QCY T27 ArcBuds Lite TWS Earbuds, Black,

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.

Audio Engineering

The QCY T27 utilizes 13mm dynamic drivers to reproduce full-spectrum audio. Bass response extends down to 20Hz, while treble clarity reaches 20kHz. Consequently, users experience balanced sound reproduction across all frequency ranges.

Built-in noise reduction technology filters ambient sounds during calls. The integrated microphones capture voice clearly while suppressing background interference. Therefore, communication remains crisp even in noisy environments.

Power Management

Battery optimization allows up to 7.5 hours of continuous playback per charge. The charging case extends total usage time to 30 hours through multiple recharge cycles. Quick charging functionality provides 2 hours of playback after just 15 minutes in the case.
