Hi guys. I am in need of a good IEM on a $50 - 100 budget. I mainly listen to Progressive Rock/Metal (Rush, Opeth), Jazz (Winton Marsalis, Miles Davis) and Classical. I am currently using JVC Marshmellows for IEM's. Output is only from a 4th gen iPhone (no amp). Here's the catch, I am currently in Japan. I would rather avoid ordering online (I am leaving for an extended trip in the next 2 weeks and don't have time to wait for them to arrive). Brands I've seen at the local stores include JVC, Altec/Lansing, AudioTechnica, Pioneer, and Sony. Might have seen Klipsch, not sure. Any suggestions would be greatly appreciated!
