Looks like I am one of the first reviewers of the SENA Savage Helmet. My primary purpose of this purchase was to switch from a half helmet to offer some protection to my rapidly deteriorating hearing. I used the SENA sizing chart and determined I needed a medium but I dislike tight fitting anything, so I ordered a large. Its still lightly more tight than I would prefer, but that's just me. The helmet is well made and seems high quality throughout. Its lighter than it looks (a plus) On to the features: The two control operating system is easy to use even with gloves on. It takes a little while to get used to the "timing" of the controls (push/hold for 1/2/5 seconds starts different functions) but once I got it down I found the functions easy to control. Radio: picks up stations really well, and the scan function is cool. I do not like the loud "beeps" and voice prompt when a station is first locked in. It identifies the station with three beeps and a voice which are little too loud and cannot be controlled by the volume. I would prefer that the tones/voice be in alignment with the overall volume. Radio sound quality is average. With bluetooth on and my phone in use, sound quality is better and the SENA app lets you select tone controls and built in settings. Sound quality is much better with bluetooth. But at 75 MPH neither radio nor bluetooth can overcome the freeway noise. One would probably go deaf from the music itself being too loud. I've tried other helmets and on-bike sound sound systems, and I haven't found any that were perfect at highway speeds, so the Savage isn't any less quality than what the overall market offers. Sound volume/quality on the freeway is just an inherent problem that riders will have to live with. Intercom/phone: It took a little work but I was finally able to sync with other riders. Sound was clear and loud enough, except again, at highway speeds. SENA claims a 1 mile range and I couldn't test that due to the limitations of the other synced helmets, but a half mile range revealed good sound with some static (that may be due to the other helmets). the microphone is built into the visor area of the helmet and picked up my voice well, but also picks up other noise. The noise reduction feature does greatly improve the quality. I was able to answer calls and sound quality was good (and once more, except at 75+ mph). I have not fully tested all the features on this helmet but think most users will stay with the basic functions anyway. The SENA app is easy to use and offers many controls and features that enhance the performance of the helmet and is a "must have" to get the full benefit of the Savage. Overall I give the Savage an 8. The annoying loud beeps/voice prompt should be synced with the volume control. I'm not sure any helmet is going to be able to overcome freeway/high speed noise. If you want to feel like you are in a concert hall, you will probably need to cage it. Still, the helmet is well made, operated well, and I was pleased with its performance. At $400 this is not a cheap price and may be slightly over priced in my opinion, but I don't feel like I was gouged and its far cheaper than a good set of hearing aids. The Savage performs as well or better than anything else I tried (ear buds etc) and I think I'm going to really enjoy it.
