hd25-1 appreciation thread - Page 164

post #2446 of 2455

Just did the uber mod on my cans and have to say the improvements are remarkable and would encourage others to give it a shot as long as you got a steady hand.  I also did encounter the same issue as Jacob but managed to get a pretty solid fit anyways.  I would also suggest that people try the pads that the HD-25 aluminum edition uses and put them on the regular HD-25.

They are more comfortable than either of the stock pads and have a wonderfully balanced sound to them.  I also tried using a pair of red Yaxi pads because I also am running a red Oyaide HPC-25HD cable, but I found that they bloated the bass a bit too much and narrowed the sound stage.  Its a shame because they look really cool and are very comfortable.

 

 

One qualm I have with the Oyaide cable is that the right angle jack doesn't have threads for a screw on 1/4" adapter which befuddles me since the regular steel cable has one.  I'm planning on either attaching a new right angle jack that has one or maybe trying one of these chinese cables from fleabay.

Just rejuvenated my 4 year-old pair of HD25s (+velour pads) with the uber mod and copper cable.

I agree that the most noticeable change is in the bass range. Immediate impressions were that the bass is lacking but you should soon notice that the bass is still there, albeit leaner and with better extension.

The mids do sound a touch further back than before, but it's not a huge change. The highs sound great - still forward but a little more polite than stock.

Overall the new sound is cleaner, airier and more balanced than before. It does lack a little energy compared to stock but OTOH it's less fatiguing for extended listening. Considering this was exactly what I wanted to achieve from modding them, I am pleased as punch smily_headphones1.gif

Hi, which copper cable did you buy to use with the hd25? And if you swap back the stock cable is there still an improvement in sound just by dampening & loading the hd25 cups? i.e. Is it worthwhile doing the uber mod without cable upgrade?

I got a 1.5m OFC cable from CustomCans.co.uk. The improvement over the stock steel cable is subtle but audible. It cleans up the sound somewhat and makes the HD25s sound a touch more detailed than before.

The mass loading and damping still accounts for most of the improvement, though. I'd say it's definitely worth doing even without a cable upgrade.

Ive come back to some hd25s,one of the reasons i got rid of them last time was the brain chrushing clamp, triportsad.gif So after looking through this thread here's a few pics of of my freshly modded hd25 with sp headband, most people who do this mod turn the cups upside down so the cables are equal and bottom entry like the sp, they also normally upgrade the cable to the hd600/650 type cable but you loose the protection of the cable clamp on the std hd25, seeing as the connection joints are notorious for being niggley I decided to keep the standard routing which helps stop the connections getting tugged and keeps the steel lined cable which is more durable and I personally don't think I would notice any sound upgrade.

I just cut a groove in the sp headband foam with a Stanley knife roughly the size of the cable and stuck a foam strip from the amperior headband over the top, you could use the normal hd25 pleather strips there cheaper, but because I am going to use the velour cups( which also makes them more comfortable) I thought it looks better having the velour type material, I was going to use superglue to keep the cable in place but it seems fine and this way it's totally reversible without damage and I still have the normal headband and cable if I want to swap back.

I think it's much more comfortable and the sp band makes them even lighter, its really easy to stretch if you still think it has to much clamp,I have heated it with a hair dryer while clamped over some books, it seems to have a lot less memory then the standard band and now the cups are not together when of my head like in the pictures.





I admit the cables are a bit flappy,as it seems to be a shorter path then the original but i don't think it will be a problem, I nearly used super glue to hold them in position but again I don't want to anything to permanent, I think a couple of small black elastic bands will do the job perfectly.

Thanks for the link.

I was wondering if there was some way to adapt circum-aural pads to the hd-25-1 II.

Glass wearers like me would appreciate the comfort.

Another option :

Just out of curiousity. Is it normal to have the right channel just a tidge bit louder than the left?

 

On my e18, turning the dial to the lowest settings, I can hear just a smidge of sound coming from the right cup. I suspect that it has something to do with the right channel being a shorter cable.

 

But all in all, it's only audible if I spend all my attention on this, and it becomes invisible once I turn the volume to normal listening volumes.

It is normal and not your headphones causing it. Amplifiers using potentiometer volume dials are common with low volume imbalance.

Got my HD25 Aluminium leatherette pads in the post today and replaced the old velour pads on my Uber modded HD25s.

I bought them because I found that while the damping mod on the inside of the cups does tighten up the bass it also makes the low end sound a bit lean at times, particularly when out and about in noisy environments. These new pads have beefed up the bass impact a little without detracting from the overall balance, which is great! 

 

On the downside they aren't as comfortable as the velours, but then I suppose that's to be expected. I think I might try the Amperior velours next as they seem like they might be a happy medium between the comfort of the HD25 velours and the improved bass from the leather pads.
