Geo-exclusive entry-level true wireless earphones launch February 20 at ¥2,178 each, offering earcuff GRSPL-OWS 9168B and open-ear earhook GRSPL-OWS 9199B models.
Earcuff GRSPL-OWS 9168B clamps cartilage, weighs ~4.9g per ear, plays 7 hours (28 with case), uses 10mm drivers and Bluetooth 5.4.
Both models include low-latency gaming/video mode, hands-free calling, Siri and Google Assistant access, SBC codec, HFP/AVRCP/A2DP profiles, and USB-C charging.
Geo’s dual approach highlights two divergent philosophies within open-fit design rather than a simple cosmetic split. The earcuff model leans into minimal contact area and clamp-based retention, a choice that typically trades absolute stability for lower occlusion and reduced pressure hotspots. From a technical standpoint, the smaller dynamic driver and newer Bluetooth stack suggest an emphasis on power efficiency and connection robustness over outright acoustic headroom. This aligns with the “compressed feature set” narrative seen in entry-level wireless designs, where consistent pairing and predictable latency matter more than codec experimentation or DSP-heavy tuning.
By contrast, the earhook open-ear variant prioritizes mechanical stability and diaphragm area, which can be advantageous for maintaining perceived bass presence in a non-sealing design. Larger drivers in open-air configurations often rely on sheer surface movement to compensate for the lack of acoustic loading, and the hook structure helps keep the transducer aligned with the ear canal—an often-overlooked factor in open-ear consistency. The inclusion of a numeric battery indicator on the case hints at a more usage-aware design, catering to sports or commute scenarios where quick visual confirmation outweighs aesthetic minimalism.
Across both models, the reliance on the baseline SBC codec and standard Bluetooth profiles positions these earphones firmly in the pragmatic camp. Latency-reduction modes are implemented at the system level rather than through advanced codec support, reflecting a cost-aware engineering choice that still addresses video and casual gaming use. From an audiophile forum perspective, these designs are less about chasing resolution or staging and more about solving everyday friction points—comfort with glasses, situational awareness, and predictable wireless behavior—within the constraints of an aggressively accessible hardware platform.
