Hi DecentLevi,   I have a feeling, after fixing my prior mistake, that my moded headphone is not that much different from yours (other than bass port).  I tried Lyova's, although it is still moded differently form yours, and I still like my original better.  Maybe it's different head and/or...

Small update:   I think I resolved one problem of my moded headphone.  I think when I put back my left driver is rotated 180 degrees and also there are 2 tab on my head phone to close the holder inside my cup is detached (thanks to packdemon notice this).  After I changed these, the moded...

Hi DecentLevi,   I bought the receiver for hometheater before I gotten into headphone.  Didn't realize that it has a pretty good dac+headphone amp section until I tried idsd micro and e18.  I was a little disappointed that $500 idsd micro doesn't produce the same quality of sound.  Well...

Hi Lyova,   I use silicon seal on the driver lips and close the cup as in your 1st photo before silicon seal drys.  I didn't need to use much as it is in gel form and does not over run much over the lip.  Inner cup ring is the same as in your picture (butyl) and is pushed in as much as...

Hi DecentLevi,   I am using Denon 4520ci and a USB drive as I find this setup to be better than my idsd micro and better than e18 from a laptop (foobar w/ wasapi).  I have 2 HP150s so I can compare them side-by-side.  One mod and one original.  If you have a suggestion for a small DAC+Amp...

Installed the mod according to the video a few days ago, here are what I think:   With original ear pad and closed base ports: Base and openness(3D) are gone.  Mid is now very forward but feels dry (I am not sure this is correct word to use).  Anyhow, I do not like from what I hear.   With...

Hi Lyova,   For the 1st graph, it looks like there is no change to frequency response with 75Ohms adapter.  Is the volume carefully matched between measurement?  It seems lines are on top of each other.   Colors are hard to see but from what I can guess, it looks like a good improvement with...

Ordered the mod kit from Etsy last night for my hp150, and see this latest post.   Great to hear hp150 response to the mod better than hp100.  From what I read, the mod is exactly the same between hp150 and 1st revision mod of hp100, right?    For the impedance adapter, is it just measuring...

Unit #3 left post office yesterday to next person in line.

Here is my impression of unit 3:   Out of all the closed head phones that I have heard (M50x, 280pro, 380pro, hp150, 553pro, srh940, M2,dj100pro,MPC), PM3 is most neutral and slightly boring when playing it straight without any EQ.  Sound is warm & slightly muffled. Bass and treble are both...

What's your impression after a few days of break in HD380? 

IMO, buying momentum 2.0 is paying for the style, design, comfort, lightness and portability.  Momentum 2.0's vocal is more accurate than HD280.  Due to cutting off some upper frequencies, Momentum 2.0 is much more enjoyable to poor recording than HD280.  HD280 shows more higher frequency...

I checked Guitar center's website and it seems that all those headphone are not available in store around my area.... I'll check San Mateo store... I am not getting my hope up though....    Is there another store you would recommend for SF Bayarea for try out headphones?

I like Sennheiser HD280 PRO more than M50x and Momentum 2.0.   HD280 has lighter bass and less fatiguing treble.  It has less detail than M50x but has more detail than Momentum 2.0 and more 3D/stereo.  The vocal is colder but forward sounding.  The biggest problem for me is comfort... but there...

Thanks JK1 & Panzerkiller13.  I'll try out HD380...  I read that HD380 sounds different from HD280 and some prefers HD280 especially due to weird treble emphasis and recess.   Do you have the same impression when you compare 380 to 280?   By the way, I thought Guitar center no longer let...

Sennheiser HD280 PRO is my favorite headphone.  By no mean that I feel HD280 is perfect.  I need some help in finding my next headphone--- an upgrade from HD280 PRO:   What do I listen to: vocals, modern/classic rock/pop, Japanese/Asian pop, classical, alternative Currently listen from Denon...

DecentLevi,  Shure 940 will be an interest for me.  Since I am just starting with this hobby, I am not 100% sure what I'll like.  I have been playing EQ with my 2 headphones and seems l like a bright/neutral phone even though my ear can get fatigue.  I'll appreciate it if you do bring it.  Thanks!

Got permission from wife and I'll be able to attend for a few hours.   My interest in headphone just started a few months back.  I purchased my 1st phone, Philips X2, a few months back.  It's sonic signature isn't what I like and I realize closed phone is more useful for me.  It sets off my...

I am interested in attending.  Please sign me up.
