I've been using my 6s for about 2 weeks now, and while I'm quite happy with it and was fortunate enough to get a cosmetically flawless device, as well as one with the TSMC A9 chip (if that really makes a difference), I gotta say that I'm rather disappointed with the audio quality of the speaker. I'm coming to the 6s from an iPhone 5 and the positives far outweigh the negatives, but the sound quality of the internal speaker is pretty subpar in my opinion. I'm no audiophile, but the speaker on my iPhone 5 was clearly louder and richer sounding. Granted, I'm not using the speaker a lot, but I enjoy listening to the occasional podcast or Spotify while doing something that requires me to go without headphones. Anyone else having this issue? Is it a software problem maybe? I don't believe there's anything wrong with the device itself, as others reviewing the 6s online have noted the audio, even when maxed out, is noticeably quieter than that of the 6. I'm a bit perplexed by this.
