can i just ask, there arent many dynamic custom IEMs around right? so far only know mg6pro from FS, a1d from aaw. any particular reason why? maybe cos DD harder to fit/tune as the shell will affect the sound more? hmm.

i know there are quite a few hybrids around but i think im just not used to or maybe dun like the kinda sound coming out from BA drivers. have tried
UM merlin and feel that the sound is very... separated. i could tell the diff between sound coming from BA and DD.. haven't tried many other BA iems yet though. so not sure issit cos of the separation in the bores or what.

1. It's not easy to volume match dynamic drivers
2. It's not easy to tune dynamic drivers
3. Size of drivers make optimal placement of dynamic drivers in shell more difficult
4. DD and BA drivers behave very differently to frequency phasing due to change in impedance

to further add on to that...

size of bass port, positioning, pressure, type of acoustic foam is critical.

Also, due to the unique shapes of our ears (inner and outer), the phasing of sound inside of the ear is affected very much as manufacturers have to tune towards the intended sound.. it is much more troublesome and time consuming compared to BA drivers.

manufacturing consistencies of dynamic drivers is lower than BA drivers; in production line, BA driver is more reliable in terms of delivering its sonic performance.

Updated with what I think are all the brands (except 1964ears, as from their website there is no local dealer).

Let me know if I missed out any.

I know E1 have 1964 demo units(used to, not sure if it's back yet). Logically speaking, they should be able to order too, if not there's no point in having demo units..

Well, from this page, E1 isn't listed.

Well I spent quite some time looking into the r&d process of AAW's A1D, for DD drivers, placement requires more delicate handling and sound bore size needs to be carefully deliberated. Do them wrong then some frequencies are totally gooooone....

Shell chamber size, acoustic dampening material, bass port and wiring play a secondary role. However, honestly speaking, nobody will get exactly the same sound from a DD CIEM, your ear size is different, canal bend degree is different, but that's the fun in it, isn't it?

Generally speaking, average sized ears or bigger will get close to the universal demo sound. If your ears are small, I would seriously recommend hybrid or full BA CIEMs.

The A1D took months to get the sound perfect, now along with its bigger brother W100, another 9mm DD driver CIEM, it does add more variety to the CIEM world.

Another reason I guess why most makes don't offer DD CIEM is the manufacturing inconsistency. One careless mistake in installation, you are looking at a dead driver

Well said!

Thumbs up for Kevin from Null Audio.

So other than the W100 (which I need to update) and the W300, will there be a W200 and any information on it?

Dropped by Null yesterday to check out the Hidition lineup and got to hear the W100 and W300 prototypes. W300's bass and mids were really good, but unfortunately the treble is bad and needs serious retuning IMHO.

Not sure about a W200 but I believe a 4 driver model is in the works according to the lady at the shop. Btw Kevin, do you do retermination services? I need a new plug for my Twag to fit my iPhone case...

are there any close competitors to unique melody mentor? it's quite good on some songs. on the others which it didn't shine exceedingly well, i suspect it might be due to the source and a lack of superior amplification.

i tried the new westone w60 and it reminded me of westone es5 (which i sold after few months haha). sound's more warm and intimate.

looking for an airy, good soundstage and balanced sound that is not biased towards any genre but presents all genres well.

Comparing a well burn-in es5 and a rather raw w60, imo w60 is the best out of their entire new w and um lineup (coincidentally also the priciest haha) but it's quite different from the es5. Um mentor based on demo imo is snappier and crispier but treble seems thin and may pierce on certain tracks. I think es5 still has the qualities you have described

Here are some of my suggestions:

1. Fitear C435 (treble might be a bit forward)
2. Fitear Private 333 (one of the most neutral iem, mid centric)
3. Noble Kaiser 10 (very versatile iem, but might be too warm)
4. Rooth LSX
