One of those products for which the price is stable. Bought 3 years ago in Amazon for 540, now in the same place at the time of writing the review 520 (at a discount). If suddenly something breaks or is lost, then most likely I will buy them, because they have already been tested by time. Unless, of course, the quality of production does not fall over time, and this happens with popular and durable products. In general, for their money, quite good headphones. I read the reviews here and for some reason for many they are quiet. It's strange, my volume is usually a third of the total and a maximum of 75% if there is noise around (metro, bus).
