I'm considering replacing my Shure E3c headphones with either Senn HD580 or Grado SR80. Both are open air headphones. My intent is for these to be used both at home and on the commute to work (bus and train). I love my Shures, but the earplugs keep popping off the earphone... especially when I work out, sweat tends to keep those little buds IN MY EAR, so that when I remove the phones, the buds fall onto the ground. This is REALLY irritating, I've tried everything else in my fit kit, and nothing seems to fit my ear and isolate out sounds as well as these. My concern is with going out in public, will the open air earphones be heard by everyone else around me? How loud is it? I don't listen to my music loud. I just don't want ot be self conscious of it all the time. I would like to try them out, but don't know of anywhere in Calgary that carries them. Suggestions? tx.
