In the merits, it says "seemingly", because I only managed to listen to them for 10 minutes, because then I untied them from the dongle, and it did not work out to tie them back to it. Binding to the dongle is carried out using proprietary SteelEngine software, but only on two tested computers, the software did not detect the headphones. Later, by googling, it turned out that this is a common problem with them and there is no guaranteed recipe for it. Thus, the headphones became only wired. The situation was in January 2022, but I doubt that anything has changed since then. Thanks to amazon for returning the money for them.
