Sena Impulse DOT Flip Up Modular Bluetooth Helmet w/Sound by Harman Kardon Dual Visor Helmet with Integrated Mesh Intercom System / MP3 / Voice Dial (Gloss White, Small)

I am a little disappointed, I expected better. first let talk about the pro and conPRO:- Sound is AMAZING- Built in FM radio- Good looking Helmet with safety light (on or blinking) at the back of the helmet- Modular but feel solidCON:- Size chart is off. Err on the small side. Be aware- Charging magnetized plug is IDIOTIC. Does not stay in place. Why not use a micro USB ????????- WORSE THAN ANYTHING, the app (at least for Google, I don't have an iPhone) is WORTHLESS. Even when the helmet is pair with your phone, the app shows that the helmet is not and makes difficult if not impossible to access the setting.- The light in the back does NOT work. Is it because of the app (the only way to turn the light on and off or just malfunction from the start. I do not know. But one main feature of this helmet isn't workingI reorder a bigger size and hope that the light is working, if not it's a bummer but I will keep it just because the sound is just incredible even at high speedReturned the medium size and got a large. Fits much better. Also the light is now working and the apps seems to connect better. So updated the review to a 5 stars. Very quiet and sound is really fantastic

Helmet is perfect. Sound very good. Battery life horrible. In 8 months my Sena unit's battery drains in just 30 minutes without music just standing by for calls. I will see if there is room for a Cardo unit

Was on the fence about spending this kind of money, but I did it and I am not disappointed at all. This helmet is amazing. The quality of the helmet and the Bluetooth which is integrated into the helmet is crystal clear and works so great. The helmet does have the slide down tinted shield inside, but I purchased a tinted shield for those extra long days of riding. This helmet is 100%quality.I will be purchasing another one for a family member. Take not though that this does run small.so if you normally take say a large, you will need to order the next size up.and remember you have to break a helmet in.so if it’s “just pretty snug” it will break in and you do not want a helmet that is too big or loose.this only comes in black and white at the time I am writing this review, hopefully they’ll come out with more coo later.

I have an ILM $80 helmet which I enjoy wearing. But I wanted a bit higher end helmet with bluetooth. The ILM 902/935 got shotty reviews but I picked one up anyway. The large helmet fix WAY tight, the sound was sub par and there was a constant electronic crackle when connected to my iPhone. I returned it now having the Sena Impulse in my hands. I took a gamble and ordered an x-large and the size feels very tight. I have to open the front face of the helmet to get my head in. Once I got my head in, I found the sound and volume levels very nice/loud. Calls, music, Siri and status' come in clear <60 mph. With the louder volume, music "can" be heard" but Siri can get confused with wind noise. But I have had some successes abate with multiple tries for the same TN or GPS request.Most helmet have a dial to control the bluetooth. This one has 4 buttons which I imagine feels like Im learning brail every time I make a change. The extra thick ((battery warming) gloves Im sure dont help. I think from extra usage I'll eventually learn Sena brail (which I am not a fan of). Also the manual claims there is a charging dongle and a usb_c cable (with the same magnetic connector as the dongle) that is suppose to be supplied. Im talking to support about the missing cable now so we'll see.... I have usb-c cables but if I lose the dongle Im hosed. I'm deciding to keep the Sena ($599) which will pay off with longer ride but will wear my ILM (non bluetooth helmet) for shorter ones as I can pop my head into the (Large size) hole with out opening the chin guard and its a cool looking red. Sena only comes in black or white :(So here I make a weird comment. Am I keeping it? Yes. Would I buy it again? Maybe as I'd look at other options first. Would I recommend it? Yeah, if your head was smaller, got your usb-c cable and want to learn Sena brail! Again Sena has the loudest volume option that I have experience so far and that tipped the scales for me.Update 30 days later: After 30 days of usage I would love to return the helmet. With ILM I wear a Large but with a XLarge Sena the helmet gives me a headache due to the tightness. I cannot put on the helmet without opening the front shell and spreading the sides.I did call support about the missing charging cable and never got results so I need to be extra careful with my proprietary charging dongle as without would make the blue tooth useless without charging. Again the blue tooth sound is the loudest I've ever experience but would I recommend or buy this helmet again? Probably not. Due to the tightness, my daily helmet goes to my $80 ILM.

The helmet is good quality, fit is slightly tight but is brand new like my momentum it was tight to start very comfy now 3 years later. Device connected very fast to all other device I have for use with this helmet and had to replace my Garmin Zumu XT and once that was setup it connected readily to it.

Only problem is the charger is not USB c. If I had known,I would have skipped this one. Sena helmet sizes are seemingly based on pelican skulls. Order 2 sizes up from a bell or shoei or whatever...... Speaker performance is decent. The app is trash. My helmet did not come with the needed wifi cable for firmware updates..... Idk if it would make any difference though. If it fit like all the other CL helmets I have had, I would have gave 4 stars for the speaker quality.
