Since its inception, Plantronics has been deeply involved in the field of Bluetooth transmission, and its products are not only the first choice of the New York Stock Exchange, but also used in the Apollo moon landing in the United States in 1969. In 2018, Plantronics acquired Polyton, a giant in the video conferencing equipment industry, for $2 billion, further establishing its leading position in the field of professional consumer voice communication products.
 
Thanks to the accumulation of Bluetooth transmission technology, Plantronics headphones have outstanding connectivity performance, Bluetooth versions are 4.0 and above, can connect to 2 devices at the same time, and each pair of headphones supports mobile APP, with a wealth of additional functions. One of the best purchases is the BackBeat PRO 2, which was named the best wireless headphones of 2018 by CNET, Wired, and techradar, respectively.
 
Wired considers the BackBeat PRO 2 to be the most comfortable and feature-rich headphones for its price point (1498 yuan). BackBeat PRO 2's mobile app includes over-the-air (OTA) updates, personalized definitions, meeting management, and lost and recovered features, while other headsets often only have one or two of these features. BackBeat PRO 2 also adds noise cancellation and ambient sound modes, and while the experience isn't as impressive as the Bose QC35 and Sony WH-1000XM3, it's about half the price. In addition, it uses a rare Type 1 Bluetooth connectivity standard, with a transmission distance of more than 100 meters and an above-average battery life of 24 hours.
 
In terms of sound, the BackBeat PRO 2 supports aptX and AAC Bluetooth encoding, and the low frequencies are tight and refreshing, while the midrange is bright and clear but a little thin, and the high frequencies are a little harsh. BackBeat PRO 2 also provides SE version, which differs from the ordinary version in that it adds NFC function and comes with a storage box (the ordinary version is a dust bag), priced at 1998 yuan.
 
The 398 yuan BackBeat Sense is another cost-effective choice for Plantronics, ranking joint third in the category with a score of 66 in the U.S. Consumer Reports. Its 140g weight is the lightest Bluetooth headset, and it also uses the Type 1 Bluetooth connectivity standard, and also adds an ambient sound mode that is not available in the same price range, and supports aptX and AAC Bluetooth encoding. Consumer Reports commented that BackBeat Sense is "strong and bouncy in the low end, but slightly prominent, fairly uniform in the midrange, with some visible grain and glitches, a softer high end and a small soundstage". The disadvantage is that the 18-hour battery life is at the middle and lower level, and the earphones are not foldable, so the storage is not very convenient.
 
Also worth buying is the VOYAGER 8200 UC, which is priced at 2999 yuan. Its index parameters are basically the same as those of BackBeat PRO 2 SE, the highlight is the addition of 4 DSP/MA noise-canceling microphones, the call is very clear, and the BT600 Bluetooth adapter supports enterprise-level VoIP phones, which has a strong business flavor. Plantronics also has three headphones, the BackBeat Go 810, the BackBeat Go 605 and the BACKBEAT 505, but they lack highlights and the sound quality is relatively average, so they are not worth buying.
