has any one heard this set of can's? they appear to my eye to be the same as superlux 681 and samson 850. Got a good price couldn't resist. seems the only diff from superlux is diff name on band and all the red rings are blue. found good photo here I've seen their 4 slot headphone amp a million and one times but have not seen nor heard of this incarnation of the same design. I keep thinking rebadge, but I recall reading some feel there is a difference between the 681 and 850. I will see how they compare.

Wow, I must try to have a discussion with Superlux to put my brand of headphones on the market. It will be HP2D4 ............ So you guys support, ok?

Just like the Samson is in fact made by Superlux. Judging things I suspect it's an HD681 with blue rings. It could be the HD681 inside but might as well be HD681B or HD681F depending on what Presonus has selected as 'their sound'. Only graphs and ears will tell. They talk about 'extended bass response' so it's most likely the HD681 The Samson and HD681 have different drivers and different sound. In sound the SR850 sounds more like the HD668B (less bass and treble and warmer mids) The SR850 is twice the price of an HD681 The HD7 is 3x the price of the HD681. Who is the smartest seller ?

Thanks for that info guys. I'd say PreSonus is the smartest seller, judging by that info. but I'm a smart buyer as well. I paid the same price for these HD7 as the 681's. well 4 dollars more actually that comes down to shipping and the fact I ordered 3 different cans when I ordered the 681's. I'm excited all the same, its been some time since I could buy something for myself [ who amoung us don't like getting new gear? ], thank goodness xmas season is upon us. makes it easier dealing with 'the boss' first thing I'll be doing is checking out the drivers see if they are the same as 681 or 668B, those are my only points of reference, as I don't have the samsons. I guess what surprised me the most is that these HD7's are out there yet I don't recall seeing anyone mention them on here ever. time will tell what sort of beast they are. I can compare them to the stock 681's as the filter from them in Fran's box filter 2. btw frans I think I like the sound of filter 1 better than filter 2, filter 2 seems to take to much from top half of spectrum. what exactly need I do, to make it filter 1? I recall you said something needed changed just don't recall what? mind you if just listening to the filter 2 the music sounds good, but once I use the filter 1, that is when I see the difference between the two. the main thing I did not like was it actually changed the sound of the snare drum[filter 2] may sound silly but I know how drums sound intimately. at first I thought it was the way it was engineered, but alas its the filter changing it. and here is another funny bit to my ears, the stock 681's I have don't bother me at all, except some sibilant sound < i think that is the right word , on certain recording. makes me wonder if there is somehow a difference between the stock on these two sides of the world? assemble in different place? anywho, I'll post up pic's and thoughts on the HD7 in due time. Peace

Changing the filter just takes the changing of 2 resistors. Since my hearing is still pretty good for my age I don't need much treble lift and like the 2nd filter better. You can change the resistors to lower values and increase the treble again. Even an in between or just slightly less then the filter one.
There simply is spread between these cans. There is between most cans really.
PM me for details.

Where do you buy the PreSonus HD7 headphones at? Lowest I can find is $59 I purchased them on e-baay. it was a best offer purchase, if you have used ebay u know what I mean. bartering basically. one clue the 681 was my bargaining chip . not sure to be honest if the powers that be here in the Grotto, frown of price discussion. forgive me my brain is slow hope that helps you. as i had a hard time finding any good price, or for that matter stocked by the places I looked. Presonus page itself not well designed, I seen only small blurb in a kit the have them in. not even its own page. odd. anywho. I look to ebay for lots of things, have used it for years. my akg k701's, senn hd-650's and cardas cable,and also my X-CAN v3 were ebay purchases along with several portable amps. happy hunting Peace

