Worth every penny

I never thought I would spend so much on several helmets but after using 2 of them with my significant other and I, we bought more for the kids. The range is phenomenal if you separate out of sight. You can hear it clearly and don’t have to shout for the mic to pick up your voice. Can speak normally. You only pick up heavy cross wind. So if you’re traveling fast and turn your head sideways, or a strong sidewind. Which may sound bad but it’s not, testament to blocking out the wind noise so well for 99% of the ride. Battery life is great. We’ve gone out for several hours without ever turning them off. Which is surprising given how incredibly light and comfortable they are

Nice helmet, but there are couple of things you should know

Reviewed in the United States on December 22, 2023

Size: LargeStyle: R2 Bluetooth IntercomColor: Matte GrayVerified Purchase

We bought two of these helmets, and they are reasonably comfortable (as helmets go) and have a good intercom. I would have rated them at 5, but for two issues.

1) TL/DR their size guide is a bit on the small side. We used their measuring guide and came in at 23”. Based on their guide this is a medium. We could hardly get them on our heads and they were headache inducing. Therefore we had to go through the exchange process for a large. And even then we are opening up the adjuster about halfway.

2) TL/DR download the full user manual before you decide to load their mobile app. All of the information from the package talks about loading the app and using it to control and pair the helmets. All we wanted to do is pair the helmets. After loading the app and using it to look at the full manual we found that no app is needed to pair them. To us the app is useless. You can run your phone sound through the helmet, but music quality is very low. I would use earbuds before putting music thought the helmet, and my watch tells me when I have a notification. Perhaps if you want to talk on the phone while riding…

Extra note: The only way to update the helmet firmware is to use a PC. If you only have a mobile or tablet then you may be out of luck for firmware updates.

Bought 2 of these for wife and I - immediately allowed us to enjoy biking more than before, staying in contact during the rides and notifying each other of passing cars, clear roads, or bumps have made us both very happy. Also able to play music when riding alone. Helmet allows plenty of air flow, avoiding heat or sweat issues when on longer rides as well

Has transformed my commute

Reviewed in the United Kingdom on October 12, 2023

Size: LargeStyle: R2 Bluetooth IntercomColor: Matte WhiteVerified Purchase

I read the reviews and was a little uncertain whether to buy one of these helmets. I did a bit of research and this helmet kept coming up in the top 5 smart helmets. It arrived quickly and the set up was really easy. You don't need to use the Sena R2 app to connect to your phone. It connected via bluetooth very easily. I've mainly been listening to Radio 4, podcasts and audio books. I had read reviews which said people couldn't hear the speakers over the sound of the traffic or the wind. I live in central London and I've been cycling along really busy roads during rush hour and I can hear what's going out of the speakers perfectly clearly. I did receive a phone-call from my husband and couldn't hear him very well, but then I realised the phone volume for calls had been turned down.
There is a light on the back of the helmet which either shows solid red or flashing red. It works very simply by pushing the very obvious button. Below that button is the charge point. It glows red when it's charging and blue when it's fully charged (I read someone else's review that said there wasn't a light to indicate it was charging so perhaps they've made an improvement to the helmet since then).
Overall, this has been a great purchase. So much so, I've bought my husband one too.

J’ai acheté ce casque en février, j’ai attendu quelques sorties avant de mettre un avis.
C’est un très bon casque, d’un point de vue sécuritaire, il est solide et équipé d’une lumière à l’arrière.
Pour ce qui est du Bluetooth, je l’utilise principalement pour avoir un fond de musique en balade. Il possède une très bonne autonomie, je ne suis jamais tombé en panne de batterie sur des sorties de plusieurs heures. Jamais aucun problème de connexion non plus. Je recommande ce casque.

Sena R2/M1 (erst ohne EVO) - jetzt umgerüstet auf M1 mit EVO!

Reviewed in Germany on May 21, 2023

Size: LargeStyle: R2 Bluetooth IntercomColor: Matte BlackVerified Purchase

ACHTUNG: LANGE Rezension, da einige Beschreibungen zur Handhabung und Planung enthalten sind , die wir so nicht direkt gefunden haben - für Interessierte als Information.

