Many experienced audio engineers said they have used these headphones to check their mixes for minuscule details due to their neutral sound. They provide an airy and wide soundstage that is nearly immersive. The bass, mids, and trebles are well balanced and it has a very flat response. In terms of comfort, the velour pads provided were very soft and most users experienced zero fatigue from listening for hours.


Since they require a bit more power it is best to use a headphone amp to maximize their sound quality, some users found them to sound thin when plugged into their portable device such as an mp3 player.


These are a great investment if you are looking for high-resolution headphones for referencing, mixing or high fidelity equipment.
