Sena SMH 10 Dual Pack
I just got back from a trip around the Northeast, NY/VT/NH/ME/NH/MA/CT/NJ... roughly 1660 miles this week and the Sena SMH-10 performed virtually flawlessly this trip.

ISSUES: The only real issue was that I lost connection with the GPS, and a simple turn off/on again resolved it. I would say this happened maybe 3-4x the entire week, not a real problem in my opinion and I’m not sure if it was the Sena of the GPS unit.

TALK TIME: Sena claims that the SMH-10 has a 10 day standby and 10hrs of talk. I can confirm that the claim to 10hr of talk is inaccurate. I would say the talk and/or listen to music time is more like 20hrs. No lie. A friend and I were talking and listening to music for about 6-8hrs one day, it was in standby-mode when we stopped for gas or eating. He never charged his headset that night, and then we used the headsets again the next day for another 6-8hrs before his unit finally died. That's pretty good if you ask me. I would say with high confidence that you could easily go all day long, with music/conversation going for at least 10-12hrs easily.

RANGE/DISTANCE: The range is the biggest issue, but they did what they claimed.

The range of 900 yards is pretty accurate... that works out to just over ½-mile. We tested the 2 units to 0.4 -0.5 miles. The line of site worked great, full-duplex and incredibly clear audio, when you get to the limit around ½-mile, it starts to crackle, but when you look in your mirror, ½-mile is pretty far and unless you really get split up, you're never really that far back riding when in group formation. It truly is line of site on curvy roads, it breaks up more.

On the highway, we were testing distance, and Craig was back about 0.3 - 0.4 miles and we were fine chatting but when a tractor-trailer pulled in-between us it got spotty for a bit until he moved back to his original lane. This is my ONLY complaint about the unit, the distance, but they do say line of sight and the 900m distance, they aren't lying.

HELMETS: I wore a Nolan N-90 modular and my friend wore a full face (non-modular) on a sport bike. The units are VERY easy to install, you just need to make sure you can slip a thin 2-credit card thickness plate between the outer shell, and the inner liner, which I believe in most helmets, that is not a problem. It mounts on the LEFT side, I do not believe it would work on the right based on the boom mic pointing out the front of the unit and you do need the mic near your lips.

I did find out that the new Nolan N-104 might be an issue as they moved the inner 'fighter pilot' shield lever to the lower front of the helmet (at the bottom edge) and it may interfere with the boom mike that comes out the front of the unit. Other than that, if you helmet is like most, it should be fine.

CLARITY: At 70mph, we were carrying on a very clean/clear conversation and the music sounded great in between talking.

PHONE CALLS: Why? Phone calls, if you want, work great also. Best thing is to pair the phone, to the GPS, then the GPS to the Sena. I found it works best if you turn on your phone, then GPS and let them sync, then turn on your headset to pair to GPS. I don't want to use my phone while riding, but did and I could hear others, and they said I sounded good on the 2x I tried it. Craig did use his a few times and he said it worked great. Again, I'm riding, I don't want to talk to anyone, if it's an emergency I'll pull over.

I did talk quite a bit with the helmet flipped up and I have a fairing on my HD Road King, and non-stock pipes. At cruising speed (55-70) I could hear and be heard clear with no wind noise, and when under throttle, Craig said I was still very clear with virtually no exhaust noise.

WATER PROOF: We didn't get caught in any rain, fortunately... but, unfortunately in the fact that I can't say anything about their ruggedness and waterproof abilities.

CHARGING: It takes about 2.5hrs to fully charge them each night.

PAIRING: To pair to Senas, on both units hold the Jog Dial down for 5 seconds, they start to flash, then tap only one unit to pair them and Viola, done. After that, whenever they are near another paired unit they automatically connect and I never had any issues. Pairing the GPS is slightly different as you have to hold the phone button, once blinking then tap the Jog Shuttle. Very easy, and well explained in the manual. You can pair up to 3 other Sena units (4 total connected)

MUSIC/BOOKS: I have MP3's and Audible books on my Zumo 660 and they sounded great with one caveat.... does anyone know of a program that will make ALL audio files have the same volume? Some are much louder than others, and some are so quiet, that even at full volume on the Sena it would barely be audible. Overall, very good sound.

