How do you like these JVC headphones? I just bought a JVC 4VR-5406 receiver for a desktop system. I thought some matching quad headphones might be good, instead of a speaker array. Is 7 wpc x 4 sufficient? I have some Toshiba HR-40s.

I'm guessing that would be enough power for the headphones. I'd be interested it hearing about the sound quality of those headphones.

My Toshiba HR-40s sound good with JVC 4VR-5406. Plenty of power. I'm not a good judge of headphone fidelity though.

I just got a pair of these a few days ago(first pair of quadphones for me), they are nice and shiny work like new. Some odd things I notice are when listening to the sq/as output of my receiver it seems to more balanced with the phase reversed on one side, left on some recordings and right on others. Another thing I've noticed is when listening to a stereo recording through a headphone splitter(double stereo) with both sides in phase reverse, it seems to isolate the vocals and cancel out the background music(kind of neat, it highlights directional sounds), if you pull out either of the plugs the cancelled out sound will return.

The user manual explains (with a degree of hyperbole!)-

That hits the nail on the head. Mine didn't come with the manual and I didn't think to download it yet. thanks!

I now have two pairs of these. Unfortunately one of the drivers/speakers is blown in the first pair and is very difficult to replace if you could even find something to replace it with. That being said I really like these phones, they sound good and the drivers are spaced horizontally and so do provide some front to back separation. Many of the Koss phones place the drivers vertically which is almost useless for providing any kind of surround effect. The phase switch is part of what Koss also does with the Phase 2+2's, The phase idea originally came from the "Fixler Effect" headphones.

So you have opened these before? I've read that the drivers are 1.5 in which is 38.1mm, most replacement drivers are 40mm. Do you think there is room for 40mm? I dont want to open mine su de they are still working but it would be nice if they went as loud as my Sony MDRV6 which have 40mm.

Actually they measure 50 mm. The diaphragm itself would be 40 mm, but they have a metal ring around the outside and they are held in place by four rivets. I wouldn't try to replace them unless they were damaged.
I recently repaired a set of Koss K/6LCO using drivers from AliExpress said to be for Sony MDR models. They actually sound good, not as much bass as the original Koss but cleaner mids and highs and about the same volume level.

I actually tried to open one side yesterday just to look but the screw was so tight it would probably have strip before coming loose, I'll have to search for a junk pair to attempt to modify.