HD7's have landed. feeding them ATM. which leads me to a question do those .... erm sorry lost term for them ... do 'noise' recordings work better than giving the cans different music to break them in? or faster for that matter? first few things I noted about the HD7 as compared to the 681 or the 668B for that matter. first thing was the left right plastic labels the L and R weren't as raised on the HD7. the cable is different from both superlux can's, more supple feeling, more rubbery and pliable comes to mind in the case of the HD7. it's the same with the headband as with the cable. next I took the pads off to see what I could see. I took a few photos not sure if the differences I seen can be discerned from said photos. but the gist of what I noticed different is as u look at the circle the big ring with the hash marks is different 681 is dull and almost a blue steel look, slightly blue-ish grey. the HD7 is a bit more silver, and shiny. that's what I noticed just looking at them, well the the obvious blue color instead of red I warmed up the v3, and was a bit surprised by what I thought I heard. [ did a bit of back and forth with the stock 681] to my ears, the HD7 out of the box had more .... um REAL bass, that which comes from the bass drum kick petal and the bass guitar, even synthesized bass. the 681's bass felt like it had some fat and flubber in it. is colored the right word? puffed up and bloated. and because of this more real sounding bass [ to my ears ] there was better separation between the drum and bass guitar with the HD7. The bass notes just ... again proper terms I don't know, all I can do is try to explain as best I can so anyone can understand .the bass notes just feel more real, not loose to where they seem to mush together like it does on the 681. which leads me to my next pondering. which superlux can is the HD7 most like?. hummm. 681? 668? the drivers all appear [mostly] the same. except as I noted above. I'd love to see the freq response curve for this HD7, to see how they have "tuned" them. while the HD7 is 32 ohm , as is the 681 it does not sound the same in the bass department. now I'm sure there are some scratching their heads thinking how can this be different.... same thing different label. I have to reference the 681 and its superlux info, they actually had shown three different "tunings" for it. stock 681 then and F and B version ... tuning... 681 boosted bass, 681F flat as they could get it I'd guess, and 681B tuned to have a balance as its signature. so its hard to say what presonus has decided to market. but I'm digging it so far. in the pdf notes of 681 and 668B the differences are 681 says "dome type neodymium driver" 668B says "double dome type neodymium driver". someone in the know can explain this one? also 681 is 32 ohm .25% harmonic distortion, 668 is 56 ohm and .3% harmonic distortion. perhaps like a 668B with better base. something I had be longing after quite awhile now. as i have always felt the 668B to have a better middle to top, half of the spectrum as compared to the 681. going to leave it at that for now, will report back after more burn in Peace

It could very well be an HD681-B. This also explains the pricepoint which is slightly higher on the B and F version. The B version one only differs in the real deep bass.
681 and 668B are totally different drivers and sound very different too. especially in the mids and highs.
If it sounds like the HD681 with slightly less (= more tight) bass it is most likely the HD681-B

If it sounds like the HD681 with slightly less (= more tight) bass it is most likely the HD681-B funny i just edit post to add the stock F and B tunings , if that is what they are called. anywho. I need more time to listen, but up to this point in not so many hours time into them I like it better than stock 681. I hope it stays the way it is or even improves cause I am digging the bass. my bass comments may have not be said correctly. the HD7 does not have less bass. I'd say it actually has more, my point was that it is presented in a more real way, it has better impact , yes it low, but its more clear. I don't know how else to say it. how about this the bass rumble is all real bass rumble? I'm sure there are a few that can explain what I mean. one more example of better base I draw from mid 80's when I seen Pink Floyd down under in the land of oz. long story short the sound was just as loud if not louder than other bands I'd seen, but their sound was just so real, clean, pure if you will. ... that single concert actually ruined the pleasure I would get from the sound of groups I had seen in concert since. PinK Floyd stood above all, and to this day I've never heard anyone that pleased my ears more.

the B version has the same amount of bass down to 50 Hz (which is already LOW) Below the 50 Hz the HD681 still goes up in volume while the B version slowly gets less till 20Hz. So the B version will not be sounding as having less bass but because it is damped more in the very low end it will sound more tight. Also the bass on some HD681's changes a lot in the first few hours.
In the end the Samson and Presonus (and God knows what else) are just Superluxes... rebranded and other colo(u)r schemes

