These are 2 very different headphones. If you are looking for something very fun and plan to listen to quite a bit of rock I would recommend the Grado's. If you plan to listen to everything else I would take the SRH-840's. But you should probably be looking at the sr-225 instead of the sr-80.

Do we know if the ps500's will be a permanent headphone or are they another limited edition? 

Looks really good. Is it a gloss? Or is it the same matte texture that the stock cans have?

I've not heard the Zune HD but the one thing I know is that finding a LOD is almost impossible to find. So if you ever decide to amp your headphones or use an external dac you will be extremely limited with the Zune HD.

It looks like Sennheiser HD-280 Pro on the top and I can't tell on the bottom. http://www.buy.com/retail/product.asp?sku=90051723&sellerid=29460652 They are going for $80 on Buy.com.

Check to see if any hair is stuck to the driver. That can definitely cause it to start buzzing.

So you're using the Rock EQ? There is no doubt in my mind you are causing your headphones to distort at the bass and treble frequencies. EQ'ing when done properly can yield some great results but will not make $50 dollar headphones sound like $500 headphones.

Koss UR-40's. I bought them from blockbuster and thought that they were the greatest headphones ever. I loved the bass and the comfort. I remember thinking 'man I really need to turn up my ipod to hear these! This must be what all the guys at head-fi are talking about needing an amp for headphones.'

Quote: Not that I agree with what the previous owner did but I can tell you that if you use the hd25 long enough the cables will loosen up and the sound will go in and out on one ear. All it takes to fix that is to simply push the cable back in until it has good contact. I am sure the...

You could also pick up the Monoprice Premium Hi-Fi DJ headphones. It seems like they are the exact same headphone and they will cost you less.

I listen to: 1. Rock (classical to hardcore) 2. Hip-Hop 3. Acoustic/Folk   I am located in Louisville, KY, USA.
