I have narrow, flat feet and needed a supportive sandal that would give me arch support and also feel more stable than a flip flop. I feel safer listening to music or podcasts but knowing that I can hear things around me. I had a strain in my wrist from hyperactivity and needed a rest - I recommend wrist rests to anyone having wrist pain, and even using a wrist brace while computing, lifting heavy items, playing sports, etc. Achei a construção dele muito boa e resistente (Mas, por favor, vamos ser conscientes ao manuseá-lo, né? Evitar jogar na mochila de qualquer jeito, quedas, pancadas, etc. I didnt read the description fully so when they arrived and started to light up (nice and bright, I may add) we were pleasantly surprised. If I manage to find a fix I will post an update but until then I couldnt recommend this device. I also like that the metal is padded to avoid damaging the door. This is a nice solid case with a middle Velcro strap to protect the headphones. I had a long drive directly after my flight and these were perfect. Im on my feet at least 12 to 13 hour days in a kitchen and they are amazing!
