They ran a little large on me, but I like thick socks I again ordered the same size. The product itself isnt bad, but the directions are horrible. Very good seller, good communication. They fit into my ears perfectly, which is saying something because I have small ear canal openings and most earbuds keep falling out because they do not fit securely. Really sad that they couldn’t provide support on this product. Overall, Id give it a 9/10! The Bad- they are not comfortable for long walks. Angesichts des Preises fange ich dennoch mit den Mängeln an, denn ich habe diesen eher preisintensiven Fahrradheckträger gewählt, um ein Rundum-Sorglos-Paket zu erhalten. I was disappointed with this pair! All I had to pay was about $5 for shipping.
