Poly - Plantronics SupraPlus Wireless CS351N/A Specifications, Tests and Review

The wireless headphones Poly - Plantronics SupraPlus Wireless CS351N/A allow unrestricted movement, which increases the comfort of using the headphones. This feature is particularly popular with headphones for casual use. However, a certain limiting factor of wireless headphones compared to wired ones is a certain delay in sound transmission between the source and the headphones (but almost indistinguishable for the average user) and the need for regular charging. Unlike wired headphones, wireless headphones are charged separately. The maximum range of the headphones is up to 100 m. This range represents the distance from the sound source at which the headphones with wireless sound transmission can be used. However, the maximum range may be affected by obstacles such as walls or people, etc.

The headphones are designed as on-ear. On-ear headphones are generally lighter. However, their design has fewer isolation capabilities, and therefore, for example, more sound can be let in and out compared to around-ear headphones. The weight of the headphones is 66 g.

The sound quality can be affected by many factors.

Poly - Plantronics SupraPlus Wireless CS351N/A has a boom–type microphone.

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 SupraPlus Wireless CS351N/A reaches up to 9 hour(s).

The standby battery life quoted by the manufacturer is 50 hours.
