After reading some posts here about the audio quality of the iPhone 7 compared to other iPhones, I had to test it out. I used the following phones: iPhone 7 Plus iPhone 6 Plus iPhone 5s iPhone 5c I played the same tracks via Apple music and compared them using the Apple EarPods (the ones that come with the iPhone 6 and the lightning ones from the iPhone 7). Example "Changes" by 2Pac easily shows the differences in audio quality. You can EASILY hear the differences between the 7 and other phones and it is not good. There is a lot less deep bass now and they do not get as loud. I have no idea why but it was the same using the following: EarPods with lightning cable connected to all phones EarPods with standard headphone cable (without adapter) EarPods with standard headphone cable (with adapter for iPhone 7) All scenarios with the phones came out the same, the iPhone 7 is lacking the quality audio compared to the other iPhones. It sounds like having a nice audio system with an amp when using the iPhone 6 Plus or even the 5c. But when you listen with the iPhone 7 Plus, it just lacks the clarity, bass, and "oomph!". Go ahead and try it, super easy to hear a difference and everyone should have multiple EarPods. Major disappointment.
