Well people. I dont know if you, but if you pruchase a good headphone where you want to get all the BEST, mods for improvement are practically an obligation. so Make a ranking full moded headphones, with mods that exist in youtube. evaluated in the same criteria thay you use for regular ones. Often, very often, the mods are very cheap. Even exist mods that just consist to put a tape in the driver or remove a sticker, which actually it is free. if there is no mod, well, you can decide to use other mods that you have found for other headphones or just donโt put it in the ranking
