One of my pair of GH1's are 4L and 4R and the other is (I think) 38L and 38R. Ironically, the 38's are the pair I purchased first and the 4's are the second pair.

Same here. I had a pair with protruding drivers last year and I sold them about trying to burn them in for better frequency response. No joy. Off to eBay they went. 

After about 50 hours of burn-in the top end above 4k (ride cymbals, etc...) has opened up nicely in the RS1e. They sound considerably better with the G-cushions. They are not as bright as the GH1's, but really really nice. The mids have cleaned up some, but are not as clear and transparent as...

Music. I use a variety of styles of music. 

update. I tried the G cushions on the RS1e's with my desktop setup (jriver media center playing flacs,bifrost uber and an asgard 2) and my better setup (oppo 105D, MAD Ear + HD playing the same flacs from an external hard drive). The G cushions take away some of the congested mids I've been...

I have about 30 hours on mine and the mids are starting to smooth out. They are still somewhat congested and not as much definition as I would like, but they are progressing. I looking forward to hearing them with another 20 or 30 hours on them. I'm pleased with the progression so far.

Thanks!

Mumbles06,   Would you mind sharing the first #'s in your serial number? Mine is 334xx. If you've already posted, my apologies. Are the drivers flush?   Thanks.

My PS1000e's were pretty darn good out of the box and have improved a lot over the past year. I have around 100 hours on them. They are a little more balanced than the GH1's with more mid-range, but still great clarity. The bass isn't as deep as the GH1, but it has improved since I bought them...

  Now see, you have me very hopeful...    I played an assortment of stuff through the RS1e's over night (about 15 hours worth) at a quiet volume through my Aasgard (on "high output) with the volume about 8 o'clock. That's the volume I use for my PS1000's. Anyway, I can hear an improvement in...

So, initial impression is they are all midrange and very little bottom end or top end. Almost a crunchy sound. I have 60 days to return them, so I'll run through 30 - 40 hours of music over the next week and see how they progress. The GH1's sounded great out of the box. These don't. They also...

I agree. I hear very few similarities between the PS500e and the GH1. I had a pair of PS500e's for the past year and recently sold them after comparing them to my GH1's. To my ears the PS500e's have a muddy midrange with reduced highs and accentuated low end whereas the GH1's have very clear...

I am really looking forward to hearing the new RS1's. My enthusiasm is definitely tempered by my previous experience but I am hopeful. It was my first Grado headphone and when i realized it stunk, I sold it and almost didn't buy another Grado headphone. In my typical "go big or go home" fashion...

It's my favorite Grado headphone so I bought one for the office that I also use when traveling. I keep the first pair I bought a couple months ago at home. I try to hide it because my wife loves it and has tried to swipe it! Lol

Dangit... I hate it when I get curious and bored... It always costs me money and when it's around you folks it tends to be a lot of money. I just ordered a pair of new RS1e's from Crutchfield. They have a 60 day return policy, so if I don't like them pretty quick they are going back. My...

Thanks for asking that question. I'm curious about the same thing.

          yes, sir. mine protrude from the wood housing. Mine have red drivers and were purchased in June 2015 new.

Mine had a 33xxx serial number.

I'm curious as to serial numbers on the RS-1e's that have the recessed or correctly placed drivers in the cup with proper frequency response. I bought one in March of 2015 with extended drivers and no bass and terrible trebles. I sold it in June of 2015. Terrible sounding thing.   - David

Thanks guys! Any thoughts on comparing the GH-1 to the RS2e?

I received my pair of GH-1's about 2 weeks ago. Really, really nice headphones. Joseph, yes, I have tried the G cups with the GH-1's and they are exactly as you mentioned. Thanks for the recommendation!   I have compared the GH-1's with my PS-500e's, RS-1's (with buttons) and my PS-1000e's...

You all are costing me too much dang money... MAD Ear + HD arrived today. MH - I upgraded the 12AX7 as you advised to a Sylvania black plate triple mica. More output and a punchier sound with the PS1000e's. This little thing really makes the PS1000e's really get up and boogie. The RS1's sound...

Thanks for the link. I'll check them out. 

Worms, may I ask where you found the case? Is it deep enough for the RS1's without squashing the cushions? The case I bought from the grado folks for my PS500e's is too thin for the RS1's.   Thanks, David

I bought the other pair from LPGear at the beginning of July. When I contacted them and asked if the RS1's were new or used, so they sent photos and they were the real deal. I was skeptical until I received them, but they were indeed NOS. stacker45, if you received the better looking pair then...
