Panasonic releases firmware update for its latest RZ wireless headphones series

Dubai, United Arab Emirates

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. All programs are available from today.

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.

“Panasonic is constantly looking to provide top of the range products to enhance customer satisfaction. These wireless headphones, now enhanced by these latest updates offer outstanding performance. No more interruptions on calls, not to mention crystal clear audio, we know that these new wireless headphones will be a must have gear,” commented Masashi Sakatani, Manager - System Solutions and Communications Division, Panasonic Marketing Middle East & Africa FZE.

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.

There are two versions of the firmware introduced:
RZ-S500W JMS1ZY 02.50
RZ-S300W JMS1ZX 02.00

Main features of the upgrade:

1. Added touch sensor customization option

3. Added explanation of how to wake up the headphones from the “auto power off” mode
