I haven a headphone which is not this one, but it's called C-45 which is on-ear headphone that I bought from Amazon and built by same company, Lasmex. I did a little research about this company, Laxmex. Apparently they are German company and they don't sell much of their products in US. I made a lot of wired headphones that are over-ear and on-ear, Bluetooth, and monitoring headphone as well. But it is still hard to buy some random product where you cannot find an review for the product what so ever.
