Initial impressions on the sound : A real joy to listen, warm and pleasant. The highs are a tad subdued but not so much that it detracts from the music. I'd say these are KSC75 in openness without the harshness in the highs and WITH the bloom of the px100s. It'll put a smile on your face.

Needs a fairly good source. My fuze sounds pretty damn good and vinyl too. Inferior sources sound dull and congested. Great value all in all.
I'm glad you like them. For their price I think they are an exceptional pair of phones, and pretty comfortable too. Now if only I could find a way to open them up and recable them...

2 points for me...

Pull the headband off of the cups. Very easy to do...just like with grado. Twist the cups apart. Voila!! Recable or otherwise tinker to your heart's delight. You don't even need to remove the ear cushions.

I'd take pictures but my camera sucks and I'm sure you can take a look for yourself with 15 seconds of effort

I immediately notice that there is a felt covering the rear slits from the inside and that this foam does not allow much air to pass. Upon removing the felt you see that only the middle slit is open. There is plastic between the slits and felt for the two side slits. There is not much air movement going on in here at all...but still a little bit.

The driver is definitely glued into the housing. The clips that were being seen are for holding the driver into the housing as it is inserted from the back side of the baffle board. Looks like the clipped it in and then glued it. Oh well...

Now I'll wait for you guys to figure out how to rein in that bass just a tad and we'll have some very nice budget cans here.

PS -- These will not be displacing my sextetts. Nope. but perhaps the D1001. We'll see. Can't speak for sr80 but the sr225 didn't even see them when it ran them over.

OK. Remove felt from slits = BASS MONSTER...not in a good way.

Make them completely closed = has potential. easy to try by taping them up from the outside.

I'm going to try adding some damping.

do these cans seal outside noise as well as the AKG K81dj? How do they compare to a Tac-modded K81dj sound wise? I imagine better...

Denser felt on the vents should do the trick. And maybe a cheap SPC recable. That's what I'm going to try on mines as soon as they get back from Tony who has had them on loan for a while.

I preferred them to the SPC-recabled SR-80 I had. Granted, the SR-80 had awful pads, but still...

OK. Dynamat on the backs of the cups and recabled with mogami 2893. Only the middle slit is open because I already figured out that it was enough. There is no felt on it, its just wide open. Added some polyfill around the sides of the driver as well.

Bass is tamed some, maybe too much?

Removed the part of my poly donut that is right near the vent. That helps. The right amount of boom and punch. Can't A/B but it seems not to be spilling into the mids now and I thought it was before. I'm done for now.

Wanna buy some d1001's? I already found them a kinda boring but reasonably competent and their comfort was a big plus. These Yamahas sound much better to me. Punchier bass, very nice mids. Gets me moving with the music. Very nice indeed. I'm gonna have to put 'em against my sextetts now. Wow!! $40 shipped for these!! a little tweak hera and there. Yeehaw. I may actually be DONE looking for portable cans that make me happy.

Great!! Well done for finding out how to open them and trying some modding.
These are definately a superb bargain buy, and if the mods make them better, then wow.

Im curious....why block the other two vents?...

Hah!

I knew they had potential, they are already nice in stock form, and now that you found out how to open them they could really be killer cans at a ridiculous price. Nice job!

Did I say these things smoke the d1001? Beats them up with a big f*#@#n' hammer.

I wish I had a stock pair now to compare them to. I may buy another pair anyway. I'm not sure I would have said so easily that the stock pair was preferable to the d1001. I have yet to really compare it to my other current cans.

They are doing justice to a lot of my favorite tunes. I am too buy trying to throw different stuff at them and they are just like, "Yea? What else ya got?". Steely Dan, Radiohead, Tool

Superb bargain? Fo' shizzle!

Any EU online store carrying these? In the US they are all around... I like a good bargain!

I remember the first headphones I ever bought, Yamaha HP-1s. They were so comfortable and sounded great; I wish I had never sold them. Yamaha replaced them with the YH-1s which looked the same, not sure what sound differences there were. Anyway, I'm looking for an inexpensive pair of headphones to use with my Luxman SQ-N100 as well as my iPod touch and will grab a pair of these. Amazon has them for $50 shipped which seems like a good deal to me.

Thanks ludoo for bringing these to everyone's attention.

Oh, and someone's earlier comment about many of the higher priced headphones having too much treble emphasis, I couldn't agree more. I bought the AKG K701s when they first came out due to all the rave reviews and even after 500+ hours of play running through a tube headphone amp, they were just too fatiguing. Sold them to a buddy who likes them a lot.

You can always buy a vintage HP-1 or YH-1. There's a whole thread on orthos. They've become somewhat popular.

Thanks for the suggestion and link, but I ordered the new Yamahas today...

Well I wrote another somewhat lengthy post and somehow it ain't here. Anyway...

Notes and such...

WARNiNG: Be careful with the stubs of the forks that hold the cups. I broke one off and have to superglue it back now and hope that works. Otherwise I'll have to go into serious engineering mode...

I tried removing the foam that is over the drivers, between them and my ears. This is not a good idea. I had no idea it would have such a dramatic effect. It turned into very honky, overly mid-rangey, yuckiness. I was not expecting much effect at all but what a surprise. The effect is SIGNIFICANT. I experimented and the foam didn't have to be right on the driver. It was fine sandwiched between my ears and the cushions...just as long as it was between my ear and the driver it was fine. Two questions on this: 1) Does anyone know where to get more foam that is like that stuff?? I'd like to have some extra on hand and wouldn't mind experimenting with it in various compositions and thicknesses and such and with other cans. 2) Does anyone else have experience with this phenomenon and other cans? I now have a theory on why this happened but I'm curious if it has been observed before. I had only previously read about effects on highs with this type of foam between an ear and a driver (both re: Senn HD650 and Ultrasone Pro 650 mods).

Sound is still good to me after immediate excitement is subsiding. Not fatiguing. Good bass slam, some to spare. A bit congested in low mids and into upper bass with busy music. Sometimes wish for more sparkle, upper extension. Both of those wishes come to mind primarily with poorer recordings. Good recordings tend to sound fine. These aren't perfect cans but I'll sound like a broken record and say again that they perform as well or better(IMO) than some others that get a lot more attention around here and cost considerably more.

I am going to make mine single entry and install a 3.5mm jack so I can swap interconnects. I am thinking that most of the time there will be a Sansa Clip riding on top of them. No wire hanging below my ears
