A low-cost earphone that brings a tough finish, improved battery life, and the promise of great sound quality.
Is the UM4 Pro really a good earphone at a good price?
This base charges three LEDs that inform battery status and has a USB Type-C input for more efficient charging.
It’s a very stylish earphone that has a ipx4 protection against splashing water and sweat.
Plus, UM4 Pro carries an autonomy of 4 hours of continuous music playback.
We expected this autonomy to be a little better, but it is within the current average.
It may be that this detail makes the sound quality not equal for everyone.

It’s time to test this earphone that promises to be a low investment for great quality!
In our sound quality test, the AA-UM4 Pro proved to have a great volume level.
Because it didn’t look well molded, it delivered a quality with more prominent highs. This does not mean that the other tones are not clear, nor that this will be everyone’s experience.
After all, when I pressed the earphones, I could see great sound quality with powerful bass.
When tested on a intermediate smartphone, it did very well and showed no delay at all!
And to end our tests, we did our long-awaited microphone test!
Although not perfect, the microphone delivered a good volume level and an audio suitable for home use. It has little muffling and some hissing, but it is quite audible.
It depends on a few factors.
The UM4 Pro is an inexpensive earphone that carries a great design and finish.
Depending on your ear canal, it also delivers great quality. However, it could be that it doesn’t mold well and delivers defined tones, but with a more prominent treble.
Finally, if you are looking for a microphone for games or calls, this microphone can be used, but I do not recommend it for video conferences.
