Headphoneus Supremus
From GSM Arena. The output doesn't seem ruler flat anymore.
Very good audio quality, not quite the best
The Apple iPhone 6s audio output is identical to that of its predecessor. Sadly that's not very good news as last year Apple took a step back in that regard, and unfortunately it failed to patch things up now.
When plugged into an active external amplifier, the Apple iPhone 6s posted excellent scores with the rather mediocre stereo crosstalk reading being the solitary exception.
Rather impressively, there's virtually no degradation when you plug in a pair of headphones. The spike in stereo crosstalk is so limited that in comparison, the iPhone 6s fares way better here than in the first test. Granted, there are phones out there that do even better, but that will only matter to the most extreme audiophiles.
In both cases, volume levels were above average although Apple used to be class leading here too and now it's just matching most competitors and falling behind the elite. Still, the overall output is very good and would please the majority of users.
Anyway, here go the results so you can do your comparisons.
