Sound Quality on the FiiTii Mifo O5 Plus Gen 2 Earphones?

This earphone has a full-range Balanced Armature that well tunes a balanced and authentic sound with fine details, these are quite good for people who like to listen to bass-heavy and rock music tracks, also the vocal music output feels nice out of these earphones, as the highs and mids are balanced out.

The moving armatures on these earphones transmit the audio signal to the center point of a miniature diaphragm through a link rod with a small structure, thereby generating a sound unit that vibrates. Giving a higher resolution than the dynamic unit, with better detail performance and better-balanced frequency.

We would have been glad to see an App for Sound EQ customization, but given the fact that most people are happy with the default EQ settings and rarely use the App, it is not a big deal, but some people like to customize the sound according to their own hearing preferences.
