Really digging the sound on the HTC One default headphones. Comparable to my CX300 II's. Bonus is the mic/remote. My only issue is I need some foamies. Thinking about making some of my own if I can't find any. Shame they don't give more options than the default rubbery seals.
 
Anyone else with these earphones?

What is the diameter of the nozzle? There should IEMs with similar size out there and foamies for them should in theory work on the HTC IEMs as well.

The speaker bit is about 5-6mm
