Bose is well-known in the audio industry and is one of the world's oldest and largest speaker manufacturers in the United States. Its products are widely used in luxury car brands such as Rolls-Royce and Ferrari and in the field of aerospace technology, and it has also created a precedent for active noise cancelling headphones, which are regarded as industry benchmarks. Although Bose's sports headphones are not updated often, they have consistently ranked at the top of various reviews, and the reliability of the products is higher than that of brands such as Jaybird.
 
Prior to the launch of SoundSport Free, there were only three sports headphones available at Bose, all around 2016.
 
The performance of the four current Bose sports headphones is basically the same, the difference is that the SoundSport is the basic version, which uses a wired design; The SoundSport Wireless is a Bluetooth NFC version; The SoundSport Pulse adds a heart rate sensor to the Wireless. The SoundSport Free is a split Bluetooth headset.
 
The SoundSport Wireless is the best of the four headphones to buy, and it is also the most recommended sports headphones by various review agencies and media. In the U.S. Consumer Reports, SoundSport Wireless won the first place in its class with a score of 76, and was the winner of the sports headphones of the VGP2018 SUMMER, Japan's authoritative image awards, and also won the crown of the 2018 Best Sports Headphones by CNET.
 
The price of SoundSport Wireless is 1388 yuan, and it adds the brand's killer feature - "shark fin" rubber stopper. Compared to other brands, Bose's "shark fin" plug is the best wearing experience, not only is it securely secure, but the plug is extremely soft, with little presence on the ear, but it is too soft and relatively easy to break. The SoundSport Wireless has a battery life of 6 hours, and it only supports life waterproofing, and the performance is not outstanding. In addition, the cable does not have a tightening device like other brands, and only a clip is added to secure it. SoundSport Wireless does not support aptX or AAC Bluetooth encoding, but the sound quality is not bad, unlike the general sports headphones that emphasize low frequencies, and the three frequencies are relatively balanced; The soundstage is also relatively open, so it doesn't feel stuffy.
 
The Bose SoundSport Free also had a good rating, ranking second in its category with a score of 71 in Consumer Reports, ranking fifth in CNET's 2018 Best Sports Headphones, and winning the Editor's Choice Award for Best Running Headphones in PCMag. The price of SoundSport Free is 1998 yuan, and the shark fin is also added to increase the wearing firmness, and the weight of 15g will not become a burden to wear. Its 5-hour battery life is in the upper middle of its class, and the case can provide 10 hours of power, but the case is slightly larger than other headphones, and the headphones are only IPX4 waterproof. Considering the small size and easy loss of split Bluetooth headphones, Bose has also added an anti-loss feature to SoundSport Free, which allows you to see where the headphones last appeared through the mobile app.
 
In terms of sound quality, SoundSport Free also does not use aptX or AAC Bluetooth encoding, and its main performance is low and mid, while the processing of medium and high frequencies is not delicate enough, and the detail performance and resolution need to be improved. In addition, the problem of signal delay and instability of split Bluetooth headphones also occasionally occurs on the SoundSport Free, but it is already a better one except for the AirPods.
