If you want to buy these headphones to listen to normal music, then look for other ones, preferably without bluetooth. The sound in these headphones is "plastic", sometimes it seems like from a barrel, the upper frequencies are cut off. I hoped that the sound quality suffers only from Bluetooth, but the sound has not changed much over the wire either. For watching TV or listening to something in the background, it may be suitable, but not for music for sure. Listening to music in them will not deliver emotional pleasure. There are Sennheiser MX 170 headphones, the sound is much clearer and more detailed in them, you can feel the “presence effect” in them. There are also old headphones of the 2022 brand Dialog, and the sound in them is better than in these Philips. Oh, and as a bonus to not the best sound, you get the smell of cheap plastic. And it didn't completely fade in a week. In general, I returned the headphones to the store. I bought them for a promotion for 3000, but I think you can get almost the same ones on Chinese sites, only several times cheaper. After the sale of Philips to China, one should not expect good headphones from them.
