iPhone 6 headphone jack and battery

I replaced my iPhone 6 battery today and it went as expected. Didn't run into any problems but then noticed my earphones weren't working nor does the speaker for the phone when held to the ear. Sound and calls only are heard from the main speaker. The phone recognizes the headphone when adjusting the volume and the headphones work fine elsewhere.

So any ideas? Can replacing the battery affect the headphone jack and phone speaker??

Thanks in advance!
