I've got the original box, manual and adapter.

Spotted a guy watching an iPad, using a set of Sennheiser hda 200's on the train in San Francisco. http://en-us.sennheiser.com/audiometers-high-frequency-testing-closed-dynamic-ear-protector-headphones-hda-200 They look pretty sweet.

My in-laws may be considered audiophiles and have some very decent equipment, as do I. I married into the Heil family, and now I own most of Oskar Heil's toys. That said, I really don't have the ears or knowledge to consider myself an audiophile.

I brought my ESS MARK-1's to the Head-fi meet up in Redwood City, CA last month and let 2 people give them a try. Then I got shy and left the place, since I'm not really an audiophile and didn't really know what to say to anyone. I just walked aimlessly around with my cans. Maybe, if I feel up...

If you can't get someone to do it, you can take BART to Milbrae, and then Caltrain to Redwood City. I don't know how far the walk would be, but I'd guess about a mile. 

Thanks! I was trying to figure out what I could bring to accompany the Mark-I's, as I usually just use an old ipod and a Radio Shack adapter, so I was looking through the basement, and came across the good Dr.'s Marantz CP230/CP430 Stereo Cassette Recorder. I have no idea if it works or not, as...

I'm not much of a convention guy, and don't have much of a headset collection, but since I could bike there, was born there, was married there, and may just die in Redwood City, I'll try to make it. Since my only decent headset has provenance, I'll bring it along with the original box and...

Yes it does. Tested it last night. It seems to think that it is there, and audio comes out, but mic does not work. Same setup worked fine on PS3. I'm tempted to buy another dongle (wish I could find the other Plantronics dongle that I know I own), and see if another works. I can't seem to find...

I'm using a Plantronics Gamecon 307, which is probably their low end wired gaming headset. Yes, mic cord goes directly to usb dongle (Dongle has a switch, and it is set at mic, instead of line, for whatever that's worth). Jumper cable still doesn't bring voice from usb into headset. I haven't...

NeoVinyl, I've got mine set up exactly like yours, but can't get my mic to work. :( I'm using a USB dongle by Griffin, made for compatibility with an iMac, which worked great for my PS3, but doesn't seem to work properly with my PS4. So far, only the PS4's earbud works for mic input for me...

Yep, played beta, played ps3 bf4 until last Thursday. Now I've got a new PS4 and play BF4 with a bunch of the guys from Reddit.http://www.reddit.com/r/bfvoip/ (subreddit for players that use in game VOIP, playing all forms of Battlefield). Some of the guys are on BF3 PS3, some on BF4 PS3, and a...

oops, see below. 

Check out my "review" http://www.head-fi.org/products/ess-mark-1-stereophones/reviews/9741, although I may not know what I am talking about, as I don't have any other headphones to compare them to, and I haven't listened to the Precide Ergo's in about 9-10 years, so I really can't compare. Maybe...

Pretty decent sound, although not enough bass. I just added them to the Head-fi database, under ESS Mark 1 Heil Air-Motion Transformer Stereophones ( I think that's the title, well at least it's the only set of ESS in the alphabetical listing) and I did an online audio test yesterday and posted...

I don't know how many of these are still in existence, but you sure can add that to your "want list". I spied what you "Have" and you may have an addiction, and there is nothing wrong with that. 

Plus, I'm new to this, so do I hit "Reply" or do I hit "Quote" and then "reply"? Man computers are hard (note: I'm an IT guy). 

  By this you mean that I am married to the grandaughter of a great contributor to audio engineering, and my current awesome audio setup. 

Silly, the original was posted in 2006, my daughter was born in 2008. 

Heil Tube, FET (Field-Effects Transistor), AMT (Air Motion Transformer), decent artist, furniture builder and a bazzillion other patents.     Oskar's Wiki http://en.wikipedia.org/wiki/Oskar_Heil

My daughter is about 3 years younger than yours, lives on the Peninsula, and is the great granddaughter of the great Dr. Oskar Heil. She shall inherit all of his vintage audio equipment and the stories behind them. Like her great granpappy's ESS Mark 1 cans, in original box from 1976.

I went to Lynbrook. Sang in choir and Jazz Choir, and was in two plays there. Grew up in Regency Park townhouses.
