I did get alternate boxes by mistake and the seller was super sweet and took care of it! With zero instructions. They may be better at calls than I thought. They have a deep base. Recessed with a protective plastic guide, the cable fits well into the slot, so no worries. Samsung have up their game with these. Im bummed because theyre cute and would work well with many outfits. IDK if i would recommend it for everyday wear. Maybe this works when towing a trailer but with a bike rack there is too much play between the hitch extension and the autos hitch. But for those of you out there considering purchasing this product you should know it basically serves TWO purposes, and based on what youre using it for depends on how the volume control buttons on the Stereo Headset Adapter will work.
