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 helmet Sound 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.

If you are looking at helmet communication / Bluetooth devices, these are an excellent choice! I was very skeptical at purchasing a "cheap Chinese" Bluetooth comm unit and was leaning towards the Cardo FreeCom 2+. But, after reading every review I could find on Lexin products, I went with it. I am VERY pleased with this purchase because it works well! -Easy to install on my Fly Conquest helmet. -Easy to pair! Paired to my iPhone 6s with no issues, very quickly. And, quickly and easily paired with the 2nd Lexin unit I bought (duo). -Paired and works well with a different brand integrated Bluetooth helmet that I own. -Volume is incredible! I have hearing loss from my job and I have NO issues with the volume output of these. In fact, I had to turn down the volume because it was way too loud at first. I typically run it at 1/2 - 3/4 volume. -Intercom (rider to pillion) was excellent and had no issues hearing when speaking in a normal conversation tone while traveling at 65 MPH with face-shields partially open. When the face shield is closed it is crystal clear. -Phone calls are crystal clear with little to no wind noise (used with a Fly Conquest full-faced helmet). I received a call from my wife (driving her car) and me on my bike traveling 65 mph and had no issues communicating or hearing each-other in normal voices. -Audio quality is decent. I did not expect Bose, Klipsch, Sennheiser or Beats quality sound from this unit. However, the sound quality is not bad when fitted well in your helmet. It takes a little work for positioning the speakers to get them in the right location (directly over the ears). But, It makes a huge difference in sound quality. I noticed that sound quality drops exponentially when the speaker is not directly over / covering the ears. So, be sure to position them correctly and I am sure you will be happy with the sound quality, for what these are. I ride a sport-tourer with stock exhaust. I have read in some reviews that they "are not loud enough to hear over the exhaust..." that is ridiculous. If this is the case the exhaust is too loud. Period. If I had to make an educated guess, this came from a V-Twin cruiser with custom exhaust and or straight pipes. I am very happy with these units and I am please with the purchase. I would recommend them without hesitation.

Just completed a 3k trip with 4 other bikes. Here is a breakdown of the good/bad with these headsets. - Installation Install was pretty straight forward. I had to remove the fabric covers over the speakers to get them into the speaker cutouts for my helmet. I had a modular helmet with a sun visor so the unit itself is mounted in a weird spot, but it works. - Bluetooth music player works pretty good. Not much bass, but you're on a bike so pick your battles. Even with 30db earplugs in at highway speeds this thing works really well. Even better on curvy backroads. - Phone calls at highway speeds 70mph Called the wife on the road. I could hear her with no issues. Beth said there was a bit of road noise but not enough to bother her. We talked daily for about 20 minutes a time, works better then my truck according to her. - Intercom with 1 other person. Works as advertised, as long as I can see the other bike no issues at all. If you get into a forest with curvy roads expect to disconnect, but unit will reconnect once it finds the other bike, - Intercom with 2+ people This is where the unit fails for me. Day 1 we were able to get connected in the driveway. Driving on the interstate the sound quality started to fail. First fuel stop and we were split into 2 different groups. The headsets wouldn't reconnect to all 4. Day 2 we could get 3 units to connect, 4th unit would go in and out of coverage. Day 3 we could only pair for an individual and not the group. Day 4 we got back together with all 4 units but only for half the day. Also found out for better sound quality, you need to pair the units in your riding order. Rider 1 and Rider 2 needed to pair first. Then rider 2 with rider 3. If Rider 1 and rider 4 pair first, sound quality worsens. Finally decided to just go a conference call. Sound quality on the conference call was 50% improved over the intercom function. - Battery Life 9 hours of saddle time, leaving this unit on for over 13 hours a time. This headset seems to good to be true. - Rain? 2 days of solid rain, our riding. No issues at all - Mics Unit comes with 2 mics. I like the mic that is moveable, it allowed us to get it in the right spot for each conversation. Permanent mic is nice, but if its not in the perfect location you will need to yell.

