Apple will sell replacement Lighting port to 3.5mm jack adapters for $9 apiece
A small accessory by nature, it will be understandable if you eventually lose the adapter, or it simply stops functioning – after all, it's mostly cable, and cables are known for breaking and twisting.
Thankfully, Apple will be selling replacement adapters at the very reasonable price of $9 apiece. The item is already listed on Apple's website, although its specified as currently unavailable. So, there you have it – it's good to know that this accessory that many users might find rather essential won't cost an arm and a leg.
