AKG Acoustics K612 Pro Reference Studio Headphones, Patented Varimotion Diaphragm, 12-39500 Hz Frequency, 120 Ohms Impedance, 1/4" and 1/8" Screw-on Combo Jack

Great sound stage and localization. Extended frequency does matter and these cans have it. Extreme low and high frequency noise stay out of the audio band..... very clean sound. Excellent for post mixing and mastering.

I've been struggling with singing using headphones, as they just didn't allow me to hear myself accurately. After years of using semi open and closed back headphones, I decided to give these pair of open backs a try, within a few minutes of using these bad boys my performance improved significantly.

These headphones are amazing. Coming from the AKG k240 headphones, these are so much more open and wide. You can hear more detail and clarity. The thing I dislike is not having a detachable cable so I have to be extra precocious.

this headphone give a wide sound stage be open back, great dynamic range, killer Mid-range and highs and sub bass. this bring out best in the Focusrite VRM Box.

Very nice headphones, comfortable to wear, light weight, clear crisp sound.

sound 5/5 durability 3/5 best sounding headphones EVER. unfortunately after a year and a half, one of the ears stopped working, however it's build quality / aesthetic and "feel" is top notch. I was probably unlucky.

I like 'em. Quality build and comfortable. They take a bit of driving so be warned. If you are dual monitoring from the same source you'll notice this, and if you are using them with a mobile device you'll want a headphone amp. Quality cans though.

I've been on the look out for a decent pair of headphones for a while now to replace a much more expensive set that died a death. I was a little skeptical of the k612 pro series as some of the reviews elsewhere question build quality (fixed cable etc) however I am so pleased that I took the plunge.

mega brill headphones the sound quality is mega good well worth the cash but sorry to say the right speaker died after only 2 months of use and the build quality not that good....

Good, cheaper alternative to the Beyerdynamic DT990s
