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. 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. You can then turn on the connections by pressing the intercom button on one of the bridges to start the bridge to bridge connection, then each end unit until all 4 intercoms are talking. Thanks to Bluetooth V3.0, the LX-B4FM offers great audio quality for both incoming and outgoing sound. The intuitive button operations make the LX-B4FM a perfect companion for motorcycle helmets.

This model is versatile and able to work with other models of Bluetooth compatible headsets, all smartphones, MP3 players, and other Bluetooth devices. You may have trouble with the voice conference feature at times since it can lag and cause a type of echoing effect that will make it difficult to communicate with your fellow riders.I must caveat this with a few things. One, I don't like that when I'm in intercom mode, Bluetooth to my phone is disconnected so I can't hear Google maps directions. Not a big deal for me as I have a phone mount and can see the directions easily, plus Google maps talks to much lol. Second, the pairing is a little confusing, but once you understand the pairing scheme, it sorta makes sense. Next, we are not using any of the other features simply because we are not interested in them. But I can see if you wanted to also stream music or anything Bluetooth, not being able to use Bluetooth and intercom simultaneously would be a deal breaker. You can do this if your only connected to one other unit, it's the bridge functionality that stops the Bluetooth, so just have 2 people doesn't require a bridge and then you get full functionality. I'm not sure how this compares to the higher end Sena and Cardo systems, I'd have to imagine that for 2x the price they have better features. But I cannot imagine having a better connection, audio quality and wind/noise cancellation. It's dead quiet when nobody's talking, how does it get better than that? Lexin is a popular name brand that most motorcycle riders are familiar with. Over the years, their headsets have continued to improve in terms of features, functionality, and overall reliability. Next, you pair one end unit to a bridge unit on one motorcycle, and repeat for the second motorcycle. These pairings are done on channel 1 and use the vol + and intercom buttons. They pair the same way as the bridges. 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 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. It’s also compatible with S Voice for Samsung voice commands, which also allows you to receive or make calls hands-free, access FM radio, listen to music, or listen to GPS directions. Universal Pairing and Voice Conference

If you’re riding with other people, then the voice conference feature can be a total lifesaver. If you’re tired of losing one or more members of your riding team due to miscommunication on the road, then the conference feature will definitely come in handy. One feature I would like added is the ability to have a second blue tooth channel so my Android phone could stay connected for music, phone, GPS, etc. Still, for the price this setup is hard to beat. This leading model by Lexin comes loaded with all the right features for the casual and serious rider. The Lexin B4FM motorcycle Bluetooth intercom is reliable and can be the best piece of gear you bring along on your next cross country ride. But is it really a solid performer like so many riders claim it is? Is it worth the higher price tag? And can it handle regular use? Let’s find out. At dinner, we were talking and all concluded that this intercom does what we needed it to do, was surprisingly quiet all day, and has plenty of range. We never once lost connection other than the range test we performed.
