Unverified预算有限只买入门降噪（低频衰减<25dB）意义不大：低端降噪对地铁/飞机噪音削弱有限，反而可能有底噪，此预算不如买被动隔音好的密封入耳式89% similarUnverified预算有限（入门价位）不建议为'主动降噪'功能买单，低端ANC降噪效果弱且易引入底噪，同价位物理隔音好的封闭式或深入耳设计实际隔音可能更强88% similarUnverified低价降噪头戴（百元档）多为单馈降噪，只能压制持续低频噪音，对突发噪音和人声无效，且常伴随明显底噪和音质塌陷；预算有限追求降噪不如选中端降噪入耳87% similarUnverified价格低廉、操作极简（物理旋钮调音量），但放大噪音与目标声音不加区分，嘈杂环境下体验较差83% similarUnverified预算有限追求音质纯听歌者不建议买入门级降噪耳机，同价位半开放/有线产品音质更好；入门降噪档降噪能力弱且音质妥协大83% similar
