I've had the Nano for 7 months and I'm delighted!
Is it bright? Sure, it took my brain a while to assimilate those high frequencies. With good balanced cables and a powerful amplifier, the sound opens up, is more transparent and easier to get used to its brightness. Now that brilliance is addictive
.
That's why I don't equalize them, or very little. All the equalization models that I have tried, for me, take away their essence, the shine.
It is important to clarify that bright is not irritating or annoying to me.
Of course, they are also very fast, dynamic and have a wonderful bass. I mainly listen to electronic music and with this genre they make a perfect couple. I would just like more separation between instruments, and a more natural tone. So much shine gives them a special tone. This tone, and the large amount of detail, can sometimes be misleading, I think it is what makes the Nano have its detractors. By this I don't mean that he has an unnatural tone, rather I would say that he has a particular personality. I repeat. I love it!
This is just my personal journey with the Nano, I think that in the world of headphones, each person tells their own experience, and trying to find a single truth for me makes no sense
