Loud and clear!
 Naturally, just about everything else in the song is louder but definitely audible to a good degree. My pads are semi-flattened, this might affect the seal.

Meanwhile my head is pretty big too but I'm almost at the lowest setting on the sliders... I am using my own headband though, which might be a little longer than the original headband. Just a little longer.

I don't know about the comfort, only by feel because i didn't actually use them on anything ( they aren't mine ) BUT they do seem like they would be worthwhile. Not hard by any means.

 

 

Where's Vaughn and his update on the excellent looking salad bowl T50RP project?  Does he like it, or does he not? Enquiring minds...

Recently I got hold of a Yamaha HP-1 and applied some damping. Although I liked what I heard I soon set out to put the drivers into a wood housing. Now, this is the result. I am using two layers of felt behind the driver plus (one of them has a hole of about 1.5cm diameter), held in place by a disc of medium density foam. I also lined the cup walls and bottom with with some acoustic foam. The pleather pads were taken from a cheap computer headset. They fit perfectly.

so, how's the bass?

From my experiments on an HP-50a I concluded that it's easy to over-dampend them, and as a result you end up with a major decrease in bass.

Bass is plentiful. As a result I had to use a second felt disc!

Nice work. How does it sound? an improvement over the stock in your opinion?

I  would say so. Yet, I have learned to hold back a little and give myself more time to evaluate and make changes/tweaks with respect ot damping and stuff before I jump to conclusions. I would not want to praise something just because I made it and want it to sound fabulous.

Applying changes in the damping scheme is a lot easier compared to the stock enclosing though. I first tried the shells open back (too muddy), with a closed vent (too thin and congested) and finally settled with an open vent. To my ears there is still too much bass that way, so I am experimenting with partly closing or damping the vent with foam/felt too. It can easily be accomplished from outside. My ears seem to tell me that an additional foam stopper in the vent reducing the airflow sounds best.

Stratocaster, if you had to guess at the frequency response curve in the lower midrange and bass, would you say there's a broad peak (we call it a "hump") somewhere (compared to midrange level) in the bass? if so, where would you say it is?  Or would you say the response rises as you go lower in frequency and finally hits a mechanical cutoff way down around 20 Hz or so?  Or is the treble slowly rolled off, but starting around 1 or 2 kHz, giving the impression of too much bass?

post #20245 of 24682

To me they sound really flat from the cloud region down. At normal listening levels I can hear them go down to ~17Hz. The second felt disk (the one without the hole) recessed the highs, so I took it out again. I am really happy with these now. Really significant treble rolloff starts after 10KHz

Are you happy with treble after modification? Do you find the amount of highs right where you want it? How would you describe the sound of these headphones bright or dark? And the most important do you get fatigue with listening after mods?

Looking good, stratocaster. Funny, I usually find the opposite is true in regards to muddiness in open vs. closed backs.

 

The ebay pads arrived yesterday so I tried putting them on the AT-702 but the circumference is much smaller and there is no way they would stretch that far. My solution was to rip off the fabric/foam connected to the adapters and just glue the pads onto the adapters. Works fine. And as expected, the bass is absolutely massive now, even after I added a layer of thick felt damping. This is the same thick felt that I bought from the batch BMF had, that was all the rage way back when.

Good weekend for Yamaha orthos here in small Northern Europe country.

 

Finally found a guy selling a vintage Electone who still had the HP-50A for it. He didn't seem willing to sell the phones separately (= cheaply), but it turned out someone else on that auction site was selling a pair of HP-50S for a reasonable-ish price, which I took. I've never seen a single Yamaha ortho on there, and to have two on the same weekend is neat to say the least.

"Lambskin pads? No thanks, I'll have the duct tape ones."

As everyone, I've had longtime problems with the HOK pads. These 'new' pads were originally like this (not my image; Philips SBC 3150), but I cut them to roughly fit the HOK baffle, taped the seam shut and the pads onto the baffle. I've had negative experiences of the durability (lack of) of duct tape on pleather surfaces, but one day I'll get around to actually buying pads that fit the HOK.

 

The comfort is good despite looks and the sound is ok; I'll see about getting some frequency measurements later to see the relative change vs. the original pads.

The wood HP-1's are definitely dark sounding headphones. The higher frequencies are laid-back, they are not fatiguing.
