The new drivers up close.
David Carnoy/CNETAs for sound leakage, I should note that despite the fact that these have open drivers, people standing nearby couldn't hear my music unless they stood very close to me -- and even then they couldn't tell what I was listening to. In other words, there's very little sound leakage, which is obviously a good thing.
To be clear regarding audio quality, the OpenRun Pro 2, which certainly aren't cheap at $180 (but cost the same as their predecessor), don't deliver sound on par with some of the top noise-isolating earbuds, including the AirPods Pro 2. They're not quite as dynamic, nor can they match the bass response of those buds. But they sound open, offer good clarity and decent bass performance and are among the top-sounding open earbuds out there. They arguably sound slightly better than Shokz's own OpenFit and OpenFit Air earbuds.
Ultimately, the key here is that you no longer have to sacrifice good sound quality in exchange for the advantages of bone-conduction technology. And that's what makes the OpenRun Pro 2 the best bone-conduction headphones on the market, even if they have a technological cheat to get to that title.
