At the moment android app can't connect to T71. But qudelix is going to make it possible with future updates.

Is that to say that iPhones can connect?
No, it won't. iOS doesn't support it.
Special USB-C connector, using TX1+, TX1-, CC1, D+, D-, SUB1, RX2-, RX2+, single-end (see post #30)
In case you haven't seen it, the Qudelix-T71 User Manual is available. Sad to see that the final design no longer has a rotary volume control that was shown in post #27. The volume control has been changed to two buttons that are exactly symmetrical with two other buttons on the opposite side. It makes for poor ergonomics that forces you to really pay attention to which button you want to press (the 5K also has a similar issue). An asymmetrical design is better for operating by feel without having to look.
The device doesn't seem interesting unless used with the dedicated surround IEMs. I will wait for feedback on those.

Hi, I have read the website and the user manual but I am not sure I understood it well + I've never used any qudelix product nor software and still have some questions:
1. Can it receive multichannel audio and output the same multichannel audio without processing or processing each channel separately? Or can it only receive stereo?
2. Does it work in Linux?
4. Can channels be inverted and summed to have, for instance, 4 balanced channels or 2 balanced+6 unbalanced?
4b. In case the signal could not be inverted within the device, would it be possible to feed the device with some channels already inverted to then sum into balanced?
Thanks.

They ditched the volume wheel a long time ago, before launching the final product. I would have loved a wheel, but the buttons work very good, way better than the Qudelix 5k ones.
The device is very interesting even without the dedicated IEMs.
It makes a difference with regular stereo headphones. Watching multichannel content and games sound more engaging and dynamic, with better imaging. This is very noticiable, specially with the Sennheiser HD800s.
So Id recommend it if you play/ watch content with sorround sound.
AFAIK, there is no available adapter/cable yet. The only thing Qudelix has announced is a multi-channel IEM connecting through this USB-C port.
I don’t think I can solder a DIY USB-C adapter cable, except if I start from a breakout board
1. Yes it receives up to 7.1 pcm. If you're not using T71 IEM it will perform downmix through its 8 channels dac.
2. Yes, it works on Linux. At the moment I'm using it with moodeaudio on pie zero w 2.
3. Not sure what you mean. But at the moment you can adjust volume of each channel independently.

From the description it's not just an active crossoverSurround IEM: still not released, but from I could read in the Qudelix forum, it’s not going to be a surround IEM, but a quad driver (1 DD, 3 BA) with active crossover. Still unique and therefore interesting, but I was expecting……. more

What makes it not a surround IEM? Each surround channel on a separate driver, as you would do with surround speakers.

The T71 itself is definitely 8-channel capable. But if the 4x drivers output into a common nozzle in the ear canal, isn’t it equivalent to summing the surround channels upstream with a 1x driver IEM?What makes it not a surround IEM?

AFAIK, a pair of 4-way active speakers is not equivalent to 8x individual speakers positioned around you.
I was hoping for an “IEM” simulating surround perception—something where, for example, each driver would target a different part of the ear pinna, or something else…

They made something with enough channels to be able to try a few things. So we will see what they come up with. Being able to tune an external cross over for some iems should be interesting in itself. Making a convincing surround iem could take a lot more work. I'd probably look at it from an iterative perspective.
Does anyone have one and have any opinions on using it predominantly in stereo? I wonder if it will measure any differently with regards to SINAD.
