I've always wondered why the Penons weren't as popular among famous YouTubers, or why their curves weren't featured in the online tools they provide. Now more people will know. You just have to see the number of visits it has had at a time. I'm happy for Penon. They have done a great job.
On the other hand, I have a cross feeling. I love music from a very young age. My mother worked in a record store and I spent my spare time there. There are songs that you like to share with friends, that everyone enjoys... and then there are other songs that you like to keep to yourself, that you enjoy alone, that you share with your closest circle of people, and that you love. Suddenly the song is played on the radio and everyone knows it. It sounds so much that they spoil that moment for you.
Something similar happened to me with the 7Hz Timeless, which I had as soon as they came out, before the hype, seeing that they were planar, and having good references from other IEMs of the company. Now I have them parked somewhere and I barely pick them up. Will the same thing happen to me with Serials? No... sure not... I like them too much!!
