meron akong noise-cancelling headphone. Kaya lang simula nang masira yung foam ng earpad nya eh parang nabawasan na yung bass nya. okay naman, effective sya pag constant yung noise level. Pero masakit sa tenga pag hinahabol nyang i-cancel yung busina ng mga bus. Yung ugong ng makina kaya. Tapos pag tinatamaan ng hangin galing sa electric fan yung earphone eh cinocompensate din nung noise cancelling circuit yung wind noise. Para tuloy may flanger/phaser yung music material mo

Lately, the in-ear earphones are doing similar and/or better job. May background hiss yung noise-cancelling headphone, usually kailangan ko magpatugtog para ma-mask yun. And wierd yung feelnig parang naka-on yung noise cancelling effect nang walang music.

Mas cheap pa din yung in-ear , IMHO

IMHO, wala pang perfect noise cancelling cicuit. Effectiveness nya ay limitted sa continous and slow changing sounds. Pero sa speech useless sya. So, bali wala yan sa mga nagger.
