4.3 Selling Point vs. Decision Driver Alignment

4.3.1 Alignment Analysis

Current market communication of core selling points aligns well with users' primary decision drivers, especially regarding 'voice amplification', 'vocal protection', 'portability', and 'long battery life' which address urgent basic needs. However, a gap remains between sellers' claims and user expectations/experiences concerning 'sound fidelity' (particularly feedback and distortion suppression) and 'product durability'. Users frequently complain in reviews about feedback, distortion, product fragility, and overstated battery life, indicating unmet promises. Additionally, while 'comfort, stability, and battery life of wireless microphones' are increasingly important as differentiators and partially emphasized, they still require refinement to avoid misalignment (e.g., sellers heavily promote wireless features, but users experience short battery life or discomfort). This signals opportunities for innovation and differentiation in addressing these pain points.

4.3.2 Key Findings

• Users seek 'clear, distortion-free voice amplification' as their core requirement, yet existing products commonly fail at 'suppressing feedback and distortion'. This indicates room for improvement in fundamental performance and presents a key opportunity for differentiation.
• Portability and long battery life are standard in entry-level products, but users expect higher performance in wireless microphone comfort, battery life, and stability. Wireless experience is vital for product upgrades; optimizing wireless microphones is critical for user satisfaction.
• Product durability is a recurring concern, especially regarding fragile components like microphones. Improving materials and structural design while extending warranties can build user trust and reduce after-sales costs.
• Some users show rising interest in extra features (e.g., music playback, recording) and aesthetic design, reflecting personalized and multifunctional demands. Beyond core functionality, differentiated features and appealing design can attract specific user segments and elevate brand value.
