When I first got the iPhone 7, it was kind of like: hey if Apple includes an adapter, how bad can it be? For the first week or so, it wasn't bad. Now I've had my 7 for over a month and I've noticed the amount of music I listen to on my phone has significantly decreased. I no longer use headphones (or take my phone for that matter) when I work out or run because I've gone to the gym a few times and forgot the adapter; granted that is my fault, but it's still annoying. I've tried wireless headphones which I ended up returning as I did not like them, I didn't feel the quality was very good in comparison to the wired headphones that I have. Also, really disliked the fact that I would've had yet another device to charge.
I upgraded mostly for the iPhone 7 water resistance and the overall speed benefits, plus I wanted to downsize from a 6s plus to a 7. But the headphone jack is more of a compromise than the other stuff. I'm still extremely careful with my device around water or while outside in the rain and the overall speed benefits I can't really notice a difference. In the end, the only thing that worked out well for me was the downsize.
The iPhone 7 for me is now about a compromise that I never felt I had to do before with iPhones. If I want the things I like on the iPhone 7 (screen, stereo speakers, home button, water resistance peace of mind), I have to learn to use the adapter, get a pair of wireless headphones further compromising as it's another device I have to remember to charge, or just not listen to music through headphones on the iPhone 7.
As I've said throughout my post, it's just a huge compromise now I feel, I guess living with whatever I feel is the least compromise. I'm still undecided as to what I will do.
