I didn't see a thread yet for these and have only seen these mentioned on the Discovery Thread, so I thought I would start a thread here for people to give their impressions on these. I have a set incoming (should be here between Feb 16 through the 22).... My Hermano @FranQL has me a bit excited to see what these are going to be like.

For those unfamiliar, here is what these consist of:

10MM Flagship Beryllium Dynamic​

Japan-imported voice coil copper wire, acclaimed excellent driver. After careful R&D and adjustment, Star river adopts a new generation beryllium diaphragm, which has the unique tone of beryllium metal diaphragm and ultra-high detail display ability.

6MM Titanium Diaphragm​

In order to maintain the metallic sound similar to beryllium metal and the overall overall performance of the earphone driver, TRI has customized a 6MM titanium diaphragm as a high frequency gain driver to achieve better high frequency output.

Four Tuning Models​

Star river uses a precision electronic frequency divider tuning switch to give the earphones four different tuning modes with different driver gain effects. Tuning switches: balance, low frequency reinforcement, for vocals, and pop flavor.

Ergonomic Design​

Adopts professional big data model to realize multi-dimensional equal pressure design in providing comfortable wearing, effectively avoiding ear pressure problems caused by wearing posture and human ear shape. Skin-friendly resin effectively prevents allergies and other problems caused by materials.

I picked up one as well based off of Akros youtube review.

I saw that review also, and it was also a part of why I grabbed a set... Have you recieved yours yet?

I have not. I don't think it has been shipped out yet. I got the 4.4mm Green version from the K Bear official store. I'd assume it'll be March when I get it and at the same time my Galileo should be in to. It'll be interesting to A/B a dual dd with switch and a much hyped collab 1DD/1BA at 2x the cost.

Bought 1 Star River for $49 USD too.

Usually I don't do blind purchases (there don't seem to be store graphs too), but the 2DD tunable concept is quite interesting. Hope it doesn't disappoint!

I got the same variant and connector. I love the looks of the blue also, but I have quite a few blue ones a this point. I ordered mine from the KeepHiFi store on Amazon. We'll see if they arrive when it is projected.

Yeah, I am the same. I normally at least wait for more reviews, if not the customer impressions on stuff like this. So, who knows this could come back to bite me. We'll see?! You can see some graphs from the video that @s2kphile linked, near the end where he measures all 4 switch combinations. It looks like there are really only 2-3 different variations on these. One is exactly like the 00 switch position, and another only varies VERY slightly from a different reading (I don't know if this is totally accurate or not). In case you don't want to watch the super long video, I took screenshots so I could at least post them here.

Do let us know your impressions once they arrive and you have some time to listen to them?

Thanks for the photos!

Yes will definitely do measurements on a coupler with the various switches and some listening impressions once they come. Likely will take about 2 weeks to reach me from China though, assuming the balloon it travels on isn't blown off-course or shot down by an F22 jet LOL.

Damn it, I was drinking something when I read this. I JUST about spit it all over the place....

I look forward to your readings (and thoughts) on these.

I nagged and got this from someone at kbear. Didn't answered my other questions though...

That seems similar to the one in the video review if a lot smoothed out (though I haven't looked at them side by side yet). I am surprised they sent you that. Thanks for sharing this.

Yeah, nagging and calling them out launching a product without a graph as a red flag got things moving over there apparently

I got mine in today. I JUST got them so have not even put them into my ears yet, but here are some pictures (very sorry about the bad camera work, and the poor camera quality):

Hos does the cable feel, soft to the touch? And is it silver-plated? Copper ones get to change color rather quickly.
Still waiting for mine to arrive...

The cable is rather soft and pliable. It doesn't seem to hold a memory at all. It is an SPC cable. It IS pretty thin but is actually pretty nice for being budget.

Man, I'm still waiting on mines to be shipped. I ordered from Aliexpress via Kbear Official Store on the 10 Feb.
