KZ PR2 Review! is it still KZ's best iem? (long ranty video)

[@colddish]

Dude you should listen to the v2 and you will not defend KZ’s choice of removing the mesh because it sounds horrible. I own PLA13, PR1 Pro and I have a couple of other planars, this PR2 v2 aka without mesh sounds broken! In the first place of the mesh solution is unreliable then it shouldn’t be implemented at all. It only means that the initial design is already flawed and instead of going back to the drawing board to redesign the iem, KZ decided that meeting the deadline is more important. It’s like a ship designed with a hull issue and the management decides to patch it with a duck tape! And so after finding out the mesh solution leads to low good yield they decided to remove it entirely and pray that people don’t hear the difference. They also claimed, during launch, that PR2 was supposed to be easier to drive, that is way off the mark! Being the cheapest planar is not an excuse either. KZ themselves have proven that they are capable of breaking the price barrier with good sounding iems that punch way above their price points. I’m not going to criticize HBB for keeping mum with this fiasco either. The one lesson I’ve learned from this disaster is that I will wait for at least 3-6 months after each KZ new launch before pressing the buy button if I like the what I read.

[@wahid-lg1kk]

I have the v2 and it's brilliant. Just stick some IBM micropore tape over the nozzle after removing existing filter, which is garbage and makes the sound chaotic. No it's not easy to drive you need at least 3.8Vrms swing.

[@Grrrr3FKAGrrrrGrrrrGrrrr]

I bought PR2 because my 7Hz Timeless is too precious to me to be wearing outdoors. Had to pause the video a couple of times to check which version I had, and again to give them a listen. I was expecting to find I had the revised version, linsoul delayed by delivery for a few weeks because they had run out, but the dampers on mine are in the same place. As usual, your description of the sound and it's pros and cons is spot on.

[@quangnd1503]

Haha me too. To me the PR2 sounds as 80% good as the Timeless

[@supra8087]

Reversed starline tips goes well with pr2. Smoothens sound and adds soundstage (that is already huge). Combining with a powerful desktop dac amp you get nearly max level of a soundstage an IEM can have. (V1mesh)

[@hi-friaudioman]

Nice! Yeah that's a pretty killer combo. Truly encroaching on kilo-buck territory if you ask me.

Great rant and review Hi-Fri. I love your format just the way it is. I really enjoy the work Micheal Bruce has done retuning the Letshuoer S12. He calls the Glamdring S12. I have a custom made flathead from Once Upon Audio (Budapest Hungary) that has a single DD blue PET 300ohm transducer. It is by far my best sounding flathead. I have often wondered how this material would work in an IEM form factor with a lower impedance.

[@hi-friaudioman]

I still have yet to try Michael Bruce's iem. Some day I would like to try it or replicate it if possible. Yeah I'm curious then blue pet material. I have a 10mm blue pet DD and it does sound pretty good but I think I like my normal pet and graphene DD a little better.

[@fiddlix]

@@hi-friaudioman it’s all relatively new stuff to me tbh. I’m an old tube head from back in the day, the electronics is an easy one for me, interpreting freq. graphs, harmonics and its effects on timbre and the inter working relationships is mind boggling to an old fart like me.

[@Mark-hb2zy]

I have the non mesh version. Stock its kind if nice at first but for me (and probably most people) the novelty wears off after a while and the treble really ruins some songs. However, whith eq, adding a tiny boost at 80hz to add some boost, taking the sub bass down a bit (it seems to lose all its slam with stock sub bass), bring down the upper mids and mid treble a lot and also the air treble, it now competes with my blessing 2 dusks. I think i might even prefer them which says a lot. For ny set nost of the uglyness seems to be in the mid treble, spending some time on that gave the most improvment. Removes the harshness, metalic sound and sibilance.

[@StarBuccaneers168]

Crazy how KZ could build a planar at a such a low price! Always enjoy your demo tracks, they are cool to play on the IEMs!

[@TheMausebert]

Thanks to your review I ended up buying the pr2 25 dlls and pr3 30 dlls on the 11.11 sale. I own other 2 KZ and the treeble spikes are completely mitigated by the EQ. Great quality for sound and price.

TRN T tips are great, are comfy and have good synergy to many of my iems :). They seal really nicely in my ear.

[@hi-friaudioman]

I totally agree, that's my exact experience. As for best sounding tips or best comfort, I think there are better out there but the T Tips in my opinion are the best all around. They just do everything well and suit a lot of iem's well.

[@yo3429]

Good point with the 'crackling' timbre. I made some custom tunings with the KZ PR and the S12, but never got rid of the slight irritating coloration in the lower hights. I guess that's the sound of the foil, maybe a (heavier) compound foil will work better or AMT style. But otherwise, next to very good 7 mm or 8 mm DD drivers, the planars are very audiophile sounding IEMs, never looked back to BAs, but still prefer single DD. You find the PR2 for around 40 bucks on ali at the moment. But better the PR1 and EQing the 7-10 khz region. You will keep the amount of energy beyound 10k

[@Hijynx87]

I’ve heard the newest ones ship without the black damper making it ear bleeding in the treble. I got lucky

[@isaiahschell]

“Ear bleeding” is a stretch. I’ve got the V2 and they’re absolutely fine. At least to my ears, the extra treble gives off a more precise sound.

Thanks for the reversed tip tip. Did that on my narrow bore Letshuor and now they can be used too. I sent you a message about Z300 a while ago but never heard back from you. I could have helped you out.

[@hi-friaudioman]

Sorry I may not have seen it. My apologies.

[@Radugazon]

Always very interesting thanks a lot. Anyway, do you confirm the efficiency variations : 99 dB for the PR1 pro, 96 dB for the PR1 HiFi, 94 dB for the PR2 ? If yes, this could imply that they used in the PR2 either a thicker diaphragm, either less powerful magnets....all cheaper stuff that could partially explain the lower price. I don't think they used a wider air gap 😁

[@hi-friaudioman]

I think the efficiency could also be because of dampening. 99% of spl measurements are done at 1khz, so naturally if the tuning was changed the efficiency @ 1khz could change.

[@jeeewhyyypheee]

I got the non mesh version. By some FR graph the upper treble really similar to PR1 Pro, dunno why is that. And also PR2 is by far the hardest to drive amongst planar species, maybe due to that lower sensitivity. And I already tried pairing TE Zero Red 10 ohm adapter with my PR2, it decreased the upper treble by 5dB and I really liked it. Thus by making it even harder to drive than it already did

I have never experienced such a drastic difference pre and post burn in, on anything.

What brand tape specifically did you use? I have left the standard mesh on the tip, but have been using some Sennheiser IE series tips (with the crossed bars in the end) so i can stuff some medium density foam rounds in there.

Yeah, you'll see the the mesh if it's the old version. You can always add more mesh or foam if you want and that should help. Also burn-in will help a little bit but it won't get rid of all of it.

[@oaktowndimond668]

If the "make or break" is a tiny piece of porous mesh over the driver, , then we got bigger problems. I have the "V2". I'm gonna guess the sensitivity might have kicked up a bit too without the mesh? I also bet KZ didn't like that low 94db sensitivity either. Listen, I like sparkly treble. I've had a pair of Yamaha NS1000M for decades. I play them with the grills off too. And I agree. Putting material over a planar only masks whatever inadequacies it inherently has.

The pr2 was changed to an unlistenable state shortly after release. They removed tuning foam and turned them into a completely unbalanced mess.
