Sena Headset SF4 HD - Bluetooth communication system for driver and pillion communication or small groups up to four drivers New: with standard and HD speakers!
You now get two speaker sets! Each headset comes with a standard and HD speaker set so you can choose which speaker is right for you. The HD speakers have a louder and clearer audio quality than the regular speakers, which are slightly smaller and may be more comfortable for some drivers.
The communication system for everyone
The SF Series is designed to give riders just the features they need for their comfortable ride. The SF1 allows a Bluetooth connection to a smartphone, MP3 player or a navigation device, while both the SF2 and the SF4 also have an intercom function. All SF models feature the latest features like audio multitasking ™, quick charge and mute the microphone. The SF series is particularly impressive with its narrow and functional design that fits almost any helmet.
