Let's start with the fact that these are my first such expensive headphones. I've never dealt with such expensive studio equipment. Okay, maybe it's not that expensive compared to the available high end models, but for someone who has had headphones for 40 euros max all his life, ~225 euros is a lot. What weighed on my choice was the high-quality workmanship, which is solid, minimalist and aesthetically pleasing. I very much respect the metal parts that reinforce the sensitive areas. Although the rest is ABS, it feels like it's made of good and solid one. As for the materials used, I have no complaints. Let's move on to the sound quality.
If you set yourself to listen to music from your phone through these headphones, maybe you should choose some other ones. I myself also use them in this way, but the sound quality is much higher when I use them at the computer, played through the interface. Also, for listening to music, to make it satisfactory, you'll need an equalizer to bump up the bass a little bit, as the headphones sound very neutral and have subtle stock bass. I don't see this as a problem. Just like a guitar amplifier, you have to adjust them properly to make the sound satisfy you. And when mixing and listening, this neutral fireworks-free sound is just an advantage. Overall, I rate the sound quality as very high. It is very clear and detailed, really a skyrocketing difference from ordinary travel headphones.
As for comfort, they are super comfortable. Any over-ear headphones I've had have pinched my big head to the point that the pain was unbearable. In these headphones, I spent literally the whole day recently, and on top of that I fell asleep in them on my head. And guess what? Nothing comically hurt or pinched me in the morning. They really are very comfortable. It is known, it is subjective we have different head sizes and shapes, different ears and such, but as for me, they are the most comfortable headphones I have ever had on my head.
So, I recommend for anyone who starts the adventure of mixing. I myself use them just for mixing, mastering, playing guitar, watching movies, listening to music making dinner, cleaning in the cottage, commuting to work and..., no wait, I got a little caught up, but these Yamahas are really great. I recommend the product as well as Thomann to complete the order.
