I have had these headphones for a year and a half now, but it's time for their crisis.

As for the sound, I don't have a particular opinion. I am the opposite of an audiophile, as long as the sound quality is good and there are no disturbances, I'm happy. I had some issues with the conversation, but it's not worth mentioning. Their battery life is very good, and even now, after a year and a half of almost daily use, if it has decreased, it's barely noticeable.

But now, with the small daily annoyances they have caused, I want to throw them against the wall.

Early on from their purchase, they would sometimes have an issue connecting to the phone. I had to put them back in their case and reset them, and then pair them with the phone again. This would happen periodically, once a week or once a month. I don't understand how something like this can happen with headphones that cost over 100€, when it didn't happen with headphones that cost 10-15€.

Very often, from the moment I put the headphones in the case, they would turn on, even though they were in contact with the charging terminals, resulting in the battery of the case being drained.

Conversely, very often I would put them in the case and they wouldn't start charging. There is no easy way to confirm if they are charging, so I might jiggle them until I see a light turn on, but many times this movement causes the earbud to open because it makes contact with the charging terminal once but then loses it, so I have to take it out, close it carefully, and put it back in the case so that it aligns correctly with the charging point on the first try, otherwise I have to repeat the process.

I don't know if such issues happen with other headphones, but from what I have seen, for example, the case of Xiaomi headphones doesn't allow for incorrect placement. In those, the earbud fits snugly in the case, even though it has a magnet that is supposed to hold it in the correct position, I can say that one out of three times the earbud won't fit properly unless you stop everything you're doing and carefully place the headphones in the case.

I think instead of these, I would prefer to buy 2-3 pairs of 10-15€ headphones and have roughly the same battery life with much less annoyance.

Well, after over a year of use, it's time for my own evaluation. The sound issue is purely subjective since everyone has their own "perception" and their own "ear".
My evaluation is based on comparison with the Sony 1000xm3 and the Jabra Elite 75t that I have and use simultaneously.
Their sound overall is at high levels without exaggeration. Full, with intensity and crispy as much as I need, but it doesn't become outstanding (like in the corresponding categories of Sony and Jabra).
Their battery life is satisfactory (they last as long as they claim). The connectivity is good, but not instant. There are no losses or disconnections. The application still needs a lot of work and doesn't seem to be supported enough (updates). The packaging includes a total of three pairs of ear-wings and seven pairs of ear-tips (different sizes, along with the ones already on the earbuds)... so it's difficult not to find the set that fits properly in your ear.
The hear-id personalized sound, which is done through the application, is a bit gimmicky (I compare it to the equivalent of Jabra, which truly transforms the audio result for me).
The call quality is clear with minimal noise on the other side (okay, if you're in a noisy environment, don't expect miracles).
The case is quite bulky (like the Sony 1000xm3... but there, the battery life is twice as long).
It's important to mention that it doesn't support multi-point pairing (connecting with more than one device simultaneously).
With the wireless charging I use (I also bought the Anker Power Wave Pad A2503), the device noticeably heats up!
In the past week, I noticed some interference while watching Netflix/Prime Video. I thought there was a problem with the TV (but in the end, there were no interferences and my other TWS earbuds work flawlessly).
In communication with Anker, a replacement package with new earbuds has already been arranged and is on its way. I didn't have to send them somewhere for inspection... I was only advised to recycle the infected ones (along with their packaging) or dispose of them responsibly (?!?!!!!!!).

I am quite interested in technology, specifically headphones. I will be brief in my comment. Simply put, their sound is unbeatable and unmatched for anything under 130 euros, just like the soundcore application. If you want headphones primarily for listening to music with a satisfactory microphone, huge battery, wireless charging, and other goodies, here you go. These headphones are the best in sound reproduction. If you find them for 70 euros, you're stealing. I also have the Edifier Neobuds Pro, which reproduce sound with LDAC. I can confidently say that they perform much better and there is no comparison between them. Fortunately, these specific Edifier headphones have other advantages and are a perfect headphone combo. If you want something similar in overall value, check out the soundcore liberty air 2 pro. And if you want something almost perfect for all situations and tastes, go straight to the soundcore liberty 3 pro, which outperforms almost any wireless headphone on the market. For more affordable options, go for the soundcore life P3!

As a conclusion, the music reproduction, high sound fidelity, and audio performance are almost flawless. The 11mm drivers provide an exceptional soundstage for these small earphones. The bass is deep, clear, rich, and powerful, never distorting even at maximum volume. It has noticeable power even at low voice intensity. It guarantees satisfaction for bassheads. In R&B and hip-hop songs with particularly heavy, abundant bass in their composition (a few isolated cases), there is a slight masking effect on the mid frequencies. The lows are strong and cover a wide range of mids in these cases. The vocals from the Liberty 2 Pro are always lively, crystal clear, and dynamic, just like the high frequencies. The mid frequencies are full and detailed. They do not forgive music or sounds of inferior quality, such as poor recordings from YouTube or similar sources.

The construction is durable, made with high-quality materials. It comes with 6+1 pairs of different-sized ear tips and 2+1 pairs of wings that secure the earphones in the ear canal. The charging case also functions as a wireless charger. The passive noise isolation, provided by the ear tips, is quite good. The autonomy is 5 hours and 10-15 minutes at maximum volume with uninterrupted playback, with the right earphone running out of battery slightly earlier than the left one. The case can fully charge them 3 times, but almost never 4 times.

There are dual microphones on each earphone, which may cause slight interruptions in the sound when speaking. You need to speak slightly louder because the microphones do not pick up certain frequencies and below. Generally, this is not a problem.

The Bluetooth connection is stable, reaching almost 15 meters in a straight line without obstacles. They connect to one device at a time. They do not fall out of the ears unless you are doing capoeira training. They are unaffected by sweat or walking in normal rain. When playing audio from videos, movies, or video games, they have an immediate response and do not delay the sound.

You can use a single earphone, either left or right. After approximately 4-4.5 hours, they become uncomfortable and need to be taken out for 2-3 minutes to rest the ears. This is not due to weight but rather the fit. They may appear somewhat bulky on a refined, normal-sized head, but they fit perfectly on a watermelon-shaped head like mine. Sometimes, I detect white noise at low volume. It is not bothersome but becomes noticeable. There is also the Soundcore app, where the sound reaches a whole new level. It offers 34 sound styles, including custom, professional, and personalized earphone options. It also includes the ability to change the energy (command) from the default setting, which is controlled by the single button on each earphone. Software upgrades are also available.

The Liberty 2 Pro may be a bit pricey, but they are not too expensive considering the quality they offer. They are paradise for music, movies, etc., but they could be better for calls and communication.
