Query: Earclip Issues

I ended up returning the headphones in less than a month because the earclips regularly came off. While it is possible to pop the earclips back on, it's frustrating to be stopping every five minutes during a run to make the adjustment. I also found the headphones to be an uncomfortable fit -- perhaps I have unusually shaped ears. The sound quality was great.
