No, I do not have it. I listened to it for 15 minutes or so once but I do not remember enough to have an opinion.

They’re not huge but bigger than most of my other sets.

They’re comfortable though and while they do stick out more than other sets I can lay down on a soft pillow without discomfort. Or a firmer pillow not so much.

I have what I would consider regular size ears, I normally wear an M or L size tip, but sometimes I can go down to an S for logger nozzles with deeper insertion.

I’m currently wearing an M size with my mk3. If I switch to Tri Clarion I can wear an S since they do go in deeper.

By the way, for optimal sound reproduction with IEMs, you want an insertion as deep as possible. This is why Etymotic has that style of insertion, to take out the acoustic impedance of the ear canal as much as they can.

With the Monarchs, if I use a larger tip and shallower insertion the treble gets dull. This is very obvious if I gently push on the IEMs, the treble comes alive right away, hence my choice of going to a smaller tip size.

I got mine a while back.

They are truly monitors, very judgy IEMs in my opinion, crappy records will sound like crap.

Good ones will sound amazing though, extremely natural, no harshness, no zinginess, no hiss, it’s obvious the drivers are high quality.

I have a large-ish IEM collection and Monarch mk3 are up there with the best of them.

Now, personal and totally subjective, they have a lot of bass. It’s fantastic bass mind you, but for me it’s a smidge too much, with certain genres like EDM and electronic. Easy to fix though.

I also had to tip roll. The included tips are ok but not great and while here, the whole package is pretty underwhelming.

I had to bust out my tip box and I’m currently using some IKKO tips I found to fit and sound great. I also liked the Tri Clarion tips too, wide bore to tone down the bass, good sound.

Anyway, they’re great and worth the money IMO. If you have any questions, let me know.

Regarding your title, it’s not high impedance output - no one wants high impedance output as output impedance should be as low as possible, close to zero ideally.

It’s just output that can increase the voltage to power less sensitive and high impedance headphones.

That’s all, it’s just more power basically, it doesn’t directly make it better, even though typically Apple’s audio outputs are good quality.

Kinera Nanna 2. Nothing else I have comes this close to the sound I seek.

I’ve been in this hobby for 10+ years and I own multiple kilobuck sets and too many cheaper sets.

If the store has a proper name, has been established for a few years and has 95+ user ratings it’s normally safe.

Stay away from stores created very recently.

That price looks legit, the PR2 was never expensive.

The SPL calculation does not reflect reality and should be ignored mostly.

There was a thread on their forums for this exact issue and how displayed 100+ dB SPL felt like 75 dB SPL and their support wasn’t very helpful.

They said it’s maths done in a vacuum and that’s pretty much it, it’s not an actual measurement so just ignore it.

For me they look way too bassy, I’m not sure I would enjoy them so definitely not buying without a listen first.
