You must be listening to music at some pretty loud levels then for there to be that much leakage. The Alpha Dog hardly leaks unless you take the headphone off your head and wear them around your neck.

+1, I also really need to know if the Alpha leak much less than the TH900 or the LCD-XC.  My TH900 leak too much and I can't use in some silent environement without disturbing the close people.    
So what is the best choice for NON-Leaking top Headphone ?    Alpha Dog ? LCD-XC ? SigPRO ?......

 
I don't know how much they "leak" per se, but the Alpha Dog clamps fairly tightly to the head and like the Mad Dog, which I owned before, provides a seal that's a bit like a sonic vacuum. I can't imagine that there's any noticeable leakage at close range.
 
I've owned the TH900 too, so I know exactly what you mean when you say it leaks, and I think the Alpha Dog's isolation is much better (at the expense of soundstage, though).

  OK! I've read through all 253 pages of this thread! (I know sad huh), man it was a minefield and my eyes are bleeding. There are some nuggets of good info in there amongst PAGES of OT stuff.
 
So to aid those who are new to the thread and just want to read only the good stuff (no offense to anyone) I have created a summary with links to all the impressions and reviews including some vital information. In rough order of appearance except when grouping reviews from same person. Sorry if I missed anyone's reviews, it was a LOOOONG thread...
 
Enjoy!

Not necessarily the Fostex leaks a lot compared to most other closed as they are not sealed.
 
In a totally silent room while trying to sleep they will definitely bother light sleepers or people trying to relax.
 
In our office it is like a quiet library. My colleague is only about 2 meters away directly behind me. He can't understand any of the noise but it does annoy him the sound that he can hear.

I suggest you use the HE-500 so he can also enjoy the music.

LOL yes!

That's true for stock, but the ADs have been completely sealed. It's part of the mod.

FWIW, I always used my MDs next to my sleeping roommate with no problems at all, didn't test leakage with the ADs, but I doubt it's any worse.

Haha, by Fostex I mean the TH900! I was at first asking for comparisons for leak from the TH900/Alpha Dog

 
Thanks for all your replies though, seems like the Alpha would be a good option for the office to try out. Should purchase one in a few weeks.

The leakage on the AD is very minimal, even less so than the T50RP/Mad Dog.

Heard AD at the NYC meet yesterday driven by Liquid Gold with 2 sets of tubes (I prefer with small ones and Dan too) , portable setup and Shiit stack and compared to MD. I prefer MD only with Schiit stack but I think it's only because Lyr had stock tubes. Until version 3.2 MD had not enough bass for me but 3.2 has what I'm looking for but after trying AD at 2 meets with so many different setups I would get AD over MD. They have excellent comfort and isolation and don't feel heavy compared to HE-400/500 LCDs Abyss

I Heard the SigPro this WK and Liked it. Also i Liked the fact that it do NOT LEAK sound, so i Will be able to use it in bed when... My wife sleep. ( which is not possible with my TH900)

Question: does the ALPHA DOG leak more than the SigPro ? And what about the new Audeze XC closed version ?

When I ordered my Alpha Dogs at the end of August I hadn't seen Jude's video or read anything about them. It was some positive comments about the Mad Dogs that had taken me to the Mr Speakers website. I was after a good closed back headphone to pair with my forthcoming CEntrance HiFi-M8. Delivery on the Alpha Dogs indicated that I should have them about the time my HiFi-M8 was due to arrive. Dan shipped my Alpha Dogs just before he flew off to Japan for the Headphone Festival. The Alpha Dogs arrived last Monday.
 
I plugged the Alpha Dogs into HiFi-M8 using the same settings I'd been using with my HD600's and selected the last track I'd played on my iPod Classic, Dire Straits - Rome and Juliet. Initial impressions were of a quieter, leaner but quite detailed and spacious sound. Not quite what I was expecting and not much in way of bass. Okay, need to play something different, Nik Bärtsch's Ronin - Live, that'll tell me what these phones about.
Yep, that's more like it, we definitely have bass and it goes deep. A nice clear and spacious sound too. I played a few more things that left me with the feeling that the overall sound balance was a little light somewhere in the midrange but decided that might be due to the HiFi-M8 which was still quite new. I decided to continue listening on my main rig.
 
Moving to my main rig confirmed that what I was hearing was due mainly to the HiFi-M8 and not the Alpha Dogs. I found the Alpha Dogs very smooth and easy to listen to, fuller and more even sounding though perhaps not quite so spacious sounding as on the HiFi-M8. How did they compare to my other headphones? I only made a brief comparison to my LCD-2's but that was enough to convince me that two are quite different.
I think the Alpha Dogs are closer in character to my HD800's than they are the LCD-2's and they are perhaps closer still to my HD600's. Up until yesterday I'd have put the HD800's comfortably ahead of the Alpha Dogs along with the HD600's. The LCD-2's remaining something of a wild card.
 
Yesterday I swapped the Chord DAC that I usually use with my main headphone rig for my Metrum Octave Mk2. To put it simply the Alpha Dogs have amazing synergy with this DAC. Everything just sounds right with this combination.
 
What you hear with the Alpha Dogs is very dependant on what comes before them.

We've all spent much time comparing the AD's to headphones at the top of the heap, which speaks well of the ADs. I am really interested in comparisons down hill a ways. Say closed cans $600 down to $250 or so. I will go for the AD's, but since I like to keep my stuff in great condition, I'm also looking for a good pair of traveling and office cans down in the $250-ish range. I know I like the ADs, MDs. I also know I don't want on ears. If any of you out there have some comparisons and comments, please share, but please stay on topic with reference to the ADs. Note - pretty familiar wit the HD25-1-ii and the Beyer 1350's. Kinda done with those two.
