post #21346 of 23654

tried recabling my ES7 SFI with an spc cable from btg so that my es7 would be more "blingy".. sad thing is that everything becomes thin. too much treble, vocals sound nasal, and bass becomes almost nonexistent and i think im hearing the bass at the back of my head. dang... waste of money hahah. unless im doing something wrong with the cables although i doubt it since everything went back to normal when i used the old cable =\

 

tried fixing the sound through damping and it doesnt help at all. small bass port on the baffle, bass port on the cups, some 2-3mm craft felt at the back of the cups, teased arctic cotton on top of the felt, nothing at the back of the driver. also covered the drivers with a thin felt and topped it with an accoustic paper that acts as a bass lens, hoping to reduce the treble and it only helped a bit =\

Sounds like you've done wrong there with your cable. Double-check everything and try again. If you fail again, try the opposite of what you did previously.

Okay so Project YH-3 gets into the swing here.

 

Replaced the pads with a simple medium density open cell foam donut 5mm thick and thus far the overbearing bass colouration has receded. This is now a much more balanced headphone if a little short on pounding bass (if thats your kind of thing).

 

 My question to the thread here is. Has anyone tried a circumaural pad system with the YH-3?

That would mean adding jumbo flat baffles somehow to the top , interesting idea.

Hmm I must have small ears:) The Circumference is pretty darn close to covering my ear so I was thinking about a memory foam "gasket" for lack of a better term with Velour pads over that. Considering stealing the mad dog idea of tapered pads thicker at the back thinner in front.

The case for channel balance convolution, as always.

 

Below, the channel balance (centered on 0 dB, deviation from that line equals imbalance) of the HP-50S whose both channels were modded in the exact same way. Orange is the channel balance without convolution, black is with convolution.

 

 

Below, CSDs (without the artificial ear) of - in order - the left channel, the right channel convolved, and the right channel without convolution.

 

 

 

 

 

 

Besides some extra chaff in the middle, the convolved right channel is identical to the left, while the unconvolved right channel is some ways off.

Okay continuing on in the never ending quest for YH-3 nirvanna.

By chance I ran into a baby carrier harness which consists of a velour type substance bonded to an open cell foam. So what the devil lets have a go at circumaural YH-3 MKI

 

Bad photo alert, low light no tripod.

 

 

 

This is the rough in with the two ends of the tubular strap held together with surgical tape. The cable points are being problematic here as they interfere with the pad seating. I am also not sure whether to slim them down or let them cover the whole cup. I plan on using silicone on the foam lining to make the join permanent and then a minimal amount of stitching on the outside to hold in place until dry. At that point I will try applying more clamping force around the cup/pad seal area to see what if any effect that has.

 

Sound is vastly improved and apparently  power consumption the opposite. Testing the poor little E11 to the max:) The drivers seem to like a slight cant of about 5 degrees. With the pads at this depth there is a lot of room to experiment with distance of driver to ear and so far about 4mm clearance is the optimal balance with regard to bass and mids. Highs are leaning into sibilance, but I think a decent filter over the driver can smooth that out. This setup does test the clamping force of the headband and that is something I will have to address. This will prove quite the test as they are just too comfortable with the minimum clamping being exerted now.

 

The goal here is to see how far we can get with just external mods. The cable issue is the wet blanket on this idea as there is no room around the entrance and the pad would have to be slotted.

Don't make anything permanent yet, imo. It sounds good now, but later on you'll A/B them with something and wish they had moar bass. Double stick tape works wonders for me with all those "tentatively finished" headphones where I may wanna pad roll in the future. Love the ingenuity so far, though. Props. Bet they sound real breezy.

Thanks. Not a big bass head here but they could use a wee bit more and that is where the clamping force comes into play. I am considering a thin aluminum re enforcement under the headband for a little more pressure.

 

 With a slighly embarrassed look on my face. The material used here was made to be velco adhesive. So shortly after the post I dug out the velcro strips I had thrown out after cutting the webbing from those pads and lo and behold we have a much better solution for the rough in than the surgical tape. It may even be a good enough solution for a permanent fix. That would allow leaving the cabling as is.

 

 The thing that I really love here is the comfort level. With that much surface area supporting the phones they just dissapear from your head after about 5 minutes listening.

 

I'd love to find a source for this material. As mentioned it is a velour type material bonded to foam with an internal membrane like tricot or something close to it. It must be a commercial product of some sort.

Err, the Tandberg ortho is available on German ebay, fixed price, a bit high, and quite worn. No connection, of course.
