If you have a good pair of headphones, this should sound the most natural. I added a pic for you all. I figured one of them had to be useful. And my daughter could wear them and she wear a size 7. As for sweat, its leather. Seems to do the job. The charging port is under a cap and well hidden from any moisture, so Im confident sweating at the gym or running in the rain wont bother it. Given poor quality control, we returned the product Easy to install. This is holding up great so far!
