Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
Devices with a subwoofer have a higher quality, deeper bass.
Audio output power is based on the number of speakers and their power in watts. High audio output power results in loud, clear sounds.
The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
Signal-to-noise ratio is a measure that compares the level of a desired signal (meaningful information) to the level of background noise (unwanted signal), the bigger the less perceived noise.
More microphones result in better sound quality and enable the device to filter out background noise.
