The specific version of the Bluetooth standard supported by a product, expressed as a numeric value (e.g., 4.2, 5.0) or with additional descriptors such as "+HS" or feature lists. This attribute indicates the capabilities and compatibility for wireless communication.

A list of official certifications or compliance marks that the product has received from regulatory bodies, safety organizations, or industry standards groups. Each entry represents a distinct certification such as CE, FCC, RoHS, UL, or WEEE, and may include additional details like version numbers or specific test reports.

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 country where the product was manufactured or its primary geographic source. This attribute indicates the nation responsible for the production or assembly of the item.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

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 vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

Indica el material o la combinación de materiales con los que está fabricado el componente más importante de un producto, como metal, plástico, vidrio u otros compuestos. Este atributo ayuda a comprender la durabilidad, peso y estética del artículo.

Indicates whether the product has a line‑in input, i.e., a port that accepts analog audio signals from external sources such as microphones or other devices. A value of "Yes" means the input is present; "No" means it is not.

The total count of individual satellite speaker units included in a sound system or audio setup. It indicates how many separate satellite speakers are present, allowing users to assess the size and coverage of the audio configuration.

The type of electrical supply that powers the device, such as mains electricity, batteries, USB power, or a combination of these options.

A brief statement of the intended or most suitable use cases for a product, such as the type of environment (indoor, outdoor), activity (gaming, office work, music listening) or general application category. It helps customers quickly determine whether the item fits their needs.

The root‑mean‑square (RMS) power rating of a device, expressed in watts (W). It represents the average electrical power that the product can deliver or consume under normal operating conditions.

The range of audible frequencies that a speaker or speaker system can reproduce accurately, expressed in hertz (Hz). It indicates the lowest and highest tones the device can produce, helping users assess audio performance for music, movies, and other sound applications.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.

Indicates whether the product meets environmental and sustainability standards, such as reduced hazardous substances, energy efficiency, or other green certifications.

The overall distortion introduced by a device, expressed as a percentage of the total output signal. It represents the ratio of all harmonic components to the fundamental frequency and indicates how much the waveform deviates from a perfect sine wave.

The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.
