Well I thought it would be perfect. The first foot of the cable on my TripleFi 10 is too thick to wrap and the device to small for the cable. I'll try my older SuperFi 5Pro later and see if that works. Basically though I'd say it needs to be 50-100% larger or have a better way to retain the cord and ear plug. Bottom line if I were them I'd make these in 2-3 sizes. This one for cheap ear buds with skinny cords, and a larger one for audiophile grade in-ear-monitors.
