Length: This cord had plenty of length with several feet to enable this connection. First they gave me a return code that the local staples couldn?t use (wasted hour). I have to say. Will definitely get more as my collection grows. I really recommend it. And she absolutely adores them! 11-12 I got medium. I really love mine, the little bows at the back are fixed bows, and are so cute, and no Im not 16, Im in my early 60s! Time for the pros they last for 7 hours without needing to be charged, once you pair it the first time you wont have to do it again it automatically will do it all you have to do is take out one of the earbuds out of the case and it will do everything automatically,These are decent for bass. It feels very solid and sturdy.
