Key Features & Technical Facts
MagSafe-Compatible Magnetic Alignment: Internal magnetic array aligns with standard MagSafe wireless chargers to maintain stable coil positioning and regulate thermal dissipation during 5W power transfer.
Bluetooth 5.4 Transmission: Operates on a low-power wireless architecture designed to maintain audio-visual synchronization below 65ms latency under standard operational range.
Dual-Mic ENC Beamforming: Utilizes dual microphones to process and isolate ambient background noise from user speech frequencies in congested acoustic environments.
Capacitive Touch Interfacing: Touch-sensitive sensors integrated into both earbud stems provide direct control for track navigation, incoming call management, and voice assistant activation.
Ergonomic Semi-In-Ear Housing: Molded from skin-friendly ABS polymer with a 45-degree acoustic vector to fit diverse concha geometries.
