For a pair of TWS, the hardware will decide how the earbuds look, and with BA drivers, Mifo O7 can pack it as small and compact as possible and it still keeps the sound above par. Like Airpods Pro the O7 are noise isolating earbuds, they include 5 sets of silicon eartips (together with metal charging case, 5 sets of eartips, type-C charging cable)
With recent development in Bluetooth processor which consumes less battery, the Mifo O7 have about 6-7 hours of playback time, that isn’t among the top long-lasting battery life performers but it’s fair enough given that AirPods Pro have 5 – 6 hours.
Comfort & Fit
The build-quality is solid and secure fit (I stay pretty put in my ear while running or pushing up) and IPX7 rating are great for sports just in case you sweat a lot.
Touch control is responsive – the touch area fit right you finger tip, you can take calls a single touch and with dual mic the built-in CVC tech did a great job to subtract the background noise.
For the sound quality it’s an improvement compared to the Mifo O5, the O7’s sound is much cleaner, tighter and more accurate. The sound stage is wide too.
The bass is there, it’s not that rumbling like dynamic driver but feel tighter, while mid-range is filled with details and sweetness.
Perhaps the treble is the best range, though it’s not that bright since the overall sound tend to be warm.
Take a note even though 3 ranges are not particularly unique but you’ll feel layers of musical instruments (separation from sound perspective)
True Wireless TFZ X3 get the same look as Mifo O7 but more splashy and shinny, they also have dual Balanced Armature, natural, rich, smooth and pleasant to listen to.
