I have been taking this to the gym since Ive gotten it and it has been great. I normally had to leave my phone sittting on the machines or floor while I was working out and was always worried i may forget to pick it back up. This is very comfortable around my arm, don't feel hot or heavy and is really a great thing to have. My phone has a case on it and fits inside easily. I do wear wireless headphones so I don't personally have a wire to have to go through this but i don't see that being a issue. I could easily press the buttons through the plastic front and everything works great!
