I must say right away that before that I used Philips O'Neill Stretch bought for 2500r in 2022. The first impressions about the M50x are strange - I listened a little, but the sound is normal, everything is in place, but they did not produce any stunning effect. My old ones seemed to play as well. Okay, I'm plugging in my old Philips and I don't understand anything. What happened to them while they went to pick up the order? Are they broken? Have they been changed? Are these not my headphones? No, the iron plates that fasten the broken shackle (yes, they don’t break;) are in place. They just turned into tambourines compared to the M50x. Even on a low quality source, the difference is noticeable. I'm talking about the TV, detachable wires were very useful here - just 3m to the TV. I listen to music on the Fiio X1 player, everything sounds great, I don’t want more yet.
