Has pros: Design. Ease of wearing. Good sound quality. Ease of management. The sound is much nicer than in XM2. Everyone has already written about noise reduction and promoted it, but itโs great. With its cons. For some reason, in this version, Sony decided to finally score on PC users. Headphones still cannot be connected as a USB audio device to get the acceptable sound quality they are capable of. The codecs of the AptX family were also removed, which automatically made the sound quality when connected to a PC lower than it was in XM3. Also, to work with PS4, you need to purchase additional equipment if you want to conveniently use them without wires, without losing the functionality of the microphone. In general, the versatility of these headphones raises many questions. If you want to buy some headphones for your phone, PC, TV (consoles), then it is better to consider other models.
