SMH10 - Can be used in a wet weather. Sena August 15, 2018 21:43 Follow SMH10 is very water resistant. Water resistance is one of the highest priorities in designing of SMH10. All buttons and ports are nicely sealed to provide excellent water resistance. Make sure that the rubber USB port cover is closed. Have more questions? Submit a request 25 Comments Date Votes 0 Lu Vencl November 30, 2011 03:32 I have found the SMH10 to be very well water resistance. I even went through a hail storm and the unit took a beating with no issues. 0 Eric Mickelson December 25, 2012 02:28 Only if you remember to seal the USB port. It's poorly placed on the top of unit. A better design would have been to place the port on the bottom to prevent water ingress. I have had the unit completely fill up with water. It is easy to accidentally forget to seal the port to pop the rubber seal off while operating on the road. 0 Ecadji May 16, 2013 10:18 Even if you take care of sealing the usb port, when riding inthe rain and wet gloves it is impossible to be sure not to move it when touching the unit. 0 Chris BeHanna September 21, 2013 22:15 Is there a difference in water resistance between the SMH10 and the SMH10B? I have had two SMH10s lose their left channel when riding in the rain. The channel returns after the unit dries for a few days, but goes away again in the next rain. My son's SMH10 has even worse symptoms: the noise cancellation stopped working, and now the blue LED stays dimly lit even after shutting down the unit. I have an SMH10B, by contrast, that survived riding all-day in frog-strangling rain. My sample size is far too limited to be able to generalize, however. If there have been improvements that make the SMH10B more robust in the rain, then I'll be happy to replace my son's drowned, out-of-warranty SMH10. Seconded Eric Mickelson's remark about the poor placement of the charging port. Even when care has been taken to smooth down the cover, we observed during our recent trip that the passing wind can lift the cover up out of the port. At the least, relocating the port to the bottom or bottom/rear of the unit, so that gravity helps to keep water out, seems like a no-brainer. 0 Targabill May 16, 2014 12:37 Just got my SMH10.. Very first thing when i pulled it out of the box, Wow, the rubber plug is on TOP?? At least ship with some glad baggy thing you can pull over the top?? 0 Richardpgriffith July 29, 2014 15:58 I hit a huge rainstorm this past Sunday and the three friends I was riding with (all using SHM10's) all had problems from shutting off, giving false low battery warnings, turning on and off. Granted it was a very heavy rain that lasted at least 1/2 hour, but once the rain stopped, all three units started working correctly again. 0 Richardpgriffith July 30, 2014 15:41 My SMH10 has been acting funny since I got caught in a rainstorm the other day. I have two blinking red lights when I power up (50% charged), but then it says Low battery and turns off. I haven't tried charging it yet to see if that issue goes away but if there's an indicated 50% charge, why am I getting the Low battery message with the unit turning off?

The USB port cover is lacking in design. The rubber cover sometimes comes open. On a typical ride, I change the music quite a bit, (rotating the big dial), and I notice that the USB cover is always slightly open when I take my helmet off. The port needs to be relocated. My suggestion is to put it on the inside of the unit (male pin side), and then add a rubber seal (similar to the seal on the cradle that protects the pins from moisture). I charged the unit last night and it's not shutting off anymore so hopefully that problem is solved. 0 Lu Vencl August 01, 2014 14:44 Interesting suggestion on relocating the port. I agree perhaps having it on the lower side would be smart. To be honest I never covered the port unless it started to rain. So I've only had to seal the port couple of times so far. 0 Patrick Cafferky August 05, 2014 08:34 Just submitted a request for info as my SMH10B has stopped working altogether. There are signs of corrosion on the front star bolt head on the underside. No lights when on charge and no luck using system reset - simply a dead unit. Anyone had experience of this before and could anyone suggest any remedies? To be fair I am waiting for a response from SENA who I have only just informed and teh unit is approaching three years old and has had average usage. 0 Lu Vencl August 05, 2014 18:44 What hardware version? Is this the original one with the round charging plug or the newer one with USB port? 0 Patrick Cafferky August 05, 2014 19:50 The set I'm having problems with is the more recent with the micro USB (not the round pin connection). Of interest I first purchased a round pin unit before the hardware upgrade; I then bought the newer version to link up to my pillion. I have gone back to using the round pin unit that is working trouble free. I think there is corrosion inside hence the rusted front bolt; alternatively the battery has come to the end of its useful life. Any suggestions would help as I have a European tour coming up and need to have both headsets available. Thanks Pat 0 William Perry March 07, 2015 19:59 My friend and I bought thses devices when they