2) I read that the quality of the music I use during burn in is also important, does 192 bit is enough or I should use 320, flac etc.  ? and how about using something like soundcloud? 

No to both. burn in is basically mechanical wear induced to the driver to reach optimal condition for sound reproduction (as is for car engines). so it doesn't really matter if you burn in with high or low quality music, as long as it encompasses wide frequency range and is loud enough. I use noises and frequency swipes in a looped mix... set the volume on higher level - one that you wouldn't dare to listen to... :D

why is it important to let it play 2-3 days straight ? does it really matter ?

from what I see you guys contradict each other a bit, or maybe i just misunderstood.. for the sake of my understanding :P let say I usually hear in 75% volume  hence i should burn in 80-85% ?

I can't comment on the bitrate though. For me, I used Adobe audition to create my burn-in file and put it on loop for the entire duration. Maybe someone else can comment on the bitrate?

 

 

For conclusion  I will just create a playlist with pink noise inside and my favorite songs and to make sure it cover both high and lows I can use Electro for lows and bass and Adele or something for highs and vocals? sounds good ? 
 
I got the feeling I over think this hole burn in thing.. thanks for your patience :)

well, we do contradict bt no one said it's bad :D for me personally, I find that higher volumes do the job better. you need to swing the diaphragm a bit stronger so that it will set in faster. it basically moves up and down and everything that works with that principle must be worked near their limit for it to have a proper effect. if you hear distortion, just lower the volume. I'm not 100% but for car engines, it is recommended that you rev them all the way up so the wear is even for the whole working length of the pistons. I have no reason to doubt that the same applies to drivers. there is a risk of damaging the drivers of course but the sound will distort much earlier until something bad happens.  I've burned in all my iems with that method and every omne of them works ideally :)

All i can say is that the volume is a contentious issue. Some recommend maxing the volume, some say louder than usual, some will say that the usual volume is fine. Personally I don't think there's much of a difference except for the stress levels you are placing on the drivers. I will say that slightly louder than usual will be good as long as the drivers get some exercise, but not too loud till they die on you.

 

For the number of hours, it is recommended to burn the thing in for at least 200 hours. But the recommendation given above is to let the thing run in 2-3 days so that you can get a better impression of it when you put them on as they can get a little sibilant out of the box.

 

Finally, for the type of noise to use. I will recommend white noise since they produce every single frequency at a fixed strength. They should be more than sufficient for burning in. I made a 6 minute track (5 minutes of white noise and 1 minute of silence) to be played on loop for the entire 2 days.

Volume level can vary from device to device, or if you are using a separate amp.  There appears to be more of a mechanical burn in with biocellulose drivers, or at least it is perceived that way anyway, and I always say about 50-75 hours at least because that is when I began to notice little changes when I had my BE.  Most of the actual 'burn-in' will be you adapting to the new sound signature really, so it's not like you can't listen at all when you first take them out of the box, but just keep that in mind.  Even now, if I switch between IEMs it takes a few minutes to get readjusted to the signature.  It's not so much 'mechanical wear' like in a car engine, but it's still similar.  Biocellulose material is super strong, so if there is any actual physical change it's minimal.  Whether I'm crazy or not, the treble did smooth out a bit and the bass did tighten up...again, could just be perceived just by listening.  

 

Also another thing to point out for those that experience sibilance or harshness in the treble, insertion depth does help out a bit in this regard.  Deeper insertion I've found makes a difference, as well as tip type, but it's likely going to be hard for some because the nozzle is fairly short.

Try out as many of the provided tips as possible to see which works best for you!

As far as i see everybody have a different opinion on the subject, I have read that white noise is a big no no very dangerous and doesn't worth the risk, I am starting to get the feeling its doesn't really doesn't matter how you do it - just do it, preferably with pink noise or music for 200 hours.. 

 

 

is there a guide or something that will help me understand those graph here ? :\

Source doesn't matter and quality doesn't matter; it's just about playing the drivers through. But just use pink noise for burn in bevause IMO most effective and white/ brown noise can damage drivers if used in an improper manner.

Unfortunately after about 4 months of moderate use, there seems to be something wrong with the right earpiece of my gr07 BE. Sound does come out but it is a bit muffled and noticeably softer in comparison to the left earpiece. It was fairly easy to notice after a couple months of use, it sounded like nothing was coming out of the right earpiece but after removing the left it was clear it was too soft. Has anyone experienced this with the gr07s? or other IEM's? I bought them through mp4nation, any trouble with dealing with them? I verified before I purchased them that they were an authorized vsonic dealer, at least they told me they were.

Stupid question, but have you cleaned out the filter on the headphone?  Sometimes if you get a small piece of wax or something in it, it can muffle it like that.  Pull the tip off and see if you have something in there.  (hopefully you haven't already done that and it's as simple as that...tho not likely).

I was hoping it would be because of that but I clean them regularly, when i checked that day they were fairly clean, nothing more than usual before I clean them.

MP4 is a legit dealer for VSONIC like FiiO and other brands,so no worries. And if you have done all your basic first level inspections urself then your next resort is to contact MP4.


Open up a support ticket and wait for their instructions(RMA#,where to send etc).The shipping cost to company for service is our part. They are good responding tickets. But, in an unlikely event, If you don't get response in time, contact Raz. not sure if they entertain to have it replaced with your local VSONIC dealer,if your city/country have. as the dealer has to abide with VSONIC's policy.

 

http://www.mp4nation.net//contacts  (the best support system,ticketing, than Toll free #,emails)

 

a point to note:they might be busy on CM,x-mas deal orderings and processing so slight delay is kinda unavoidable.

Thanks a lot, I'm going to wait until the BF/CM craze ends and then contact them.

Has anyone ever compared these to the Monster Gratitude in ears?
