Review on Upgrade Your Studio Gear with Audio-Technica ATH-M40x Professional Studio Monitor Headphones: 90-Degree Swiveling Earcups, Pro-Grade Earpads/Headband, and Detachable Cables by Keiko Yapon ᠌

Although my ears are heavy, they do not put pressure on my head. You can keep it on your head for a long time, when using it for several hours a day, your head does not crack. Replaceable cords are convenient, especially if you need to listen to music from the player (smartphone) on the way, and then, when you come home, you just need to switch the cord to the computer. The volume is more than enough, the volume margin is very good. Purchased to replace Sony 7506 when they failed. Sony handed over for repair under warranty (they promised to do it within 45 days), without ears it was very sad and depressing. I bought this Audio equipment as a temporary replacement for Sony. But for more than a year they have become permanent headphones. I take Sony with me on business trips.
