Basically, I use them at the gym where the noise cancelling makes every sound disappear. Also, an important factor in this use is the fact that they don't come out of the ear no matter what and they have no problem with sweat. Other than that, everything is as you would expect for headphones at this price.

I was a owner of the Soundcore Liberty 2 (purchased in 2020) and I was extremely satisfied. The only thing that bothered me was the connectivity issues which were often problematic. In terms of sound, they were flawless. In the summer of 2024, they broke (went into the washing machine). However, being a Google Pixel owner, I decided to get the Pixel Buds Pro 1st gen, and I was disappointed mainly due to the sound volume. I gave them away and decided to buy the Liberty 4 Pro since I researched them from reviews on the internet, however, they were not yet available in Europe (only UK). When I saw them on Kooqie, I bought them immediately (12/27/2024).

POSITIVES

1) I had forgotten how well-designed the Soundcore app is. You wear them and it practically does an audiogram to set the sound based on the user's hearing.
2) They are very comfortable in the ear and wearing them after a few hours is not an issue.
3) The volume of the headphones is amazing. I keep my phone at 60% constantly, since if I turn it up more, I will go deaf. I use higher volume in noisy places so I can hear.
4) Being a lover of electronic music and bass in general, I can say they are excellent. And by adjusting it from the equalizer within the app, you can customize it to your liking.
5) The connectivity that was my biggest problem with the Liberty 2 does not apply to these. The first time you set them up, they appear as a pop-up notification. They connect directly when you wear either one or both if your Bluetooth is on, and I haven't encountered a single problem so far. The multi-device connection feature works perfectly so far, as when I was driving, I had my phone connected to the car's Bluetooth, and as soon as I got a call, I put in one earbud and the sound transferred to the earbud immediately. So Soundcore has dramatically improved this issue.
6) The noise canceling and ambient modes work excellently and I use them constantly.

NEGATIVES

1) If I could mention one negative, it would be the case. I am not disappointed, it just seems a bit lightweight and not as high quality as I would like. However, it doesn't bother me much since it is always in my pocket. It could possibly be a bit smaller. The touch functionality works just fine, but I use it very little.

5 STARS therefore because they deserve it...
Overall, my biggest mistake was not buying these and going for headphones from another company. They are a fraction of the price of major headphone brands (Apple, Samsung, Google) and are truly well-made from start to finish. I am extremely satisfied and I highly recommend them. If you want headphones under 150 euros, don't buy anything else.
