2 change(s): 2 moderate | Durability score reflects multiple reports of premature battery degradation (unusable after 1+ year), transparency mode failures requiring service center visits, and poor quality ear tips. Material quality affected by reported fit/comfort issues and durability complaints despite premium positioning. Brand reputation remains moderate due to Sony's overall standing but diminished by firmware lock-in practices, involuntary tuning changes, and quality control issues reported across multiple users. The earbud is well-regarded for audio quality when functioning, which moderates the scores, but reliability and consumer-friendly practices are concerns.
