During the fall of 2016 I received a complimentary iPhone/Apple Watch dock from a company called 1byone. While I really liked the dock and overall gave it a good review, I realized that I could improve it with some simple modifications. Several of these modifications were very specific to this dock, as you can see in the video above. While I won't go into the details of those modifications here, one of the modifications could be applicable to many different iPhone docks on the market.
The fall of 2016 will be remembered for many things, but for iPhone users it will be remembered as when we lost the most basic of ports (the humble headphone jack). iPhone 7's ship with special lightning headphones and an adapter to convert from a lightning port to a 1/8" headphone jack. However, if you want to charge your phone while listening to music, you're out of luck with these included adapters. While Apple's docking stations have a headphone jack built into them, third party docks often don't have this feature - yet. In this Instructable, I will show you how to add a headphone jack an iPhone dock.
There are numerous inexpensive lighting to headphone jack splitter adapters on the market. These splitters split a male lighting jack into a headphone jack and female lighting jack, which allows the phone to be charged while simultaneously playing music. I purchased this splitter adapter from amazon. The first thing I did to the adapter was cut the wire leading to the female lighting jack in half. The female lighting jack was set aside for some potential future project.
