By the beginning of January 2022, I acquired it for the price of 1,790 r. Before to that, there was the JBL E45BT series (the price is now about 2500). As a direct consequence of this, the sound of the 500s is one magnitude more bass, one order of magnitude more treble, and one order of magnitude deeper (I don't know how to convey this concept:)). Even equalizers are unable to produce bass tones of this magnitude on the 45th. They maintain a stable position on the head, which is a significant plus, but the pressure they exert becomes noticeable after about an hour and a half of wear. When worn around the neck, not only is it uncomfortable, but the clasps also press. As a direct consequence of this, the headphones are fantastic for the price. I advise.
