    Hey Dennis, your problem is on my list of things to hopefully accomplish when I get mine hooked up, lol. My Blackberry had a voice command option where it listened for your voice then asked you to say a command. Is your Nexus like that? Will it allow every app to work with that? Sorry, not helpful, but hopefully an option can be found.

    FWIW, voice dialing works fine on my Blackberry.

    Yes..the Nexus can do almost everything by voice command.. I rarely type anything and most everyday activities are via voice command (set alarm, send text, send email etc.)..
    In addition to that, I use a motorcycle app called EMFB that can do everything by voice commands (maps, navigation, weather, NOAA emergency alerts etc).

    So yes, being able to "talk" to my smart phone via the SMH-10 would be great but sadly it does not work for any of that.
    Yes it works fine for voice telephone but that is a completely different subject.

    Just curious, what happens on the Nexus when the "phone button" is pressed on the SMH10? Does it start up any kind of voice dialing app or bring up a list of programs that might do voice dialing?

    I think I gave you the wrong impression... First of all I am talking about earbud headphones, not earplugs! And the reason I like earbuds is I use the noise-isolating kind so it blocks ALL the noise. More volume was not my question.

    And I realize there is no hack-free way to switch between speakers and earbuds by just plugging in earbuds to turn off the speakers. I really want both.

    What I was asking was, out of the various hacks people have posted, is there any consensus on one that is reliable, relatively safe on the equipment and proven? I'd be willing to try it. Also need a link please, THANKS! This would be the perfect combination for me.

    Ok I found the summary post on this item HERE. There are 2 variants of the Hack of the standard clamp kit to allow you to use earbuds (or speakers too, ideally):

    1. Use the Aux In port and re-purpose it as an Earbud Audio Out port by cutting traces, soldering and putting a 75 ohm resistor in series. As the mod proposes, you would never have the speakers connected.
    If you did connect the speakers, they would always be ON even if the earbuds are plugged in (unless you got creative with a 2nd jack or switch). You could easily hard wire them to either 0 ohms in series (normal volume) or 75 ohms or a second middle size resistor even.

    2. Use an external jack that you supply so it is a double pole type, meaning either one or the other is connected. He mounted it to the helmet itself (you can't easily take off the clamp kit now) or you could use a different inline jack (I'd have to source one). And you should probably deal with needing a bigger inline resistance for the earbuds, which he didn't do.

    I DO want to ideally have speakers working UNLESS I plug in the earbuds, otherwise I would just buy the optional earbud clamp kit, but this is the whole point - to have BOTH options.

    However, the earbud clamp kit from Sena has 75 ohm chip resistors soldered onto the board already, so it might be a third option:

    3. Buy the earbud clamp kit and modify the internals to pick off the R/L signals BEFORE the 75 ohm resistors to connect the speakers to. The easiest would be to run a pair of wires out for the speakers and then add an inline jack you could tuck into your helmet liner, and add a plug on the speaker wires, then you would plug in the speakers only when you want them on. This gives you 0 ohms in series to drive the speakers OR 75 ohms to drive the earbuds (standard wiring in the unit). Optimal impedance matching hopefully.
    Another clean but more difficult option would be to hack the traces and re-purpose the Aux In jack to be Speakers Out (and connect to the top of the resistors, so they are not included).

    Of course this is all in theory as I have not bought anything yet. Below is a borrowed picture from inmate genka from his mod thread, showing the stock, unmodified earbud clamp base. I'm guess that the resistors are at the top, R1 and R2:

    So my question is... anybody have experience with these? Improvements? Did you use different series resistance for the earbuds vs. the speakers? THANKS!

    The phone "wakes up" (for lack of a better description) and prompts me..
    ..two things happen..
    the phone pops up this message on the screen (see below) and simultaneously it speaks the the same thing..

    [​IMG]

    But that is only for telephony mode..
    .. in any other speech input mode the mic on the SMH-10 does not get connected to the phone.

    So basically, a different program is needed that defaults instead of that basic dialer one or a way to configure Google Now to be prompted by the Sena BT headset button instead of the voice dialer? I assume you've looked into that?

    I just did a bit of searching and it sounds like this is a pretty common complain on various Android phones about not being able to do a lot of voice control options via a BT headset.

    That's basically the issue. The Android OS doesn't have the 'smarts' built-in to route the various requests to the right app, and activate the BT mic when needed. But there may be hope! Check out this app I just came across:
    https://play.google.com/store/apps/details?id=com.lukasoft.android.voicecontroltest (Test Version)

    https://play.google.com/store/apps/details?id=com.lukasoft.android.voicecontrol&hl=en (Full Version)

    You need to be on Jelly Bean for it to work, though...

    good info thank you!

    and / but

    ..and
    My phone is 4.1.1 and, as we've been saying, it does not work on that.

    ..but
    My Nexus tablet is 4.2.2 and guess what?
    .. it works .. but in typical Android fashion.. "sort of".

    The "but sort of" is that it seems like it works only one time.
    I fired it up and and it worked the first time and I was VERY happy..
    .. then I tried a second command and it did not work.

    Then I exit my app and open it again and it works.. ONE TIME.. and then it no longer works..

    typical android.. half a##ed..

    I'll try some of the other links later..
    .. have to run some errands now.

    Thanks for all the help! .. seems like it might someday actually work as expected..

