These are a lot more comfortable than standard ear buds but my ear still gets a little tired after a long trip with them (3-4 hours). They seem to be made well; I have knocked them around a little in the month I had them and they are still working well. They didn't work well when I tried running while using them; they pick up the bumps from my feet (this is probably the case with all ear buds).I noticed the bass does get better after a few days but I mainly listen to talk so I have no sound complaints.
