So I had to improvise. Fit perfectly and a lovely colour. It has magnets so basically self held on roof then I routed the wires alongside cab and into cigarette lighter. I had to buy a backup pair for when his current pair for so he wont go without! This product arrived on time and was exactly as described. it really looks good. When I take a picture audio stops otherwise this video would have awesome Johnny Cash sound track ⁃ The Aftershokz Titanium headphones have a bad reputation of being brittle if not babied during storage and if you intend to have the Aftershokz for a while, this case is a must have. So I purchased the size 4. And Im not some EDM, base-obsessed audiophile, but seriously, the sound just lacked so much fullness.
