Well The iPhone 7 doesn't come with headphone jack anymore, one of the alternative solution can be to Hack a u8 Bluetooth smart watch and add a headphone jack so you can listen your music wirelessly through smart watch from your iphone .
Its a new way to add headphone jack to your iPhone 7 ! it's certainly better than having a no headphone jack . The U8 Smart watch only costs few $ so it will not break your banks and not easy to loss unlike apple's new airpods @ $160 !!!
we will instead use bluetooth smart watch to do the job !

Step 1: Install 3.5 Mm Audio Jack
Everything is self explanatory here , i took apart u8 smartwatch by removing its back metalic plate and 4 screws , inside you will found a loudspeaker , we will replace it with similar sized 3.5mm audio jack connector ,This watch gives only mono audio output so i connected right and left channel togather .
Step 2: Few Adjustments...
in order to fit the 3.5mm audio jack into the watch you need to make few round cuts into the body and it will almost look like a professional one !
Step 3: It Works !
Yeah It works really good just connect the watch with the Bluetooth and you're ready to go !