Update: since my review I’ve been very pleased with the customer service I’ve received. ————- Based in sound, speed and helmet type because we both have 2 completely different experiences with it. My helmet is Z1R Mid- the padding doesn’t push right against my ears which we think is why it makes a difference. It sounds great if you’re not driving, super loud and I can hear my husband clear. Pass 55mph the music sounds like as if you’re listening to the live version of whatever song you’re playing Pass 65mph you can hear the music, can’t really make out the words unless you know the lyrics. Ad once you hit 70-75mph the sound of the wind itself over powers the sound of everything, you know there’s music playing but the sound of the wind takes over. As far as the speaker goes, Once you pass 65 mph it’s really really hard to hear someone talk. The wind is too loud to make out the words. The pair sharing mic does work but you have to wait about 10-15 secs after pressing it to start talking. Sometimes after you ended the mic sharing option the music you had playing does not play again automatically which it should. And pressing play doesn’t make it play either. I’ve had to pull my phone out and hit play from there. Which defeats the purpose of Bluetooth in my opinion. Over all, my AirPods have better quality as far as sound goes. I think it’s because it cancels out some of the wind noice since it’s directly in your ear. The only plus side about these is that you can communicate with the other person, easier. Since sometimes Siri can’t hear me after 50mph The set up was super easy, you can adjust the placement of the speakers inside as many times as needed (my helmet does not have ear cutouts so the placement of the ears isn’t as specific as it is on my husband helmet making it harder to place them in the right spot but after a few tries we got it in the right place, this makes a significant difference in sound) , pairing both together was easy as well as pairing it to the phone. Came with 2 different sets of speakers. I assume one is for 1/2 helmets and the other for full face. Now that was for my helmet - (Z1R) For my husbands helmet - BELL mid his sounds much better and he can hear me clear as day. Even at 80mph and up no issues with his other than the music not playing automatically after the mic sharing. His helmet does press on his ears and is more noice cancelling than mines is. Which we think it’s why his had no issues with sound. His helmet had ear cutouts so it shows exactly where the ears go in the helmet making it easier to place the speakers in the right spot his helmet. The mic does sound a bit loud, but then again you’re on a bike right! We placed the actual Bluetooth device on the right for one helmet and on the left side for the other one. So it is modifiable from side to side depending on which is more comfortable. The buttons are relative hard to press with gloves on, but it gets easier to find the right button after a while. Make sure to not dubble press the volume up button and hold it instead Bcus it will call whomever you last called. Over all for me the experience is a 3.5/5 For my husband it’s a 5/5 Considering price and all, Giving it a 4/5 I would buy these again, and I do suggest them. Noting that your helmet type does play a big factor.

We only use this for the intercom while snowmobiling. I can't talk to the Radio feature or if you can answer a phone call. I absolutely love the intercom, it was simple to set up, it's a little different install helmet to helmet but not a big deal. Directions are decent. When you pair a third helmet you have to pair the first two then turn one off and then turn the 2nd and 3rd helmet on to pair, once paired everyone pushes their intercom button and you're connected. The directions are a little vague on shutting off one of the paired helmets to add another. The range is good, it can be spotty through dense woods, you're good for at least a 1/4 mile. If you go out of range you don't have to do anything as soon as you're close enough you can hear the other rider again. Most times there's just a little static as you get too far apart. One side note, it's on all the time, anything you say like a 4 letter word about a bump or something, or my daughter sings sometimes when she's nervous everyone hears. My sons sled is a little louder, if no one is talking you can hear his sled when he's really in the throttle, nothing crazy just leaving an honest review. You can turn the volume down if it bothers you. Overall, I'm very happy and would buy again. Great price compared to others on the market and it's stand alone, a lot of other cheaper ones on the market use your phone's blue tooth, these don't need anything to work. The battery life is good also, they tell you the charge percentage when you turn them on. Couldn't be happier.

Purchased these a few months ago as I wanted an intercom system for when I ride with my wife. When I first received them and set them up, I had some much trouble getting them paired correctly, I almost returned them. Some patience and time watching their YouTube video, and I was able to get them to work. So, some good and bad: The good: 1. Relatively inexpensive 2. Intercom between two devices (I haven’t tried more), works well once set up. 3. Bluetooth to a phone for music also works well once set up. 4. Sound quality is decent, not great, but ok. The bad: 1. Set up can be confusing (also make sure the stereo jack is plugged all the way in, it should be an obvious thing, but it isn’t). 2. Once paired to a phone and used for music, the intercom function tends to stop working until the units are paired to each other again. It’s supposed to turn on the intercom function when the intercom button is pressed, that doesn’t seem to work when also paired to a phone. 3. You can’t share music or content from one phone across both devices. Each has to be paired to a separate phone. 4. Sound is just ok, discernible but not quality. 5. Buttons are big and “glove” friendly, but it’s still had to tell which one your pressing.

