Cases yes, attachments---no. But I suppose if you're looking at specific Apple compatible devices then you'll find what you're looking for. I believe the the iPhone 7 has withdrawn the 3.5mm jack which caused quite an uproar, but others are also doing the same. People are scrambling to get USB C to 3.5mm convertors instead of just going the wireless route with BT devices, talk about moving backward! I guess in some peoples defense, they may have spent a fair bit on "wired" headsets and aren't in a position to purchase a wireless set ATT. I use wireless everything, and have been since BT headphones became both reasonably priced and good quality, same with my car, not to mention the tickets for using your phone while driving are outrageous!
