Detailed Product Description:
Bluetooth Headset SF4 Single Special Edition
Connectivity & Communication for small groups. The SF4 is the ideal device when traveling with friends, as it offers connectivity for small groups. The SF4's four-way intercom has a range of over 1.2 km (0.8 miles), allowing you to stay in touch with your group in open terrain. The SF4 can also be paired with a smartphone to stream music, make and receive calls, and hear navigation instructions. Best of all: with the Audio Overlay_ feature, you can listen to music and use the intercom at the same time. Additionally, the SF4 features quick charging, so you're ready to go in no time.
HD speakers are now available for the SF4. Each SF4 comes with both a standard and an HD speaker set, so you can choose which speaker is right for you.

Mein erstes Helmheadset
Mit Sozia zu reden ist ok. Man muss sich nicht mehr so anschrein, wenn Mann 1,2,3 sagt hört der Partner erst ab 2 etwas. Bei anderen Biker hört sich es OK an bis max 400 Meter dann wird unterbrochen. Man kann Musik, Navi und Gespräch gleichzeitig hören erfüllt sein Zweck ist allerdings kein Highlight

Mittelmäßig
Habe mich für das Sena Sf4 entschieden, da es mein erstes ist und wollte nicht gleich 400€ und mehr ausgeben . Die Klangqualität ist nicht so gut . Hin und wieder bricht die BT Verbindung ab. Einbau war einfach und die Kabel ordentlich verlegen . In 30 Minuten ist alles verbaut gewesen . Sobald der Boxer läuft und die Windgeräusche dazu kommen , kann ich kaum noch was verstehen . Denke ich muss die Lautsprecher noch weiter unterfüttern , so das sie näher zum Ohr ausgerichtet sind .
