Two specs define the connectivity story here, pulling in opposite directions. The JBL Sense Pro runs on Bluetooth 6, the latest generation of the standard, which brings improvements in connection stability, interference handling, and efficiency over the Bluetooth 5.4 found in the Shokz OpenFit 2. In dense wireless environments — busy offices, crowded transit, or multi-device households — the newer standard gives the Sense Pro a meaningful edge in maintaining a clean, dropout-resistant connection.
Audio codec support, however, flips the advantage. The OpenFit 2 includes AAC support, which is particularly significant for Apple device users, as AAC is the preferred high-quality codec on iOS and delivers noticeably lower latency and better audio fidelity over Bluetooth compared to the default SBC baseline. The Sense Pro offers no named codec beyond SBC, meaning it cannot negotiate a higher-quality audio stream regardless of what the source device supports. For Android users the gap narrows since AAC performance is more variable on that platform, but for iPhone users specifically, the OpenFit 2's AAC support is a tangible audio quality advantage.
Both earbuds share the same 10 m Bluetooth range, USB-C charging, and a notably sparse codec roster — neither supports LDAC, aptX in any form, or LE Audio. This is a genuinely split category: the Sense Pro wins on connection technology, the OpenFit 2 wins on audio transmission quality. Which advantage matters more depends on the user's ecosystem — those on iOS will likely feel the OpenFit 2's AAC support more acutely in daily use.
