The only time I have had any issues with the heel strap slipping (as some reviewers have noted) is when my heels are really dry, but thats an easy fix. The earbuds have full stereo for voice calls, meaning that you get sound in both earbuds. These crocs are slightly shorter than my previous standard croc style. The Bluetooth is easy to pair and Simple to operate without anything protruding into my ear. The addition of the garden scissors was nice too. Runs narrow! Almost looks stock with the color used. I bought this pair after long and thorough comparison with competing brands in the same price range. Short version: These headphones are great at this pricepoint. THE SOUND REPRODUCTION JUST ABSOLUTELY SHREDS ANY THING I HAVE EVER LISTENED TO IN MY LIFE.
