I don't know what you mean, my source is a cowon j3, my iems are gr07, and the volume, i don't know. Never measured dB levels before. That's why i asked people who own the same playback set. If you need any more data let me know. Thanks :)

Hi, i do notice the difference in isolation of my iems vs earbuds, they rock at semiquiet places where i can feel all the detail at very low volume(6 to 8). In the train, even though they isolate quite a lot, i loose much detail, whisperings being very hard to hear I wonder how much volume would...

I read at some places by some people that there's controversy about burn in, some argue that it's just a myth. i never checked by myself but anyway i like how they sound right now so no big deal. if it improves great if not, i still like it very much. regards

Yeah i guess thats the way iems are. I cant ask the feel of closed cup headphones to a pair of iems. Still i cant complain i wanted isolation to give my ears a break after years of loud playback to kill the noise in the streets, and to listen without disturbing my classmates. I got both plus a...

Hi, i just received these new iems, and they sound great. Then i thought, let's see how they compare to my old cheap $20 sony earbuds (MDR E819V) and my denon dh-1001 over the ear headphones. I liked my denons better. I just like that little extra reverberance the closed earcups provide, it...

Hi, i just ordered the iem's. I know the j3 is a mighty little player, but i wonder how will it deal with the 62Ω gr07 without any extra help. I've already spent quite a LOT with the j3 + gr07, so the only reason i would purchase it is if it gives some noticeable benefit. And worse than the...

Hi! Thanks for the quick response!. I understand that you get no sound leakage with a good fit and insertion, and you already checked it with some friends, but then you say it's a hard one to call and you want to test it right now. So i'm a little confused, what's to be tested that you didn't...

Hi, i'm considering one of these so i can listen to music at quiet places like my college's library. I'm really not supposed to leak any sound, any kind of noise is really frowned upon. Of course i'm not gonna max out the volume, i appreciate my eardrums, but i'm afraid some frequency range...

I stand myself corrected, the technical support from my retailer said this is a normal thing. He spoke with a cowon representative and confirmed it checking it with another J3 in the store. And yeah, probably i mixed up korean with hebrew hehe. Sorry. I could delete the post but i rather leave...

Hi. I just received a J3 player from a cowon online reseller in my country. I'm totally pissed off because as soon as i started it, the default language was Hebrew. I doubt very much that's the default langauge they preset in Korea. It should be either Korean or English or Spanish (Spain). To...

Hi again, after an intense week of research i made up my mind. I wear earbuds in the street, but because i can't afford a good IEM right now, i'm considering using my denon ah-d1001 out of home. They are just 32 ohm, so i guess an external amp isn't actually needed, right? I couldn't afford a...

Hi. I'm most interested in a high capacity model. Obviously X7 comes mighty in this aspect. What concerns me is, i'm quite an active person. I use to bike, jump, run,... and i'm fairly concerned with damaging the hdd if i'm listening to music while doing this. Even jumps in the playback would be...

Edited. Changed my mind.
