Is it that you can’t enjoy better sound quality using the iPhone? (alien.top)

Because it only supports aac and there’s no headphone port, you have to use Bluetooth for music, the sound quality is greatly compromised, it doesn’t matter what headphone you’re using.

Lack of power is often simply a volume limitation, or in rare cases, non-linear distortion (a certain harshness to the sound. You can check how increasing levels of THD sound like in a test site like https://www.audiocheck.net/testtones_thdFull.php)

More likely, when in Bluetooth mode, your headphones apply digital signal processing, most often to improve channel balance (to compensate for one cup having the electronics etc.) but also to tune the sound further.

It's an especially prominent effect in many ANC headphones, where the microphones are used to determine what correction to apply to the sound go get the intended frequency response. If same headphone is connected passively, none of this processing is working and whatever improvements could be made via DSP are gone.

Does you headphone have an app with equalizer? If yes, see if you can boost the treble in the bluetooth mode.
