PITTM,
Have you seen Klipsch's new earphone line? I'm thinking about getting the Klipsch NOISE model

Is it reasonable to have headphones for:
1) Earphones (thinking Klipsch NOISE) -- working out, walking around
2) Good headphones (Sennheiser HD650) -- computer/in home listening
3) Noise canceling headphones (have Bose QC2, thinking Senn PXC450) -- travel
