I needed couple headphone wall mounted hooks and for the price ended up buying this kit of 4 and couldnt be happier. I have not tried the receiving feature. So I Turned That Off. It makes the long meetings when working from home bearable. I ordered by the sizing chart in the description. I can understand hardware limitations but the compatibility claims are weak. I purchased the mount along with the matching phone case, well designed and made. Id go with one of the other key types (probably linear). Very worth the price. I?d love the option for a refund/replacement.
