Great review! Do you think Trio is an update of Castor? I only listen to symphonies. My first IEM is S12 pro which is okay for violin and piano, but is bad for symphonies especially pieces from romantic period. My second is KZ ZAR, much better than S12 pro thanks to its dynamic and textured bass. However, its mid and treble are a little bid lack of focus (imaging? I don't know how to describe it). Now I settle on Castor bass version. Really love it.

dchen1109, I think the Trio improves on the Castor Harman (the version I have), but if you listen to symphonies you may prefer the PR3 which does have superior imaging and a better treble. This beautiful symphony sounds great on the PR3:

Thank you very much.

Wow, whats more musical than this? if even possible

Excellent review, as always. Do you prefer them to the T800?

I'm very excited to receive the hybrid pads since they seem to be everyone's favorite. I'll amend the review once I get them. Hope you enjoy your single sided!!

Ive got a bit of waiting to do but I know I will! Hard choice for me but I do main rap, edm, and rock so Im thing SS will be great for me- and the extra $500 to help upgrade the amp.

Good review, Man. Im glad you wrote it. We need all the perspectives.

I'm very eager to hear what it should sounds like when paired to holo audio bliss or Azure, Not meaning your gears are not good, but I think those can't sing tungsten well which has extremely low sensitivity, and those are even not enough for hifiman gear's neither.

Great review

Interesting you ended up preferring the cheaper Simgot.

Can you elaborate on the thin sounding mids? Which instruments, drums or percussion suffers on this?

@dezzadk snare hits suffer from the thinner mids. Instruments like conga as well. Mostly percussive hits lack the body and impact I'd expect. Baritone vocals also do not sound as "fleshed out" as they should.

Currently have the Scarlet in on tour, it doesn't touch the XE6 and THAT is the price you pay for what it does. Just be glad Fir isn't doing UM pricing.

Definitely pricing them out of reach for most consumers. Congrats they may sell 10 units. If it was priced at even $1500 it's still a major purchase for most consumers. I have no doubt these are totally awesome in every way but until the prices become more consumer friendly they are pricing them far out of reach for most. I would love to be able to hear a lot of the ( Flagship) gem's but for what I would spend traveling to a Can Jam , airfare, hotel, etc. I could actually buy a pair of $1500 buds ... as HBB says "at these prices these buds should crawl under the table and blow me" .. I'm not being negative or sarcastic but just stating the fact that it is what it is.....

@BDalton look at classifieds here and you will get some good deals. Unfortunately all good IEMs are getting crazy expensive to buy new.

Very well put up review.

Thank you

Nice review mate

Thank you

Listening to it now, it finally arrived. Great tight, non boomy bass, warm mids and detailed highs that sparkle. A great all round IEM, and as you said, an upgrade to the Ea500

Grrrrrrrrrrr, I literally just went to try an updated firrmware downgrade if that makes sense. After a completely full charge I open the case and notta, all power depleted, the left bud still have no operable use as far as I can tell. I’m about ready to throw these things out

IFI…PLEASE GET YOUR POOP STRAIGHT! I’m embarrassed for you! THIS OR advertise accordingly and stop misleading people. Who likes wires? if portable use to you means sitting in an arid part of the word on a cosier all day then I suppose you nailed it!

You may need to start a claim and have them send you a new set. I downloaded thr latest gaia from the website, disconnected the go pods, and after several tries, was able to connect both and roll back the firmware. I spent hours doing it though. Just file the claim on the broken set. If the other set isn't broken, then make sure you download the latest gaia to install, and then download the older firmware from there and your other set should be fine. It's either 1.49 or 1.42.

Thank you! I’ll do just that…..so frustrating. Enjoy your Sunday!

Great review, on my list for sure!

Unboxing experience and overall fit and finish as well as attention to details second to none — indeed

Is the bass impact a weak experience? Sounds dull? Sounds like it

Like for the captain Rex figure in the photos

The review is nice too

Got them at a place called "Book Off" in Manhattan. They have co loose figures. That's where these got scooped up lol

Deleted.....

Really well explained review. Hats off. I'm auditioning it at the moment and have to agree with your conclusions. One variation is that I have tried it with Moondrop Kato silver nozzles and I think that's the sweet spot with the 500LM. The questionable aspects are smoothed over and it becomes a more capable performer.

Excellent review
