This is Sonys first pair of digital headphones! In 1983 Sony company out did themselves with the best ever H-AIR pro monitor MDR-CD 5 headphones!  Some of the best sounding cans ever with 2-22,000 response!  I am very lucky to find this piece of history, complete with the box! 

Beauties. These look very high end. Great score.

Fantastic! Well done dbxS, and thanks for sharing those beauties with us!

Rare find well done .

 In the early eighties, this was one of the best pair of Sony headphones that you could buy!  Much like the MDR-5 and MDR-7 series of 1978,  you actually had the choice of paying a bit more for the same phones but a little better response.  So you could get the Sony MDR-CD7 and pay more, for the very best!   Then came the MDR-CD6, which was the next in the line.  These were the new best!   This new and improved version had a smother look and design, along with a bit better response of 2-26,000 Hz!  I  actually like the fact that I was able to score the box!  It is the ultimate display item for these rare cans!

Super super super rare! Great find.

Pretty nice to see the quality of packaging and how today's packaging still has some similar styling features.

Those are really nice.  I really love this site, so much great things to look at!

Had a pair in the 80's, one of the best portables I've owned until this day. I also had a few pairs of the CD-6 which came out a little later. Congrats dbxS!

I just found the manual for this!  I still cant believe how feather light these are!

Hi, 

Sorry to resurrect this post, but can you describe the sound? Is it warm, natural, how are the lows/mids/highs?
Thanks in advance

These phones have a great blend of highs, and lows. The lows are not overpowering super bass, a lot of the lows are achieved from the ear cup, air tight connection.  The highs are crisp, without being too bright.  The perfect blend for a man of all seasons, and all that crap, and so on...

Excellent find, Dean!

Didn't see this thread but those headphones look very good, and having them in such good condition, boxed, is simply great. Well done!

Can someone help telling me the thickness of the foams in cm or in inches? Thanks in advance

Hi NOFAREWILL, you can order replacement foams through taobao though they're a little awkward on the CD6.

Thanks!  Though I thought I might fabricate some foams from raw or make-up foam material, that's why I asked to know exactly what thickness I need for some diy work

Do you own these btw on the pictures?

These are the auction photos for the pads, mine are long gone unfortunately.

Do you think these are fir for the M88? Because I have some news: after a relatively long wait and countless search: and the ridiculous fact is that I cannot find any technical info on the net.  If you have any infos, pleasea advise

And one more thing, can you send the taobao link? I cannot find anything there... thanks
