K-612 Pro : Very Good Sound & Reasonable Price

Highly recommended. I use the headphones for production / composition of electronic / acoustic music with computer. I used them already for many years. Very comfortable, nice soft textile pads - much better then the leather / vinyl on some other headphones. I am very satisfied with the sound in general, transparency and stereo image.

Even I have a feeling though that the sound reproduction and imaging is a little bit beautified and more "spacey" then the actual input material ;)

Still true enough for production work and monitoring in my opinion.

The soldering points at the cable's end inside are not the best design. A failure can happen if pressing the left headphone at wrong angle accidentally. But if handled carefully should not be an issue. Also there is a service manual available online and it is an easy repair. I recommend this headphones.
