I've had mine for almost a year now, and I feel like they're a part of me now.
I used mine to listen to music, recording and mixing. Because the sound and the output is so good. The sound is unparalled to any other headphones I've tried, they are crystal clear at the highs without being too sharp, you really hear stuff and details you haven't noticed before, the mids are punchy and clear without sounding nasally or dirty and muddy. The lows are exactly where they should be, without being overwhelming and taking over all the frequencies, it's very accurate, unlike some many headphones that overemphasize on the bass to impress listeners, these aren't that kind of headphones, these are for listeners with high demands on the audio, who want an accurate listening experience of music, who want to listen to the sounds how they were meant to be.
