Sennheiser HD 555 to HD 595 Mod :)

Postby Hammer_Time » Mon Oct 29, 2012 12:23 am

Just modded my own Sennheiser HD 555 headphones to HD 595 by simply removing the foam strips covering the inside of the vent holes:

http://mikebeauchamp.com/misc/sennheise ... d-595-mod/

What are the differences?

Aside from the aesthetic differences, the only physical difference was an additional piece of foam inside the cheaper HD555 headphones, blocking about 50% of the outside-facing vents. Since both the HD 555 and HD 595 are designed to be “open” headphones, reducing the vent with this foam would alter the frequency response slightly. So to save yourself $150, open your HD 555?s up and remove the foam. Done.

How to do the mod

The foam cushions are removed simply by pulling on them. From there, use a screwdriver to remove the driver assembly. Once open, remove the black foam stuck onto the back of the outside-facing vents and put everything back together. While you have the foam cushions off, it’s a good time to give them a cleaning (damp cloth).

Is that it?

Yes. The actual sound difference is very slight, but it is noticeable. My guess is that the foam is there only to slightly alter the frequency response of the headphones so that the two models have their own “character” and response curve when tested (some web sites actually graph this as part of their reviews, such as headphone.com ). While both headphones sound good, the HD 595?s preserve their more desirable flatter frequency response curve. It’s this flatter frequency response curve that some people are willing to spend the extra money on, and Sennheiser know this.

Quite a few people speculated in my Original thread that the more expensive HD595 headphones must also be using a more expensive driver. However, Head-fi member MCC posted the smoking gun; a picture of the original Sennheiser replacement driver labelled “HD 555 / HD 595?.

Works great!! Very easy to do ( you need jeweller's kit tiny phillips screwdriver ) and I can hear a little bit more bass out of my cans now! No need to buy a headphone amplifier! 8) :lol:

Free upgrade to HD 595 cans!! 8) These are still selling for $350 on Amazon.com right now!! :

I paid $175 for my HD 555's, but they are only $112 on Amazon.com now!! :shock: :D Deal of the century!!

http://reviews.cnet.com/headphones/senn ... 22851.html

Just remove 2 strips of foam and you turn your $112 cans into $350 cans!! 8) :twisted:

Of course I would rather own these ( along with Asus new $1000 headphone amp of course! :wink: ) but can't cough up the $1600 for them:

:shock: Never would spend that much on headphones. The specs look WAY better on the hd 800 compared to the hd 449 (one I want, will accompany my electronic drumest :licks: :reading: ) but not 1500 bucks better :roll: :lol:

Btw the what I assume to be german companion site http://en-de.sennheiser.com vs the US site http://www.sennheiserusa.com/home looks WAAAY better imho. Just something I noticed :lol: :lol:

For that you get "The World's Finest Headphones" ( that might be stretching the truth a bit, there are other top-notch cans out there too, but cost similar outrageous amounts ).

Oh, just noticed that the HD 800's are going for $1500 now on Sennheiser's site! :D

I would only blow that much dough on some cans if I was uber-rich, but I am no Mitt Romney when it comes to my financial situation... :cry: :wink:

Ah, the HD 449's are a slightly lower end model than the 555/558 series, no ear surround reflector but 449 does have an extendable cord which is cool... the 558's ( $180 ) replace the older model 555 ( only $112 on Amazon.com right now!! ) , but the 555 can be modded easily into 595's. Not sure if the 558 can be modded to 595 but most likely the answer is yes. 555 is the best value/bargain right now till they sell out completely...

Yes, the German Sennheiser site does look WAY better than their American site. Probably cuz Sennheiser is a German company, so that makes sense that their "home" site is the best one... Americans get a "dumbed down" version, which sadly probably works better for most Americans! :wink: :twisted: :lol: :whistle:

The question is ... can you mod the pads to be vinyl like the 449 instead of it being cloth. I sweat alot and I will most likely be sweating up a storm if and when I play drums. I like metal WAAY to much :whistle: :lol: thus the cloth pads of ALL the other medium to high end closed ear phones headphones sennheiser makes could get gross pretty quickly.

Ha ha! I sweat a lot too while gaming with my cans on!!

Dunno about vinyl pads, I guess you could buy some vinyl ( naugahyde etc. ) and cut them to shape, then glue them on over the existing foam pads... not sure... an upholstery expert could probably do this for you for a reasonable fee methinks...

I actually prefer the softer foam pads, even thought they get nasty, they are easy to pop off... then you "hand wash them" , put a drop of laundry detergent on your finger then rub it into the pads...get them wet first of course... then rinse them off and put them in the sun and they are usually dry in an hour or two, or use a hairdryer to dry them faster... then you have nice, clean, sweet-smelling foam pads afterwards!!! :scout: :D

Won't vinyl pads cause more sweating?

Yes, but you can easily spray sanitizer on vinyl or fake leather/naugahyde and wipe them with a cloth and they are good to go ( no sweat stink after ).

With foam pads, once they get soaked with sweat a few times, they get all rank and smelly like gym clothes... :P So its more work to have to manually clean foam pads with soap and dry them out after...but I find foam ( with cloth cover ) much more comfortable of course...prefer foam.

$175 purchase itself feels a lot to me, heck even anything more than $50. the last time i spent big on sound was when i bought Motorola S9 about 7 years ago. they were well worth it given my past purchases were wired headphones $20-30 which in 6 months or so broke due to wiring. I lent my S9 to my brother who managed to do it in after few months of use. I have since used wired Samsung headphones which were awesome but they too now have gone bad due to wiring. So I am in the market to buy a set of headphones.

i am looking to get in-ear headphones. I like the bluetooth wireless ones simply because the stretching of the wire is not an issue, however, having to charge every now and then is not something i like. i listen to music during my daily 5k jog, at work and at home watching movie on my laptop (sometimes sharing one earbud with my wife) or video chat. So have plenty of need for headphones that don't require charging in between these activities. This leads to me lean towards wired version.

I like something like Samsung HS3000 which has both bluetooth and wired solution. If the battery is dead then disconnect the wire and connect directly. regardless i feel i ought to buy both this and a wired version to keep it handy.

what wired headset from US would one suggest that goes for around $15-30max w/ S&H.

PS. sorry for hijacking the thread :twisted:

I didn't have any luck getting in-ear ones to work while jogging. A little bit of sweat and they kept falling out. You may just want a cheepo pair for that. I like the Sony MDR-E10LP. Cheep, comfortable and stayed in fairly well. You could then plug them into your H3000.

Yep, those Sony earbuds are pretty amazing for only $10 !!

I don't think you will find anything better under $30 out there...

Can't use earbuds, after a short while they get uncomfortable.

These won't fall out of the ear, but are double Stupe's budget:

i need the ones that have a rubber stub for in-canal. the rest in-ear headphones just come off easily from my ears.

the ones HT just linked to would be supported by the ear but again won't stay on properly thus losing sound level and quality.

I tried running with these ones:
http://www.amazon.com/Sony-MDR-EX81LP-B ... B0007N55LE
and they still just slip out. I'm not sure any "in ear" type would work for me, but maybe the nubs you mention would help.