Fazit vorweg: SEHR gut, wir sind begeistert und absolut zufrieden!
(EDIT: Mit EVO - Stand 26.8.23:
Wir haben nach knapp 5 Monaten bedauerlicherweise eine Veränderung zu verzeichnen: Die Verbindung ist nicht mehr stabil, es gibt erhebliche Störgeräusche. Diese lassen sich IMMER durch Auskoppeln des Masterhelmes oder spätestens durch Aus- und wieder Einschalten desselben beheben, aber das ist während der Fahrt schon nicht ganz ungefährlich, an den Knöpfen derart lange rumspielen zu müssen.
Auf der letzten Fahrt hatten wir auf 57km acht Unterbrechungen, das wird inakzeptabel.
Da sich die Gruppenkonstellation sowieso geändert hat - wir sind jetzt fünf bis sieben Teilnehmer, Tendenz potenziell steigend - war BT aber sowieso die „falsche Entscheidung“, so dass wir den teureren EVO Helmen jetzt doch eine Chance gegeben und ein zweites Mal investiert haben.

Ersteindruck: Wieder extrem gut (ich melde hier nochmals nach ebenfalls fünf Monaten) - sogar besser, als ohne EVO (Tonqualität) - Der Abfall der Tonqualität bei mehr als zwei Helmen, wie bei den Modellen ohne EVO ist nicht zu verzeichnen! Des Weiteren entfallen (bei uns) die Übertragungen der Windgeräusche von den anderen Teilnehmern.
Das Handling ist - technologiebedingt - ebenfalls sehr viel einfacher: Die gesamte unten beschriebene „Planungsweise“ entfällt vollständig und kein Teilnhemer muss sich überlegen, wann sich wer einschaltet.
Doppel- und Dreifachklicks entfallen. Bei den EVO Helmen kommt auch die in der Anleitung versprochene Akkustandsmeldung. Der EVO helm gibt trotz Intercom Navigationsanweisungen des Mobiltelefons aus.

Die Helme ohne EVO werden wir wohl verkaufen.

Details (zu den Helmen OHNE EVO):

Dies ist unser dritter Versuch, eine Kommunikation auf dem Fahrrad zu realisieren.
Erster Versuch waren die kleinen, chinesischen Teile mit monauralem Headset. Diese waren in der Kopplung sehr aufwändig und haben sich so oft „verschluckt“, dass eine Anwendung nicht wirklich sinnvoll war: Fuhr mal eine(r) aus der Gruppe zu weit, flog sie/er aus der Gruppe oder es gab unerkärliche Verbindungsabbrüche. Beide Situationen waren ohne Aus- und Anschalten und erneutem Koppeln nicht zu beheben - Akzeptanz also nicht gut, damit Schrankware.
Zweiter Versuch waren „echte“ Funkgeräte. Hier natürlich die Verbindung ohne jegliche Fummelei stabil und die Entfernung phantastisch. PTT allerdings am Fahrrad eine Herausforderung - so dass trotz höherer allgemeiner Akzeptanz die generelle Nutzungshäufigkeit niedrig war und die Häufigkeit der Kommunikation mittels erhobener Stimme hoch. Das war nicht im Sinne der Anwender*innen, daher auch dieser Ansatz (für uns) dysfunktional.

Sena R2 nun scheint das „Richtige“.
Wie in anderen Rezensionen und auf YT beschrieben, ist die Qualität tatsächlich unfassbar gut.
Reale Straßenentfernung etwa 350m, im Wald etwa 250m - also für „gemeinsames“ Radfahren mehr als ausreichend.
Mit nach vorne gerichtetem Kopf selbst bei 50km/h mit Gegenwind keinerlei (!) Windgeräusch vom Gesprächspartner - die eigenen (Wind-)Abrissgeräusche am Helm stören wesentlich mehr, verstehen kann man sich einander dennoch (nichtmal maximal laut gestellt). Windgeräusche von Partner*in treten dann auf, wenn der Kopf nach unten geht (Blick auf die Füße) oder bei Seitenblicken mit Kopfbeteiligung - ab ca. 45 Grad Seitwärtsdrehung.

Etwas, das mir beim Kauf der Helme NICHT bewusst war, mich aber nicht vom Kauf abhielte: Wenn mehr als zwei Personen verbunden sind (das ist unser Anwendungsfall), wird die Telefonverbindung abgeschaltet! (Steht auch so im Handbuch - aber natürlich nicht in der Produktbeschreibung des Verkäufers).
Das ist für uns nicht dramatisch, für andere Anwendungsfälle / Bedürfnisse aber evtl. hinderlich.
Des Weiteren (für mich auch nicht dramatisch, hatte ich mir aber ebenfalls anders vorgestellt) ist aufgrund der Priorisierung der Anwendungen (Telefon-Intercom-Musik) Musik oder Stream vom Mobiltelefon dann und nur dann zu empfangen, wenn man Intercom ABschaltet! - Irgendwo im WWW hatte ich sogar einen Hinweis auf „gemeinsames“ Musikhören gesehen oder gelesen - das funktioniert definitv (auf den hier liegenden Helmen) nicht.

Einen Haufen Frust spart man sich beim Paaren der Helme und in der Verbindung der selbigen bei der Anwendung, wenn man das Prinzip verstanden hat und das Ganze ein bisschen plant …
Positiv zur beurteilen ist die BT Verbindung und der zugehörige Speichermechanismus der BT-Verbindngen in ihrer Flexibilität besser als erwartet und besser, als im Handbuch angegeben! (s.u.).

Wichtigster (im Handbuch auch so angegebener, aber wohl häufig übersehener) Faktor: Im Modus „Kopplung Intercom“ jeweils nur die Mitteltaste EINES Helmes drücken und LÄNGER warten, als man so vermutet….
Zweiter wichtiger Faktor (Planung): „Der letzte wird zuerst bedient“ - Handbuch Kapitel 7.2. Das bedeutet, dass vorher überlegt werden muss, wer beim Einfach-, Zweifach- oder sogar Dreifachklick erreicht werden soll.
Dritter wichtiger Faktor: Handhabung - Wie schnell ist ein Doppel- oder Dreifachklick? Das hat zunächst für die größte Verwirrung und die höchste Rate an Nichtverbindungen gesorgt: Die Geschwindigkeit ist geringer, als (von uns) erwartet - es müssen zwei (drei) aufeinanderfolgende Töne hörbar sein - dann hat man die richtige Frequenz getroffen.
Vierter wichtiger Faktor: Jeden Helm mit jedem Helm koppeln!

Laut Anleitung ist es sinnvoll, einen „Masterhelm“ zu definieren, von dem man ausgeht. (A)
Wir sind eine Vierergruppe - zwei Ehepaare - und ich möchte final erreichen dass jedes Paar auch allein fahren kann und mit „Einfachklick“ jeweils verbunden ist. Aktuell haben wir jedoch nur drei Helme, da ein(e) Fahrer*in verletzungsbedingt länger ausfällt und noch nicht sicher ist, ob Fahhradfahren weiter möglich ist.
Daher reduziert sich die aktuelle Anforderung auf: A-B (meine Frau und ich), A-B-C (Gruppe), B-C und A-C.

Den Kopplungsmodus erreicht man durch Drücken der Mitteltaste für etwa 10 Sekunden.
Ich habe (nach vollständigem Reset der bereits bestehenden Zweierbeziehung in Helm A und B) in der folgenden Reihenfolge gekoppelt (in Kopplungsbereitschaft den Mittelknopf am jeweils erstgenannten Helm gedrückt):
A-C
C-B
A-B
Damit funktioniert das Verbinden, wie folgt:
A-B: Einfachklick an beiden Helmen
A-C: Zweifachklick an beiden Helmen (!)
C-B: Einfachklick an C
Oder: Groupconnect (Plus- und Minustaste drücken - ergibt eine grün leuchtende LED) an einem von *allen* Helmen!

A-B-C:
Einfachklick und Zweifachklick an A
Einfachklick an B, Zweifachklick an C
Einfachklick an B, Einfachklick an C
Oder: Groupconnect (Plus- und Minustaste drücken - ergibt eine grün leuchtende LED) an einem von allen Helmen!

Zum Groupconnect ist zu bemerken, dass es (uns) nicht gelungen ist, das halbwegs zuverlässig temporär auszuschalten.
Bei Vwerbindung über Mehrfachklicks (blaue LED) gelingt dies problemlos durch entsprechenden Ein- oder Zweifachklick…

Die größte „Überraschung (s.o.): Das System ist flexibler, als gedacht - Groupconnect funktioniert von allen Helmen aus und die Zweifachklicks ebenfalls von beiden Helmen aus. So erscheint der „Masterhelm“ nicht zwingend erforderlich.

Falls wir um den vierten Helm erweitern, ergänze ich hier. Ich gehe davon aus, dass ich mit den vier Helmen auch wieder einen Masterhelm (A) nutzen werde. Das heißt, dass ich (wie bei der Erweiterung von 2 auf 3 Helmen) alle Helme zurücksetze und mit leerer Konfiguration anfange.
Sonst kommt („Der letzte wird zuerst bedient“ ) - bei Helm A beim Einfachklick nicht B, sondern D …

Viel Spaß - wir haben ihn definitiv.
