Good but Not Very Durable

The sound quality is excellent and, with the three different pair of ear fittings, should fit most ear canals.  My ear canals are very small so I used the smallest fittings.

The bass sound and clarity throughout the audio spectrum is very good.

However, the buds get dirty easily (ear detritus) and required frequent (hourly?) cleaning.  They stopped working completely after several months.  They were never dropped or abused in anyway.  Next time I will keep the paperwork for warranty purposes.

I'm torn between ordering another pair (they aren't very expensive) and sticking with my Koss earphones that I bought to replace them.
