My previous phone was a 5 and the audio sounded fine. Now I have the 6+ and for some reason, at low to medium volumes, the audio (when using the speaker) sounds distant and muddled. At higher volumes it's not really a problem. I've not tried it caseless, but i've used two different cases and have had the same problem. Am I alone here? It almost seems like the audio is directed away from me or something. Thanks!
