Your Phone’s Hidden Weakness: Lost Audio Nuances
User Question: "Why does my smartphone’s audio sound flat even with expensive headphones?"
The answer lies in compromised DAC hardware:

- Real-World Example：Testing Billie Eilish’s "Ocean Eyes" through the H2 revealed whisper-like backing vocals completely lost on Apple’s Lightning dongle.
