The first and second regions together define an interior surface shaped to couple the cushion to acoustic elements of an earphone. The first material occupies a first volume adjacent to the interior surface. The second material occupies a second volume between the first material and the first and second outer surfaces. The first and second materials are of different hardnesses. | 09-01-2011 |

20120252541 | Wireless Audio Device Call Device Selection - A wireless two-way communications headset is able to enter into a partial power mode in which a latching or non-momentary power switch has been operated to an “on” state, but in which there has been a lack of user operation of the headset for more than a predetermined period of time, and in this partial power mode, a processing device of the headset monitors manually-operable controls for an indication of their being operated by a user in a manner indicating a user's intent to engage in audio communications. In response to this indication, the headset enters a higher power mode in which a wireless link with another wireless device is formed and then performs the function intended by the user. In being operated by a user to initiate audio communications with another wireless device (e.g., making a telephone call), the wireless headset first attempts to do so with the wireless device with which the wireless headset most recently engaged in audio communications, and failing that, the wireless headset then attempts to do so with second-most recent wireless device with which the wireless headset engaged in audio communications. | 10-04-2012 |
20130095884 | SOURCE DEPENDENT WIRELESS EARPIECE EQUALIZING - A headphone for use with a wireless audio device. The headphone determines whether the origin of an incoming transmission is a cell phone or a device such as a land line device or a computer. The headphone applies a different equalization pattern depending on whether the origin is a land line device or a computer or whether the origin is a cell phone. The headphone may measure the amplitude of the incoming transmission above a first threshold frequency, or below a second threshold frequency, or both to determine if the origin is a land line device or a computer or if the origin is a cell phone. | 04-18-2013 |
