The consumer audio market never seems to diminish in popularity. For decades, consumers have used everything from a vintage Sony Walkman in the 80s to Apple AirPods and other sophisticated earbuds on the market today.
With the advent of media streaming, earbuds and headphones have become nearly ubiquitous among consumers that use these devices to watch Netflix, YouTube and TikTok. Oh, and they still listen to music.
The Plantronics Voyager Surround 85 is a wireless Bluetooth headset that is designed to be worn all day if necessary and allows the users to be immersed through its active noise cancellation. While in the office this might be an issue, but in the gym or on a run it could be a boon for the user.
In fact, the company claims the headset is good for loud offices or noisy environments due to its ACN capabilities.
