My relative and i buy the bijou at the same times but I had burn in 80hr while he too busy with his work, and just burn in arround 24 hr only. He and i are really curious how far the performance than burn in longer time vs less time. I told him to try himself to figure out because only the ear can tell u the true. what the forumer give might be fake . This is what i get the quality after the burn in.
Here is the review on 24hr burn in bijou vs 80hr burn in bijou
I just use the Sony k880i hp as a player and use the convertor to play the songs. Various of songs had been listen, and most of them is Jay chou and Jolin songs. after all, the comparison of both bijou is very obvious. Both of us agree with the final results. The 24hr burn in bijou seems less details, less punchy, soundstage a bit blur..the 80hr bijou just like put the ward in the bijou and all the details become clear and all the hidden background become visible.

Besides that, i found out that the foam is very important..Try take it out that original foam and listen, u will notice that the sound is leaking very serious.. but after put in the foam, all songs concentrate into your ear. Last time i didnt even play around with the foam. I just use the original foam that attach on the iem. After play around with the foam, i experience different sounds as well.. Therefore, make sure the foam u use is comfortable and suitable for u.

The foam that given
smallest with 2 layer - inside the small plastic bag
small - at the IEM there..
mid - at the plastic holder there
big - at the plastic holder there
big with 2 layer - inside the small plastic bag

After testing the foam, i found out that I suit the mid one foam and my relative also wear the same mid foam.
How strong the bass, i think that
x3i > bijou (3) > xbi

Hope can try bijou (4), and maybe it bass is same as the x3i

About the color of the bijou, i think they use color to label the class of the bijou
Ruby - 1
pink - 2
gunmetal - 3
black - 4

great.. now i have to get pink...haha..is the bass heavier than x3i? muddy?

Thanks for you post, this calm my soul a lil.. because after 30 hrs of burning in, it still can't beat my Senn PMX-60, feels like a thin cloth is covering the bijou's mid and high, i was getting a lil anxious.

hehe,you will get the real power of Bijou after 100 hours burn in.

My right earphone sometimes mute and got no sound at all, i have to twist the wire anti clockwise then it's back to normal, is it normal to be like that? O.O

It could be the audio jack problem, did you try plug it in another device and see if got similar issue.

What i meant was my right side earphone mute but the left side is ok. I have to twist the cable under the earpiece and it's back to normal =x.

connectivity issue. Do get them checked / replaced.

After 80 hrs of burn in, the soundstage improved a lil bit and muddiness become a lil clearer. I notice that now the female high pitch sssssssss (like you want to say "sound" but drag the "s" sound for a little longer) sound is too sharp it somehow hurt my ear. My 4yrs old PMX-60 still perform better overall.
More burn in! more!!!

omg, today my Mylarone Bijou broke !!!
The left earbud split into two piece ...
Anyone can teach how to fix it? To glue it back ...

Dun do anything first. Call Yuheng and let him know what happen. Seek his advice in what to do.

why yours break so easily? I handle them quite rough, and they are still ok.
Just that when taking out from ear need some skill. Pull the wire to take out is a bit scary.

btw, how do u guys wash the foams?

send b for warranty?

Did any of you guys have high sensitivity issue around frequency 6kHz? the ssssssss sound is too piercing.

not enough burn in?

I burn in for more than 100 hours, how long does it require?
120hours now, while overall improve a lil bit more, but still the staging is not good. some instrument sound will another background instrument sound and singer voice is somehow feel like the singer is singing behind a veil but the music instrument is playing in front of the veil, not stand out enough. Is it the expected sound signature?

I'm a previous user of sennheiser PMX-60, could i be expecting too much? but i think if PMX-60 is selling now, it could be a lil bit cheaper than bijou.

Bijou does sound abit dark compare to previous Mylar according to ClieOS's Bijou 3 review, so Bijou is best synergy with brighter source

ya,i heard the X3i is very bright.

ClieOS did review on this Bijou and rated it

http://forum.lowyat.net/topic/722890

He rated it lower than the X3. Does anyone really sure the Bijou is an improvement actually?

Well maybe its bit dark and suits different taste. I fond of treble, bright, and clarity. Light on bass

i dun like the bijou 3 as well.
the first impression was really bad.
maybe the sq will improve significant after burned in?
