The product would not take a charge and, therefore, is useless. They are being returned. Also, these are a discontinued model. A newer version is available.

I had high hopes for these, but the charging case does not charge, so the headphones can't be charged, hence they are useless.

Defective product never charged

Only one works and can't get them to connect properly. I would have returned them but I waited too long. Don't waste money or time.
