Purely, their biggest advantage is the sound, incredible across the spectrum. The package includes 7 sizes for the ear tips, the larger you choose, the more isolated the bass becomes in your ear and the treble becomes slightly more closed, the opposite if you go in the other direction, so you try and find the best balance of fit and sound. In any case, the bass is excellent anyway, the best I have encountered in Bluetooth earbuds that I have tried from time to time.
The noise cancellation does a very good job, the more general and lower frequency the sound is (e.g. traffic noise), the more it isolates it (e.g. if a single motorbike with a modified exhaust passes through the general traffic noise, it will be heard).
I haven't made many calls, but the few I made while inside the house, people could hear me clearly, just a bit distant. Now, I don't have an opinion on calls while on the street.
The battery is not something exceptional compared to, for example, the Creative Outlier V3, but in general, it lasts around 4-5 hours. However, with full noise cancellation, it can drop to 2.5-3 hours. The good thing is that they charge very quickly.
Their mobile app has many settings for connectivity and shows the battery percentage of each earbud (as well as the case when the earbuds are placed in it). You can also customize the touch controls, which generally work better than other earbuds but will never have the immediacy of a hardware button.
For those who decide to give them as a gift, their packaging is incredibly premium and impressive, as if it was made specifically for unboxing.
I will finish with the only truly negative thing I found, which I recognize is something subjective and circumstantial. While the earbuds fit well in the ear and do not fall out, for some reason, I constantly feel a slight pressure that I don't feel with other earbuds I have tried from time to time (e.g. I can wear the Creative Outliers all day). I believe it is because their main body is relatively bulky and slightly more angular in some areas compared to others, and the tip of the earbuds that goes on top of the ear tip is larger in diameter than usual, resulting in the ear tip being slightly harder. The result is that I feel fatigue after a while, and I don't know if it will improve over time. I REPEAT, it is purely subjective, they may fit perfectly in other ears.
Overall, these are earbuds that are aimed at someone who primarily wants quality music sound. If you mainly listen to podcasts and YouTube, there are cheaper options with better battery life.
I reserve judgment on their durability and reliability, if something goes wrong, I will update the review.
