An increasing number of devices have the capability to control phone calls and media playback as well as transmit stereo audio via Bluetooth, creating an increased demand for stereo Bluetooth headphones and headsets. The MEElectronics Air-Fi range of products, consisting of the AF32 stereo Bluetooth headphone with mic and the AF9 stereo Bluetooth headset, meet that demand while delivering the sound quality people have come to expect from MEElectronics. Most of these devices are equipped with A2DP Bluetooth, which allows the new Air-Fi line of Bluetooth products from MEElectronics to offer stereo audio, media controls, and phone functionality without the inconvenience of wires. Extensive research and development went into tuning the sound, resulting in unprecedented audio quality for a Bluetooth headphone and headset. The AF9 headset is based on the award-winning M9 earphones, offering great bass and clarity wirelessly with a stereo Bluetooth receiver.
