Hi!   Last week i purchased cheap, very old Stax system. It consists of Stax SR-80 electret earspeakers and SRD-4 adaptor.   Price was about 50$, so I was expecting something belonging more to museum expositions, than anything resembling HiFi behavior.   I was pleasantly surprised...

Hi! Some time ago, i tried APureSound mod, link here: http://apuresound.com/hdsennmod.html It's about 4 or 5 months now, now I have some time to write about how I perceived sound changes regarding the individual mods. Internal foam removal: resulted IMO in weird/bad look and, most...

Sorry, double post :-(

Hi!   I found some problem on an old pair of HD580.   When checking the rear side for loose drivers, i touched the damper  and it was not attached to the outer edge. The oval was about 90 degree (1/4) of the entire oval diameter detached from the plastic frame. Literally floating loosely...

Hi!   Could please anyone try swapping old (brass ring) drivers to the new metal white baffle? Or - putting new drivers into old (black plastic) baffle... This AFAIK, could help isolate what's cause for the change in perceived sound balance - OLD vs NEW Sennheisers 600 (and 650) threads...

Hi! For 2 years, I was using the HD-25 rather sporadically. In recent weeks, I was wearing them on regular basis. Here's the problem: the sliding ,ladder' is way too loose now, compared to new pair borrowed from my friend. It's so loos, after putting them on my head, both sides clik 3 or...

Hi folks! I bought the 414 yellow pads for my PX-100. I made a hole in the first pair of foams, diameter the same like the original hole. Reversed or not, the sound was lively, but not so smooth anymore, ut the soundstage gain and bass quantity taming was welcome addition. The second pair...

Hi! Last night I finally decided to remove the paper filter over driver's plastic screen. I had the idea for quite a long time, but was afraid I can destroy the voice coil wires, seemed so fragile... But i carefully pry opened the plastic web under the pads and phones were still singing...

Hi! I have the glossy black AKG in possesion for some time now. First listen discovered that the response is litlle tipped to the treble region and th bass was overpowering quite a bit. Immediacy, sparkle and sounstage seemed very nice. Detail and speed was aso above average IMHO. The...

Hi! I have the little Beyers for sone years now, having stuffed foam and wad inside cups, improving the sound quite a bit. But I still found them inferior to any real phones like HD-25 (much more expensive, I know). The bass lacks definition, is more gummy and the treble is quantity-wise...

Hi folks! Can someone help me with clue how to open cups of the HD-25? I'd like to try rotate the cups and there might be hair buzzing inside the driver. Thanks Moonwalker

Hi! Yesterday I did listening and measuring tests to my Sennheiser buds. I have older pair of MX-400 (4 years old) and newer MX-350 (1 year old). All listening was done on my old Sony MZ-R30 MiniDisc recorder, using headphone out and no added amp. The songs used were from Mike Oldfield...

Hi! After owning the MDR-F1 for more than 5 years, I was quite happy with them. The sound was extremely soft and non obtrusive for me and for casual listening or movie watching, nothing could be sweeter But one day, I found the headphonesguru website and I must say there's lot of truth in...

Hi! After long time, new post from me. Looking at the Headroom pages, I was unable to display harmonic distortion measurements for the AKG 701, nor the 601. Waiting long time, hoping it will be added, no such luck. Since nobody mentioned this, I really wanted to see that result. Did someone...

Hi! Here is the promised photo (3 pics taken), I'm sorry for blurry quality - it was evening and the exposure times were a bit too long for my not-so-steady hand For mods, seach for: moonwalker, hd201 The pictures are clear enough IMO, their names suggest what part I captured...

Hi! After many years of occasional use, I got the feeling the F1 must be wery well broken in. Now I know intimately their sound, and compared to my main speakers or hi-end Sennheisers, I came to generally known feeling their strenght is in the mids. Yes, they have deep bass, and high treble...

Hi! After owning 5 different MD machines from Sony (all portables) I came to feeling taht high-end models like MZ-R30 and MZ-R909 have flat/neutral output when the Mega Bass or EQ is disabled, but the MZ-E33, MZ-E60 and MZ-R500 have low or midbass hump about 5-6 dB even when all EQ is off...

Hi! As owner od Senheiser PX-100, I've found they leak significantly more than my old Koss Ksc-35. And I'm listening at fairly low or moderate volume. But on PX-100, the sound volume (and spectrum, to some extent) is the same on the front AND rear side of earcup. If I'm in some Grado...

Hi! I read the graphs on Headroom site, and while the FR graph seems pretty accurate, I was surprised to see that PX-200 (closed!) have such a low distortion like HD-650, where PX-100 (open, highly regarded model) has quite high harmonic distortions. For me, it was more surprising, because I...

Hi! Could you tell me if your cans have vented magnet systems? For example, my HD-600 and HD-650 have vented magnet (ring), and my MDR-F1 have it as well. I can literally see trought the driver magnet. I wanted to know if Beyerdynamic cans like open design DT-990 or semi-open DT-880 have this...

Hi! Owning the HD201 for awhile I'm looking for ways to improve them - they deserve a bit of tuning work IMHO to make them even better budget sealed cans. Any mods, comments are highly appreciated Thanx Moonwalker

Hi! Yesterday I tried (AND BOUGHT) HD-580. They sounded good enough to convince me (and my wife) to buy them. I opened them to see the driver type and was surprised there's only magnet without the typical HD-600's copper ring inside vent hole. Did you find the same? More on them later...

Hi! Few days ago, I bought and DISASSEMBLED the Senns HD201. More on that later, modding them just begun... I tried to increase bass extension and of course loked for damped/undamped space inside the earcups. BTW - their construction - very high standards - not material wise, byt nearly...

Hi! I'm using the Beyerdynamic 231 occasionally for some time, but I'm not fully satisfied with their sound. First time I auditioned them, in a shop using my trusty MZ-R30 Sony MD, i was surprised by 2 things: first, the clarity and extension of these phones seemed soo good. But, the mids -...

Hi to all Headfiers! After some time, i found my old Sennheiser MX400 and MX350 buds (both unmodded, foamed) somewhere in the draver, sitting, waiting for some future use. Using KSC-35 for more than year, every day, commuting, walking and shopping, I had to re-equalize my ear to the much less...