In the end the Samson and Presonus (and God knows what else) are just Superluxes... rebranded and other colo(u)r schemes that is what I was trying to get at , at called it 'tuning' , so tuning, color. that is why I'd like to see a graph on it [HD7]. anywho. color , filters, and such have been on my mind since I got the presonus. I will add more on colors and filters on down the road, don't think its right to go into that too deeply, wanna run them in awhile and chk in on them now and then. I do have some initial thoughts but will hold them for the time being, cept this when your only listening to one pair of headphones you can be , I guess fooled into thinking they are very good, until you here a different headphone, one that does something better. all cans differ I feel , be it good low , mid, top, and we all hear things differently to a degree.

when your only listening to one pair of headphones you can be , I guess fooled into thinking they are very good, until you here a different headphone, one that does something better. all cans differ I feel , be it good low , mid, top, and we all hear things differently to a degree. Absolutely right. When listening to just one headphone you get 'used' to it and forgive it's flaws. Most people state the headphones are 'breaking in' but the fact is your head is 'tuning in'. Not saying can's don't have a break-in period, they do, some more then others. Just not so long as most like us to believe. That's what Robert tried to convey. I guess I should be buying a HD681-B version after all. Stuffing the HD681 with the right amount of wool turns an HD681 into the B version but can only verify this thesis by buying one. I like the colo(u)r scheme better (grey instead of blue). The F version is not for me. This is more suited for AKG and ATH-AD fans and will be too 'boring' for my personal taste.

I've been doing a bit of playing around and comparing cans. I know some will say I'm nuts but the HD7 sounds better to me than the 681 (stock that is ) .. again its the bass, its tighter and deeper. with a bit of eq work to my ears the HD7 has almost the bass of the modded 681. but the mids and high end are better than the modded 681. that's right I said it. I'm seriously considering taking the rings caps of the modded 681 and use them On the HD7. I'm feeling rather certain with that change the HD7 will be better. a few words on filter. version 1 is better, version 2 just robs too much of the mid, high sounds. it sounds to coin a phrase used much talking about the HD650, it sounds veiled. using AIMP2 media player it has 18 band EQ. once I set the EQ like this I'd say 80% of the music files I played sounds very nice. and centainly no more ... sry cant spell this one... simbellence, than the fully modded 681. flat EQ except for 4.0 KHz [-1.8 db], 6.0 KHz [-5.7 db], 8.0 KHz [-6.6 db], 10.0 KHz [-1.8 db]like I said for 80% of tracks this EQ adjustment works wonders to my ears. the other 20% , that lack a bit a bass, I raise up the 5 lowest bands. and bingo... I'm interested for others to try these EQ settings with UNfiltered HD7's or 681's. I'd like to hear from those that try this. mind u this is not set in stone, u adjust EQ any way u like, but after much mucking about, I found this to be a very solid starting point. you can adjust to your liking but start here. yes I'm nuts and yes I believe what I said. try it yourself. so recap, better mids and highs then modded 681, and only slightly less bass impact then modded 681, I will attribute this to Micks rigns and caps, for it sounds to my ears the filters take from the top half of spectrum enough for your brain to be fooled into thinking there is more bass, when in fact there is not, its simply the top being muffled. love me... hate me , I care not. I have to say exactly what I feel. straight up. If I would have never come upon the HD7 and played around with EQ my ears would have been perfectly content with the modded 681. I'll retouch on something I said before, we get content with what we have and you don't know that there is something missing from your music until you find something else that sounds better. case in point my first serious headphones were the senn HD650, I loved loved loved them, then I heard the mids and highs of the AKG K701 and it made me realize the senns were "veiling" the real sound. very similar eureka moment with current situation. Peace , MaN227

