In this podcast, Scott Davert compares the iPhone 6s with the newly-released iPhone SE. It's recommended to listen on a decent set of stereo speakers or headphones to get the full effect of the podcast. The one point he did not mention in the podcast was that the battery life between the iPhone SE and iPhone 6s appear to be about equal.

Scott also has recorded audio files with the Voice Memos app. You can fine the iPhone SE's recording here, while you can review the short clip of the iPhone 6s at this link.
