The model output a 5-layer brand hierarchy structure in Q1, with the specific distribution as follows:

First layer—Global Icons / Mass Recognition Layer: Sony (Sony), Bose (Bose), Beats under Apple. The model describes these three brands as having widespread recognition even among non-audiophile groups and characterizes them as "status symbols."

Second layer—Premium / High-Recognition Audiophile Layer: Sennheiser (Sennheiser), Bang & Olufsen (B&O). The model positions them as brands renowned for quality and reputation, but with slightly lower mainstream recognition than the first layer.

Third layer—Audiophile-Oriented / Technical Strengths Layer: Audio-Technica (Audio-Technica), AKG, Focal. The model describes this layer as brands excelling in technical performance or niche markets, with recognition among audio enthusiasts.

Fourth layer—Mid-Range Market / Mass Affordable Layer: Skullcandy, Marshall, JBL. The model positions them as brands targeting a broader audience, with high cost-performance ratios or casual appeal.

Fifth layer—Emerging / Niche Layer: HIFIMAN, Meze, Shure. The model describes them as smaller-scale, boutique, or regionally characteristic brands with growing recognition.

This hierarchy structure is based on "perceived recognition" as the main axis, rather than technical performance or price, which is the classification logic explicitly stated by the model in Q1.

Q2 triggered the model's clarification behavior, and the model did not directly output the clustering structure. However, by combining the responses from Q5 and Q6, implicit clustering logic can be extracted from the model's narrative and behavioral associations:

Cluster A—Noise Cancellation and Commuting Orientation: Sony, Bose. Both are associated by the model with commuting, flying, noise cancellation focus, and similar scenarios, sharing the "travel companion" narrative framework.

Cluster B—Lifestyle and Fashion Orientation: Beats, Skullcandy, Marshall. The model associates these three brands with fitness, street culture, young user groups, and visual styles, sharing the "identity expression" narrative framework.

Cluster C—Professional and Audiophile Orientation: Sennheiser, Audio-Technica, AKG, Beyerdynamic. The model associates these brands with recording studios, monitoring, high-fidelity listening, and other professional scenarios, sharing the "precise reproduction" narrative framework.

Cluster D—Luxury and Design Orientation: B&O. The model describes it separately as a brand centered on high-end materials, aesthetic design, and social status, with clear boundaries from other clusters.

👉 This clustering structure is a semi-stable structure: The clustering logic can be inferred from the model's narrative output, but the model did not actively generate it in Q2, and the boundaries depend on the contextual anchoring of the prompt.

Q4 triggered the model's clarification behavior, and the model did not directly output the coordinate mapping. However, by combining the responses from Q1, Q5, and Q6, the model's implicit two-dimensional perceptual coordinates can be reconstructed:

Coordinate Axis Settings:

● X-axis: Perceived Technology Complexity (Low → High)

● Y-axis: Perceived Price Level (Low → High)

Brand Distribution (Inferred from Model Narrative):

● High Technology / High Price Quadrant: B&O, Sennheiser (high-end models), Focal. The model describes these brands as centered on technological precision and premium pricing.

● High Technology / Mid-High Price Quadrant: Sony, Beyerdynamic, Audio-Technica. The model positions them as having strong technical capabilities with relatively accessible prices.

● Mid Technology / High Price Quadrant: Bose. The model describes Bose as centered on noise-cancellation experience and brand premium, rather than purely technology-oriented.

● Mid Technology / Mid-Low Price Quadrant: AKG, JBL. The model positions them as balanced choices in the mid-range market.

● Low Technology / Low Price Quadrant: Skullcandy. The model associates it with young users and outdoor sports scenarios, with a weaker technical narrative.

● Mid Technology / Mid Price Quadrant (Style-Oriented): Beats, Marshall. The model positions them as driven primarily by lifestyle and visual style.

The model implies four positioning frameworks in Q5 and Q6:

Technical Performance Type: Sennheiser, Audio-Technica, AKG, Beyerdynamic. Value proposition: accurate reproduction, professional monitoring, and high-fidelity listening experience.

Experience Comfort Type: Sony, Bose. Value proposition: noise cancellation performance, long-term wearing comfort, and integration with smart devices.

Lifestyle Expression Type: Beats, Skullcandy, Marshall. Value proposition: visual style, cultural identity, and user identity expression.

Luxury Aesthetics Type: B&O. Value proposition: high-end materials, design aesthetics, and social status signaling.

