I saw these yesterday on Hifi-Go. The company who makes them is Daruma-Audio and it looks like they could be well that KBEar's japanese connection as they say on their site they did OEM for other brands and shells are like that of Believe and Diamond and the guy who run this company seems to be chinese.

Are there any graphs on their iems?

I couldn't find any. All the info says, as per perhaps poor translation, is that drivers of the T-500 are proprietary and of near pure Be performance.

Looks like an OEM KBEAR BElieve?
The might be the original source though.

"as a group of engineers Dharma Audio who has a track record of undertaking various OEMs from cheap mass-produced earphones to special models equipped with dozens of BA drivers in the 400,000 yen class for 15 years at manufacturers in the United States, Japan, and China."

Just few thoughts on GK10 and the hype:

DT-6 and DT-6 pro of S...r are tribrids at ~$25.

If to resend them to few reviewers for their "unbiased opinion", we can safely "unbiasedly" bet that they will be very noteworthy and really great price/performance ratio :)

The question what would drive 8-Ohm IEM was largely left unanswered, so saving $45 for popcorn makes it really enjoyable to watch where this hype train will drive to, thank you! :)

Honestly, that's the exact reason why I took a punt on them. I had both S....r models and in fact gave away the non-pro version to my office colleague.

Pro version is good but still doesn't hold a candle to any of my other IEMs. And, my 90% collection is under $50. I really want to test this hype train. And yes, that 8 ohm impedance is a critical factor, to get a source that is able to drive them without putting unnecessary stress on the IEM is important. I had played too safe for last 2-3 years, so went a bit rogue with this one. If it works out then great, if not, well it's Chi-fi and we roll on😂

I'm not sure I can interpret what you're saying here...

Although I am categorically 'all-in' on this hype train, I've made my descriptions as objective as possible. As for driving the GK10, I've found more power helps the DDs shine. Hiss is only a slight issue for me on my sources (Shanling M8, high gain) and amp (Cayin C9, low gain). I couldn't put a number on what is 'sufficient' or 'adequate' as I don't have many sources/amps to test, but I'm currently pumping about 4 watts into these without issue, clipping or distortion but with minor audible hiss.

It sounds great out of the Shanling M8 on turbo gain, which is rated at 840mW into 32ohms.

It is the output impedance that is worrying because of the low impedance. With only 8ohm, you would want a source that is no more than 1 ohm in output impedance.
otherwise you get hiss and possible FR changes.

Considering it is a relatively easy to drive IEMs with low impedance and high sensitivity, wouldn't that much power lead to some damage to the circuit or even worse your hearing? Because I'm sure they might be super duper loud even at low volumes.

I appreciate this, what's reassuring for me is my C9 handles it well and what I hear is excellent. I look forward to seeing FR graphs and what changes occur by output impedance.

Exactly! For this IEM, even cable change would actually sounds believable because it will definitely alter the FR and also potentially deviate from the intended signature

Interestingly, on low gain on the Cayin C9 I get to about 10-11am (audible at about 9am) on the volume pot, which would suggest theres plenty of room to play with this power output.

The high currents needed are exactly the problem.
Very few sources that I know are claimed/certified to drive IEM below 16 Ohm.

Those with high-level DAPs will be surely fine, but not the majority of people subscribing to this hype train...
