Hi all! Anyone knows the difference of the new "Cyro Treatment" version from the old one? Thanks!

Hi all DT880 owners, what are your sources and amps for the lovely cans? Feel curious about that and would like to take as reference for my own setup upgrade.

Hi all! I'm doing some essay about headphone. Is there any website that I can dig information from? Like the history of headphone? I tried to search with google but failed to get any clear document... Thanks!

Sorry, I'm not sure if it should be asked here... Anyone knows if the HeadRoom CS responses quick? I've posted Roz mails on the same topic for about 1 week... but there's no response yet. I made my first purchase for 2 cables there... but maybe there's some mistake so they charged me quite a...

I like the SR-71 sound wise and it doubles as my portable / home amp. However there's a question in my mind about the durability of the input / output jacks. As I run it both portable and home use, I keep plug and unplug the cables and cans almost everyday... will the jacks become loosen pretty...

Hi all, just browsing the Ety site right now and read that ER-6i is a limited edition... Anyone knows how "limited" it is? Besides, are the tips of ER-6i the same as ER-6 or even ER-4x? I think that maybe my canal is a bit short, the tri-flange doesn't give perfect isolation and get loose...

I had placed the order for a SR-71 from Todd on 10-Sep and it arrived today (15-Sep)! I live in Hong Kong and am very appreciated with the quick response and shipping! Thanks man!

Hi all, I've read some posts about the mod pads. I'm interested in the quarter mod on comfy pad but I'm not sure how to do so... Is it that I just need to make a hole with a diameter of 1/4 inch in the middle of the pad? Thanks a lot!

Hi all! I love the look of the Tivoli... but I really know nothing about the sound of it. Anyone owns it or tried it before? Besides, for just a little bucks more, I can get the Cambridge Audio 540C... I'm quite torn between these 2 CDP... please advise~
