HI-FI Choice, "The finest hi-fi magazine online", rates the JVC HA-DX3 (200 UK pounds) higher than the Senn 580 and the Grado 325.

Are they insane, or have we just overlooked the JVC because of brand name? Does anyone here own a pair of JVC cans?

JVC advertises the following specs:

50mm driver, neodymium magnets
Freq Resp: 4-30kHz

They tested the HD590 not the HD580. The Technics is also
the only one with a Best Buy rating. Go figure.....

 

[DesBen]

590, sorry. My bad.

As for the Technics, I decided not to include them, because of the huge price difference. Not the same ball game.

odeen had a pair of these that he sold awhile ago...you should get his opinion on them

 

[lini]

Well, I guess they should have taken the dead rats out of their ears, first. I read their review about the beyerdynamic DT531, and I disagree in almost every point. But, of course, they can savely write nonsense, as long as they don't tell what equipment and what music was used...

The HA-DX3's are really intimate for classical guitar, and chamber music.. Otherwise, they're not too hat. Dan Pumphrey's brother bought them from me, and he really likes them, he says they remind him of the CD1700's.

You know, for some reason i think those JVCs use the same Sony drive units as the CD1700. I have sneaking uspicion they do. They are remarlkable similar to look at ofr a start, and the sonic qualities are descibed very similar to my CD1700s. 500mm drive unit too.

they obviously care more about comfort than sound quality. it's a good thing they didn't try Etys! morons.

I never realized JVC made so many phones. They obviously take this seriously.

I would be surprised if those were the Sony 1700s. I doubt they'd OEM just one phone. Unless all those are sourced from someone else...

Where's our man, KR? He'll probably know.

I like how the JVC webpage calls those headphones "Digital Readiness Headphones"

 

[eeyssjr]

Well, once again the similarity with CD1700 are uncanny.

I mean, CD1700 says "Digital Reference Headphones" on them.

This just adds weight to my suspicion, that JVC use CD1700 drivers. They wanted to market the headphone in the same way as sony, so just changed it a little to "Readiness" - whatever the hell that is.

KR - help me out dude?

 

[Odeen]

The only thing is, the JVC's have a 90-ohm impendance, while the Sony's are 32, if I'm not mistaken.
So they may have _similar_ drivers, but not the same... And the only other headphones to use 50mm drivers, as far as I remember, are the higher-end Denons (750, 950, not sure about the 550)

Odeen: Can't cable changes effect impedance?

 

[Odeen]

They could have installed some extra resistors in the drivers... but running the CD1700's out of a 120-ohm output impendance jack on my amp doesn't really make it sound all that much better..

I'm not so sure?

If Sony has pioneered this Biocellulose driver technology, would they really be prepared to share it with rivals?

Yes, If JVC paid Sony loads of money for the patents and designs, then maybe, afterall money does make the world go round... BUT surely JVC would have to move tens of thousands of these things for the costing to be worthwhile?

These are my least spoken about 'phones (although they are listed in my profile)... I really didn't like them when I got them so have since given them to my dad... Bummer is, that at the moment I can't do any comparisons or anything because he's taken them on holiday with him... maybe when he gets back
