Also my observation, (and this may just be perceptional), that the kind of music you are burning it with defines its sound signature when it opens up, may be the diaphragms are not fast  enough and tends to get hard wired with a signature. i dont know whats up with that, but i burned it with a...

well i would say about 70%

Yeah, I would say atleast 600 hrs. Me personally, I am at my 2nd yr of burning them in free time i dont listen to music. I wont compare them to a good open back but to be humble, they have a complety different sound sig now. its amazing!

Quote: I agree with the reviews. Its a really ambitious head phones, i imagine how the senior program engineers / architects must have presented on the white board a agressive project goal: open back, big sound stange, good instrument articulation, spacious sound stage, big bass without...

Quote: they will sound as good as a closed back headphone can open up. off course you can still not compare them to AKG 550, probably the most open sounding closed headphones with most open sound stage. but again, 550 dont have even have the chest thumping bass as crossfades. So its a trade...

Quote: Bro, I second every word you said. I have not seen any headphone change so much on a burn out. and strange thing is, the more you burn them out they just keep getting better. I came to a point (after like 500+ hrs of constant burn out with mid range centric music on high volumes ~...

I know this is embarrassing to ask and though my graduation major is in computer science and asymmetric algorithms, I should not be forgetting basic physics, but here it is:   How can we get the power required to drive the phones to a standard "loud" level, like 105 Db, given the sensitivity...

Quote: My god Are you talking about HD 800 when you said "No Detail to offer"! you should do homework duh! or have more listening time with HD 800

Quote: Having said that, I would love to have Sr325i in my inventory some day, Grado are really fun and bright headphones. and there are genres they put on me big smile. but still i am not sure investing in a 1000 $ GS 1000i is a good idea. i would go planer magnetic with that money. For...

Quote: All that analogy doesnt change the fact grado's are fun / thin / not accurate sounding headphones. And yes, btw I am only telling based on my ear, no graph i had seen before this.

Quote: exactly! I have a long face so they are just fine on my head!

Quote: Thanks smiguel! you have right to your opinion

Quote: Ok I Admit on more analysis 550 is better bang for bucks (as i just checked 2 min ago: 235 $ on amazon). closed headphone. with spacious open sound, little treble spikes on certain brightly recorded tracks, would need you to turn down your volume. but overall, advantage being, they...

Quote: well off course 550 sounds brighter! Also i think, and this is perceptional may be how i hear it, but 550 are also more sparkly then X1. Its all about what suits for your ears. There are people who simply love He-400, which i cannot tolerate for 10 seconds of listening. But I would...

Quote: I will step and and out of line here guys! most head-fiers on this forum, unless someone wants to correct me, have a nominal amp in their stack like E6 or something. Now these cans are 100db/1mW @ 30 Ohms. Even somerthing as Small as E6 can drive: Drive ability...
