The Poly - Plantronics Discovery 975SE/R are wireless headphones that allow unrestricted movement and thus increase comfort while listening to music. Because of this feature wireless headphones are especially popular with casual users. On the other hand, the limiting factor of wireless headphones is a certain delay in sound transmission between the source and the headphones (almost indistinguishable for the average user), and they also need to be charged regularly. Unlike wired headphones, where the headphones are charged by the connected cable itself, wireless ones must be charged separately. The technology used for the sound transmission used by the headphones is Bluetooth 2.1 EDR.
These headphones are in-ear type and are therefore designed to fit directly into the ear. This allows them complete or at least partial isolation from external noise. Such headphones may also have an ambient sound isolation function, which affects the degree of their isolation capabilities. Compared to over-the-head headphones, in-ear headphones are much more portable The weight of the headphones is 8 g.

In terms of headphone battery life as a significant factor in the purchase decision, it depends on what you want to use the headphones for and potentially how often you will be able to recharge them. Headphones with up to a few hours of battery life are more suitable for home use as they will require more frequent charging. Headphones with a battery life of around 10 hours or more are already more suitable for commuting and shorter journeys. However, nowadays you can also find headphones on the market that have a battery life in the higher tens to hundreds of hours. In this case, you do not have to worry about your headphones simply running out of power on longer journeys, and you will not have to deal with constant recharging. The battery life of the Poly - Plantronics Discovery 975SE/R reaches up to 5 hour(s).
The standby battery life quoted by the manufacturer is 168 hours.