GPS DIRECTIONS: The Garmin voice, cuts in WAY too many times when you're talking to others, and at the most inopportune times. When she does, you lose the comm to the other Sena unit(s) until she's done and then it takes about 5 seconds for comm’s to kick back in. It gets more noticeable (aka worse) as you get closer to your turn as she cuts in at roughly 1mile, then 0.5, then 0.1, then at the turn, and finally then after telling you to go xx miles. She's a PIA. I wish there was a way you could tell the GPS to only give audible comments at say, 1mile, then only .2 miles and then again after you make your turn... or whatever your preferences are. There is no warning tone on your end, or your friend’s headset other than if you’re talking you get cut off, and after a few times, you both figure out timing. Annoying but not a deal breaker.
-Crystal Clear sound
-Easy to Pair to GPS or other SENA units
-Full-Duplex, nothing to press to talk
-Easy to switch from Comms to Music, and back. (you can use VOX if you like, we didn't)
-Large, easy to find and use Jog Shuttle
-You can plug in MP3 music (or GPS) so you don’t lose comms, but you need wiring at that point.

-Distance/Range. I just wish the range was more like 1 mile, regardless of line of site, but it is Bluetooth, and it does exactly what they claim.
-The random (maybe 3-4x all week) BT disconnect to the GPS (not a deal breaker)
-Can only connect 4 units at once unlike FRS/CB (but those are not full-duplex). Others can do up to 8 units at 1 mile but are 2x the price and as Bluetooth evolves, so will the units.

Not a Con against GPS or SENA, but they really need to standard the Bluetooth format so you can talk to other brands, like CB or FRS. It's BS in my mind that only SENA can talk to other SENA units, etc. If they make it uniform and you can use Sena to talk to other manufacturers units and that would be awesome!

That's my report and I would not hesitate recommending these to anyone!

No more quiet rides with my wife
I had been thinking about purchasing this system for a year and finally pulled the trigger. RevZilla had it at my house within a week and I put it on my helmet (Shoei RF1100) in a matter of minutes. I didn't need to alter much on the helmet just cut a little plastic so the wires could go behind the padding. It took a little more effort and thought to put it on my wife's helmet (Vemar VSREV), but that was primarily because it didn't come with a recessed and designated place for the speakers.
We did the obligatory walk around the house with the helmets on and they worked perfectly.
We took them out on our first ride the other night and they again worked great. Push to talk dial is extremely easy to find and use while driving. Sound quality was good even at 75mph, but started to fade a bit if we went faster. We used the hard wire to attach a Zune player and it worked fine for both of us using a splitter. Push the dial and it pauses the music so we can talk. Push it again and the music resumes. Haven't tried to sync it with my cell phone nor am I going to, I need to keep some peace and quiet while riding.

Not exactly trouble free...
I bought this mostly for the ability to answer phone calls while riding. I did also use it on a 2000 mile trip this past summer. For starters, I had a hard time loading the latest firmware into the unit which SENA suggests you do before use. The software would not recognize either unit. After swapping cords multiple times I was able to get the firmware upgrade done. I have recently checked for new updates and again, I can't get the software to recognize either unit so I gave up. The helmet mount is so temperamental to screw tightness. If the screws are too loose the mic won't work, if screws are too tight, the mic won't work. I have also not been successful in getting the voice activated intercom to work. Every time I want to start an intercom conversation I need to press the jog dial. The instructions claim you can speak any word loudly to activate, that does not work. As for being able to answer and make phone calls. That feature works good when the mic is actually working. Last time I tried to use that feature the mic wasn't working so I couldn't call out using the voice activation. I had a call come in, once I answered it the caller couldn't hear me due to the mic not working. The unit has SO much potential to be great but they need to iron the bugs out of it. I feel like I'm part of their R&D dept.

So easy to install and use with BMW K1600GTL
After easy FIRMWARE update from Sena, It paired with BMW k1600GTL, NAV IV GPS, and Galaxy note 2 without any problems. It sounds great with onboard sound system and attached to my Shoei Neotec without any installation problems. I would recommend this product to all BMW riders using onboard bluetooth system.

A headset you won't want to ride without!
I have had my SMH-10 dual headsets for about 2-3 years now. They still function perfectly and still hold a heck of a great charge! I can connect to my cell phone and play music whenever I want and there are no cords to run to my backpack or my jacket. This was the best investment I have ever made to my helmet or my riding gear. It is very easy to chat with the person on intercom and the mic has little wind noise/feedback on full face helmets (Shoei & Bell). I wouldn't go with any other brand. It is also very easy to update the firmware from Sena on this unit. I find the unit easy to work with race gloves on and that is a plus. I don't want to take my mind off of driving or watching traffic at a light to play around with trying to change songs or respond on the intercom. You don't have to with the SMH-10D. If you are considering getting an intercom system, you can't go wrong with the Sena. I would recommend this unit to anyone. Plus, if you have a Bell helmet, the pockets in the helmet are a perfect fit for the Sena speakers. It doesn't get any easier than that to install!

