A shame as Ive been wearing Teva for some 20 years. Using the turtle beach app also works very well have no complaints Not much cotton at the tip. Thought I would try IEMs. No rubbing on the bunions on my pinky toe side. I love that, and it has been so useful when studying and writing papers for college finals. Also Its Awesome on GLASS ! Has not taken them off since receiving them. Most comfortable sandal ever. For those not familiar with these type of sandals they may be uncomfortable to start with but after being worn for a period of time and exposed to the heat from your feet they mold/adapt to the wearer feet; This makes them uniquely comfortable.
