When I bought my RS1is, I had the good fortune of being at a dealer that had multiple pairs. There was Quite a difference! I chose the brightest.

You might hear a difference between your two. Let us know, and enjoy it! You are Lucky! (I have an RS1i AND and RS1 with no plan to depart from either).

 
Well, I might put them on sale or trade, so it's better if I keep them new.

How is this that Grado's can go "pop" all of a sudden... I'm terrified.

any headphone can blow a driver, for various reasons,

  Well, I am pleased to report that the box contained what was advertised.  Some on this thread rightly questioned whether my dear Santa Wife would instead commemorate my being naughty, not nice, and perhaps give me some of the well-deserved dirty socks I'd left lying around in the house by popping them into that box!
 
But... NOPE!  Grado PS1000s!  They are already broken in, have a brown leather Turbulent Labs headband sleeve, and the sound, with my HPA-1 amp and FiiO X3, is Breathtaking!
 

Spoiler: .

 

 
Initial listening on the lossless albums Jazz At The Pawnshop & Eric Clapton Unplugged takes the features of my very best Grados so far (RS1i and HP1000) and adds more:
 

1. Soundstage - I really AM amongst the instruments, and I can almost convince myself that the low notes on the left of the piano come from a different spot than the high notes on the right!
2. Bass - not at all lacking when I use Grado amps with the RS1i and HP1000, but these have MORE!
3. Microdetail - inner voices, little buzzes and clicks, some from string slap, some from fidgeting audience members (live recording), which are distributed across that larger soundstage.
4. Comfort - these are the first over-ear Grados that I have had, and though some complain about their weight, I find that I do not notice it, but much appreciate the pressure removed from my ears that the on-ear Grados apply.

 
Some have stated that the PS1000 is a headphone that will scale up indefinitely with better upstream equipment.  I can certainly believe that!
 
(Oh, and I've gone and picked up my socks!!!)
 
These headphones are FANTASTIC!

 

 
Wow...wives can be really nice (/ useful) from time to time (it seems)...

 
One lucky dog you are.

The easiest way to do it is to connect two leads to a car battery for a short moment of time.

Having your volume at 11 will have the same effect.

At normal listening levels it's near impossible to do so

DISCLAIMER: don't try to pop your headphones. This kills them. In a bad way.

i wonder what happened to mine then,no car battery, and listening at my usual moderate, to low level, strange.........

How long do you guys let your tubes warm up before starting to listen to your Grado hp's?

 

[whirlwind]

it seems the mad ear takes about 5-10 minutes....to sound its best....depending on what tube i use....but overall about 5-10 minurtes

Thanks 2dubs, for the 596/6SN7 tube combo on my WA6 it seems that twenty minutes is the minimum amount of warmup they require. Have a great Boxing Day!

I dont think it was anything you did, Jay.
 
Just one of those things that happen...like you said any headphone can have a driver go bad at anytime.
 
I can, however see how having you amp cranked when you turn it on could cause that to happen.....I really can't imagine too many people having their Grado's playing at that loud of a volume....especially when they are meant for lower volume listening.

Only thing i could think of is having your headphones plugged in when tunring on your amp.

A power peak could happen at that point...

I'm sure I don't need to mention it to you, but you know that you should always open your mouth while listening to headphones, right?
 
In that manner, you relieve the backpressure caused by the musical energy, thereby preventing the ponderomotive force from damaging the headphone drivers.
 
Physics teaches us this to be true, while art demonstrates it... you have never seen headphones go bad on a singer wearing them while performing, have you??
 
Q.E.D.
 

 

[bassboysam]

LD1+ owners, what is the warmest/smoothest tube you've used?  I keep coming back to the WE408A, everything else I have tried has made the amp way too bright and harsh, especially with Grados.  Just wondering if there is anything "better" than the 408s.

i'm good about not doing that, i was just listening away, amp had been on a while, strange, 
defect in the driver somehow ??

I usually let my tubes on the WA6 warm-up for 20-30 minutes also before listening, and if I don't I'll listen at very low volumes until they've warmed up. Woo claims it's fine to listen to the amp after 1 minute of warm up for the tubes.
