Recommended model: PX
 
宝华韦健（B&W），是United Kingdom顶级音响品牌，也是音响发烧友心目中的殿堂级品牌。其鹦鹉螺扬声器被誉为“世上金钱能买到的最佳扬声器”，以干净、无杂质、零渲染的声音再现效果而闻名于世。其实在音响界也有一个“3B”品牌的说法，其中就包括B&W，音质过硬但外观设计常常跑偏就是B&W的最大特点。
 
在众多降噪earphone中，如果单论音质的话，B&W的earphone绝对能处于第一梯队。PX是B&W的第一款降噪earphone，它所使用的是自家旗舰P9上的单元和声学技术，而P9的官方售价近7000元，PX仅为它的一半，单单是发声单元的配置，PX就显得十分豪华。
 
In terms of noise reduction, PX provides three noise reduction modes for users to choose, namely office, city, and flight, and the intensity changes from weak to strong, which is enough to cope with daily use, but in the suppression of high-frequency noise, such as the honking of cars, sudden braking, building decoration sounds, children's screams, etc., PX is far away from BOSE and SONY. In terms of battery life, the battery life is about 22 hours, and there is not much pressure for 2-3 days of daily use. In terms of materials, PX uses metal with better integration, with the outer layer of bulletproof nylon fabric, the overall texture is very good, and the only defect is that the wearing comfort is poor. The PX's ear cups are thin, the padding is insufficient, and the head bridge is stiff, which makes it difficult to wear for a long time.
 
In addition, it should be noted that PX is different from mainstream wireless noise cancelling headphones, even in wired mode, it still needs power to work, which means that PX cannot be used as ordinary wired headphones when the battery is dead.
