I bought my first Grado headphone sometime between 2000 and 2002. I don't have the original paperwork. They have no letters after the numbers on the button (SR225) and the text is silver paint on black plastic. They came with the L-cups out of the box, not the flat creased version I see in stock...

Lets prioritize my help:   1) Noise goes away 2) Long wear comfort 3) Durability 3) Acoustics   My end game goal, would be to hypothetically have the sound deadening isolation to perform surgery at a death metal concert.

My work requires intense concentration, and I need to essentially remove the world for both sanity and distraction reasons. I usually use monotone speeches, classical, edm, or trance like music to drown out the outside world, however recently my work environment has gotten extremely noisy from...

  I hope you don't mind me questioning your answers.  The Pro2900 is going for $600, and the HE-4 is $900, putting them well out my reach.  Has there been a sudden surge in pricing on these models, or am I just shopping in the wrong places (is there a good online shop)?  Also, how are their...

I have several questions, please help.   I really need some help here.  My 10 year old Grado 225's have developed a static noise problem in the left ear when I move around the the cable brushes against me.  I suspect a problem with the cables (but not sure).  1) I don't know if my...

holy crap that's a lot of brands, any idea on how to start paring that down a bit? 

I'm creating this thread to help me identify various headphones I see from old videos.      Thoughts?

Koor, I never thought this thread would last so long.  There sure are a lot of Grado fans that have a lot to get off their chests.  I'm beginning to think that this thread might out last the heat death of the universe.  I can see it now, God on Judgement day calling out for any Grado fans to...

What do ya'll mean by 'inefficiency' in headphones?  I don't really understand electricity beyond the very basics.  Something I hope to change, but regardless.  I keep getting confused between the terms.    Do planar speakers/cans need lots of amperage? Are they low or high impedance and...

This thread has taken a life of its own.  Thank you all so much for your various contributions. 

Edit: Talked with my father again, he clarified for me that stereo speakers play by different rules than headphones.   Quote:  

So, I've been doing some preliminary research and its conflicting with what I'm reading here. Need some help understanding planar headphones. Background - my father used to do speaker installations and when I asked him about planar magnet headphones/speakers he said that the diaphragm doesn't...

Take ya'lls rap crap and anti rap crap outta here.  This thread be about Grado's yo.  Besides, I'm pretty sure real rap died with the Sugar Hill Gang. 

The EWS9 are listed as portables.  They sound like what I'm looking for, but I was wondering if they have a full-sized version?  Do they have a similar (or identical) non-portable version? 

Well those are some interesting wave patterns but I have no clue as to their meaning.    Question for ya'll, though I hate 'jacking my own thread here.  But I was recommended a Dennon D5000 with a KICAS amp and Jmoney leather ear pads.    So since there isn't a sound store anywhere near...

Quote: Please keep things calm.  "I" was the one that bought my cans ten years ago.  I only asked what happened in the intervening years.  

Quote: Well I don't need that much hand holding.  Its taken me 10 years of enjoying my 225's for me to decide that my taste in music sufficiently changed to want something that does a bit more and better.  I went from 70's / 80's rock and disco tracks to remixes of the genres in...

I purchased my Grado 225's almost 10 years ago.  Back then, everyone I knew were talking about grado vs sennheiser headsets and those that were made of money talked about Stax and thousand dollar or more amps.  Now, I hardly see anyone talk about Grado's headsets for anything except the cheap...

Need help picking a really nice set of headphone - full size.  I do not care about open or closed.  I need to keep total cost of ownership at/under $1000 (cans and amp).  I do not game.  I listen to a wide range of music and I need a headphone can reproduce a good sound-stage and still be able...
