I have the same sena unit and have one installed on my motocross style helmet and one on a full face helmet. I also have loud pipes. I wear the motocross helmet and my daughter wears the full face. We are able to listen to music and talk to each other and can hear both fine at highway speeds. However it took some adjustments of the speakers in the helmet to where they were positioned so the music goes straight to our ears.I'm a new rider on a 21 Scout with about 1,400 miles so far. Loving it!
I have a full face helmet and I installed a Sena 5s bluetooth system for music and navigation. Navigation audio is fine. Music is VERY low. I'm into tech stuff and I've done the basics of making sure my iPhone volume is max, removed any high volume protection limitations on iPhone, turned Sena 5s all the way up, used their EQ to make sure I boost it, I have EQ off on the iPhone as I should, and I contacted Sena who told me the most basic stuff despite all this same info (did I turn the volume up?--seriously). I also played around with speaker location. Not much improvement.
From all the boards I've read, plenty of other Sena users have this same problem.
I tried wearing AirPods. I don't like this option for various reasons and would not use this route.
I love listening to music. Is there any way to boost the audio on the iPhone or the Sena to improve the music? Or better headsets out there someone could recommend?
On my helmet I had to buy some sticker Velcro to get the speakers at the best position, it took a lot of attempts mostly because the chin straps were in the way and would knock them out of position when putting the helmet on or off. I also had to get some of those metal sheets for mounting a magnetic phone case to hold the straps in place so they didn’t bump the speakers out of position anymore. My helmet wasn’t the best helmet for the job. When I got the sena s5 I got another helmet that also wasn’t best for it because it converted to a 3/4 and I had to position the speakers so you could still convert the helmet without being in the way of that function and thus the speakers couldn’t be where I needed them to be for best audio results, as far as volume went, it was installed by the employee but I couldn’t hear anything on the highway so I readjusted them to the best I could with that helmet and ended up getting it right but the helmet was a size too small so I got my current helmet and we’ll it was a chore to get dialed in.
My daughters helmet I didn’t have to mod anything i just had to reposition the speakers for the best audio for her. If I put her helmet on and leave the speakers as is then the audio is quieter for me because it’s not aimed at my ears like I need them to be.
so long story short you got to move the speakers around till you find the best position for your ears and not all helmets like head units. Even the ones with cut outs built for them you sometimes have to mount in a different location for your ears. Once you get it dialed in I promise you’ll be able to hear your music at speed with loud pipes no problem. Of course full throttle it’s a little quieter but you can still hear the song and lyrics and know what you’re listening to. Good luck!
