Looks like a generous package! Does it also come with that splendid rug for my IEMs?
Sadly, no. While I'm partial to Persian carpets/rugs I doubt we'll ever see the day IEM's come with carpets. (They're coasters btw)


As for the Heart Mirror Pro, it's basically a balanced Heart Mirror.
I've been ill so havent spend as much time with the Heart Mirror Pro as I wanted but here are some early observations.

The sound quality is good as expected of a Heart Mirror. It has a more polite treble and more bass, great news for those that found the original Heart Mirror a bit too much. The sound signature is definitely in the same family as the original Heart Mirror, clean and detailed. (is that a thing? sound family's?)
It scales with power just like the original so a source with more power is recommended.

The increase in the bass quantity is less than the graph would suggest and quite welcome along with the improved detail retrieval in the bass. The mids haven't changed much if at all so far I can tell, which isn't a bad thing. The treble is reduced but it's not gone by any means. The treble of the Heart Mirror Pro will be preferred by most here on Head-Fi but for me I like the treble of the original more, but i'm not disappointed here. The quality of the treble is the same as the original.

For the accessoires it's pretty nice, good selection of tips, the included case is larger and is enough to contain everything, if just barely. The cable with swappable terminations is nice but the resistance of the plugs to being removed is lower then all of the similar cables that I own. Don't get me wrong, it's not that weak. The jack will come out of the socket well before the jack comes of the cable. I would like it to be more secure, but at least I'm not feeling like I'm breaking something when I do swap the termination.

Summary:
Improvements
  • Heart Mirror: balanced edition
  • Better detail retrieval in the bass
  • The increase in bass quantity allows it to perform better in a variety of genres
  • Scales with power
  • Nice accessoires, especially case and the cable with swappable terminations
Downsides
  • Not a evolution of the original neutral bright tuning, just a side grade
  • Reduced treble (subjective)
  • Detail retrieval in the mids and treble is the same as the original
  • Same soundstage and imaging as the original
  • Potentially worse layering and separation (need more time)
  • Needs a more powerful source to get the most out of it
  • Swappable terminations have the least resistance to being removed of all the similar cables that I own

I'll probably post some more of my thought later but for now this is what I've got to say about it:

The Heart Mirror Pro is a good IEM but it's more of a side grade to the original than a evolution. It doesn't stand out in my collection like the original Heart Mirror does. The Heart Mirror Pro probably will be the preferred one of the two for a lot of people but I don't know if the sound quality is worth paying twice as much as the original for what is basically a side grade with better accessoires. The Heart Mirror is really good for it's price but the Heart Mirror Pro is priced the same as the Aria and Titan S and I can't say if it's worthy of standing among them as I have neither.

Oh, nice! How are they compared to Olina? I thought that they quite common

Appreciate you adding that info!

Another interesting thing I found scavenging Weibo is that the Stellaris is coming out on the 28th in China. This is what Google translate is providing me with:
  • 14.5mm Planar Magnetic In-Ear Headphones [stellaris]
  • 1um sub-nanometer ultra-thin diaphragm
  • 2um precision etching circuit
  • Build transparent and melodious sound
  • Hear the clear and precise layering
  • September 28
  • CNY: 699

Watch this be the biggest chi-fi disappointment of 2022, I'm calling it.

Oh it's out, a bit more expensive than I thought.

Electroplating bottom shell...so it's actually just resin?

Penon Vortex is not exactly a discovery, as it has been out for a few months. However, the very few impressions online tell me how much under the radar it is flying. Here is an impression - I have not heard better Texture and Details from any other IEM at $200 range. Read below to find out my full impression:

Its metal plated resin.
mostly resin underneath but there is thin layer of metal on top that give that metalic feels.

i didn't know that you could electrocoat resin

Ductility.....such a word in construction I’ve never seen used. It means pulling, like into a wire, yet never breaking before going into desired form/shape.
Its metal plated resin.

To coat plastic, and any surface in general, it would be electroless plating.

For cold Canadian winters, the plastic inner shell is much more friendly for outdoor use.

The low sensitivity of PR-1 should make it challenging to drive optimally.

I ordered one anyhow, since I did not get CCA planars and curiousity (no other justifications...)

Then my most optimistic hopes for KZ is to make planar hybrids someday, so the mids can be well presented :)

I didn't know either and it's kinda "innovative". I thought the PR1 would be their first full metal IEM but now it's a bit disappointing gotta say.
KZ first full-metal IEM (not counting older single DDs) was BA10 - absolutely beautiful aluminum alloy shell (perhaps other than ear friendliness).

Anyhow, there will be always be people "disappointed"/whining/disgruntled with KZ, which is perhaps related to the fact that KZ makes hard to match cost-effective IEMs.

So I tried EQing my BL-03 until it sounds neutral with bass boost to me.

Maybe I need to get some Tanchjim filters instead of using dried disinfecting wipe paper as filter.

Or maybe it's was a counterfeit all along and no one knows they even exist. Not even me.

If anyone's curious.
