Lexin has a connection scheme where the intercoms are either an end unit, or a bridge. A bridge is a unit that connects to an end unit, and also to another bridge so 2 connections. The end units make only one connection to a bridge. So each motorcycle has one end unit, and one bridge unit, and the bridge units connect the 2 motorcycles. You start by pairing the 2 bridge units on channel 2. This is done by holding the vol - and intercom button until the unit goes into pairing mode, and you repeat this on the other bridge unit. Pairing mode is shown by an alternating red and blue LED, as well as a message through the speakers. Then, one either of the 2 bridges, you press the intercom button and the unit will say, "scanning" and then "connected". The LEDs on both units go blue. Durable, compact, and designed to work with most helmet brands, this headset will not take up too much space in a helmet, however, the large earpads can make it uncomfortable to wear for a long period of time if you’re dealing with a full-face helmet that doesn’t have any recessed space inside that’s meant to accommodate a headset. This model allows you to communicate hands-free, for a safer riding experience. With this type of headset, you can access Siri to control the headset, search the internet, answer or forward a call, end a call, and more.

We never once lost connection other than the range test we performed. Lexin is a popular name brand that most motorcycle riders are familiar with.

This model comes with a couple of mics, allowing you to choose between a boom mic for a flip face helmet or open face helmet, or a button mic for a full-face helmet. Waterproof Design This model can withstand a heavy downpour, unlike competing models that are only water-resistant. this means you won’t have to worry about damaging the headset if you get caught in a downpour. Headsets that are only water-resistant can handle light rainfall but must be removed in the event of a downpour. This model is designed specifically for motorcycle use.

Almost all Bluetooth MP3 players, smartphones, and audio dongles support A2DP to send stereo audio to Bluetooth headsets like the LEXIN LX-B4FM.The universal pairing feature makes the headset compatible with most types of Bluetooth earpieces and headsets on the market. The THOKWOK Motorcycle Bluetooth Headset is one of Lexin’s top competitors, and while it offers many of the same features, it has a voice conference range of just half a mile, which can be a dealbreaker for some riders. Lexin has definitely outdone itself by offering a one-mile range, which will allow you to stay connected to your friends at all times. Noise Canceling
