It's a shame those Anbes are NLA!
My wife loves them! At least for her, they were perfect. And, for me the price was perfect. She has used them for 1.5 years now. 1 time she had to jump through some hoops to get one of them resynched, and 1 time I had to do a little cleanup on the charging contacts to get one of them to recharge properly.
If they were still available, I likely would have given some as Christmas gifts.
