The AirAux AA-UM4 Pro: Review

The AirAux AA-UM4 Pro: Review

And now it’s time to meet the newest alternative to AirPods Pro, the AirAux AA-UM4 Pro!

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?

AirAux AA-UM4 Pro: design, construction and battery

With a very compact charging base and a great matte black finish, the AA-UM4 Pro already shows that it is a quality earphone despite its low value.

This base charges three LEDs that inform battery status and has a USB Type-C input for more efficient charging.

The earphone has a design similar to Apple AirPods Pro, in addition to having a construction aimed at the ear canal.

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.

AirAux AA-UM4 Pro: fixation

Like most ear canal earphones, the AA-UM4 Pro is very comfortable. However, although it didn’t fall out during the tests, the earphone didn’t penetrate my ear much.

It may be that this detail makes the sound quality not equal for everyone.

AirAux AA-UM4 Pro: how to pair with smartphone?

To pair the UM4 Pro, simply open the charging base and remove the earphones. Thus, they connect and are already available for connection in the Bluetooth list.

Oh, the earphones don’t need to be removed at the same time, they have simultaneous playback. So, if you need it or want it, you can use just one earphone!

AirAux AA-UM4 Pro: Functions

Because it’s a simpler earphone, the AA-UM4 Pro doesn’t carry many functions, but you can pause and unpause a song; make, answer and end calls; and use the virtual assistant.

Music Function

– 1 tap: pause/unpause

Call function:

– 2 taps: answer
– 3 taps: virtual assistant
– press 2-5 seconds: make/end calls

AirAux AA-UM4 Pro: audio test, microphone test and delay test

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.

To run the delay test, we took our entry-level smartphone, the Galaxy A01.
This smartphone has much simpler hardware, so the AA-UM4 Pro had a slight delay of about 0.5 seconds in our test.

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.

AirAux AA-UM4 Pro: is it worth it?

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.
