I bought these back in 2006 and these have a serial number of 3xxx. No box. Comes with original Grado 6.35mm to 3.5mm adapter. I don't have the 3m extension cable any more.

The pads are NOT Grado originals and I just bought these pads a couple of months ago.

Selling because I hardly ever use these. I used to spend a lot on headphone setups and I've sold almost everything since early 2010s. These have been sitting in my wardrobe doing nothing until a few years ago when I bought a Fiio E10k to go with these (I just wanted a cheap USB DAC).

MUST READ: after a few years of owning these in 2006, one of the sides suddenly would give out a random hissing sound over a certain volumn very occasionally. This symptom has now disappeared and I have not heard the hissing sound after I picked the headphones up a couple of years ago. I have no guarantee if the problem will reappear. When the problem used to appear, I was using a Singlepower tube amp.

Pick up is from Auckland. I am not looking at shipping these at the moment.
