Q: How effective is the active noise cancellation (ANC)? What scenarios is it best suited for?
A: The earbuds feature Hybrid ANC+ENC technology with a -35dB noise reduction depth, effectively minimizing mid-to-low frequency ambient noise (e.g., traffic, air conditioning). Ideal for commuting, office work, or travel. High-frequency noises (e.g., sharp human voices) may still be partially audible, but overall immersion is significantly enhanced.

Q: Is switching between two connected devices complicated?
A: The Dual-Device Smart Switching allows seamless audio transition. When a call comes in on one device (e.g., phone), the earbuds automatically pause media playback on the other device (e.g., tablet) and prioritize the call. Manual switching via touch controls is also supported for non-call scenarios.

Q: What’s the actual battery life? How long does charging take?
A: Single-use playtime reaches 8 hours (ANC off), extending to 35 hours with the 400mAh charging case. The case supports wired/wireless charging, requiring 1.5 hours for a full charge. A 10-minute charge provides approximately 1.5 hours of playback.

Q: Are the earbuds comfortable for long wear? Will they stay secure during intense workouts?
A: The ergonomic design and 9 included silicone ear tips ensure a customizable fit for most users. With IPX4 sweat/water resistance, they’re suitable for gym sessions. For high-intensity activities (e.g., running), we recommend using smaller ear tips and adjusting the angle for a tighter fit.

Q: Do the touch controls cause accidental triggers? Can I customize them?
A: The touch-sensitive area is optimized with anti-misinput algorithms, requiring deliberate taps or slides. Pre-set controls include play/pause, track skipping, and call management. Customization isn’t currently available but may be added via future firmware updates.

Q: How stable is the Bluetooth connection? Is there lag during gaming or video playback?
A: Bluetooth 5.4 ensures latency below 100ms, eliminating noticeable audio-video delays for movies or music. For competitive gaming, enable your device’s gaming mode for further latency optimization.

Q: How clear are phone calls in noisy environments?
A: Dual mics per earbud and ENC algorithms isolate your voice from background noise. Testing shows clear voice pickup in environments like streets or subways, though extreme noise (e.g., concerts) may slightly impact call quality.

Q: Can I use a single earbud independently? Does ANC work in mono mode?
A: Yes, either earbud can operate solo. However, ANC is automatically disabled in mono mode to conserve power, while ENC call noise reduction remains active.

Q: Are there compatibility differences between iOS and Android devices?
A: Core features (ANC, touch controls, battery life) work uniformly across platforms. Advanced functions like auto-switching between Apple devices may require iOS-specific optimization. For optimal performance, pair with devices from the same ecosystem.
