I was 1st into better sounding earphone when my friend introduced me the Audio Technica Pro5V (if I remember the name correctly). I was amazed by the sound it made. It is incomparable to the cheapo pasar malam or computer shop AVF equivalent. Too bad when I was in uni the headphone is stolen together with a lot of my good stuffs. I was finding a replacement untill I stumbled on the UE TF10. That brought my musics to a whole new level. I bought it when it was on sale during black friday via a friend from the USA for $99. Ever since I loved that a lot. At 1st I was struggling with the fitting. It was not comfortable. But when you get a good fit, It sounded great. After a few months the cable gave way.... Meh.... Bought a replacement cable from Jaben and it rocks again. Being using it for quite some time. I knew a lot of people compared it to the Shure SE535 and I decided to go to Jaben to give it a try. At first I tried the SE215, what an incredible sound for an earpiece for RM389 (at that time), superb bass and the sound is ok (of course not comparable to TF10), and then I tried the SE315 SE425 then the SE535. The 315 and 425 was a disappointment for me. But the 535 was somewhat comparable to TF10. The 535 sounded warmer, with more sub bass than the TF10, more bodied mids, Celine Dion sounded superbly sweet!!! At first it was awesome to listen. I was quite pleased with the sound untill I played Armin Van Buuren songs........... DISASTROUS......... Treble roll off too much. The TF10 wins hands down notworthy.gif on this. The bass on the TF10 is so fast that it kept pace with the beat of trance music. In the end I felt it's two different thing. You cannot compare them both, both have their strong points and weaknesses. One thing to note thou was the fitting of the Shure design. It was marvelous. It's impossible to not fit. It is so "universal" that I bet even an infant would find it comfortable. **joking** But anyway I've always wondered, If I can get TF10 to fit in the Shure shell, make it sound the same with a little bit more sub bass and more mid, that would be the superb earpiece. Haha, but everything in the world is not so nice. Since then I've always wanted to make a CIEM, but the pricing and resell value puts me off. After my TF10 gave way, the right side bass driver KAPUT, got crackling sound whenever there's bass, I went to Jaben to sought out a replacement, preferably a CIEM. I've tried many many CIEM at Jaben. The one that really "CAUGHT MY EAR" was the Fitear 334 and 335DW. The Fitear 334 is almost perfect for all kinds of songs, adequate bass that goes very low (impressive for BA), the bass is more about quality than quantity, but it is just nice, the mids are very very very nice, it sounded so sweet without fatigue after long listening period, and the superb treble extension. The 335DW is the 334 with more bass since Fitear added an additional woofer for more bass. The bass is heart thumping and fast, it has the punch and goes very deep without sacrificing the mids and high on the 334. This is the best CIEM I've listened to so far. I've also made some research on what drivers actually fitear is using, and not only that. I've also made research on what other brands of CIEM maker are using as well. Why didn't I grab a Fitear yet? Yeah, good question. Look at the price!!! ROFL, poor fag like me will never be able to justify spending that much on what? a pair of earpiece???? So in the end I've decided to do something about that! Imma reshell my spoiled TF10 BY MY SELF! yes, you hear me right (sorry you all can't hear me)......... I AM GONNA DO IT! I am gonna try starting off by reshelling my TF10 into the Shure SE535 shell and modify the crossover, replace the twin bass BA unit to give it deeper bass and mids and try to retain the treble. Pictures to follow. [B]TO BE CONTINUED......

Since there are some updates on this page, I will post some pictures here on the first page itself on the progress. for those who wants more detail regarding this thread can browse the pages.

Nice. Looking forward to reading your progress.
I assume you would start by making a mould for an acrylic shell? Or silicone?
*
The acrylic shell mould process would be in the near future. I will acquire the items needed before I proceed with that. For now I will try to experiment with the SE535 shell. Should be able to work.

As mentioned earlier, here are some shots of the above mentioned "object". Enjoy rclxm9.gif

The TF10 itself in it's beat up state:
user posted image
have been using this for almost 10 years. Even after the right unit have a rattling sound

Complete Disassembly
user posted image
Actually this had been done some time before. Note that the dual low drivers unit have already been disassembled from the mini pcb itself.

The TF10 dual low drivers
user posted image
A closer look on the dual low driver shows that this is a Sonion 3300 custom made to UE specifications. It has the UE markings on it.

