These are a good headphone and I do enjoy them. Though I do prefer another one that is at the same price, but it is closed back but I think just better overall with how it presents the sound and definitely better bass ( but closed vs open has a play there )
VB-DropLSA HP-2 ultra. A small company that does audio equipment that I believe mostly is rebranded.
I know the headphones are rebranded as they state it. They state nothing has changed from the original but people that have heard both state otherwise. Though doesn't matter as the headphones are good and you can find some boards about them.
Again the Meze 109s are good, just too my ears I prefer the HP-2 more.
