Don't waste your money
I ordered this cuff and it was too small; bunched my ear. Contact seller, her customer service is EXCELLENT by the way, and she made me another cuff.  I finally got it on secured on my ear (challenging to say the least) with some minimum tweaking to the wire, only to discover an hour later that it had fallen off. The seller is responsive and told me to keep the first cuff, free of charge.  I gave it to a friend with tiny ears and she has yet been able to get it to stay on.  I was disappointed because I really liked the item.
