Description
Connectivity and Performance
Furthermore, the T27 model incorporates dual-mode connectivity for seamless device switching. The earbuds maintain stable connections up to 10 meters from paired devices. Additionally, each earbud can operate independently, allowing single-ear usage when needed.
Low-latency audio transmission ensures synchronized playback during video streaming and gaming. Moreover, the T27 supports multiple audio codecs for enhanced sound quality across different source devices.
