@FiiO @FiiO Willson Thanks for the response! Got 3 question I'm really interested in:

1) I see you released the very compact LC-BT1 that has a dedicate AKM dac-chip. Why is it that you couldn't include a dedicated DAC chip in the UTWS3?

2) LDAC (or APTX HD alternatively) - while indeed, there's no such thing as TWS earphones with LDAC on the market (although according to leaks, Sony's upcoming WF-1000XM4 might have LDAC) - why is it that LDAC isn't present on any TWS solutions? Is it impossible to implement/eat too much battery?

3) Why did you chose to make the lid out of aluminum and the body out of plastic? Is there e technical reason? My only feedback about it is that although the aluminium looks good, there is a clear texture/visual difference between the 2 pieces, and the TWS3 as a result, when you look at the case, looks a bit like a "frankenstein"

As a side-note/feedback - I really hope that for your next TWS adapter, you make a "locking" mechanism for the lid hinge - it's a bit annoying on the UTWS3 that whenever I open it to take out my earphones, the lid does not stay "locked" open and I need to hold it with my finger - a locking one (like in every other TWS earphone case) that holds the lid opened would help a lot!

Thank you and appreciate your R&D for all these awesome products!

Cover that hole with epoxy putty. Or sugru. Just some random idea ✌

Oh, ok. I had thought about it. I thought about having a couple of transparent "domes" 3D printed. Two things are stopping me. First the fact that I'm not sure looks would improve, second being unsure about how exactly to glue a 3D printed "dome" on top of an aluminum satin finished lid.

Also, the original case for my CIEMs perfectly fits the UTWS3 case inside it (it was too big before, now it comes in real handy).

We originally had added ambient sound mode, but there were some problems during the debugging process.
Some users will help us test the ambient sound function, and later, if we can fix it, we can upgrade it through the software

Of course, if you are willing to add ambient sound after purchase, and help us test, you can private message me to get the software.

I sent a message! Do let me know!

Hello, for your question:
1,There is no separate DAC on the UTWS3, only a separate AMP. As we have highlighted before, this is an innovation on our part, and very few products do this. In fact, the next generation will use a discrete DAC and will definitely be better, but of course more expensive.
2, LDAC can not support TWS earphones now, Sony currently not have very reliable solution.
3,Only metal can be attractive, many TWS headphone cases are designed in this way, I'm sorry you didn't like it.
Thank you very much for your suggestion, we will evaluate your comments

@FiiO Willson I have the 2pin version of UTWS3. In the case of "QDC/paragraph C" connector type IEMs like Blon BL-03 and CCA C16- is the pin arrangement opposite? So, R IEM should be technically plugged into L earpiece- and vice versa- in order for the correct pins arrangement?

Thanks for the response!

Maybe you didn't get me correct - I did not say that metal is not attractive - i was talking about the difference - metal lid, plasti body - they don't look the same, they have different shade of black.

Why not make full metal case? Maybe cost...

In any case, when you said, at point 1) "the next generation will use a discrete DAC" - do you mean you are already working/concepting the NEXT UTWS (4?) and already have plan for a discrete DAC (like ESS/AKM) ?

The bird is out of the cage so...

It will be UTWS5. FiiO always goes for odd numbers in model name.

Well, I can't say too much right now.
Because there is still a lot of uncertainty

 

[ClieOS]

I suppose the global chips shortage + AKM fire is not going to help either...

We understand.

We just hoping for something that maybe will get some new LDAC version from Sony that is stable for TWS and some discreet AKM dac That would be AMAZING!

Also maybe "transparency mode" and slightly smaller or no L/R colored indicators For some IEMs that have specific colors, it might ruin the design a bit.

According to the feedback from a user using Ultimate Ears Triple.Fi 10, the answer is yes.

Oh this 2 pin design... it will not work for a lot of IEMs in the market that comes with recessed 2 pin connections.

Why @FiiO @FiiO Willson, why design the 2 pin as such, it baffles me...

Dear friend,

You could check whether this help you to confirm:


The length of the pin:
3.6±0.15mm

Best regards