Amazing technology
It was a little tricky to mount the main unit on my Shoei RF 1200 because of the side cut out, but just keep at it and it clamps on quite well.
Use the little pads behind the speakers to bring the closer to your ears.
The RF has too much low frequency wind noise to hear the speakers at over about 50mph so ear plugs actually make it easier to hear. The foam ones block too much sound (too high a dB rating) so I'm using those silicone flanged units and at full volume, I can hear quite well. Still looking for ear plugs with a lower dB rating to improve this.
The clarity of the phone is what truly amazes. I have yet to have anyone mention any background noise- even at 80mph. My buddy hasn't installed his yet so I haven't worked the intercom but if it is similar to the rest, it will be great.
Other commenters complain of not enough bass to hear their Metallica at head banging volumes, but it occurs to me that that probably isn't a good idea anyway.
Unit appears to be very sturdy, but I've only had it about a month and haven't really put it to the test. Haven't dropped it or ridden in the rain yet. That's why I didn't rate it for durability.
I'm not sure how much better the 20S model could be, but the SMH-10 is now a real bargain.

Excellent Communication Device! Just love it...
I am a passenger on my husband’s HD Road King, just got my motorcycle license last week and will be ridding my own motorcycle soon! We got this product for various reasons,1. To communicate with each other while riding, 2. To listen to music while on the road and 3. To be able to answer our phone while on the road if our kids have an emergency. We are extremely happy with the customer service at Revzilla. With this said, I will add that we are also very happy with the product itself. The Sena SMH-10 Bluetooth Headset Dual Pack is a great value. The intercom feature is great, there is some noise while in use but expected from this kind of device. The Bluetooth feature works great and music sound is excellent via Bluetooth and via cable as well. The pairing and connection were very easy out of the box. One of my questions was if the two units were able to connect to 1 iPod touch at the same time, and the answer is yes. I was able to connect both units to my iPod and my husband and I can both listen to the same music from my Ipod at the same time. Please note that I did not buy any other device in order to communicate to the same music player at the same time.

Excellent product
I bought these for my Bell Mag-9 Rally Helmets and they installed in a flash. It took me longer to watch the install videos on YouTube than it did to actually install them. They are perfectly solid when mounted Sound is good but you need to find the sweet spot for the speakers. Wind noise can be a problem on the mic with the shield up but acceptable.
Over top notch product. Especially now they're half price giveaway prices !

This is a must have communicator system
If you want to enjoy your music player and listen to your GPS navigation and talk on the phone while riding… then get this unit. I bought the combo pack so that my wife and I can communicate while riding. the speakers are loud and clear. At least you can concentrate on your ride while you GPS speaks to you with turn by turn directions.

I did my research on all bluetooth devices out there and I decided this was that best unit for me.

I notice some people prefer to look at their GPS screens with no audio while riding please do not do that as it's not safe, all it takes is that moment of distraction because you are trying to figure out which exit or turn to take and when on a motorcycle you can easily cross over to the wrong lane and get hit by another vehicle (this almost happened to me once but thank Jesus there wasn't a car on the next lane) do the right thing and save your family the pain.

I will be buying the new version made for Half helmets due to be out in a month so that I can use it when the weather is hot.

Makes me wish I bought one sooner!
I had been looking at different Bluetooth options for my motorcycle for a while now. After my research it seemed that the sena SMH10 headset was the best way to go. The headset was easily installed and was easy to operate with gloves. We went for a new year ride with Highs around 35 degrees and so we had thick winter gloves, masks over mouth and neck to stay warm and the system worked flawless(picking up voice). Sound quality was amazing even at interstate speeds and the headset volume was plenty! I never had to go to the max volume. It is nice it links to sena and non-sena products and it significantly ads to the Riding experience! Would highly recommend this headset!

