earphone not work
keep having "pop" sound while using B&O earphone with adapter on iphone 7+
iPhone 7 Plus, iOS 10.2

Have you tried the adapter with any other earphones? This can troubleshoot if it's the adapter or a problem with your earphones. What about the lightning headphones that came with your iPhone?
You may have gotten a defective product. You may want to contact the manufacturer and ask for their troubleshooting steps. Or ask for a replacement.
You can also check this article, it is for a different topic but I would still suggest the steps:
