Comparison with the redmi buds 3 pro (30€):
First of all, I bought the libert 4nc from their website for 60€ and, in a few words, the "upgrade" to these was not worth it.
Positives:
- The app is simply perfect, it has all the settings you could want.
- They have single tap, useful for adding other functions, but also for confirmation that the tap was pressed.
- They connect instantly.
- They pick up my voice better during calls.
- The safe volume feature is very good for protection against earrape.
- The sound is slightly better than the buds 3 pro.
- The battery lasts much longer, around 8 hours without taking them out.
- The device switching for audio playback is better, as the sound is not interrupted every time the phone makes a sound (e.g. message, screen lock), but only when you press pause.
- They are more comfortable for running, they hardly come off and, importantly, the ANC cancels out your breathing (with the buds 3 pro, you could hear it and it was somewhat annoying). Also, footstep sounds are not as audible, but this may be due to the shape of the earbuds that protrude outward and distribute their weight better.
Negatives:
- The noise cancellation is practically the same as the buds 3 pro, maybe slightly better at covering the "creaking" of subway trains (I compared it in the subway and gym). So, based on the marketing and videos I saw, I expected it to be much better.
- The NC modes (ANC, transparency) have quite a bit of white noise, even at low settings, which becomes tiring after a while (the buds 3 pro had no ANC at all, only transparency at max).
- Additionally, a significant drawback is that the sound quality changes quite a bit when any NC mode is enabled and the bass and midrange are reduced, resulting in a more indistinct sound (with the buds 3 pro, it didn't change at all).
- When you are on a call, the prolonged tap (or whichever you set) for the NC mode does not work! Instead, it ends the call. In my opinion, you should be able to choose how to end the call with a different tap or be able to change the NC mode differently, because it's not practical to have to open the app every time I'm listening to music with ANC on and someone calls me... (the buds 3 pro allowed you to control the NC during a call).
- The sound leak compensation feature is awful, it seems half-finished. Every time a sound starts, after 1 second, the volume suddenly increases a lot for a short time (earrape) and then drops again. This only happens at low volumes.
- They are quite bulky.
In conclusion, I mainly bought them for the supposed better ANC, but after trying all the different silicone tips for the ear, I didn't notice it. For twice the price, I also encounter another negative, the issue with calls, so I do not recommend them. I would go for the buds 5 pro.
