I thought between 5 and 4, in the end I decided to take exactly four, as many wrote that noise reduction and sound quality are better here. I'm not an audiophile, but I like the sound quality, there is an equalizer, with it you can adjust everything as you need. For me, comfort was also important, the headphones are very light, after a while the head does not get tired of them. The soundcore were in operation, so they seemed to weigh a ton in a few hours. There is no such thing here. The touchpad control is a paradise at all. In the end, the purchase was satisfied.
