Shokz revealed its brand new OpenFit 2 model at last week's CES trade event—naturally, this second generation open earbud plays successor to the original OpenFit model and will exist alongside the already released OpenFit Air (a cheaper alternative). Shokz's OpenFit series utilizes air conduction rather than bone conduction technology (as used by the OpenRun models) to deliver audio into a wearer's ear canals.

The new Open Fit 2 features a Shokz-designed DualBoost driver system—an "extra-large" 17.3 mm composite material dynamic driver produces lower/bass frequencies, while an independent high-frequency unit takes care of its namesake and mid-frequencies. TechPowerUp inspected and handled Shokz's new flagship and enjoyed the feel of its signature "Ultra Soft-Silicone 2.0" outer layer. Shokz has revised the Open Fit 2 earhook design—they believe that its updated shape should provide a better fit for the majority of owners.Bone conduction technology was showcased in the form of Shokz's OpenRun Pro 2 models. Two variants were available for handling—normal-sized and a smaller "Mini" version. These flagships feature DualPitch technology—a bone conduction system delivers precise mids and highs, and a dedicated air conduction speaker pushes out rousing bass frequencies.Examining small-sized portable audio hardware can be taxing on the eyes, so TechPowerUp savored a larger-scale mockup that provided an exploded view of a Shokz earbud's outer shell and inner contents.
