I sadly dropped one of my liberty air 2 pro headphones into the toilet while flushing, so I needed new headphones. I grabbed the 2 at 80€ before but now they are at 130€ aswell so I though I might aswell get the next generation ones for the same price, sadly the noice cancellation is worse than on the 2 pro, and they are also my most liked feature. To be fair the sound is good on the 4, but the heart rate feature not really needed. They are decent headphones, but if anyone has a spare 2 pro headphone for the left side, hit me up 🤣
