I am auditioning a pair of RHA 750's right now. I know these are not in the same league as the Cardas, but they are extremely comfortable. But coming from Monster Turbine Coppers, these just do not sound right. I am giving them another day to burn in to see if the sound changes anymore.
I really want to get a set of Cardas. But my unanswered question about the cable is holding me back. Anyone using these on the move? How about air travel?
I know I might be pushing it but has anyone tried these on a treadmill?
They are not comfortable on the move. You will have to figure out some method of controlling all of the extra heavy cable. Fusionramjet mentioned a lanyard and binder clip. Cable is microphonic. I have used them walking about, but it can get annoying. You will have to really like the sound of these to put up with them.
Air travel should be fine considering you will be stationary most of the time.
I would not use these on a treadmill. I'm not sure how you'd keep them in your ears.
These were really meant for stationary desktop use. Very impractical as a typical portable IEM.
