I use them for 5 or 6 years. headphones for farm, they have made exceptional highs. The ensemble is equilibrated trs. Never a musician complained. They cash in a lot of power. I'm even happy in my mixes rcoutant above. Trs enjoyable.
Even when they have a terrible default: The plastic coating dsintgre after 5 years of careful use. It's annoying to have bits of black plastic Tranent on the ears and hair. Now that the price is lower, I would buy if I found a way to empcher to dsintegrer.
