In my country where taxes are very high, all headphones are very expensive. However, this time, after waiting for stocks for 1-2 years, luck smiled on me. I bought 2 of these headphones, which I knew about thanks to reddit, and then bought 2 more after listening to them. I made a headband pillow for one of them by hand, it is very comfortable now. Even though I have many headphones including Sennheiser HD800, I am very satisfied. I wonder if their pads will last on the shelf for 4-5 years? So should I stop at 4 pieces?
