A poorly fitting helmet may not only be uncomfortable, more noisy and may move around when riding if too big or give headaches etc if it is too small, it is also dangerous. A helmet simply will not protect or perform as designed if the head inside it is not snuggly fitted against the impact absorbing material inside the shell. In the Youtube video below I’ve included video taken with the Sena Prism and the 10C Evo so you can make a direct comparison. The easy thing to do would have been to wait for perfect conditions and filmed the spring countryside bathed in warm sunshine, but that isn’t the real world. Childrens helmets are available in a variety of sizes depending on the Manufacturer, but they are generally :

I can’t think why you might want to exclude the speedo from your video in favour of more sky, but if you wish to, the option is there. Sena 10C Evo Tech Specs I was just about to mitigate this crash waiting to happen by buying a Sena 10C Evo when I was assigned the job of reviewing that exact model of communications device with an integrated still and video camera. So, I won’t be doing that stupid, one-handed, distracted photography anymore, and you won’t have to either if you buy yourself a Sena 10C Evo. The camera is the reason to get this Sena Bluetooth unit. If you don’t want to take pictures or shoot video while riding, there are many other great Sena units to choose from. Sena Camera App support for a live preview of the camera, manage videos on the microSD card and change camera settings Minor bug fix with the Mesh Intercom button being disabled on the Sena Motorcycles App after activating the voice dialer using the buttons on the headsetThe camera quality is much better than expected, bearing in mind it's not an action camera like a go pro, it's still really good. I also love how my music seamlessly blends in with my videos. The Sena 10c Pro is equipped with an upgraded 2k camera, able to shoot in crisp QHD, with a resolution of 3.7 MP (16:9) and a wide 135 degree field of view. The 10C Pro also features Smart Audio Mix, which mixes audio from the intercom and music from your smartphone straight into your videos.

Capture video in 4K at 30 frames per second or take photos in still shot, burst, or time-lapse mode. The camera button allows for simple one-touch recording while Voice Prompts keep you updated on the camera's progress. With video tagging, you can save important events from a continuous loop of video recording, instantly creating highlights. As for storage, the 10C EVO accepts MicroSD cards up to 128 GB. That said, the important part – the memory card – is easy to access. Transferring your ride videos doesn’t mean having your helmet on the desk next to you. Dear Sena The 10C EVO’s compact, aerodynamic design is optimized for helmets as it hugs close to the outer shell. This results in reduced wind resistance and noise, improving your audio experience. In comparison to other similar camera systems, the design is slender yet the performance excels where it matters, with up to 20 hours of talk time and 1.5 hours of video recording.

If you are generally happy with the fit, leave the helmet on for a good length of time to ensure it is not pressing in places that are not immediately apparant. If a helmet is really pressing on your forehead this can sometimes cause a headache over time so it may be worth trying another size or brand. Some Brands have specific Medium sizes, for example Roof, which can give a very accurate fit if you are that size, for example : The installation of the speakers and wiring harness are straightforward. I used the boom mic for the HJC modular and the wired mic for the Klim full-face off-road helmet. I did have a little trouble with the harness connector that connects to the 10C Evo unit from the mic and speaker wires. I was overthinking it.
