Headphone providing fully natural interface are described. According to one aspect of such headphones, the headphones comprises a microphone configured for capturing an ambient sound, a speaker configured for playing audio signals, a command interface configured for receiving one or more external control commands, and a control unit having an ambient sound monitoring function. The control unit captures the ambient sound through the microphone, and automatically causes the headphones to enter an interactive mode when a preset interested sound is detected to appear in the ambient sound. The control unit controls the headphones to output an interactive reminder in the interactive mode, and the interactive reminder comprises one or more of visual reminders, a tactile reminder and an auditory reminder. Thus, interaction between the user and the ambience can be realized in a fully natural interface manner according to user preferences.

Techniques pertaining to an adaptive/configurable IF wireless receiver are disclosed. Such an adaptive/configurable IF wireless receiver can be used in a Bluetooth device. According to one embodiment of the present invention, a wireless receiver is designed to include a low noise amplifier configured to amplify an input RF signal; an adjustable local RF synthesizer configured to provide a local RF clock signal with variable frequency; a RF mixer configured to down convert the amplified RF signal to an analog IF signal by mixing the local RF clock signal with the amplified RF signal; a filter configured to filter the analog IF signal; an analog to digital converter configured to convert the filtered analog IF signal to a digital IF signal; an adjustable digital local IF synthesizer configured to provide a digital local IF clock signal with variable frequency; a digital mixer configured to down convert the digital IF signal to a baseband signal by mixing the digital local IF clock signal with the digital IF signal; and an IF configuration unit provided to configure the adjustable local RF synthesizer to vary the frequency of the local RF clock signal, and configure the adjustable digital local IF synthesizer to vary the frequency of the digital local IF clock signal.

Techniques for controlling a personalized Bluetooth device (e.g., headset) and a voice interaction control method thereof are described. According to one aspect of the present invention, the Bluetooth device is caused to maintain a voice contact list. Each item in the voice contact list corresponds to a phone number associated with a set of audio data (e.g., a voice or a predefined audio). Instead of dialing a phone number on a calling device (e.g., a cellular phone) being paired with the Bluetooth device, a user can speak to the Bluetooth device that is caused to search a corresponding phone number in the voice contact list. The number is then sent to the calling device to make a call.

Techniques for a personalized Bluetooth headset and a voice interaction control method thereof are described. According to one aspect of the present invention, the Bluetooth headset is caused to maintain a voice contact list. Each item in the voice contact list corresponds to a phone number associated with a set of audio data (e.g., a voice or a predefined audio). When a paired mobile device receives a call, the voice contact list is searched per the caller number. A corresponding audio is played back when an item is located in the voice contact list. As such a user of the Bluetooth headset knows who is calling and determines whether the call shall be answered or not.
