What were the headline revenue and earnings numbers versus consensus estimates, and what drove any variance?

I’m sorry, but the excerpt you provided does not include the actual revenue, earnings or consensus‑estimate figures for Sound Group Inc.’s six‑month 2025 results. Without those numbers, I can’t identify the exact headline vs. estimate variance or explain the drivers behind any out‑ or under‑performance. If you can share the specific topline results (e.g., revenue, net income, EPS, and the Wall‑Street consensus numbers), I’ll be able to break down the variance and highlight the fundamental or market factors responsible.
