I received my Sennheiser MTW2 75th Anniversay Edition on Friday, and it sounds pretty good so far, I’ll have more thoughts later ... unless wireless is frowned upon in this thread ...

Tripe

As were the rest of us!...guess some guys can scoop up every release as though it's just monopoly money - where's me kit-kat?

Eh, some people don't pay anything for theirs.

Penon Volt Currently listening to Coldplay's Yellow with it out of my DX220 Max, the Volt is really something.

Eagerly waiting for some comparisons with other EST iems like the Trio and EJ07

Well obviously....

Waiting less eagerly!

btw, I noticed that the upcoming Shanling AE3 is using a BA that has a vent for the bass.

Been a bit interested in getting another BA only iem and that vented BA bass in the T800 is quite impressive. So this might be pretty good (especially since I couldnt find any other BA only iem that is using vented BA´s for the bass, except the T800 and the Fiio FA9).

Certainly an interesting proposal , vented BAs .. thoughts on fiio fa9 soon to follow

I don’t know a lot about ba drivers, but why aren’t there more releases with open ba drivers like the 64 Audio tia designs? It can’t be due to price since the Mini Mest uses open bas and it retails for $599.

Perhaps open bas are too expensive to implement in the < $200 price tier.

Not sure if you are referring to vented BA´s or if "Open" BA´s are something else, but if what you mean is a BA with a vent we do have a few of those.

Like the Knowles 31618 that is used in the Audiosense T800/Fiio FA9 or the Sonion 2354 that is in the upcoming Shanling FA3.

But those types of BA´s in iems do seem quite rare.

No I meant open ba drivers without a top to the casing so tubing isn’t necessary. They are supposed to be a refinement of typical closed case ba drivers with better performance, at least how I understand it.

oh, that is new to me then. Guess its not going to be in many iems then since that seems pretty new. Unless I have been in a cave all this time

Would not most crucial be implementation?
Original BA design still makes most sense to me - directing sound into a nozzle, given that the nozzle is an intrinsic part of the IEM design.

Sony makes theirs like this...

Then they built a holder they fit into. BA without the whole top isn't something I have seen. Link, pics? If they are "supposed to be" some kind of refinement than they exist but I have never heard of a BA that does not funnel through an opening only that the opening either has an output tube or not.

64Audio tia drivers?

 

[jant71]

Okay I do see the 64 Audio implementation now. Like the Sony with more open side. Not sure if you could detect a difference really? Quality of the speaker itself being equal. Sony vs. the Tia implementation in their holders. Not sure about these days but I was always a golden ears and I doubt I could tell a difference. Of course...

If you have that tubed BA right behind it then doesn't that have the issue you are trying to fix and then you aim that and it's waves right through that open armature path. Not buying in in that configuration for sure.
