Let's get this out of the way: the Ola II has the trademarks of Tanchjim design. The DSP cable is good but sometimes a bit unwieldly, while the shells themselves have the usual distinct clean and even clinical look. The fit is a bit peculiar due to the very universal shape and tiny size, to the point of being a potential deal breaker for those that will not be able to form a seal. Personally, they are wonderful and have the same comfort as bullet-style IEMs that disappear in the ear.

As of late, they have deviated from their usual white/clear medical look they've adopted after the Hana 2021. The Soda, Fission, and now Ola are all lookers and keep that same aesthetic appeal while having distinct colors and quirks that make them stand out a bit more. The Ola II is on the more plain side of things, but the dark matte grey is definitely a looker!

As for sound, the Ola II is different from Tanchjim's lineup, opting for a more V-shape tuning while still retaining the mid bass and vocal emphasis character from all of the other 1DD. In a way, it reminds of the One without DSP, but with added air from the BA driver while having slightly less low treble glare. Overall, it sounds competent but it does seem to be more of the same from Tanchjim without much to make it stand out. 

Full review will be coming out some time next week, with the usual detailed measurements.