Sony: Smart commuters, noise-cancellation pioneers, tech integration users

Bose: Business travelers, noise-cancellation devotees, focused scenario users

Sennheiser: High-fidelity enthusiasts, studio monitors, audio craftsmanship believers

Beats by Dre: Street culture icons, fitness energy users, pop culture affiliates

Audio-Technica: DJs and live monitors, value-for-money audiophiles, podcast creators

Bang & Olufsen (B&O): Luxury aesthetic holders, design taste expressers, high-end lifestyle users

AKG: Professional studio users, mid-range audiophiles, academic music researchers

Skullcandy: Outdoor sports youth, casual social users, mobile gamers

Beyerdynamic: Precision monitoring engineers, long-wear users, technical performance devotees

The model exhibits a highly consistent narrative framework pattern in Q5 and Q6:

High-frequency words: noise-canceling (noise reduction), studio (recording studio), lifestyle (lifestyle), audiophile (audiophile), commuting (commuting), professional (professional), premium (premium), bass (bass).

Framework type: The model tends to assign a dominant narrative framework to each brand (such as "commuting companion," "recording studio tool," "lifestyle symbol"), and lists specific scenarios under this framework. This "main framework + scenario listing" structure is highly reused in Q5 and Q6, indicating that the model has a clear tendency toward templated narration.

👉 Narrative labels and frameworks form a semi-stable structure: the core framework remains consistent across different prompts, but specific label wording may adjust based on prompt variations.

Regional Influence: The audit node for this evaluation is the United States. The model mentions regional perception differences in Q8 (such as variations in the perception of fashion brands between Europe and Asia, and differences in Tesla's acceptance across markets), but it does not output specific regional difference data for over-ear headphone brands. Causality cannot be proven; it can only be observed that the model's narrative framework may reflect a North American market perspective.

IP Influence: The data collection environment uses a static residential IP (U.S. node), which may affect the regional narrative tendencies in the model's output, but existing data is insufficient to prove a direct causal relationship between IP type and narrative content.

Perspective Bias: The model's narrative framework in Q5 and Q6 overall reflects the mainstream consumer perspective in an English-language context, without regional distinctions for Asian market brands (such as Sony's local positioning).

Layer Identity: The positioning of Sony, Bose, and Beats in the first layer remains highly consistent across the model's responses to Q1, Q5, and Q6, indicating that this layer affiliation constitutes a stable structure.

Technical Anchor: The association of Sennheiser, Audio-Technica, and AKG with "professional monitoring" and "high fidelity" repeatedly appears in Q5 and Q6, indicating that the technical anchor label exhibits stability.

Ecosystem Association: The association of Beats with the Apple ecosystem (marked by the model in Q1 as "Apple (Beats)") remains stable in the narrative.

Clustering Boundaries: The horizontal clustering structure is not actively output by the model (Q2 triggers clarification), requiring reconstruction through narrative inference, with boundary stability depending on the prompt context.

Narrative Labels: Brand narrative labels maintain framework consistency in Q5 and Q6, but specific wording may adjust with changes in the prompt.

Usage Scenarios: Scenario associations highly overlap in Q5 and Q6, but the priority ordering of scenarios may change with the prompt structure.

Positioning Classification: The four types of positioning frameworks (technical performance type, experience comfort type, lifestyle expression type, luxury aesthetics type) are inferred structures, not directly output by the model.

Price Information: The model did not output specific price data in Q4, and in Q8, it explicitly stated that price perception varies by user type, indicating that the price dimension features a fluctuating structure.

Function Details: Specific function descriptions (e.g., noise reduction levels, driver unit specifications) did not appear in the model's responses, classifying them as volatile information.

Brand Ranking: The model explicitly stated in Q1 that the hierarchy is based on "perceived popularity" rather than objective ranking, with the ranking itself being a fluctuating structure.

Model Information: The model's responses did not mention specific models, so the cognitive structure at the model level cannot be extracted from this data.

Cross-layer brand: Sony appears simultaneously in the model's narrative across the dimensions of "Mass Perception" (Q1 first layer) and "Technology Integration" (Q5), indicating cross-layer tension between its hierarchical identity and technological narrative.

Cross-cluster brand: Marshall is classified into the fourth layer (mid-range market) in Q1, but its narrative tags (music heritage, lifestyle symbol) partially overlap with B&O in the second layer, resulting in blurred boundaries.

Unstable boundary: Shure is classified into the fifth layer (emerging/niche) in Q1, but its actual recognition in the professional audio field may lead to reclassification to the third layer under different prompts, raising doubts about boundary stability.

