So you’re saying the dongle should be larger to deflect Tupperware, and you think the smaller size could lead to damaged phones?

You are correct - I completely ruined a lightning port on an iphone a couple of years ago with one - Hilidac Atom 2 IIRC.
Generally USB-C is a little better for stability but I would still be hesitant. Shame as the form factor is so good - wonder why noone uses those snap off magnetic connectors for dongles that you can get on USB cables…

mid-bass and lower-mids area (fundamentals) is the target. Ideally bass shakers should operate way lower though, as they are meant to be a good substitute for an actual subwoofer in speaker setups for people that doesnt want to disturb the neighbours.

I think that shape is fine though, but you are right that the straight ones (JCally JA3) is scary.
I believe its cuz they arent strong enough, the connection is looser and will disconnect easier.

There was a brand that implemented is called GARAS magnetic cable. I got a 2 of these cables several years ago. Searched for them just a while ago and they aren’t available anymore. They are still working but they aren’t high speed enough for huge data transmission.
The main reason these magnetic connector design isn’t implemented by a lot of companies is of the designs may not have enough data pins to carry the necessary signals for data transfer, many are primarily designed for charging only, with a limited number of connection points in the magnetic connector, making data transmission unreliable or impossible.

There are quite a few, even in the budget realm, that also have data transmission as the pin out is standardized so it’s optional on implementation. The issue is spec adherence to enable marketing on the speed due to the connection issue you mention above - but for audio it should be fine as you only require USB 2.0 speeds. For large tech backing and higher speeds - safety issues are theoretically valid on these connectors but a little overblown in practise but I can 100% see from a management risk perspective why they would move away.

does it think its like those dongles from fiio that gives you 5-bands or does it access 10-bands? 
it uses the Fiio web app so the webapp thinks it is their Fiio JA11 so the same 5 bands as it. The key point for why, is because it uses the same dac& “KT02H20” anything with this will work with the fiio web app it seems.

lets say you have soundsource or similar software on your computer and then a qudelix or JA11. what would be the best place to do the signal processing, in the computer or in the device.
its not a direct andswer to what you wrote but perhaps you know whats beneficial if there even is any difference.

I would stick to using the software meant for the hardware, with the JA11 for example, it is saved to its own memory which I think is a big advantage as it is also less straining on your pc (probably only a worry if you have an ancient potato pc).
Not sure if other stuff with the KT02H20 chip also has a similar memory saving function though.
I would only use a 3rd party software on the pc if the stock one doesnt do what you want (lack of bands for example).

So with speakers, its usually subwoofers’s and with IEM’s its around bass to mids. I wonder how this tech would evolve and be implemented in IEM’s especially with brands that focus on bass. Any speaker setups you know off that have BC ?
Sub bass transducers used in speaker systems typically compliment air moving subs. I’ve tried one in the past and it’s a bit of a party trick for music but great for movies. Feeling the explosions etc is great without needing 120dB volume.
They could be good for sub replacement in some situations though I suspect the neighbors would still feel it as that is what they feel from subs. The lower the frequency, the longer the wave, the further it transmits through effectively anything.
Wavelength of a 20Hz signal is 17.15m or 65ft. That’s how it simply passes right through floors and walls. It doesn’t matter what kind device creates the wave…

How can speaker setups have BC? Are we supposed to strap the cabinets to the sides of our skulls?
Yeah, I’m being a smartass. But I don’t know how that’s possible. Enlighten me!
Typically they are firmly bolted to the chair or couch in the sweet spot. They are not BC per se as they don’t contact your bones but they are sub bass transducers nonetheless.

the speaker version is something like this.
which you install on your chair or sofa.
I guess there is a similar thing with those clothes that has it built in.
The reason why iem bass shaker BC types cant go that low is simply because they are too small, its physically impossible for them to operate lower due to lack of size/mass.

Ah … So, basically the same thing as a Buttkicker for gaming chairs. Now I see the light!
Thanks for the schooling.

Same tech. Also used in bed frames for the jiggle massage.

You’re spot on about sub bass transducers being great for movies, adding tactile feedback without high volume. Low-frequency waves easily travel through walls and floors, so neighbors might still feel vibrations even with transducers.
