Panasonic has released firmware update programs for the RZ-S500W and RZ-S300W, two recently-launched wireless headphones, along with an application to improve their functions and usability. 

The firmware upgrade makes the earbuds more convenient to use and improves quality of voice transmission performance during calls. The device now reproduces more natural and quality sound thanks to the upgrades within the ambient sound mode. 

The algorithms that used to capture surrounding sonic elements have been redesigned so the earbuds can capture a wider range of frequencies than before. The improvement not only enhanced the ambient sound experience, but also makes the earbuds capable of recreating a more natural mix of music and surrounding sounds. 

While noise reduction shows significant improvement, an added functionality now wakes up the headphones from "auto power off" mode. The new feature-loaded touchscreen allows users to smoothly perform general operations such as playback/stop, back a track, forward a track, volume reduce and volume increase.
