These headphones exceeded expectations of many reviewers when it comes to reproducing sonic accuracy. They have a very flat response with neither harsh highs nor booming bass, making them great for listening and adjusting details in your mixes. In his Sound on Sound rerview, Sam Inglis mentioned that these headphones "also seem to mimic the tonal quality of some American monitors, with a very strong upper‑mid range. The low bass and extreme high end are certainly present, but it's the frequencies between about 1.5 and 4 kHz that jump out at you." Even with their closed-back construction, a few reviewers have used these for mixing because of its wide sound stage. Many users found these to be well-designed with very decent earpads and clamp force.


There were a few concerns when it comes to the comfort factor due to their uneven padding on the headband. In these cases, users often replace the headband pads to make them more comfortable.


These are good monitor headphones worth the price, but when it comes to headphones for tracking their are more highly rated options available which you'll find in our guide to The Best Headphones for Recording / Tracking - Closed Back.
