Der Ballerina ist Ansicht groß genug, trage 42/43, nur ist die Spitze des Schuhes sehr schmal. So, we had to send it back. Paired quite easily. I ordered the large too and it was too big underneath the arms. Customer service answers everything really quick. The main reason I didnt give it a full star is because theyre not lighting up when I use them on my ps4, I will be contacting they about this to see why and to make they light up. It fits Prefect ?? I?m sweating already YayCan?t wait to hit the Gym in the morning. I love the fact that the earbuds are waterproof, holds a long charge, the sound quality is excellent, they come with extra ear tips to ensure that perfect fit, and the reasonable price is another bonus. Mine shipped on that day, then Amazon changed the release date to October 23rd, and wouldnt let me post a review because "the item hasnt been released yet". I tried it over 4 times, and each time it calibrated them a very different sound.
