I've owned a DC 13.4 for 9 years, it flew with me for my first 4000hrs. 2 sets of replacement ear gels, one head-pad(wasn't necessary, but did it anyways).

I also have had a Clarity Aloft Pro for about 9 months. It's my X-C headset, works very well, Db's are greatly reduced. Does pinch a little bit if you put it on too tight, but constant wrenching on the wire frame has finally made it fit comfortable for over 3hr flights w/o any issues. I just wore it for 9+ hours yesterday flying a Meridian from Indiana to Portland, OR.