There are also sonic differences in HD681's amongst themselves. Mostly in bass quality and amount and the treble part. They are about the cheapest good sounding cans that exist you can't expect there is no spread amongst the production which is probably is mass quantities.
about the filter... version 1 is not 'better' then version 2. In fact when you are young you would prefer version 2 over version 1.. that simple. Also in the accompanying user manual I encourage people to experiment with the values of the resistors to suit to ones taste. As clearly stated in the filter desriptions the second version is more in the direction of the HD650 the first version only takes away the harshness. If you want inbetween simply replace 2 resistors and tune it to your ears. Its like saying the AKG K701 IS better then HD650 (or whatever). It is NOT... it's different... you like it more... personal thing both have qualities owners prefer as all owners hear different and have different preferences.
There is NO perfect can but for person there is... they are simply not the same cans.
As you correctly state: we get content with what we have and you don't know that there is something missing from your music until you find something else that sounds better. That's the essence ... but it remains a personal thing and is not the absolute truth for all.
the eq values are essentially what you get when using the first filter type (almost exactly within 1 dB).
Take the top of your filter box and replace the appropriate resistors and use the (first type) filter for the HD7

Take the top of your filter box and replace the appropriate resistors and use the (first type) filter for the HD7 are you kidding me? that's bizarre. where exactly does it differ? cause I just chked again, and flatten EQ [to use modded 681 ] and everything up top still sounds better with the HD7, high hat , cymbols , snare for that matter. . they are less recessed, not grainy or bothersome just more there. , I don't know how to explain it other than to say it that way. guitar is the same story. and it touches some vocal as well. to my ears its a clear diff between them. [i.e. not a subtle diff where u have to convince yourself your hearing it, its a clear difference. seems there has to be more different than 1 db, in what band is it u say it differs?
maybe there is a reason this can sells for more? perhaps they got the best drivers? better matched? just wondering as u say the 681 itself can sound different.
from having the 668B and 681 stock and filtered, and the presonus HD7. the simplest way to say it , its like having 681 lows and the mid highs of the 668B. sort of a best of both worlds.
I will contact you via PM on the filter changes, Frans
surely I can't be the only one that has the HD7's, I very much like to hear the thoughts of those that have them and try the EQ settings given.
the more time goes by and hearing the same things. I seriously thinking to use my one set of Mick's rings/caps on the presonus instead of the superlux. they are DEFFO getting the AKG velo's.

Ahhh... that explains a lot as you heard these instruments up close and louder then all other instrumentalists. This explains why you like the top end of cans to be 'lifted'. You FOCUS on these aspects. Either caused by ear damage due to excessive SPL or because you focus on it.
the HD7 does not have the HD681 driver but probably a (selected or not) HD681-B driver which is sonically slightly different also in the highs acc to the graphs. As an experiment you could buy the HD681-B as well, you'll prefer it over the HD681. It has grey rings instead of blue. I expect the -B version to be very similar to HD7 if not the same.
The first filter needs to take about 7 dB off to take off the 'edge' but still sound 'detailed'. the second edition takes off more so it looks more like HD650 in highs presentation which is a bit too 'little' for a (former) drummer.
There is nice in-betweens to be had filter wise.
You can even install 2 small pots and adjust the filter solely by ear (is what I did to start off from)

very interesting points. and you know, you bring something up.... I have seen the .... ermmm... plain 681 then an F and B version of them according to superlux info, but I have not seen or heard of anyone having an F or B version of the 681. why the Fruck you think that is? anyone either heard or own an F or B version? will PM you more about the filter. I'm not so sure its being closer to the drums as much as it is knowing what they actually sound like, intimately so. usually the most fiddled with thing is the snare drum again i'm gonna throw this out Joe Satriani - Black Swans and Wormhole Wizards fantastic album, I'd guess the musical might say it has very good production values. everything recorded sounds spot on to my ears. such awesome balance. something often not happening when such a talent with the Gee[Tarr , with the head swells the volume u know it... I've listened to this album quite a lot since I acquired the FLAC files. awesome bass player and drummer as well to be sure. They are the first thing I noticed, tight , baby, tight, everything has its place, very good instrument separation. I just can't say enough about it and the thing that tickles me to no end is how well miked the drum kit is, and this may sound crazy to some that can't hear the difference, high hat and each cymbol has its own placement in my head. they aren't all mushed together. brilliant now, this is gonna seem real bizarre but I have never seen Joe or his band play, and if i'm correct from what I hear, I'd say there is a fair chance the drummer is a lefty ;D what are you waiting for give it a listen
