The 05 offers a better image quality. Each earbud in the MIFO O7 has a carbon nanotube, and dynamic speaker drivers, for highly precise and large sound at all frequencies.
When taking calls, the 05 includes numerous microphones and voice refining software. It incorporates haptic touch controls and Qualcomm's newest Bluetooth 5 chipset. If you answer more calls, the 07 is preferable.
If you enjoy listening to higher-quality music, the 05 is for you. Both are excellent; it all depends on how you utilize them. Hoping this MIFO 07 review will help you decide.