Seems pretty decent so far. Bought these to replace my old Scala rider headsets, as they’re much cheaper in price, and we mostly wanted to listen to music and navigation while riding. Battery life has been great. Says it takes 2.5 hrs to fully charge, but I usually plug it in on Sunday night, and use it all week back and forth to work on a single charge. I’ve never gotten below 50%, even after some long weekend rides. Sound of the speakers is plenty fine. Not a lot of bass, but they’re small speakers so that’s expected. My only complaint here is that my scala units raised and lowered the volume automatically with speed, these don’t do that. Again, more money generally gives you more features, so I can live with it. Using the clamp-on style clip, as the shape of the stick-on style made them too flimsy for me to trust. Depends on the curve of your helmet, but for me it didn’t match, so the double sided tape only had a very thin area to stick at the top and bottom edges, leaving the middle unstuck. No big deal, but I don’t remove it from my helmet to charge or anything. My scala I used to take off when I’d park my bike and leave my helmet chained to it for long periods so it wouldn’t get stolen. This unit’s plastic clip seems kind of flimsy, so I try not to pull it on and off very often. Bluetooth sync’s no problem to three different devices I’ve connected to. Have only tested the intercom across the house, but did notice it was staticky after pairing the units. May just be a line of sight thing, so I can’t really knock it until I test further on the road. Overall it gets the job done, and for the pair, it was still cheaper than purchasing one of the more namebrand units. Over 6 month review- Still very happy with these headsets. The girlfriend and I are able to listen to whatever we want independently, but with the quick button tap and wait for the beep, and we can chat. Automatically ends the chat after a short period of silence, and back to music/nav you go. Sound is decent and plenty loud. Battery life has been outstanding! I ride about a half hour each way to work everyday and only charge it about once every two weeks. Good choice and very affordable compared to the top brands in this market.

I got these to wear while I passenger on my husband's motorcycle. Finally being able communicate is amazing. The intercoms worked great and we never heard one bit of wind noise. Our favorite feature is the ability to connect more, so we will purchase additional ones as gifts for others we ride with. However, there are a couple things buyers should be aware of that we learned within our first 5 rides with them, over a 10 day vacation: 1. Do NOT hit buttons on accident. My husband commonly hit random buttons as he put his helmet on and off at stops. The unit gets confused. It stays on but stops working. The only way to reset them is to turn off and wait a few minutes before turning back on. After he started being more careful, we stopped having the issue. 2. It's weird that the power button does not turn them on and off, you must hold down 2 buttons for on and off. This is really just a reiteration of #1.... because randomly hitting jusy the power button just messes things up. but read the manual and know what buttons to push and when. 3. We tried to connect bluetooth for music twice and gave up. I'm not convinced yet that there's an issue, we were anxious to get on the road with the intercoms. During our attempts for connnect his iPhone we got the Bluetooth to connect to and he could play music. but once we connected for intercom the music stopped playing in his helmet and we never got it to play in mine. When we rode off without music but keeping phone connected he started hearing a beep every 30 seconds or so. This was super annoying and he had to turn his phones bluetooth off. Once again, I'm not positive this isn't user error... but we did follow the instructions in the manual twice without succes. 4. There are two mics with each unit and a clear winner, the mic that sticks directly to the helmet. The one that looks like a classic Britney Spears accessory does not stay bent perfectly still. When it moves and props up against the helmet the vibrations of the bike make a constant annoying radio static noise for the other listener. 5. The wind noise cancellation is AMAZING! Open visors, going down the highway at 70+mph or winding through curves and there was NEVER a distortion from wind. 6. We fully charged them before and after our first ride. Then we tested them to see how long they would last. Over the next week we rode at least 5 times, each for about 2 or 3 hours, keeping them on at stops. The battery said 100% each time we put them on. After at least 10 hours of intercom only there still seems to be plenty of battery life in them. We haven't tested connecting to a 3rd rider yet but are excited to test that functionality next spring.
