Hello everyone. I have been an RS1i owner for about two months now. Before that, I owned a set of 225i's...
The RS1s were very disappointing out of the box, compared to a pair of well used 225s. The sound of the RS1s changed dramatially over the course of the first 10 hours or so, and then settled in.
Well, I thought all the break in was pretty much over with then. And yes, for the last couple months they sounded the same. That is, until the last few days. I have noticed that the sound has 'opened up', if you will. Wider staging, and the treble seems to have smoothed out to a degree, and albums that at one time sounded a bit harsh and fatiguing seem smoother and much more listenable.
Then it hit me. Based on my listening patterns, I am right at about the 200 hour mark. I believe I have read that the Grado's need 200 hours of break in. That does indeed seem to be the case.
All I can say about these headphones now is extremely positive. They still have that forward upper mid bite that is characteristic of the brand, but gosh, they sound sweet.
Anyway, if you are considering these cans, or if you have recently purchased a new pair, give them time. With some patience, you will be rewarded with a stellar performer.
As far as my associated equipment, I am using an iFi iDSD nano powered by the iUSB....
Back to listening!
ps... i am quite willing to consider that this is all in my head. One reason why I think this may be an actual phenomenon is that I wasn't looking or listening for any changes. I have just been listening as always, and noted something new. Only then did I even think about break in...