first came out and they have been great except for two issues. One of the connecting pins broke off and I no longer could transmit. They are very fragile so be careful. The other problem that seems to happen to my device, is in the rain. If we get caught (who doesn't?) my unit quits transmitting. I have found the quickest fix is to stop at a restroom that has hot air dryers for your hands. Take the detachable part off youir helmet and then hold both under the dryer for three or four minutes. Then you are good to go. I have also recently tried using piece of Saran or similar and a large rubber band to keep the rain out. This also works but it does interfer with the jog dial and button a little. It would be nice to have a fitted thin rubber boot to put over the unit on rainy days. Better yet might be a shield that covers only the top. That would then allow access to the dial and button. 0 Apurmals March 25, 2015 11:36 My first unit "crapped out" when I got caught in a "frog strangler". Sena gave me excellent customer support in order to try to fix the problem. My unit never dried out and would not turn on. Sena finally replaced the unit under warrantee. I decided that the design (charging port on top) is flawed so I now carry a roll of electrical tape with me when I ride. If there is a chance of rain, I tape a piece (enough to cover) of electrical tape over the rubber charging port cover. I've never had a problem since. As for the connectors, a light coating of dielectric silicone grease on the connectors (jog to base) has kept my Sena working in the rain. Hope this helps. 0 Targabill March 25, 2015 11:59 Doesn't SENA see all these comments and realize they product is FLAWED ?? Have to use electrical tape, glad bag, seran wrap... when it rains.. come on, we ride getting caught in the rain happens, 0 Alexis Casazza May 18, 2015 03:47 My poor SENA has survived 2 different rides (both over 150 miles) in down pours and 1 accident that totaled the bike, riding suit, boots, & helmet on the side where it was attached. I agree the port closure cap is located poorly and the cap/closure should fit tighter. SENA are you reading these comments? 0 CHANDLER, BRYANT L July 21, 2015 01:34 The problem that I keep having is that the rubber cover keeps coming completely off and I have to try to find it. Now it's completely lost! 0 Psandee September 07, 2015 18:12 My SMH5 is also showing some malfunction since it got wet in a mild rain. It turned off itself and when i turned it on it was working fine but then again it turned off and it dint turn on again :( Waiting for reply from Sena... 0 Iantate September 11, 2015 10:37 My SMH10 has stopped working after being out in a rain shower. It too turned itself off ( she very nicely informed me that she was carrying out a factory reset and then shut down - never to start again) I also am awaiting a response from Sena - how long does one normally have to wait for a reply from them, as my wife and I have a trip planned next week, where we would be expectng to use these, but it now looks like I am am going to have to spend more money on an alternative set of intercoms ! 0 Reubinthornton September 14, 2015 17:14 I rode in the rain, no issues. Got home and about an hour later connected to USB charging cable. Couple of hours into charge I noticed the charing indicator was not lit. I shook the cable, light came on. I reached to check the unit connector, it had melted and stuck to my fingers, burning 2 of them. I called Sena today after an email and was told: a. SMH10 is NOT waterproof, it's water resistant and the SMH manual states to not use in the rain. I asked the TechRep "where" in the manual and he basically told me to find it myself. I did find where the manual states the SMH is water resistant, but NO WHERE does it say DO NOT USE IN THE RAIN.... b. My unit is out of warranty and the only help TechRep could offer would be transfer me to the Sales line. c. The TechRep was indifferent about the issue as it was caused because I road in the rain. Sena.jpeg 0 Jihelle October 16, 2015 22:48 Whatever Sena says, the SMH-10 is NOT water resistant. Mine (bought in September 2014) stopped working properly after a storm last August and started working again after the Sena Help Desl advised me to do a full factory reset. But two months later --and after numerous "factory resets"--, the SMH-10 behaves erratically and doesn't hold the charge for more than a couple of hours. My advise is to place it in a waterproof location as soon as it starts raining...or go buy something else. 0 Brian Diver October 30, 2015 05:05 Well I must be doing something wrong as I've ridden in all sorts of rain with mine and for hours and hours without a problem. I just make sure all the rubber seals are tight and head out. Living in the Pacific NorthWET this is one of the reasons I chose this unit. I better go knock on wood! ;-) 0 Jihelle December 21, 2015 01:56 Well, I must say Sena is standing by its products !!! They've replaced my defective unit even if the problems started a month after the one year warranty had expired. They didn't tell me what the problem was though and whether it was related to some water getting into the unit but I really appreciate they stood by it. Thanks ! Article is closed for comments.
