    Is it possible the 74 ohm resistors are integrated into the earbud cable? BTW, the speakers are supposed to be louder than prior design... Which is good when earPLUGS are in use. Anxious to try this out.

    Yeah... Between that Sena extension cable and your headphone wires, that's a lot of wire tucked up in your helmet...

    More like the long length of the cable IS the resistor.

    My wife and I have been riding with the Sena SMH-10 system for about 16 months now. It's awesome. We bought the kit for folks who ride with ear buds (no speakers, just jacks for our "Arizona Al" custom earplug speakers), and that's been the perfect solution for us. It's an enormous improvement over the Scala system and an even bigger improvement over the Autocom system we used for about four years before that. The only benefit of the Autocom was the ability to listen to the same music. I guess Sena has a new module to make the possible (SM-10), but we haven't tried that yet.

    I can't imagine why anybody would want the speakers AND the earbud jack. If you ride with buds/plugs it's easier, cleaner and simpler to the get the bases with the ear bud jack.

    For short trips in town, I prefer the speakers and not messing with earbuds. However if I'm going to be jumping on the interstate or riding all day, then the earbuds are nicer to use.

    +1. have used the headset speakers with ear plugs and I can hear. But for me the sound is muffled too much. Would rather wear custom ear phones that block noise but give me the music fidelity I require. I'm with the earlier post, why not a 3.5mm jack on the base and let the customer decide if they want to plug in the stock speakers versus their own headset.

    The more I look at this new design, the more I don't understand it. Especially considering they had a thread on the Sena website forum asking for users input. They had a chance to make a very useful addition to their product and they fucked it up. I think this new clamp is useless.

    I think many people want a single clamp that allows you to sometimes use speakers and sometimes use headphones. This would be accomplished by having the speakers wired to the clamp all the time and having a 3.5mm jack built in to the clamp that would defeat the speakers when headphones are plugged in. Why is this so hard?

    With Sena working on a new design and taking feedback on their forum I had high hopes, but I am disappointed by this new design.

    What they ended up with is a "universal" clamp that allows you to set up your helmet with EITHER the speakers OR with a headphone dongle. This design is not clean for switching back and forth. Yes, you could unplug the speakers and then plug in the headphone dongle. But that is clunky.

    As mentioned above, I want speakers for short trips around town and the ability to plug in my ear buds for longer/highway trips. I don't want to have to fuck around with unplugging the speakers.

    I am mostly disappointed because even Sena listens, it would probably take a year for them to release a proper "dual function" clamp.

    As mentioned on NUMEROUS occasions. Speakers and earbuds have different impedance's. Hence the need for the 75 Ohm resistor when hacking the old clamp to use earbuds.

    Would be nice if they would make the plug in for the ear buds base one that goes into the unit and not the extension that is currently there. That would stop the issue of that piece breaking.

    I have not read all of the posts here so this problem could have been mentioned before.

    I have snapped off two of the mini-usb charger port covers when I grab a pull out the charger plug. The rubber cover lays alongside and I get both.

    Rocket Moto sent me one but they did not have another. This is not a part that Sena sells.

    At Adam's suggestion, I called Sena on 866.300.1235 and they are sending me two more covers at no charge.

    Nice! :thumb

    I will try and be more careful!

    Follow Up: Received three of those covers in the mail in two days at no charge!

    While it is true that earbuds typically have higher impedance than speakers, mainly due to the very small moving coil, the biggest difference is the required POWER. Sena took an odd approach in the original configuration using speakers that were nominal 32 ohm transducers, 38mm, rated at 200mW I believe. My aging Etymotic ER-6i earbuds are nominal 16 ohms. Kinda backwards, right! This makes those resistors even more essential.

    I've recently purchased the Sena SMH10 and for motorcycle communications it's been great thus far. I can hear my fellow motorcyclists very clearly and it's great :D

    I do however, have a major problem. My Windows Phone 7 mobile uses Navigon for turn-by-turn navigation. This is all working fine when I'm not talking to someone else through the intercom, but when I talk to someone the turn-by-turn messages do not come through. I suspect this because it's coming through A2DP bluetooth and not HFP. I couldn't find a way to change the priority in the Sena SMH10 either :(: Is there any way I can actually fix this?

    There is no way to change the priority on the SMH-10, but if you want to spend some more money [g], the SR-10 hub uses HFP and would interrupt an intercom conversation with directions.

    You could hardwire the phone to the SR-10 and it would definitely do this (I use it for radar and GPS), but may also be able to pair the phone with the SR-10 and still have it be a higher priority than intercom, but I haven't tried this.

    I thought so. Spending 180$ on the SR-10 seems a bit excessive for my purposes, for that money you can buy a navigation system already.

    There is no way to have A2DP from mobile phone go above the intercom without the SR-10?

    The SR10 would solve your issue, but as you said, that's a pretty pricey alternative. There is no way to change the priority of A2DP on any of these systems that I know of including the SMH10. All of the priority is set in the programming of the headset by default.

    There might be another option though. I'm not that familiar with windows phones and if you even have this option, but on Android, there are apps you can download called BT to Mono or some effect to that. Basically, what they are really meant for are to use with normal BT headsets that don't have A2DP and therefore they route all the BT audio over the mono HFP connection. So in this case, I would expect it to route GPS navigation over the HFP connection instead of the A2DP connection. Since HFP is a higher priority than intercom, it would interrupt or maybe even "mix" in with your intercom audio. Now the one downside to this is if you are actually listening to music from your windows phone, it could affect your music and send it over the HFP connection? Some apps/programs might be better where they give the option of what application you want to send its BT audio over the mono connection?

    Here's just a small example of some of the Android apps that do this. There's plenty more out there for Android.

    First thing I would think about is using the phone for navigation.
    If you are in some large tract of state or national forest (we are adventure riders right? :D) and you end up so far out you don't have any cell service, does you phone navigation still work?

    If no, you have a problem that can only be corrected by getting a GPS with maps in memory. Then get a GPS that does some kind of bluetooth. But before buying, ask here if it will work :). Plus GPS opens up another aspect where you can layout your own routes taking the roads your phone would try to avoid

    I have a Garmin Montana which does not have Bluetooth, so I have it hard wired to the SR10.
    Also at times I ride with other people who use FRS or GMRS walkie talkies (and one buddy is an Amateur radio operator like myself) so I hook a walkie talkie radio to the SR10.

    Many phones have their own built in GPS sensor so as long as the maps are stored locally on the phone, there's no issue if you don't actually have phone service. In fact, I know some people in the dualsportmaps.com thread buy Android phones just to use it with this software and don't even have service on them. They just download the maps locally to the phone while on wifi.

    Myself, I still find a large advantage to using a GPS for route planning over a phone, but there are some great programs out there for GPS navigation using different programs for phones. Dualsportmaps.com is definitely one of them.

    Thank you for your suggestions. I've found those apps to. On my other Android mobile I've tried using these apps to no avail as what they do is constantly open the HFP bluetooth channel resulting in an unusable intercom :cry One of the apps had a 'dynamic' mode to only open the channel when it detected sound, but the delay was too long (most of the turn-by-turn was gone already) and it didn't close the channel anymore.

    It's a shame really that the Sena SMH10 doesn't support changing the priorities, I never listen to music anyway and it would be awesome for using mobile phones for navigation. A cheap solution, navigating purely on voice works pretty well in my opinion, it would be awesome if I could still hear it when I talk to my mates ;)
