By the power of E-stat
The ES hybrid has very good bass, impressive mid range sharpness and the best treble for its price. Loaded with plenty of details and a much more bigger than average stage size, it is difficult to sideline this power house named Pola.
comfort and fit
The lifting is done by the dynamic driver and two Estat drivers and the quality is very good, as good as things can get for around $800. The only problem is a bit of channel imbalance, it’s not a deal breaker at all.
The signature is slightly W shaped but that doesn’t take anything away from the mix of things, the full bodied bass and well extended treble mixed with the a big stage makes the experience a delight for any audiophile. The tonality is very neutral with fantastic precision with very good notes sharpness.
Burned for more than 150hrs, I am using the Plenue R and D for this review, the Pola need good amount of power and will not be easily driven out of mobile devices and thanks to the lower crosstalk values of mobile devices the Pola will feel very imbalanced.
TECHNICALITY AND MATCHABILITY:-
The Pola with its 101db sensitivity and 12ohm impedance is not very easy to drive out of any mobile device, driving it out of a dap is okay but If you dap is not powerful enough you will miss the best of the Pola. Power is what makes the Pola tick.
It matches pretty well with all type of devices, it is not much choosy. But if you use something like Plenue R it tends to down play the treble emphasis and makes the overall signature slightly drier.
Being Drenched with BA drivers, trying the Pola makes my feet tap. The full bodied bass with its dynamism is a delight for even someone who demands heavy bass notes from their IEM. The 13mm graphene dynamic driver delivers plenty of thump, details and clarity. It doesn’t go over the head like the Hyla TE-5B and doesn’t fly under the radar like some BA based earphone.
I agree that the bass quantity or the amount of air wont absolutely please a bass head but it wont leave them asking for it either. In other words, the Pola moves very good amount of air with a full bodied slam. The extension of sub-bass is deeper than most of the BA based earphones but is slightly less than the TE-5B, where TE-5B fails badly is with bass decay, that’s where the Pola pulls ahead with better clarity and details. The notes have very good sharpness to them, they don’t feel loose and the texture too is outstanding.
The Pola has slightly more mid bass body than the sub-bass, giving bass the required amount of fullness making it meatier and impactful. The slam, the air and the rumble makes the Pola’s bass enjoyable and sets it apart from the likes of Andromeda and other BA based earphone. The upper bass is nicely tuned with good amount of control.
The thing which sets the Pola apart from the Andromeda and the TE-5B is something which both the earphones failed to deliver. The andro takes the leaner approach with very good details but sounds lean where the 5B takes the other extreme with shit loads of bass losing some details and precision. The Pola middles that with near perfection, it has very good amount of slam and air, the level of details too is 2nd to none.
When you consider details, slam, air, body and tonality the Pola has one of the best balance for at around $1000.
MID RANGE :-
The mid range is delightful, the dynamic driver handles the mid range too and it does a fantastic job, the transition from upper bass to lower mid range is nicely done, there is little to no loss of energy in this region and has good amount of clarity. Yes it is not as flawless as the AF1120 or the Nocturnal Eden but it’s better than the TE-5B.
The mid range is nicely paced without being dull like the Fibae 3 and is not overly aggressive like the EM-5H. Instrumental distribution and density is as good as the Andro but the Andro has more forward mid range and delivering slightly better transparency.
It is nicely balanced with the bass region without being much into the V. There is plenty of detail and the bigger stage size helps a lot. The notes have very good body. They have the required amount of thickness to them and are not sharp at top, keeping any type of sibilance at bay.
Vocals on the Pola are very accurate with notes depth and details, it might sound slightly dry because it lacks a bit of note body as they have faster decay speed. But a bit slower decay and thicker note body would have sounded more natural though. The vocals have very good bite, when I switch from pola to the TE-5B vocals sound dull and muddier. Both male and female vocals sound equally impressive, both have very good details and accuracy. Male vocals retain good amount of throaty feel to them and female vocals maintain good amount of depth and sharpness with them.
Instruments have nice transparency and details to them and have required amount of sharpness, it doesn’t sound dull like the Fibae 3 and EE Bravado and more sharper notes would have landed in the thin category like the EM-5H. Upper mid range is slightly lacking energy when compared with the vocals and rest of the mid range, it still has very good weight with notes but is not as forward.
The stage size of the Pola is very good. It is bigger than anything you can experience for under $800rs. The stage is one of the biggest in its price range, bigger than the HYLA TE-5B. Good thing is the stage doesn’t feel hollow as the density of instruments is very good. Layering and separation is very good and there is good amount of air between instruments too.
The treble region of the Pola is handled by two micro tweeters and the result is outstanding, the extension feels endless and the amount of energy too is fantastic. There is plenty of sparks to it.
The transition from upper mid to lower treble is very good but not flawless, there is a small dip but still has good amount of energy and details to it. The Pola delivers one of the most delightful treble presentations with plenty of details and accuracy. The big stage size helps a lot with instrument placements and density. There is plenty of air between instruments and the layering and separation is fantastic.
Let it be pianos, trumpets or cymbals, they have fantastic amount of sharpness and the finishing of the note along with the presentation is very good. Let it be the resolution, transparency or imaging the Pola delivers like a champion. There is little to no complain about the treble.
The treble doesn’t shine out of proportion and does its work with ease, the extension and stage size is good enough to bring smile on any ones face.
