fi 4vi was another that people have mentioned, but I kinda wondered abotu the specs of it. The frequency range doesn't seem that wide. I was also thinking about the Bose In Ear headphones and using a BlueTooth headset for calls. Was even considering buying that Blue-Tooth adapter for wireless music while I was at the gym. Anyways, any thoughts and opinions? Anyone have any of these headsets?
