The "wide" version basically allocates more real estate in the upper, making the leather upper able to expand further, thereby accommodating a wider foot. They are very light weight, so you can wear them for long periods of time (like at work) and not get the headache / earache that happens with most headphones. First one came with a scuff on the strap but amazon is always good with exchanges. I got a large due to my chest being a 34G currently. I received the earbuds in the U. This item does work fine, no need to program the tcu nor do anything else but to make sure you install it correctly, make sure you keep it free of debris or dust as much as you can. As a college professor, I need a respectable navy wedge that would match with my regalia but also march across a sometimes-muddy quad. You cant go wrong with this! Finally, the tripod is a sturdy accessory that I trust my iPhone on, which was ESSENTIAL in the decision making of this purchase. The next to last time I wore them the sole pulled away at the back heel of the shoe.
