I never expected that such device will be the perfect complement for my trusty HD 25. All the cons I picked up upon hearing my HP were all remedied by this wonderful DAP (thanks to its built-in amp). The sibilance went away, better bass extension and mids are among the improvements it gave. Oh, I almost forgot, the soundstage became wider. Definitely a must buy for all HD 25 owners. :)

I never thought that there's such a headphone like this existing! Everything that I'm looking for for a headphone, I found it all on this hp. Cool looks (at least for me), changeable parts (especially the cables), superb clarity with excellent bass response, and lastly, known for its superb durability.  

I'll start by saying I regret buying this HP. I just bought this with me in mind that it's endorsed by some well known personalities (yeah, I'm dumb). I just realized that the sound of it is so muddy after a/b'ing it to my newly bought Senns HD 25.
