Any idea what year these RS-1 are?

You're going to have to post a picture for people to identify it. The RS1s have been in production for some ti me.

There are some tell tale that should provide some indication:

1. The cable pass through on the bottom of the metal ring is cut away as a circle not an square notch as Grado has been doing for the last 8 years or so.

2. The box and the use of the blue/green foam.

3. The bottom side of the headband has a bit of padding, this has not been the case for quite a few years.

These look like a "classic b" model, check out the thread on dating the RS-1.

Thanks for the information, I will take good care of these.

Count yourself lucky, your cans have a unique non-replicable identity and a history (:

Congratulations on the vintage goodness and welcome to the Grado club

These are vintageB RS1 that came out around the beginning of 1999. Are the drivers pink?

They came with pizza box so it seems unlikely to be a vintage RS1, it should come with the wooden box

Their headband is black so it is not the earliest version of the vintage RS1 (the earliest is brown headband

but the sound is the same)

Please show us the picture of the driver whether it's pink or not?  some vitage black headband may come

with pizza box or no box if they don't keep it well enough but the pink driver will have more mellow sound than other

and is of high demand.

Your RS1 had button at the back of driver so it should be at least semivintage, however the detail of the

driver will tell you what version of semivintage is.  Even semivintage RS1 have different version with the "Late

Friday" is the least desirable.

Is you cable the original one, if it is it should have the letter JG (Joe Grado) at Y splitter which can be clearly

seen  than the other part.   Please show us the photo of the Y splitter.  It can help confirm the authenticity of the

vintage or semivinatage RS1

If you get the semivintage Grado RS1 you are lucky to have the price of 425$ with the condition that you showed

including the box, I hope they also provide different earpad or 1/4" to 1/8" adapter too.  If that 's the case you

are very lucky.  You can sell this on head-fi 525-550$    or if you have the pink driver too it may go up much higher.

All RS1 had the wooden box and outer thin cardboard box before this point. The supplier of the wooden box went out of business after 9/11. Check the following thread for details:

The vintageB RS1 I have do not sound as good as the older versions but are nevertheless very rare.

I have to correct the information about the letter at the Y splitter.  All my Grado's which include the PS1 had the letter

GL   only the HP1/HP1000 is the letter JG in a circle.  So if it is JG it can be certain but it is usually the letter GL.

The other persons who may know better (besides Joe Grado himself) is pcf who is right here and another one that

can have that experience is Larry Dale at headphile.com.  He knows almost everything about the Grado. please ask

him.   I think yours belong to the semivintage which is also highly aftersought but the price may not be as high as the

real vintage one with full accessories and wooden box, it may reach more than 1000$ for the vintage.

Here is another reference that you should take a look:
