Best helmet EVER!!!!
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.

Love, love, love this helmet
I love this helmet. Purchased one for me and one for hubby. We ride quite often and these helmets allow us to talk to each other. I thought there would be a lot of wind noise but there isn’t. You can hook your phone to them as well and make calls or listen to music while you ride. Highly recommended. High quality and great functionality. Easy to set up and use. Good value for the money.

Super helpful!
This has been great for riding with my boyfriend! The person in front is able to call out stops, things on the road, etc. this should be essential for riding in groups imo!!

Great for communicating
Bought a pair of these so my wife and I could converse while bike riding. They work great and we are very happy with them.

Warranty Replacement
Unfortunately at this time they are having issues with the C1 helmet Bluetooth technology. For warranty you will need to send the defective unit back first (paid by consumer), after they get the defective one back they will go ahead and send the replacement. So if you’re in a position to be without a helmet for several weeks and don’t mind spending the money on shipping you’ll be fine. I would look at other better options out there.

Great for riding with a friend
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.

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).

Wir haben zwei Helme gekauft und sind sehr zufrieden. Die Verständigung untereinander ist gut und erhöht die Verkehrssicherheit enorm.Auch wenn wir mit Navigationssystem (Handy)gefahren sind konnten beide mithören. Der Preis von 69 € pro Stück war echt super.
