Replaced my ATH50 with this one in my home studio, a very solid build. Requires a proper sound card that can drive the headphones due to their medium/high impedance (250). They are not travel friendly in any way shape or form, can't be folded so just be aware of that. Also, if you're coming from the ATH50-world, please note the difference in mid-range response. Takes some getting used to, but I like my new normal. :-)
