Got my hands on the new Polaris yesterday. Initial listening impressions straight out of the box (usual caveats apply - will be a few weeks before I can give a proper assessment on the sound): This is a "fun" IEM. Bass is large and in charge - reasonable control for the quantity on offer, but not quite at Atlas out Vega level. Quantity wise, this has plenty of mid and sub bass, with a good woofer like effect on bassier tracks. Stays pretty well behaved on tracks with no bass in the mix, so feels pretty true to the recording in that respect. Detail is again decent but not anything over and above and you expect in an IEM at this sort of price. Fit and cable - top notch. Don't have my Android any more, but the housings almost feel a tad smaller than the OG shells. Probably just my memory playing tricks, so will leave other members who have access to both models to comment on that. Shift to pre-moulded ear guides from memory wire and the twisted cable design from the higher end models are both welcome additions. Isolation is decent given the driver vent, helped by the bass. Overall tuning - somewhere between L or W shaped to me, with enough clarity up top to stop things sounding dark. Warm, engaging tone - won't be the last word in detail or clarity at this price, but a very enjoyable listening experience, and another distinct flavour in the current CA lineup. Reminds me a little of the Dorado. More notes once I've had a chance to get some decent lightening hours in.
