If you have an iPhone 7 and it's driving you crazy not to have a headphone jack, you may want to check out the Fuse case. This is an Indegogo product so we don't know if it will actually make it to market, but the Fuse case is going retro. It's a case for the iPhone 7 that will allow you to use any standard headphone jack with your phone. You know, just like we've been doing with every other smartphone on the market for the last decade.
Check out the video and see if it's right for you. You will have to pony up some money now in hopes of getting this case delivered sometime in the future.
I hate not having a headphone jack, but I think I'd rather move forward than backwards.
