Recently I considered getting a good pair of in-ears for portable use. I don't have easy access to in-person auditions, but I was able to listen to a pair of Grado GR10s. I thought they were so bad I couldn't understand why anyone would ever listen to them. I thought I must be doing something wrong; however, a sales person thought things were correct. But a pair of SR80is trounced the 3-times-as-expensive GR10s. At home I have a pair of HiFiMan HE-500s; they sound wonderful. Every time I use them I feel that their purchase price was money well spent. Do people describing the sound of in-ears adopt a completely different standard than the one they use to judge everything else? Any ideas about what is going on here. TIA for any insights.
