My only complaint is they do make his feet hot. I did not like the cheap thin carabeaner that came this this so I bought a sturdy one and it works great. The sound is great but the wire is short they fit your ears nice and tight but if you move your head left or right they pop out. Ajusta excelente. Too bad they dont do half sizes. I bought these because I have not been able to wear my normal heels to work; the dr. They look amazing and would enhance almost any summer outfit. All the stock stuff is fine but this keyboard can become great once you start changing out the switches. On carpeting, not at all. It was a disaster for exercising.
