According to a 2017 survey by Statista, Bose tied with Sony for the first place in brand awareness in the U.S. market. However, Bose is more known for its benchmark noise-canceling headphones, and does not have Bluetooth earbuds that focus on sound quality, and the 4 Bluetooth earbuds on sale, SoundSport Wireless, SoundSport Pulse, and SoundSport Free are all sports headphones, and the QC30 is noise-canceling headphones. In addition, none of the Bose Bluetooth headphones support aptX or AAC Bluetooth encoding.
 
But the lack of support for aptX or AAC Bluetooth encoding doesn't mean there isn't a lot of good sound quality, and the Bose SoundSport Wireless scored 76 points in the U.S. Consumer Reports, ranking it joint second in its class with headphones like the NuForce BE6i. Its price is 1388 yuan, with a back-hanging design, and the addition of Bose's well-received shark fin rubber plug, which is firm to wear and has a low sense of presence, but the disadvantage is that it is easy to be damaged. However, the SoundSport Wireless has only 6 hours of battery life, which is not outstanding compared to similar products. In terms of sound, SoundSport Wireless does not emphasize low frequencies like ordinary sports headphones, its three frequencies are relatively balanced, and the sound field is relatively open, which does not give people a very stuffy feeling.
 
The SoundSport Pulse is the same as the SoundSport Wireless, with the only difference being that the former includes heart rate monitoring, which gives it a battery life of just 5 hours. However, the price of SoundSport Pulse is as high as 1788 yuan, and the product premium is higher.
 
The SoundSport Free, priced at 1,998 yuan, scored 71 points in the U.S. Consumer Reports, ranking third in its category. In the comparison of 24 Bluetooth earbuds by the Hong Kong Consumer Council, it is one of the six earbuds with the best sound quality, and the sound quality sub-category is rated 4 stars, tied with headphones such as the Sony WI-1000X. It can be said that SoundSport Free is one of the most worthwhile split Bluetooth headphones on the market, not only has excellent sound quality, but also has a 5-hour battery life compared to other split headphones.
 
For consumers who pay attention to sound quality, the QC30, which focuses on noise reduction, is not recommended to buy, and many users say that its sound quality is poor, and it is more suitable for consumers who pursue wearing comfort and noise reduction, with a price of 2498 yuan.
