I am disappointed after a recent MR with my newly purchased E2c ear buds. I just purchased them from Amazon and used them around the house for a few days before heading out on a MR to FRA. I was excited about taking it as my experience at home had been very positive. I settled in on the red eye from SEA to DFW put them in and found the noise blocking to be fine and the music very clear. However as we began to descend my right ear began to throb. This became very noticeable and I had to start rubbing the side of my head. I had taken the ear buds out by then (my left ear was fine though) and the pain continued a bit even after we landed. After a short stay in DFW it was back on to FRA. My ear was fine by then so I just figured it was one of those things. But the same thing happened on the way into FRA, again right ear only. I decided to use a different headset on the way back and had no problem.

So now I am a bit scared to use the Shure set on flights, the primary reason I bought them, even though I think they did great at home. I have another trip in a couple of weeks (within the 30 day refund window) should I try them again or just send them back before I do any damage to my ear? Has anybody else experienced something like this?
