Sandberg HydroGuard Waterproof Bluetooth Earphones

The total amount of electrical energy a battery can store, expressed as a numeric value with an appropriate unit such as mAh or Ah. It indicates how long the device can operate between charges and allows users to compare power supplies across products.

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 chemical composition or classification of a battery, such as alkaline, lithium‑ion, NiMH, or lead‑acid. It indicates the energy storage technology used in the product and helps users identify compatibility with devices that require specific battery chemistries.

The specific version of the Bluetooth standard supported by the product, indicating its capabilities for wireless communication and compatibility with other devices. Values may be numeric (e.g., 4.2, 5.0) or include additional descriptors such as "+HS" or feature lists.

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 total duration a device can play audio continuously without interruption, expressed in standard time units such as minutes or hours. This value indicates the maximum autonomous listening period available on a single charge or power source.

The physical dimension of the driver’s diaphragm or cone in a speaker or headphone. It is expressed as a linear measurement (e.g., millimetres, centimetres, inches) and allows users to compare the relative size of drivers across different products.

The type of ear attachment used by a headset or earphones, indicating how the device fits around or inside the ear. Common values include "Intraaural", "Circumaural", "Supraaural" and "On‑ear". This attribute helps users choose a model that matches their preferred fit and comfort.

The operating frequency range of a device expressed in hertz (Hz). It indicates the specific radio frequencies that the product can transmit or receive, whether as a single value (e.g., 2.4 GHz) or a range (e.g., 2.4–5 GHz). This attribute helps users understand the wireless capabilities and compatibility of the device with network standards.

The span of audio frequencies that a product can accurately reproduce or respond to, expressed in hertz (Hz). It indicates the lowest and highest frequencies the device can handle, helping users assess suitability for music playback, communication, or signal processing applications.

The general classification of a headset based on how it delivers audio to the user, such as binaural (two‑channel), monaural (single‑channel), or other configurations. This attribute helps buyers understand whether the device provides stereo sound, single‑speaker output, or specialized listening modes.

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 electrical impedance presented by a microphone input, expressed in ohms (Ω). It indicates the resistance that the input circuit offers to alternating current signals, affecting signal level and compatibility with microphones.

The acoustic sensitivity of a microphone, expressed in decibels (dB). It indicates how effectively the microphone converts sound pressure into an electrical signal; lower (more negative) values mean higher sensitivity and better performance at low sound levels.

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

The vertical dimension of a product’s packaging measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and helps customers assess how tall the package will be when stored or shipped.

Indicates the general classification or type of an item, such as "laptop", "projector", "router" or "paint". It helps users quickly identify the nature of the product and compare similar items across categories.

A comma‑separated list of protective characteristics that a product offers, such as resistance to dust, water, shock, heat, or other environmental factors.

Indicates whether the product contains a battery. A value of true means the device has an internal or removable battery, while false indicates it does not.

The total duration a device can remain powered on while not actively in use before it automatically powers off or enters low‑power mode. It is expressed in standard time units such as hours, minutes, or days and applies to batteries, chargers, and other electronic components that support standby operation.

A textual description of the way a product is worn or fitted on the body, such as "headband", "earhook", "neck‑band", "over‑the‑ear", or "in‑ear". This attribute helps users understand how the item will be positioned and secured during use.

The maximum distance over which a device can maintain a reliable wireless connection to another device or network. It is expressed in linear units such as meters or feet and indicates the effective coverage area for Wi‑Fi, Bluetooth, RF, or other radio technologies.
