So, I bought these headphones several months ago and I have to say the following: Very good clean crystal clear sound, satisfactory bass and treble, the cable is designed in a way that doesn't tangle, very nice finish and metallic elements, comfortable and convenient to wear but... completely disappointing and of poor quality in terms of functionality and durability. In less than a year, the right earphone completely broke and stopped working. At first, it had interruptions and then it completely stopped producing sound. By shaking the cable at the base of the plug, it might work for a few seconds, but that's it. I regret buying them because besides the good sound quality, you naturally pay for durability, construction quality, but mainly for the lifespan, something that these in-ear headphones unfortunately don't have. You pay, and after a while, you simply don't have headphones anymore. Don't trust them. Pay a little more and get more durable headphones that will last you a long time and you can enjoy them. Unfortunately, a very bad purchase.

I read on Amazon from many users that after a few months, one of the two earphones stops working, and I'm here to confirm that it's true. I thought maybe they happened to get defective ones, but it seems that it's actually a series defect because I didn't even use them frequently. It's a shame because the fit in the ears is perfect without causing any discomfort even after hours, and the sound is very good, although it's not very loud - it requires adjustment in the equalizer for each genre of music for the best sound. All in all, it's a mediocre product that would have been simply perfect if it were more durable.
