The 5S Bluetooth Headset creates a new standard for entry level helmet communications. Featuring Bluetooth v5.0 and a built-in LCD display, increased audio performance is matched by an even easier to use rider interface. High definition sound quality, music sharing and built-in graphic equalizer profiles tailor audio performance to every preference and playlist. The Sena 5S also lets you answer phone calls hands-free, accept GPS turn-by-turn directions and communicate in duplex with your passenger or other riders. Speakers are now designed with a beveled taper for improved fit in helmet speaker pockets. These 40mm diameter drivers separate themselves from previous generations with a marked increase in maximum volume, bass and clarity.
