Sure, it's not a bad DAC and I'm happy with the sound on wired IEMs. It's just that I could drive my high impedance headphones straight from an iPhone SE and I can't with an iPhone 8. I lost functionality.

According to those measurements the adaptor's DAC is fantastic, especially for a $9 part.
And in the spirit of anecdotes, the old iPhone DACs were notoriously hissy and weak, and if you're buying high impedance headphones you have no business plugging that into a phone's headphone jack... spend the $20-50 on an amp/DAC and call it a day. Just a bigger dongle.
