I have a high arch on the top of my foot and struggle to get into many shoes, not one problem with these. Freunde von (E-)Gitarrenmusik, elektronischen Klängen und atmosphärischen Soundkulissen kommen voll auf ihre Kosten. I have a high instep and the velcro adjustable tab allows me all the adjustment i need. They are true to size and I think I want more pairs in other colors ?? Its not too fancy and can be worn on casual occasions as well. You need to basically remove the case from the silicone cover completely to open it, which happens easily because the fit is so loose. The microphone was ok - the 4 microphone array seems to do a pretty decent job of filtering out background noise from the testing I did. This little thing makes a nice sound! They worked great for a month, then the right earbud dropped in volume to about 25%. And if you havent done the math, thats$600 total for the Aiwas.
