IOS Ecosystem Integration: Features pop-up pairing interface simulation, instant device switching across Apple IDs, and battery status synchronization via standard iOS BLE profiles.

Spatial Audio Simulation: Built-in 6-axis gyroscope supports dynamic head tracking emulation for supported multimedia tracks on iOS devices.

Ultra-Low Audio Latency: Advanced RF tuning achieves an end-to-end audio transmission latency of under 65ms, eliminating lip-sync lag during video playback.

Dual-Mic ENC Calling: Beamforming microphone arrays isolate ambient noise up to 25dB, ensuring clear voice pickup in open office and transit environments.

Capacitive Touch Control: Direct playback control, call management, and voice assistant activation via responsive touch sensors on the earbud stem.

 

 

 

Playback Endurance:

• 6 hours of continuous audio playback at 50% volume (AAC codec).
• 30 total hours utilizing the 400mAh capacity charging case.

Rapid Charging Technology: A 10-minute charge in the case provides 90 minutes of playback time.

Battery Safety & Chemistry: Utilizes high-density, grade-A polymer lithium cells equipped with over-voltage, over-current, and short-circuit protection circuits on the PCB.

 

 

Firmware Customization: Re-flashing of BLE broadcast names, MAC address prefixes, custom EQ tuning curves, and touch-control action mappings via factory programming jigs.

Enclosure Customization:

• Injection-molded ABS/PC plastic casings with customizable Pantone color matching.
• Surface finish options: UV high-gloss coating, matte rubber-oil spray, or metallic electroplating.
• Packaging Customization: Tailored retail box dimensions, custom paper stock weights, hot-foil stamping, and serialized barcode labeling.
