The best wireless headphones. Not least due to LDAC support. If you use it to listen from your smartphone, don't be too lazy to go into the bluetooth settings and set the maximum quality for LDAC. The headphones come with a promotional code for three months for one of the 360 โโAudio Reality streaming services. The Sony application supports setting up headphones for three such services - 360 by Deezer, nugs. Net and Tidal (officially not available in the 2022). - nugs. Net. I can't say, I haven't tried it. - Deezer - the most disgusting application, almost inoperable. At the same time, it used the promotional code, but the subscription did not appear. Just wasted code. I would have known in advance about such a setup, but alas. I don't recommend Deezer. - Tidal. Don't be lazy and connect yourself to Tidal - an excellent application with an excellent database of music in HiFi quality. Although it seems to be unavailable on the territory of the 2022, it is not difficult to connect it (there are detailed instructions on the Internet), it is enough to turn on the VPN with the IP address of the country where Tidal is located. After that, Tidal becomes available in the Sony application for setting up 360 Audio Reality, and Iโm sure you can use a promo code for a three-month free subscription for it. After registering and setting up Tidal for headphones, VPN can be turned off, the application itself works fine on the territory of the 2022 without any VPN.