Crossover with the high frequency driver still attached to it
user posted image
The crossover utilizes a 20ohm resistor series and 3.5uF capacitor parallel to the low driver. This is a low pass filter to filter out the high frequency so the low driver will only receive the low frequency. The high pass passive crossover featured a 1.5uF capacitor series to the tweeter driver. Capacitors are AVX I assume based on the looks of it.

The Sound isolation silicone (I don't know what it is called) This is used to block the sound from the driver's tip to go backwards to the back housing. It directs sound to the 2 bores of the eartip.
user posted image
Note that it has a red filter for the low frequency and green damper for the high frequency

[B]Closer look on the Acoustic dampers

[B]The Tweeter driver on the TF10 (Has UE markings on it, another Sonion driver I assume. The 2389)

That is all for the disassembly of the TF10, Stay tuned for next update on my workbench. bruce.gif

The nozzle of the shure shell is thinner than the tf10. If you aren't making your own, a shell wita a nozzle size closer to the tf10 like this one would be better.

https://m.aliexpress.com/item/32700254654.html

Like that one for example.
*
I've notice that Shure has a nozzle smaller in diameter, but as I mentioned earlier, the Shure shell has one of the best fit in the world. So I want the good fitting and try to maintain the UE sound sig. Pictures of the tools I use for the project to follow......

I once had a Monoprice 9927 IEM, and it can reproduce the most realistic cymbals and acoustic sounds of all that I have ever heard of from any IEM. Not even the Shure 425 or the Sony XBA multi BAs have such treble performance. It had a single 14.2mm dynamic driver, and open back I believe. They don't hit quite low enough despite what the huge driver may suggest. They are more comparable to headphones than IEMs.

The entire build quality was crap though. Cable was very fragile, housing was ill-designed and had rough edges, and one of the nozzles were deformed slightly. The entire thing was huge too. If I have the sort of miniature electronic skills as you I would probably attempt to house it in a better shell. It's very cheap, USD 8.

Do you have a pic or any reference of the thing? Maybe I can mod it lol

Only pics from around the internet. I sold it for RM10 to a friend about 2 years ago, and the the cable worn out a few months later. The IEM was over a year old when the cable broke.

I was busy for the past few days, assembling and tuning the stuff, being not satisfied with the sound tuning and change it again. lots of soldering work to do. Soldering, putting it together and try to listen and then feel not satisfied and desolder the thing and solder it back. Keep repeating the same stuff...... In the end I got something I am quite satisfied but still can be improved.

Here are some pictures:

For those who are interested to "audition" this home made iem, can PM me and we can arrange time for meet up and test it out. Any sincere comments are welcomed. If it is not good just tell me straight and I will try to improve my future build. Next is to wait for my CIEM materials to arrive so I can try to make a CIEM. flex.gif

awesome DIY you have there... I have a underutilized TF10 lying in drawer that I keep thinking to reshell them to custom, been surveying which company to go for but then u sparks my brain that we can reshell it to other IEM body as well....

the one who own TF10 before know the sound is fantastic but the fit is major problem...
*
If you want I can reshell your TF10 for you as well and I have a superb upgrade cable for the TF10 too, i don't know if you trust snake oil or not. I am also venturing into making my own customs as well. I will try to make something equivalent to the Fitear 335DW. If you wan't to go into details please PM me.

The Upgrade Cable(I will refund you if it doesn't make any difference)

Can, no problem. You want the original TF10 crossover setup?
But you will also need the MMCX cable as well. I will PM you the costing and all. Plus the info.

Depends on what rewiring. If the solder point of your drivers are not broken, yes. If it is broken, sorry I cannot help.

Please send me a picture of it. I see what needed to be done. You want a full re-cable or just the jack? I only left some mini 3.5mm paillics with me. Oyaide will need to wait 2 weeks. And let me know your iem 4 pole 3.5mm or 3pole 3.5mm.

The current setup of the DIY IEM needs some upgrade of the drivers. I am gonna use the top of the line for my next build. Stay tuned, it won't be long for my next project.

I did a double take for a moment, your CD900st looked a lot like how mine currently are.

Have you replaced the cup hinges with MDR v6 parts to make them fordable too?

I feel that its rare not because it's hard to get but because you get what you pay for in terms of sound quality after shipping and handling when a few others in the price range offer slightly better value for money, the biggiest reason for someone to get one is if they wanted THE standard issue Japanese studio headphone or to try a near perfected version of the Mdr 7506, because the internals are highly modified compared to a standard V6 or 7506.

These are not mine smile.gif I got a request from a friend to mod it. Will upload the pictures after the mod.
