• intros：{"brand_intro":"飞傲（FiiO）成立于2007年，是中国领先的便携音频设备制造商，总部位于广州。创始人梁伟明原是音响工程师，因对随身听音质不满而创立品牌。飞傲以\"让音乐更动听\"为使命，坚持自主研发与高性价比路线，在解码耳放、播放器领域拥有多项专利。其品控体系通过ISO9001认证，每台设备出厂前需经过48小时老化测试。KA5是其2023年推出的爆款，凭借双DAC架构和强劲推力，迅速成为千元内监听耳放标杆。","product_intro":"KA5定位为专业级便携解码耳放，专为录音棚监听、HiFi发烧友及游戏玩家设计。核心卖点包括双ESS ES9219C DAC芯片、768kHz/32bit解码能力、4.4mm平衡输出（320mW@32Ω）以及独立音量旋钮。相比同价位竞品（如山灵UA5），KA5在解析力和动态范围上更胜一筹，且支持UAC 1.0/2.0双模式，兼容PC、手机、Switch等设备。适合需要高保真监听、低延迟音频回放的专业用户。","key_specs":{"DAC芯片":"双ESS ES9219C，支持原生DSD512和PCM768kHz/32bit","输出功率":"平衡输出320mW@32Ω，单端输出125mW@32Ω","信噪比":"≥123dB（A计权），底噪极低","接口":"3.5mm单端 + 4.4mm平衡，USB-C输入","重量":"约28g，便携铝合金机身"}}
