A super tweeter, made small.

AAW x Shozy POLA

A super tweeter, made small.

POLA is AAW and Shozy’s electrostatic hybrid: a large 13 mm graphene woofer and two electrostatic super tweeters, arranged as a loudspeaker would be.

The aim was never a better specification sheet, but deeper immersion: bass with depth and layers, a full and charming voice, and the small details of the room around the music.

  • 13 mm Graphene dynamic driver
  • 400 V On the electrostatic plate
  • 108 dB Sensitivity
  • 12 Ω Impedance, easy on a phone dongle

Six Micrograms of Gold

Electrostatic

Six Micrograms of Gold

Each electrostatic super tweeter is a gold-plated membrane weighing six micrograms, held against a plate charged to as much as 400 volts. A miniature step-up transformer inside raises the signal up to a hundredfold, and the music itself draws and releases the membrane to make sound.

No energiser, no separate amplifier: plug POLA into your player and it is ready.

A Large Woofer, Like a Speaker

Woofer

A Large Woofer, Like a Speaker

Beneath the electrostats sits a large, fast 13 mm graphene-diaphragm dynamic driver that moves a great deal of air, paired with them as a loudspeaker is paired with a super tweeter. A vented chamber and the TrueXross 2-way crossover let it work at its best.

The result is deep, layered bass, a full-bodied, charming voice and fine detail in the ambience of a recording.

A Year in the Making

Design story

A Year in the Making

POLA is a collaboration between AAW and Shozy. When Sonion’s new electrostatic drivers, with their miniature step-up transformers, arrived in early 2018, the aim was not higher numbers on a sheet, but more enjoyment and immersion in the listening.

The first POLA, shown at CanJam in early 2018, was a 3D metal-printed universal with a smaller dynamic driver. Through 2018, prototypes with armatures and other hybrid layouts went to shows and private listening sessions for feedback; a year of research ended in the design you see here.

Wonderful IEM with new electrostatic technology

In my opinion, POLA has the following characteristics:

1. Well-controlled and detailed treble which is not irritating.
2. Smooth and sentimental vocal, when other IEMs with BA will have occasional presence of sibilance but that is not the case for POLA.
3. Deep and booming bass, that is the most brilliant part of POLA and I can really hear very deep and layered bass as described.

Moreover, a powerful DAP or portable amplifier is needed to drive this giant and a certain run-in period will definitely boost its performance to another level.

Fantastic enjoyment on Female Jazz vocal music

With the airy sound stage, sweetly treble, smooth mid, tight and controlled bass, it’s a new and great experience to listen to Female Jazz vocal with Pola! It’s more enjoyable to listen to Pola than W900 although the fit with W900 is better for me. Great work to AAW and Shozy!

Pola's

I've only had these a few days so these are very initial impressions.
I use these with a Hiby R6 pro out of the 4.4 balanced port with the (very nice) Hakone cable.
They have a rather odd, boxy shape that will definitely stick out from your ears.
Everyone's ears are shaped differently obviously and I could not get any workable fit/seal with any of the silicone tips. For me, the large foam tips work fine though and give me a comfortable, secure fit. I definitely don't think anyone would want to use these for working out/jogging etc..
I'm not really an audiophile in the sense of accurately describing slight differences in timbre and fine details. I do have however several earphones in this relative price range and I know what sounds "good" overall, at least to me.These are very capable overall and sound better than my CA Jupiters, Vegas and my JHA custom 13somethings.
These have OUTSTANDING bass. If bass is your thing, look no further, you're done.
I'm sure thats from the insane 13m Dynamic Driver. At first I thought they were rather "muddy" due to the bass but the rest of the sound range seems to be opening up nicely with
more use.
I rate them a strong 4 stars but not 5 simply because I also own RHA CL2's and they can't
match those but I'm not sure anything (at any price) can. The RHA's are just cleaner, tighter and faster. Perhaps with more use the Pola's will scale up. I'm definitely not disappointed with these however.
I also want to say the service from Null Audio was top notch and I can't recommend them highly enough. Su answered my MANY questions promptly and was super helpful at every step. Many thanks!

Questions

Good to know

Does POLA need an energiser?

No. A miniature step-up transformer inside each earpiece raises the signal for the electrostatic tweeters, so POLA plugs straight into a phone, a laptop or a player. A good player or amplifier with more power, and well-mastered recordings, will let it show more of what it can do.

What is the driver configuration?

A 13 mm graphene-diaphragm dynamic driver and a dual electrostatic super tweeter, joined by a TrueXross 2-way crossover, with a vented chamber for the dynamic driver.

Who is POLA for?

Listeners who want the air and detail of electrostatic tweeters with the weight of a large dynamic woofer. At 12 Ω it plays from a phone or a laptop, and it grows with a better player or amplifier.

What warranty and returns apply?

POLA has a 1-year warranty on the monitors and the cable. Unused universal IEMs in their original packaging can be returned within 14 days of confirmed delivery, with a 30% restocking fee. See shipping and returns.

Do you ship worldwide?

Yes. Most countries get free shipping by EPAC, and FedEx Priority is free on orders of USD 250 or more. In Singapore you can also pick up from our studio at 76 Playfair Road.
