    Has anyone tried these shells in diy projects? I have two pairs and the fit is very good in my ears plus they accept 15.4mm drivers. If someone managed to create good sound with these I'd be interested what kind of drivers/tuning are ideal.

    I measured the frequency response and the problematic area is typical of small shell earbuds, with a little EQ it can be easily smoothed out: pull down the 3k-6k range by a couple of dB, especially around 3.5-5k. Plus a small boost below 100hz and slight decrease around 200-300hz will help the bass to become tighter more focused.
    Actually this 3-6k range is my most common problem with earbuds, it would be awesome if some kind of physical mod could target this area in isolation :) yes I know tuning foams help, but often they're not enough or have unwanted side effects, I'll experiment further.
    I'm really impressed with the extension and linearity of this mx760 from 9-10k upwards, this is what truly sets it apart in my collection. Amazing rich and realistic upper treble, airy and immersive. By the way below 1.5k the frequency response is almost indentical to Qian69 and they do sound very similar.
    I ordered virtually the same driver in mx500 configuration so it'll be interesting to see the differences in a bigger more capable shell.

    Another question: is it possible that RY4S UE has EMX500 drivers? I've just opened mine and they look exactly the same as aliexpress listings of emx500, but I don't have those to compare directly. The tuning is a simple horseshoe foam similar to vido, nothing special the drivers are bare.

    I would not be at all surprised but I do not have the UE version to check

    I could take photos but they really look exactly the same, I have a pair of emx500 speakers on the way so I can compare them when they arrive

    I put the ry4s ue drivers into a white vido shell and they gained a character similar to vido - V-shaped sound with heavy-hitting bass and recessed lower mids, but the treble response remained quite similar to the original so still bright and clear. These tuning foams do matter a lot! Not my favorite sound signature but it's quite good for a punchy v-shape character. I plan to try these drivers in the meizu shell as well (which I posted above)

    Do you know how to remove printed text from shells? I have a blue vido shell in which I put RY4S UE drivers and it sounds fantastic. (the y cable version of blue vido which is tuned flat - edit: thicker tuning foam inside) But the white Vido print bothers me. The shell has a glossy finish which might complicate things and I dont have a spare one to test chemicals.Thanks!

    Interesting, looks like Edifier H180/185 shells that I really enjoyed few years ago (I have two pairs).
    I almost destroyed one pair once I was training to remove drivers from shells, lol, so maybe I will give a try! didn't know they were snapping perfectly 15.4mm drivers :)

    I use nail polish remover to get rid of the print and a buffing block to bring back the glossy finish.

    Can DP100 shells snap on mx500 drivers? Or they can only accept mx760/dp100 covers by default?

    By the way I've just checked out NSC Audio store on aliexpress where I've bought the mx760 set and they put out a lot of really good deals!
    Just a small selection that caught my attention:
    https://www.aliexpress.com/item/4000247263113.html (5pairs of transparent dp100 shell under 5usd)
    https://www.aliexpress.com/item/4000250922044.html (maybe these are the same 19-21khz "carbon" drivers @HungryPanda recommended?
    https://www.aliexpress.com/item/4000220039317.html
    https://www.aliexpress.com/item/4000230474907.html
    https://www.aliexpress.com/item/4000173977762.html
    https://www.aliexpress.com/item/4000220132187.html

    Also some other nice listings I've found recently, in case it helps somebody:
    https://www.aliexpress.com/item/32990395829.html
    https://www.aliexpress.com/item/4000039814518.html
    https://www.aliexpress.com/item/4000214445948.html

    I dont know what they can snap on that's why I'm asking. :)

    Thanks for the suggestion!

    Well you could try it if you have a spare one, and tell me afterwards :wink: It would be nice if it could snap on the mx760 driver for example, maybe even tame the upper mids a bit. This is the reason I'm thinking about dp100 shells too. These form factors are usually offer a good fit for outdoors and the big shell + deep position usually adds a bit extra warmth/depth to the sound.
    I've put Vido drivers in the meizu shell and tuned it to sound warm/balanced with medical tape temporarily. Very good fit and pleasant non offensive sound for long term listening/walking outdoors.
