1. An audio transmitting/receiving system for manipulating audio signals, comprising:
- a first wireless earbud comprising;
an elongated portion that has a length from a distal end to a proximate end of the elongated portion in a range of 1.25-1.75 inches;
a projecting portion extending from said elongated portion at said proximate end of the first wireless earbud in a direction substantially perpendicular to the elongated portion, wherein said projecting portion includes a first speaker housing that includes a first audio speaker, the first audio speaker acoustically isolated from a first integrated array of microphones, wherein;
said first integrated array of microphones includes a first microphone located at the distal end of the first wireless earbud and a second microphone located at the proximate end and immediately adjacent to the first speaker housing of the first wireless earbud; and
said first integrated array of microphones is oriented along a first axis that creates a first reception beam angle pointed forward from a user'"'"'s ear to the user'"'"'s mouth;
at least one signal processor for collecting and processing said audio signals corresponding to sound sensed by the first integrated array of microphones, the at least one signal processor configured to;
apply a beamforming algorithm to said audio signals corresponding to sound sensed by the first integrated array of microphones;
selectively apply an adaptive filter to reduce background noise sensed from the beamformed audio signals or said audio signals by the first integrated array of microphones; and
selectively transmit the beamformed audio signals;
a display that is configured to display a graphical user interface (GUI) for selecting audio options; and
a BLUETOOTH wireless transmitter/receiver for communicating with one or more other devices.

Abstract
The invention relates to an audio device for use proximate a user'"'"'s ears. The audio device includes first and second audio transmitting/receiving devices that are capable of operating in stereo. The audio device may be used within a system for manipulating audio signals received by the device. The manipulation may include processing received audio signals to enhance their quality. The processing may include applying one or more audio enhancement algorithms such as beamforming, active noise reduction, etc. A corresponding method for manipulating audio signals is also disclosed.