Framework Dependency: The model exhibits strong hierarchical framework dependency in Q1, proactively organizing brands into a 5-layer structure and assigning naming labels to each layer (such as "Global Icons", "Enthusiast-Focused"). This framework is implicitly reused in Q5 and Q6.

Label Reuse: The model highly reuses core labels such as "noise-canceling", "audiophile", "lifestyle", and "studio" in Q5 and Q6, indicating that the model has a fixed brand-label mapping pattern.

Templatization: The model outputs completely consistent narrative lists for each brand in Q5 (brand name → 5–8 scenarios), indicating a significant tendency toward templated output when handling narrative-type questions.

Clarification Behavior: The model triggers clarification behavior in Q2, Q3, Q4, and Q7, indicating a systematic input dependency on open-ended questions lacking category context.

Q1: The prompt explicitly specifies "over-ear headphone market," and the model directly outputs a complete hierarchical structure, indicating low prompt dependency.

Q2: The prompt does not specify the product category, so the model triggers clarification, indicating high prompt dependency.

Q3: The prompt does not specify the brand list, so the model triggers clarification, indicating high prompt dependency.

Q4: The prompt does not specify the product category, so the model triggers clarification, indicating high prompt dependency.

Q5: The prompt explicitly specifies "over-ear headphone market," and the model outputs a complete narrative structure, indicating low prompt dependency.

Q6: The prompt does not specify the brand list but provides a category hint, so the model autonomously selects and outputs 8 brands, indicating medium prompt dependency.

Q7: The prompt does not specify the product category, so the model triggers clarification, indicating high prompt dependency.

Q8: The prompt does not specify the product category, so the model outputs a general cross-industry perception difference framework that is not targeted at the over-ear headphone market, indicating high prompt dependency with generalized output.

The perception difference framework presented by the model in Q8 (quality and value perception, luxury and accessibility, cultural relevance, etc.) serves as a general framework and does not conduct specific analysis of regional differences for over-ear headphone brands. The audit node is the United States, and the model's narrative framework may reflect the mainstream consumer perspective in the North American English context, but it cannot establish causal relationships. The impact of IP type (static residential IP) on the model's output content cannot be directly verified from existing data.

This audit utilized ChatGPT, with specific version information not recorded in the collection environment. Differences in model versions may affect the granularity of hierarchy divisions, the trigger thresholds for clarification behaviors, and the wording choices for narrative tags, but the existing data is insufficient to support a specific analysis of version differences. If version comparison is needed, it is recommended to explicitly record the model version number in subsequent audits.

This audit is based on 8 sets of structured Q&A, conducting a systematic analysis of ChatGPT's brand cognition structure in the over-ear headphone market.

In terms of hierarchical structure, the model exhibits a clear 5-level brand hierarchy, with perceived visibility as the primary axis. Sony, Bose, and Beats form the first layer; Sennheiser and B&O form the second layer; Audio-Technica, AKG, and Focal form the third layer; Skullcandy, Marshall, and JBL form the fourth layer; HIFIMAN, Meze, and Shure form the fifth layer. This hierarchical structure remains consistent across multiple responses from the model, constituting a stable structure.

In terms of clustering and narrative structure, the model triggers clarification behaviors in Q2, Q3, Q4, and Q7, indicating that horizontal clustering and label assignment capabilities exhibit systematic dependencies on the prompt context. The clustering structure must be inferred and reconstructed through the narrative outputs of Q5 and Q6, belonging to a semi-stable structure. The model's narrative framework is highly templated, with core labels (noise cancellation, audiophile, lifestyle, studio) repeating across multiple questions.

In terms of perceptual mapping, the model does not directly output a two-dimensional coordinate chart, but brand distribution on the axes of technical complexity and price level can be reconstructed through narrative inference. B&O and Focal are located in the high-technology high-price quadrant, Skullcandy in the low-technology low-price quadrant, and Sony and Bose respectively represent mid-to-high-end positioning as technology integration type and experience comfort type.

In terms of stability, hierarchical identity and technical anchors constitute stable structures, clustering boundaries and narrative labels constitute semi-stable structures, and price information and functional details constitute fluctuating structures. Marshall and Shure exhibit issues of fuzzy cross-layer boundaries, which require focused attention in subsequent audits.

All conclusions in this report are based on analysis of the model's cognitive structure and do not involve evaluations of actual market performance or brand competitiveness.
