I come to make an evaluation after 3 YEARS that I had them in my possession.
The music quality was very satisfactory for their price! Good bass, all fine. And satisfactory volume, they go very loud that you have to lower them.
The fit in the ears, in terms of pain, no problem, I have small ears, after hours of wearing them they never hurt me. BUT, when you start sweating, say goodbye to them, they don't stay on very easily, you have to wipe them (like your ears) so they don't slip. Then they fit well again. (So for exercise, running where you will sweat, they are definitely not for you, they are for more stable activities).
Calls: I could hear my caller, they couldn't hear me well, I had to shout. Terrible microphone.
The connection to my devices was mostly fine, but sometimes it did its own thing, one connected immediately, the other had to be connected manually. (of course, after three years now, they started needing frequent factory resets, I think having both earbuds in the case and pressing both continuously for several seconds).
Their touch was EXTREMELY sensitive. I was drying my hair and a few wet strands were being caught as fingers and the music kept stopping, and vice versa. There was no setting to change songs, only stop, play, and answer the call, I think you can only end the call from the phone. (So be careful if you don't want to answer the call, due to the sensitivity of the touch, hahaha.)
LAST YEAR I WASHED BOTH OF THEM (WITHOUT THE CASE) BY MISTAKE IN THE WASHING MACHINE, FULL WASH. The earbuds opened normally afterwards, as if nothing happened!!! Tough!!! I don't know what others say, unfortunately I mistreated them, beyond the one wash in the washing machine, they fell countless times on their own, and nothing happened to them. So for over a year more, the earbuds were fine. (However, I feel that water played a role after a year and a half, but it could also be due to natural causes, because they had DAILY, EXTENSIVE USE, WITH MISTREATMENT. They lasted 3 years though).
I give 4 stars, because they have good durability (a whole washing machine and hundreds of falls), and I was satisfied with the sound quality in music, series, and so on. If they are for activities where you are around the house, but also for walking outside, they were fine (ideal to be still basically) and you want them for music use and NOT for calls, then they are value for money.
The reason I am changing them after three years? The right earbud stopped charging two weeks ago, and it only lasted 25 minutes. Unfortunately, because obviously I would have kept them for a little longer. These are a few things from me, I gave a full experience.
