I'm not 100% sure how you mean it with grounding, but I think that nobody is using grounded pin on 4.4mm connector for headphoens. Similarly 2.5mm connector also has no grounding pin. For example here is pinout on 4.4mm adapter from Cayin Adapters from MEE Audio

I like these connectors, but isn't it annoying to have L-shaped connector, that is longer than most DAPs on market?

You can also count me among Mellianus fans.

More likely that on this demo the connectors got stretched by people inserting cables that shouldn't fit. It might fit fine for now, but if you try to go back to proper UE connector, it will likely be too loose, will fall out and can have loose contact.

Sweet tiny rig. I always was tempted by the Rockets, almost bought them few years back in Japan. Maybe I should have a look at used market again.

And about double of average salary in Czech Republic. And about few dozens other countries.

Had mine 8CS done earlier this year, impressions done in their office, final customs delivered in 8 days.(same town shipping)

With them for some time, but this is my personal account(from which I don't post too often).

They definitely make custom versions for Japan, Hong Kong and China, try to email them to learn more.

It's new BT codec being pushed to the market mainly by Huawei, announced just few months ago. What will be its future? Nobody knows. And I think currently there are no headphones or speakers supporting it. Just take it as another rival to aptX and LDAC. Which codec will be the most used? Since...

Here is my older write up about them: https://www.head-fi.org/threads/flicker-ear-ciems-in-collaboration-with-pw-audio.870915/

Stop by at our booth on 14th floor. I will be there with few pieces of M0 to try ;) Good to know, will stop by right after my morning Ramen!

My solution for long bores on Samba - one size smaller tips, pushed all the way up to nozzle. This way I get really deep fit, that is much closer to fit of custom version. And they don't look like frankenstein's plugs anymore.

I'm using mine with Symbio Eartips

If somebody likes Oriolus that much, wouldn't it be better to get custom version directly from them? I saw custom versions in their offer on Japanese and Chinese/HK market
