Now that my cold and congestion have mostly cleared up, I must say that I still find that pressure builds to somewhat uncomfortable levels in one ear after using the EarThumps for a short amount of time (more-so when music is playing than not). Also, I hear a low rumble, which is either due to the building's HVAC system or the natual sound I get when I put my fingers in my ear and form a seal (sound of blood flowing maybe?). Finally, I feel some ear fatigue after less usage than with the iPod's regular earbuds, probably because I cannot turn the volume down any lower--yet it's near the mid-point of my comfort range.
Anyone else finding things like this? Or am I just being way too picky / perceptive?
