I will go straight to the point and then I will go into details.
The headphones are fantastic for what I bought them for.
I wanted a good set of headphones that I can trust both in terms of sound and in terms of build quality and comfort.
I can wear them all day, with or without glasses, even lying down in bed, without a pillow directly on the mattress.
Now, in more detail. If you want, read them and draw your own conclusions.
This is my personal experience.
The truth is that I started to love them lately after a lot of research and comparison with other sites like RTINGS and learning about the limitations that headphones have compared to live sound, obviously good sound systems in suitable spaces without echoes, etc.
More or less, a basic driver cannot do everything and manufacturers are forced to make compromises by tuning in such a way as to achieve the best possible result for the ears of the world.
And so I try to deal with everything.
What everyone wants in relation to the limitations is far apart.
If you take a sound, record it through instruments, convert it into a digital format of 0 and 1, convert it back into an analog signal that will vibrate a drum expecting that you will get the original 100%, then you have not understood something.
You can imagine every sound system as an artistic representation of reality that it projects.
It will never be exactly the same.
So the fact that these headphones come quite close and I am happy to finally listen to music makes them one of my favorite things I have ever bought and I expect to have them for many years (already over 3) and as time goes by I love them even more.
Now I am changing the subject to the purely technical.
80 ohms is in the middle. You can even run them with a mobile phone and on the PC it's okay but the truth is that after I went to an iFi Audio zen air dac amplifier, I simply don't want to go back to motherboard sound.
I bought them with the idea of buying one, and to tell the truth the difference is not day and night as many say. It is not immediately perceptible especially if you have not "trained" your ear to "good" sound. It is not like a 1080 to 4K difference that everyone can see, it is somewhat different.
I will explain it in my own words using inertia as a tool for understanding.
Heavy drums, strings, and small light bells.
You give them energy and they vibrate.
The bells will be heard even with the slightest touch but the drums need a lot more energy.
A good amplifier has the power to play them all correctly without difficulty.
A weak amplifier will struggle, it will produce volume BUT not very uniformly.
The overall sound will be good but some frequencies will be shrill and others will be weak.
So I would say if you don't plan to spend 130+100 or even more, maybe it's better to go up to 32 ohms.
Anyway, if you have never dealt with sound and technical analysis of headphones, don't overdo it.
Set your budget and filter by rating. Take a look at RTINGS to get an idea of the objective rating, because reviews like this one will drive you crazy. Get a good, tested headphone to do the job.
At the end of the day, the important thing is to enjoy the experience. I hope I helped and didn't tire you out. Enjoy listening.
P.S. I changed the ear cushions when needed and it made a difference. The ear cushions matter a lot, both in comfort and sound
