Signal-to-Noise Ratio (SNR):This is the ratio of signal intensity to noise intensity.
85 dB
Total Harmonic Distortion (THD):Total harmonic distortion is a measure of non-linear harmonic\n\ndistortion and is given in %. Non-linear harmonic distortions are\n\nsignals which were not present in the original before the signal was\n\nconverted by the headphones. These unwanted signals are caused by the\n\ndiaphragm, whose movements do not precisely move in time with the\n\nelectric signals that cause it to move. Unfortunately, this is a\n\nfeature of all electroacoustic transducers. Although it cannot be\n\ncompletely eliminated, suitable steps can be taken to minimise it.\n\nHowever, the user is not interested in why this distortion takes place\n\nbut in how great the level of distortion must be for it to become\n\nperceptible. According to the findings of several research projects, a\n\ntotal harmonic distortion of 1% in the frequency range of 100 to 2000\n\nHz is imperceptible. Below 100 Hz, the perceptibility threshold lies\n\nat 10%.

Plug and Play:Indicates whether this product supports is "plug and play". Plug and play is hardware or software that, after being installed ("plugged in"), can immediately be used ("played with"), as opposed to hardware or software which requires configuration.
FM radio:Frequency-modulated (FM) radio gives the clearest reception of any radio band. When used with a headset, it delivers stereo-like sound.
Built-in microphone:Microphone that is found inside the product.
Compatible memory cards:Types of memory cards which can be used with this product.
MicroSD (TransFlash)
Card reader integrated:The device includes a card reader e.g. a card reader in the disk bay of a computer or thin client to permit log-on using smart/pin cards.
Recommended usage:What the product should be used for, and how it should be used (e.g. ambient temperature).

Bluetooth:Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.
Wi-Fi:Popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio waves.
Connectivity technology:
Wired & Wireless
