Chosen Solution
I just replaced my lightning/speaker connector on my iphone 5c. When I first checked the speaker and the earphone connector they were both fuzzy. this morning, the speaker is fine. The earbud is still fuzzy sounding. Should I simply take it all apart and reassemble?
I would certainly open up the phone again and take a quick look to insure everything is okay. You may have made a slight mistake when re-assembling. That said, small parts are known to suffer from poor quality so you may just have dud.
