苹果公司创始人史蒂夫·乔布斯最爱的品牌之一，同时也是Denmark皇室的御用品牌。B&O的产品外观设计出色，深受包豪斯实用主义影响，至今共有超过10件产品被美国纽约现代艺术博物馆列为永久性设计收藏展品。其产品用料上乘，Bluetooth headset均采用小羊皮等高级材料，但也许是出于美观方面的考虑，B&O的头戴earphone都不可折叠，便携性较低。
 
B&O的产品不仅拥有出色的外观设计，音质也达到一流水准，其H4在美国《消费者报告》中获得76分，排名同类型产品第一。声音方面，H4的低频下潜和弹性比较一般，中频人声靠前，厚度适中，高频没有过多惊艳表现，延伸一般，声音悦耳但不刺耳，声场大且宽松，适合小编制类流行曲目。
 
但2298元的H4只是B&O入门级产品，H9i才是真正旗舰，入选知名媒体Wired的最佳无线earphone榜单，H9i的基本版H9也被The Verge评为最佳无线earphone。H9i售价为3898元，拥有IP54防护等级，这在主打音乐的头戴式earphone中相当少见。并且其电池可更换，同类型的其它品牌earphone也不具备这一功能，23小时的续航则处于中上水平。H9i加入可调节强弱的降噪功能，采用更方便的Type-C数据接口，支持AAC蓝牙编码。其拥有广阔的声场，出色的解析力和低频量感在蓝牙earphone中非常出挑，中频人声靠后，乐器声有明显的层次感，整体表现堪称优秀。
 
H9The price is also 3898 yuan, but its battery life and sound quality are slightly inferior to H9i, the noise reduction effect cannot be adjusted, and the protection level and battery replacement are not supported. The only thing that H9 is stronger than H9i is that it supports aptX and AAC advanced Bluetooth encoding.
 
H9i and H9 both use over-ear earmuffs, and the 3198 yuan H8i and 3798 yuan H8 can be regarded as the on-ear versions of the two, respectively, and the functional characteristics are mostly the same, but the battery life of H8i 45 hours (noise cancellation off) has reached the top level in its class. H7On the basis of H9, the noise reduction function has been canceled, and all performances are at the mainstream level, and the price is 2998 yuan.
