LEXIN B4FM Motorcycle Bluetooth Headset, 10 Riders Helmet Bluetooth Intercom, Universal IP67 Communication Systems with Music Sharing, Noise Cancellation, FM Radio, Fit for Snowmobile, 2 Pack

I was doing a ton of research on which helmet Bluetooth/intercom to get and of course the Sena ones kept coming up as the best and so no and so forth. I was ready to pull the trigger on SMH10-11 due to the it being reviewed for better sound quality/volume in the helmet, but just as I was about to I stumbled onto these in a review. I look them up and lots of reviews about this product are ex sena users whose devices broke and they opted for this cheaper option. I was sold and happily made the purchase to get two units for the price of one Sena.So about these:Setup:Took a sec in my first helmet, there aren't very clear directions about where to put the speakers or how to run them in the helmet so for my first helmet I didn't use any of the velcro/adhesive until I knew how it sounded and was sure I was right. I put the left one right behind the left ear pad, tried to run the wire behind the padding as much as I could up to over the head and put the right behind the right ear pad. The unit comes with both the boom and wired mic so you can choose whichever fits your helmet style. You can use either for a regular full face, but have to use the boom for open face/ modular ones. I choose the cable one since it was a regular full face, fan it up to right in front of my mouth and used some electrical tape to just hold the wire on the helmet so the mic flops around a bit but stays mostly in front of my mouth. After that pairing with my phone and use was easy.After installing it on the first helmet, the second was much easier. However, I will note that since the second helmet was brand new, and the first was about 12 years old, the second helmet had little cutouts behind the ear pads to specifically put speakers. It also allowed all the padding to move around so it was much easier to hide the wires completely behind the padding. This helmet was a modular helmet so it needed the boom mic. It was pretty straight forward. One other thing, not sure if this is due to manufacturer or age, but the first helmet the side where I needed to mount the unit wasn't flat so it makes it wobble a bit, the second unit it's perfectly flat so the unit sits snuggly on the side of the helmetSound Quality:Once paired up I cranked the volume up standing in the living room to see how it sounded with my speaker placement. They got pretty loud but crackled at high volumes. There's not a lot of low end on these so any bass heavy songs will sound like a phone speaker kinda. I made a call and the person on the other end was ringing through loud and clear and they could hear me as well. Next I hopped on the bike and took it up to highway speeds. I noticed I could barely hear the music and definitely couldn't hear phone calls. However, people on the phone said they couldn't hear the bike or wind and I was crystal clear. I figured the situation might have been due to my speaker placement. I got back home, shifted the speakers around a bit and tried again. This time, much better audio quality all around.On the second helmet I haven't tried the road test as yet since it came in a bit later and it's winter now so it's harder to find comfortable days to go out.Intercom:Intercom setup was a little confusing at first, but I attribute that to me misunderstanding the directions. I believe the two units come paired already out the box and in trying to set them up I unpaired them. I then re-paired them following the directions in the book and tested them out. Initially the second unit the sound wasn't coming through to the first, but it was because we were testing in the house and the second person wasn't speaking loud enough to get over the noise cancellation of the mic. Once they started speaking louder as you would on the bike, everything came through loud and clear. I haven't been able to try the pairing on the bike because as stated above it's still winter and is hard to find good days to ride.Conclusion:So far I'm definitely happy with this purchase. The price for two units was cheaper than a single Sena. The sound quality seems to be pretty awesome so far. The setup was pretty easy, the Bluetooth is easy to operate the voice commands. The buttons are raised and are distinct enough to be easily identified and pressed. I'm excited to test this on longer rides with both units on.P.S. I also have a newer helmet coming in and I'll transfer the unit from my first helmet to this one and see if It improves the audio quality more.

Our stock Honda GL1800 headsets were loud, but had no noise-reduction for air blowing past the helmets and other wind turbulence that helmet mics will always pick up, which creates noise that the bike's audio system will mix with our voices through the intercom. Couple that with most non-current-year's GL1800 models' inability to allow two-way cell-phone conversations without expensive modifications and you'll have a system that works fairly well at low speeds (under 40 mph) but becomes unpleasant to intolerable as the speed increases. Even wearing custom-molded ear plugs the voice to wind-noise ratio is such that the voices coming through the earpieces are hard to understand, and can often become quite hard to understand above 50 mph as speeds and wind buffeting increase when approaching Interstate speed limits (65-70 mph).Enter the Lexin B4FM--as the wind rushes by you'll hear it, but NOT through the B4FM's speakers (one in each ear). And--different from the bike's intercom, you won't hear your own voice when you speak. You'll only hear your fellow passenger on the bike.Does wind buffeting sometimes make your co-rider hard to hear? Yes sometimes, but it's only because helmets themselves are often not well sealed around the bottom and back, where air can cause noise within the helmet due to vacuum from air rushing by. As nearly as I can tell little to none of this air-buffeting is audible through the helmet system. Though the mic may pick it up, the noise-filtration of the B4FM works effectively to eliminate most everything but the voice of your co-rider.A note about wearing ear plugs: We do so because to go without them is to be gradually deafened by the buffeting wind and other noise of riding at speed. They are highly recommended by experts, including ear specialists to protect your hearing from long exposure to high noise levels. That's the only reason we wear them. This requires that the helmet speakers be loud enough to reproduce voices intelligibly despite the ear plugs--and the Lexins do this pretty well. Do I wish they were just a little bit louder? Hmm. I'd have to say yes, I do--although I don't have to ask for a sentence or phrase to be repeated often, occasionally a repeat is needed at 65-70mph.NOTE: the picture I'm showing is the helmets before testing--I had just installed them, which brings me to what I consider is a winning issue--these were the quickest install of any I have ever performed over years of fitting aftermarket intercoms and headsets to helmets. I installed the first in 15 minutes, and the second in just under 10 minutes. If I hadn't been so careful in the effort, it could have taken less time.ACID TEST, BOTTOM LINE--we just finished an over 1400 mile round trip to the eastern mountains (from Illinois (the land of endless corn and soybeans) riding the interstate on flat land, and the curviest mountains we could find when we got into the mountains. We considered these a big success, much better overall than the stock GL1800 intercom system, with little to no noise transmitted through the earphone speakers, just our voices.Disclaimer: I didn't care about listening to music, just my partner, so I didn't bother trying the radio function. Also though we paired our phones to the devices, we received no calls while we were riding, so that function didn't get tested either.The mics can get turned away from the rider's mouth, so an improvement would be to implement a way to keep these properly oriented.The clamps that hold the devices to the helmets can pull loose, so a nylon or plastic set-screw that could hold them onto the helmets might be a way to prevent them from coming off while handling the helmets. We never noticed them loosening while riding, only now and then when handling or carrying the helmet. These things can be a pain to attach to the helmet, and while the included spring clips can be attached to hold the plastic clamps open for attaching, you'll want to remove them immediately afterward. They are unsightly and will get in the way if left attached to the clamps.

These work perfect for us! However they can be a bit of a hassle to pair together. With some patience they always pair but they take a minute or 2 sometimes. For me the range is great! I had no expectation of being able to talk to anyone 1/8 of a mile away in the woods in the mountains. Save hundreds and just get these they work just as good as the big brands! If they paired together better these would get a 5 star.
