When used as a Loudspeaker, for your day to day music the frequency response of the Poly Sync 20 is 80 Hz to 20 kHz, the low end on the frequency spectrum between 20Hz to 80Hz is ideal for music but lacking on this unit .
To give a comparison Amazon Alexa has a frequency range of 30Hz to 24kHz while it does not have the features on this multi unit kit . Overall the lower frequency is only observed by an avid music fan, but not pronounced on its primary use of a conference speaker / mic kit .
The unit is a multipurpose speaker, conference unit which as expected from the Poly brand ( Previously Plantronics) has great audio and ease of use in connection. This unit came with minimum fuss in terms of accessories , carry case, USB dongle , carry strap with a hardwired USB cable resulting in a universal kit option for hybrid use in any environment . The features in terms of MS teams approved, various colours, red on mute , green in use or light bar to view the volume level is practical in any meeting. The kit has been used in noisy environments with industrial machinery in the background and again the background was suppressed ensuring the conversations and accents were heard no matter where sitting in the room. The portable option to fit into a Laptop bag and carrier around gave additional convenience in the use of this speaker. This is a kit which is highly recommended in terms of ease of use, portability , multipurpose options , from a known quality brand, hard to fault this kit.