Wanted an intercom for myself and my riding partner. The bluetooth connectivity is excellent and the device is simple to set up, install and use. It does not pair with an automotive style gps but the manual is clear about that. I use my phone for gps and it works seamlessly. You can connect up to four riders with this unit but it isn't a conference call. You can also connect with non Sena sets. A lot of wind noise through the mic. Good value for the money

Steve A on Mar 12, 2014
BEST ANSWER: the difference is that one pack has the microphone attached to it and the other not it depends for what kind of helmet you want it
Can this be used for both open face helmet and half helmet? Is switching between helmets easy?
A shopper on Dec 3, 2013
BEST ANSWER: For a open face full helmet I'd generally say yes. Installation would probably be the same as a full face helmet which I installed it on. Installation entails securing the main unit via two hex screws to the bottom shell of the helmet, then running the speaker wires under the padding. It's helpful if the padding is removable. With a half helmet the securing would be the same, and running the wires would likely be similar, however the installing of the speakers would mean securing them to the webbing of the half helmet. A type of supplied hook and loop tape is used on the speakers. I believe it's going to be dependent as to whether the neck skirt is permanently left on or the ear webbing design allows adhesion of the speakers. Wind noise would definitely be a factor. On a full helmet this product is great.
Me and my wife have different music tastes. Can we listed to different music by pairing to our own iphone's? but still be able to speak with each other while riding?
A shopper on Jun 9, 2012
in fact the way it works, each person needs there own music source.

Most people just pair it with there phone, then play music on your phone.
Or you can selective pair with your phone (for telephone use) and a separate Bluetooth MP3 player.

99% of all external devices (phone or mp3 players) will only pair with 1 headset.

Would like to know if the Sena SMH10 Boom Microphone attached to unit will fit a Shark Evoline 3 helmet?

Or, do I need the Universal Microphone kit

A shopper on Jan 7, 2014
BEST ANSWER: I have my Sena SMH installed in two helmets AGV, but I did installed a Cardo system in one Shark Evoline and I'm sure the Sena SMH will fit perfectly. You do not need the Universal Microphone unit.
Do they work with victory sena dongle?
A shopper on Feb 14, 2016
does the Sena SMH 10 come with a charger or do i need to purchase it seperatly??
A shopper on Aug 19, 2013
BEST ANSWER: it comes with a usb cable for charging and for firmware updates. but that won't let you charge from a 110 outlet (wall outlet) you will have to plug it into your computer or get a device that you can plug into the 110 outlet that will provide power to a usb cable. I use the little one for my phone (I have an iPhone) or just plug it into my computer. Their are two of these cables, one for each headset.
Is this unit waterproof at all, or does it have to come off when it rains?
A shopper on Dec 18, 2011
BEST ANSWER: We bought the 2-unit set. One performed flawlessly in a rainstorm while the other one had a lot of static and squealed so bad that my partner had to turn his unit completely off. We switched main units but he still heard static and loud squealing. I didn't. We guessed that it must have been the microphone helmet clamp unit on his helmet that was causing the problem. We both wear 3/4 helmets and both of us had our visors down at the time. Once his helmet and Sena equipment dried out later in the day it returned to working just fine. We haven't tried the units in the rain since that time.
Can 3 separate riders connect to each other concurrently. I understand rider and pillion should not have any issues but I am looking at communicating with at least 3 riders at the same time (incl. myself, ie. a to b,c, b to a,c and c to a,b)
A shopper on Sep 12, 2011
BEST ANSWER: With the most recent firmware update (3.3), you can now conference-intercom three riders together. It seems a little awkward, and I haven't tried it yet so I can't comment on how well it works. The manual has been updated to describe the process. It sounds like A initiates an intercom call to B, then C has to intercom to A or B and he is conferenced in. I would prefer a default conference option, where all three riders would be included automatically when an intercom is open. But I can see where this wouldn't work in a four-rider set-up, so maybe it's best this way. Also, it disconnects all three riders' cell-phone connections during the conference, reconnecting automatically after the intercom closes.

Note that it may be awhile before the units shipped from RevZilla have 3.3 installed, so you will probably have to update the firmware through the Sena website.
Do you HAVE TO be connected to Bluetooth to use the intercom to speak to your passenger?
Carter T on Nov 6, 2013
BEST ANSWER: The intercom is "Bluetooth" technology. All you have to do is have the units turned on and paired to each other per the instructions and you are talking clearly to your passenger or to your other rider on another bike. I have done both and it is crystal clear. Make sure the microphones are in the right position and out of the wind. It paired easily with iPhone for music or calls. The install and instructions were straight forward.