    I just got a new SMH10. and when i go to click it into the helmet mount, there really isnt a click? i can pull it on and off without pushing the little lever thing. is this normal? im afraid that it will just fall off?

    No, it is not normal and yes it will fall off. Until you fix this.

    The most common cause is the clamp mounting screws being over-tightened and/or a helmet shell shape that is too curved for the mount to work properly.

    If it's just the former, loosen 'em up until they are just tight enough to prevent the mount from slipping. If it's the latter, think about alternate mounting position or method.

    Forcing the SMH-10 until it clicks will eventually crack the mount.

    Ok so no response... so... I'm guessing my "earbuds" question got too detailed and off into "corner case land"? :lol3

    My goal is to have only one ON a time: Either the earbuds (for long trips) OR the speakers (for quick around town trips). But NOT both at once.

    Why? My personal preference is that I don't like the idea of the speakers always blaring when the earbuds are in for long trips. I don't want to blast my music or phone conversation out to the world - either my passenger, others when in a group, or the general public, when stopping at stop signs or trail side or whatever. (Also when on a phone call I want to keep it private, but let's don't this preference). Ok, got that over with, now to the question...

    Let me ask this. Anyone that has tried earbuds vs. speakers (stock or otherwise) how far apart are the volume levels if you don't move the jog dial? and did you use any resistor in series in either case?

    You may think "just turn down the volume" when you switch from speakers to earbuds but I'm trying to protect what's left of my hearing...

    Maybe I'm too hung up on this issue but if you run both the earbuds OR the speakers at the same signal level (same resistor) then...

    This is the way I see the issue:
    I put in the earbuds, put on the helmet, insert the earbud jack, THEN turn on the unit and it BLOWS my ears out before I can turn down the jog dial... because the volume is too high from using it previously with the speakers. I've done this too many times in my life and am trying to protect my hearing.

    Is this non-realistic ? I guess I'll find out soon as I'm going for a modified Hack of the standard clamp when I order it.

    If you always use the same earbuds, why not build the extra resistor into the earbuds plug or cable?

    Another option might be an in-line volume control? Have one on each wire (earbuds and speaker), adjust as needed for each, and when you get it balanced out right, put a few wraps of electrical tape around it so the dial doesn't move, tuck it up in the helmet, and from then on out just use the 'main' volume on the SENA.

    Thanks, those are good ideas. I had kicked around both, but seeing your posts together gave me an idea.. I wrote it up but think it is too long and maybe too off topic, so I decided to keep it too myself :lol3

    Ok I think I'm just going with the earbud clamp kit and earbuds for starters. For speakers, my helmet does not have room for the massive (and $80 !) Tork XPro so I'm going to buy another Sena universal mic clamp kit and cut off the speakers then wire a plug on them. I know I can just buy the Sena speakers but for $6 more you can get the whole clamp kit and I can always Hack it later if I want and have a 2nd base. When not using the speakers, my helmet has a perfect spot (between side and rear liners) to insert the little 4" cord and plug at the end of the speaker cable, so no problem there and it won't dangle.

    If the speakers are not loud enough when connecting to the earbud clamp (due to the 75 ohm series resistors in that clamp), then I'll deal with that later. If so I plan to open it up and short across or otherwise bypass those resistors and that will fix the speakers. But then if the earbuds are too loud AND too volume sensitive (like if the first few jog positions give you: Faint, Loud and Bloody) I'll deal with one of several ways to insert a resistance inline, either inside the clamp kit by re-purposing the Aux In to be Speaker Out, or by an inline resistance outside of the clamp kit on the earbud line.

    NEXT PROBLEM:

    This is not strictly a Sena problem per se... so PM me if you have an idea.

    This leaves the nagging issue of earbud cable management. The earbud clamp kit has a nice coiled cable that I think will help a lot on that end and prevent snags yanks. But what about the 2 wires coming down from your ears? I've tried lots of things but eventually they snag and sometimes rip an earbud clean out of my helmet (someday that will break an earbud in the middle of the Baja)... so what to do? Any good threads on this? I've looked.

    I currently use this scheme: I epoxy'd a small powerful 3/8" neodymium magnet to the underside of my helmet on both sides near the front, then wrapped very fine wire around my earbud line. After I put my helmet on I just set the wire near the magnet and it holds it out of the way, but any real snag just releases. Kindof extreme and is only an 80% solution.

    Ideas?

    One more thing, in addition to the Boostaroo, I found this additional coiled inline volume control cable WITH COILS on it from an amazing site somebody just posted called PlugUp.com that also has short plain 3.5m extension cables 4", 12", 24" long) that you could cut in half to get male or female ends, both 3 conductor (for stereo) and 4 conductor (for iPhone/iPod control).

    Thanks for everyone's ideas, I'm placing my Sena order today with senor Adam at RocketMoto. Support your fellow inmates AND be sure you have a warranty! The Sena website is very clear about this...

    I use a set of SURE earbuds that have a short cord on them. They come with a long cord for attaching to other units but they are perfect for the SENA unit. Before I had those I just left the cord loose infront of me.

    I have a question about the SMH10. Do you leave the SMH10 on the helmet mount all the time or do you take it off sometimes. If you don't have it on the helmet would the open connection of the headset be ok if it rains?

    Getting water in that connection is only a problem if you're using the headset at the time - DAMHIK.

    In answer to the original question - Yes, I take it on and off all the time. I don't charge it on the helmet.
