Built another pair of shells and tuned the 40Ω Ti drivers. They live up to their 'deep bass' moniker (listed by the seller) as the extension is very good.
Bass extension is very similar to the 150Ω redfilm. Treble rolls off after 5k, good for those that have treble sensitivity.
WowI just finish this MX500 "over-ear" mod prototype. I never have a proper fit with regular MX500 shells and I've been looking for a solution for some time. This concept (mmcx or cabled variant) can be worn over-ear or str8-up.
I use the "cable" version for over-ear, just put soft cable, and U good to go
The mod is not so easy to make but its worth itHi! I am a big fan of all your creations, could you tell me more about this one? I would love to make oneHi there! long time no see, I'm still enjoying a lot my new hobby: freestyle drone fpv
Is there anything better than our best favorite drivers 19-21kHz since @robar ?
I'm still amazed by my mod, they are so far the best earbuds I listened since so many years now.
All my other earbuds takes dust. Each day at work, coupled with my ES100, it's a pure joy.
Sometimes this earbuds DIY hobby miss me but I have so much to do with my drones now that I don't have enough time to go back to earbuds DIY for now
Cheers' everybody, keep safe!
. This also produces a closed-back effect which is good if you want to use earbuds outside.
Thanks for sharing, nice mods! I plan to build something finally with my dp100 shells anyway, mabye I can try something out from your mod.*** ShoonTH ESEP-01BL “Gold” mod ***
After 70 days my last order finally arrived from Penon Audio. ShoonTH ESEP-01BL is an entry-level earbud in ShoonTH lineup.
Unlike this model, it is obvious that more expensive models have more OHM's and better quality cable. At first, I was a little skeptical about the headphone shell
because so far I don't have any model with the same shell but it turns out that this model has slightly better ergonomics in terms of fit.
The only thing that really "stings my eye" is the cables with which I had a bad experience on earlier models because it degraded the sound a lot.
This one has ok wire inside, not sound so bad, but still overall look and feel is not nice so I decided to swap the cable and to explore "what lies beneath the hood".
The driver inside is an old school japan-made Foster drive with very promising specs. Original tuning is mid-centric with good extension on both ends,
but what is characteristic about these earphones and what sets them apart from other cheap models is imaging.
Another thing that is interesting here is the more intimate sound, something like closed-back headphones, but in the right sense.
There is much less noise from the outside than in the classics earphones, which is really weird, and that's another reason to see what's going on inside
And then came the first problem, how to open the hard-sealed earbuds without damage the driver. In my experience, there is a 50-50 chance to fail.
The first attempt was to put the shells in a plastic bag and soak them in warm water to soften the glue. This failed.
The next try is riskier, I wrapped the shells in aluminum foil and lightly heated the joint between the driver and the shell with a lighter. This worked.
BTW I don't recommend this method, especially on plastic shells. Anyway ...
The main trick here was to block the opening on one side (inside ear - rear side of shel) to create extra pressure that is released only on the rear side
which is not covered by the ear. A very clever move
The only drawback is that it reduces the sound stage. I mostly use earphones inside so I decided to remove hot glue, remove black foam, cut it to two pieces
and place it only to cover shell back vent ports.
For this mod, I used RY-C15 cable because it is soft, lightweight, and can fit easily inside the shell. I added a small piece of shrink wrap to prevent
unwinding and pulling the cable out of the shell. Also, brock small pin from silver parts to open small holes on the back of the shell.
In this way, a little more pressure can be released from the shell, but in this case, it does not go directly outside, but into the neck of the shell.
And this is the final result. Mids are still in front but not as much as in the original, the bass is better defined, is fast, and not interfere with mids at all.
Treble is smooth, but on the other hand, the soundstage does not go so much in depth but more in width, and It is followed by really good imaging.
What kind of foam did you put on the vents? Regular horseshoe which comes with sets of mx500 shells? Did you leave the cable opening open? My main problem with (transparent) dp100 shells was dark upper mids/treble, which made the sound muddy or at least dull for my taste. Will try 19-21 drivers next time, but these shells are really comfortable with thin covers like the one shoonth has or the type of steel mesh which the N50 driver has. By the way, isn't the "outside vent" covered by the ear (sits towards the back of the head) and vice versa?Thanks neighbor, I'm glad you like it.Thanks for sharing, nice mods! I plan to build something finally with my dp100 shells anyway, mabye I can try something out from your mod.
I promised to make a "short" review when they arrive and here it is after a long wait.
,
by trying to separate them from the shell, now I have only HE150Pro so my plan is to try it again, of course not to destroy it
DAY10 LOCKDOWN
With so much time on my hands I decided to mod some Docomos and Kube V1 earbuds.
New colors
I have had a similar experience with this type of shells and 15.4mm driver. It's very good for mmcx mods but requires larger covers and serious sanding.
