Enjoy Your Conversations with Higher-Quality Sound
Panasonic's new USB Speaker/Handset does the work of three ordinary devices. It's an internet speakerphone, a handset, and a high-quality PC speaker. Its easy portability lets you carry it together with your PC for use in the office or anywhere you go.

IP Soft Phone Speaker
Enjoy hands-free internet calls when you are too busy to leave your PC or when you want to converse while using the PC.

IP Soft Phone Handset
This handset can be used just like an ordinary telephone, for people who prefer to pick up the phone and hold it to their ear to converse. This also enables private, secure internet calling because the sound does not leak to other people in the area.

PC Speaker for Easy Listening
Enjoy high quality 8-kHz sound with your laptop computer for an easier and more comfortable listening experience.
