Thanks a lot for your help, I will check this.

I'm still an happy user of these IEM but the cable is starting to wear out at the hinge between flexible and rigid portion of the cable (the part you wrap around your hear ), as shown in the picture: I'll try first to repair it ( I'm not a DIY guy) but I'm also looking for a cable replacement...

Update: I finally ordered Spinfit CP100 & CP145 after consulting Spinfit guys to check which model better fits in my IEM and can't be be happier. The sound and comfort improvements over the stock earplugs make them a must have, at least for the ATH-E50 and for me.

Thanks again, that's why I planned to experiment with double/triple flange. However I read some mild comments about double or triple flange ear tips apparently causing some possible sound degradation, slightly altering definition: did you notice the same?

Thanks for your reply, but which model would perfectly fit the ATH-E50, either single or double flange?
