My take on the Shozy Pola and Shozy Pola 39
the TLDR take is they are both amazing in their own right with the pola being the more relaxed of the two while the 39 takes the clarity and imaging up a notch. Both come with great kits but you get more with the 39 and to those who do have small ears the 39 have smaller more manageable ear pieces. Both have amazing detail and smoothness but I preferred the 39 for the added clarity and resolution. Both are very smooth and detailed
The Kit
Shozy Pola comes in a neat yet simple blue pleather case with the unit themselves greeting you as you open them in a foam insert it a very common lay out but it looks tasteful and gives you the impression it isn't your normal iem. The included cable is very nice and solid with minimal micro phonics and very comfortable with superb quality, you'd spend a pretty penny to get something better. The cylindrical connection at the 2-pin socket had me worried initially as i haven't had a unit with this style of plug before but its very solid and has a very snug fit in the socket it isnt going to come out with out significant effort. The included tips come in plenty of sizes and come with 2 pairs of foams for the review I chose my jvc spiral dots and they always fit me best without cutting the highs , but of course i recommend you use what suits you best. The polas come in this gorgeous dark wood finish that is really neat to look at and feels solid in the hands. These units have a good bit of depth to them and with stick out a bit and might not fit smaller ears.
The 39 on the other hand comes with a much larger blue case with pockets and various pamphlets and an gorgeous hand carved case when you pop this thing open you definitely feel like this isn't cheap very nice presentation and i feel a nice touch the cable is just as amazing as it is on the pola. Tips are the same fair with plenty to choose from and different tier sizes for the foam tips as well which is greatly appreciated, something i feel should be much more common place at this price point. The shells have the very beautiful gem finish on them with blue amazing shades of turquoise and light blue. The units in the one are small and smoother and should fit those with small ears better.
I used everything From R&B trance to classical Some of the many albums i used include the following
Gear used was my trusty EVGA Nu Audio with stock OP amp ADI OP275 at 24bit 192Khz
Lows: Starting off with the Pola in hits low and deep with a nice warmth that will satisfy you. Both have plenty of detail with the 39 trading some impact for a tighter faster presentation here but both units reach very deep. Neither are a bass head iem but they take EQ very well and can be taken to ludicrous levels if you wanted.
Mids: This is where there starts to be more a difference in tuning as each does it differently. The pola has a relaxed mid that is in-offensive and plays it safe but is soft for my taste. This isnt to say its recessed at all it just has a softer presentation id say speaker like if you where to try and compare it. The 39 has a lift and presents the mids in a more forward fashion that I find suits me better. The mids in the polas both have amazing amounts of detail and shouldn't disappoint anyone here but the 39s have more clarity to them.
Highs: The Pola give treble smoother than anything i have ever heard lending credit to the electrostatic tweeter it reaches skly high and never gets fatiguing to me high hats and cymbals have a shimmer and life to them that i haven't heard in an iem before and never gets harsh or over bearing. The 39s take this even further by offering a touch more energy and air giving notes more space.
Sound stage: Both units give great presentation and illusion of space with the nod going to the 39. The original Polas will wow you if you haven't heard space and separation but the tuning of the 39 gives a very airy presentation with larger spacing between notes
Imaging & Detail: Now if you got this far reading this you'd get the impression that the pola is dark but i can assure you its not. It is the darker of the two but far from dark sounding and has outstanding imaging and detail. With both units i was definitely hearing things in tracks i couldn't hear before. Lucia de lammermoor from the fifth element was notable on both giving breath and life to Inva Mula-Tchako's performance in a way i haven't heard before. The 39s however add more clarity and detail (if you can believe it) and sound completely organic in doing so. Most iems with this level of detail tend to offer a harsher or fatiguing edge that is absent on both sets. The 39s have over all more clarity and space over the polas with a touch more resolution at the slight expense of bass slam.
In the end both sets offer amazing smoothness and detail that I didn't know could come with such a smooth and non fatiguing flavor that is dangerously addictive. Both units are cut from the same cloth but I feel the efforts made by Shozy and AAW have taken the sound of the pola and refined it in the 39. If the price isn't a stretch for you id take the 39 and I cant wait to see what else Shozy and AAW cook up as they have created auditory magic , at least to me
Huge shout out to Ian at the source AV for making all this possible and to this amazing community. Thank you.
