Poly Calisto 5300 USB-A with BT600 Dongle

The chemical composition or classification of a battery, such as lithium‑ion, lithium‑polymer, nickel‑metal hydride, sealed lead acid, alkaline, zinc‑air, etc. It indicates the type of electrochemical reaction that stores and delivers energy in the device.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The network and data interface technologies supported by the product, such as Wired, Wireless, USB, Bluetooth, or combinations thereof. Each value represents a distinct technology that can be used for communication or power delivery.

The general classification of a product, such as tablet, smartphone, router, or computer. It indicates the primary function or form factor that helps buyers quickly identify and compare similar items.

The span of frequencies, expressed in hertz (Hz), that a device can operate within or respond to. It may be given as a single value, a numeric range (e.g., "20 000‑50 000 Hz"), or an open‑ended interval such as "2.4 GHz+" indicating the lower bound only.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

The impedance value indicates the resistance that a component or circuit offers to alternating current, expressed in ohms (Ω). It is used to characterize speakers, microphones, audio cables and other electronic equipment to ensure optimal compatibility with the source signal.

The span of audible frequencies that a microphone can accurately capture, expressed as a minimum and maximum value in hertz (Hz). It indicates the lowest and highest tones the device can reproduce or record, helping users assess suitability for different audio applications.

The main electrical supply that powers the device, such as mains electricity (AC), battery, USB power, PoE, or a combination of these options.

Indicates whether the device has a built‑in speakerphone function that allows hands‑free voice communication without using external headsets or microphones.

The type(s) of USB connector(s) present on a device, such as Micro‑USB, USB Type‑C, USB Type‑A, or combinations thereof. This attribute indicates the physical ports that can be used for data transfer, charging, or peripheral connectivity.
