The Polaris pursues a design that is more in line with Campfire’s armature based earphones than their dynamics featuring their larger, more angular housing shape. However, the Polaris assumes an intriguing two tone, two texture colour scheme that provides a very unique look and one that reflects the hybrid nature of its inner workings. While their aesthetic isn’t as subdued as Campfire’s previous designs, their choice of a rich blue is tasteful and the gunmetal Cerakote lid provides stunning contrast that looks a lot better in person than in photos and renders.
In terms of build, buyers get to relish in a delicious all aluminium housing machined in Portland, Oregon USA. As always, Campfire’s level of finish is class leading and no corners were cut when compared to their higher end models. After using the Jupiters almost daily for the past few months, I can personally vouch for the hard wearing qualities of Cerakote; those earphones, while mostly pampered, have been hastily pocketed and struck together with no visual repercussions.
The Polaris is no different, their gunmetal Cerakote lids remained flawless after my month of testing though their blue anodized housings did receive some trace chips here and there. I definitely advise winding the earphones up from the housings and storing with the Cerakote lids facing each other to keep them looking pristine. Perhaps my only gripe with their design are those silver screws which look quite incoherent, I feel that black screws would have fit the design of the earphones better.
Ergonomics are very similar to Campfire’s BA earphones given that the Polaris’ housings are mostly identical. However, the Polaris features a new nozzle design that does give them a slightly different fit than before. The nozzle is now plastic though it is incredibly solid, it’s longer than previous designs and smaller at its extremity permitting a deeper fit. I actually struggled a bit to find an appropriate ear tip though I eventually settled on the softer silicone tips included with the Dunu earphones. The Polaris also has a small vent on its outer face that does affect isolation, they still attenuate noise very well, better than the 64Audio earphones and as well as most sealed earphones, but they aren’t vacuum quiet like Campfire’s fully sealed models.
Furthermore, the vents make the Polaris very susceptible to wind noise, they aren’t unbearable like the Sennheiser ie800, but it is clearly noticeable when out and about. In addition, the Polaris suffers from some of the worst driver flex I’ve experienced though Ken has assured that it is within tolerances and I didn’t notice any sound degradation during my testing. Otherwise, the earphones are just as comfortable and stable as past models, staying put during a long distance run and forming no hotspots during extended wear despite their angular housings. These are ultimately minor quibbles that don’t impede normal use and are quite insignificant when compared to the comfort issues of the DK-3001 for instance.
At the top, the Polaris utilizes a removable MMCX cable with beryllium copper connectors. Campfire claim they’re magnitudes stronger than the usual brass variety, they’re very snappy with even tension on both sides and I experienced no intermittency during my testing. The Polaris is the first to use Campfire’s black Litz copper cable rather than the silver plated unit on their other earphones. Ergonomically, the cable is as excellent as before with the same memory wire system, low profile metal y-split and beefy yet case friendly right angle plug. I would have preferred pre-moulded guides as the memory wire is a bit fidgety and stubborn during shaping but I had no major comfort issues with the Polaris. The cable itself has a tighter braid than the silver Litz cable but resists tangles just as well. It’s also just as supple as the silver cable which is among the best I’ve come across. Due to the nature of the cable’s braid beneath the y-split, the cable is quite prone to becoming twisted though it does soak up a lot of microphonic noise in return.
