Plain-English explanations for every spec term you encounter when comparing products.
What is Refresh Rate?
Refresh rate is the number of times per second a display updates its image, measured in Hertz (Hz). A higher refresh rate produces smoother motion on screen.
What is Display Resolution?
Display resolution is the total number of pixels on a screen, expressed as width by height (for example 1920 by 1080). Higher resolution means a sharper and more detailed image.
What is Active Noise Cancellation (ANC)?
Active Noise Cancellation (ANC) uses built-in microphones to detect ambient sound and generates an opposing sound wave to cancel it out, reducing background noise reaching your ears.
What is a Bluetooth Audio Codec?
A Bluetooth audio codec is the algorithm used to compress and transmit audio wirelessly. Higher-quality codecs like LDAC and aptX HD enable near-lossless sound over Bluetooth.
What is Battery Capacity (mAh)?
Battery capacity in milliampere-hours (mAh) measures how much electrical charge a battery holds. A higher mAh rating generally means longer battery life, though real-world endurance depends on many factors.
What is Charging Speed (Watts)?
Charging speed in watts (W) indicates how fast a charger delivers power to a battery. Higher wattage means shorter charging times.
