Sena C1 Smart Cycling Helmet

My wife and I both have this helmet and we love that we can listen to the same music and communicate with each other. Makes for a much safer ride.

Got a medium for me and a large for my husband. I had my doubts that it would fit his big head but they are very adjustable. Price is a bit steep but I saved by buying used. Sound quality for calls is excellent; somehow there is no wind noise, unlike what I've experienced with my regular Bluetooth headset. And being able to talk to my husband while we're riding has been awesome both for keeping together and safety. When I ride alone I listen to podcasts and music and appreciate that I can hear traffic sounds fine along with my music. And I appreciate the flashing light on the back for safety. Pairing was challenging at first, probably because the helmets were used so they had probably been paired before. The directions were not the best; there was no mention of how to pair a second device which would have helped, but I figured it out. Once we got the intercom feature figured out we were sold. My un-techy husband even managed to answer a phone call on our first ride and was quite happy with the call quality, as the other party was not even aware that he was on a bike. Only 4 stars because of the poor directions and cost, and also because at this price they should be MIPS. But I would definitely buy again.

Works great. Charges last for multiple long rides. Fit and adjustability, great. Greatly enhanced our bike rides, no more shouting. The only thing that could be improved was if they created a visor for this model, even if it was an accessory that could be bought later.

They look very sleek and fits perfectly on our head. Very lightweight. The quality of the helmet is top notch. Easy to connect to your Bluetooth and has many cool functions like the speaker to listen to music, intercom with the press of a button and flashing lights for day, nite or steady. We absolutely love it. Put it in the cart, a great value for the money.

Don't waste your money with this vendor. Very poor instructions on pairing helmets. Extremely poor customer service for defective finish on helmet. One week after the return deadline, the finish started to peel off the top of the helmet. We contacted Amazon customer service and Kalandar was able to get an exception to the return processs (see note below). However, it's past July 9th and still no word on the replacement helmet or return authorization. Kalandar is a super star and Sena offered zero customer service. UPDATE 8/15/25 - Amazon Customer Service ultimately stepped up and resolved the problem with an exception to the return policy and refunded the purchase price. Bottom line - Amazon Customer Service saved the day, but I stand behind my comments that Sena does not provide adequate customer service and my recommendation is to not purchase products from Sena. Hello Mark , This is Kalandar, the representative who assisted you earlier. I am very much grateful for that kind and warm approach you gave on the chat. As per our conversation, I have successfully added this request to seller and as an exception they process this and get back to you via email with confirmation within 48 hours that is on July 9. I hope my efforts to resolve your issue have been satisfactory. Thank you for Calling Amazon Customer Service. Have a great day ahead! Best regards, Kalandar Amazon.com

El audio es muy básico para escuchar musica pero funciona bien.

This helmet is a great addition to our bike rides. It allows us to carry on a conversation without pressing buttons or hearing a lot of static. We were about to use these right out of the box. After using them for 3 days we put them up in the closet until our next trip. They would not turn on nor show they were charging. We researched what to do and found that a fault reset was needed. fAfter this they worked fine. We ordered a medium and a large based on the suggestion that they run small. I do not think they run small. I could have used a small, but I can easily put a stocking cap or baseball hat on underneath if it is cold. Easy to use and comfortable. Keep your instructions handy if you od not use them weekly.

We were trying to use our phones to communicate while riding but it was a dangerous distraction and the call kept dropping. This is the perfect solution. We love them and recommend them 10/10.

I really like the concept of having a Bluetooth intercom built into a bike helmet, and the C1 does have some strong points. The intercom works well, and being able to talk to each other while riding makes commuting much more enjoyable and convenient. Setup is simple, and the sound quality is decent for everyday use. Unfortunately, the speaker placement is a weak spot. The speakers are attached to the chin strap with thin plastic, which makes them very prone to damage. I bought two C1 helmets, and in both cases the speakers broke after only a few short commutes. On the bright side, Sena has other helmet models with speakers integrated directly into the helmet shell. These look much better protected and may be a better long-term option.

I decided to get this helmet as I wanted to listen to music whilst cycling and maintain a sense of my surroundings (having earphones in is just not a good idea, it's incredibly unsafe). The speakers are located on the strap, so they are positioned near your ears but not on or in them; surprisingly delivers satisfactory results. Connecting to my phone was very straightforward and I have also linked it to the app where you can quickly turn on the LED on the back of the helmet (this is another nice feature to have). I can't comment on the intercom feature as I don't have anyone else to cycle with who also owns this helmet, but if it's anything like their motorcycle intercoms, it's safe to say it should be decent. And finally, this helmet is very comfortable! Easy to adjust, has a soft chin cushion and is super lightweight. All in all, I'm very pleased with my purchase.

Makes sound and protects my head

ich habe mir ein paar verschiedene Helme bestellt und dieser saß am besten von allen. auch der nervige kimmriemen verschluss war hier am besten gelöst. die app war schnelle eingerichtet. das firmware upgrade trotz Mac problemlos. es lassen sich wohl 4 gesprächspartner connecten, allerdings so weit kam es bei mir nicht. denn ich habe ihn wieder zurückgeschickt. weil das mikrofon vorne, oben am helmrand sitzt. ich bin kappenträger und wenn ich das hier täte (kappe plus diesen helm), dann würde der schirm der kappe das mikrofon abshotten. ich sicher einer der wenigen, die das machen .. ansonsten kann ich den helm sehr empfehlen.

J'ai acheté ce casque à la suite du renouvellement de mon vieillissant Sena X1 que j'avais globalement apprécié. J'ai changé du fait du vieillissement normal du polystyrène composant le casque, mais également de la batterie qui flanchait. Une mauvaise expérience au global: - les clips des oreillettes se sont rapidement cassés, laissant les hauts-parleurs en partie pendouiller et tracter sur les câbles des oreillettes, - par conséquence du premier point, le câble du haut-parleur a fini par créer des faux-contacts, rendant le casque partiellement inutilisable, - niveau égalisation, les hauts-parleurs ont beaucoup moins, sinon aucune basse, bien que ça n'a pas été le plus gênant car on s'y habitue, - les boutons à l'arrière du casque sont une catastrophe ergonomique: avec un gant en hiver il est très difficile de distinguer les boutons (il n'y a pas de bouton vraiment en relief pour se repérer, la géométrie des boutons est insuffisante), et le fait d'avoir les boutons à l'arrière rend la manipulation plus longue donc plus dangereuse, surtout sur une trottinette où l'équilibre est plus précaire et sensible qu'en vélo, - la fonction intercom multidirectionnelle ne semble pas exister du tout dans l'implémentation du micrologiciel, - possiblement une mauvaise compatibilité avec certains équipements bluetooth qui ne soit pas un téléphone (radio). À noter toutefois le point positif d'avoir les oreillettes plus proche des oreilles, on entend globalement mieux. Je vais tenter un SAV du produit. Mais il est clair qu'à ce jour la meilleure chose qui puisse leur arriver c'est un concurrent, car cette itération est vraiment bâclée. Il m'aura tenu 5 mois pour une utilisation globalement quotidienne (trajets domicile-travail).
