You lost me scuttle, I'm just trying to learn how to take the information given by reviews of gear on this site to make my own purchase decisions.  

So is we go from the understanding that "electronic devices are usually very flat" then how come most reviewers on this site speak of certain head gear being lacking or robust in highs, mids, lows? Or is this a different issue entirely from being airy/warm/cold?

Hey guys, I jumped into higher than average audio equipment when I purchased a pair of Ultrasone HFI-700 headphones after reading reviews on this site about 4.5 years ago. I also own a pair of Shure IEMs but I don't know what the model is. They are 5+ years old, have a large phone/music switch...
