I like to review products objectively and accurately. So, to that end, I submit this for your approval. If TLDR skip to the end.Comfort and fit: The helmet is true to size. Like other reviews, my ears folded a little bit when I put it on sometimes, but that is a non issue depending on ear size, how the helmet is donned, and break-in of the helmet padding. The chin strap is not invasive and fits comfortably under my chin and not too far back as to be uncomfortable or interfere with swallowing or talking. Weight is acceptable and comparable to the standard full face on the market. The padding is adequate and seems to be durable. Some of the interior foam is showing on the inside above the speakers, but that is only an aesthetic issue. The helmet holds firm to the head when strapped properly with minimal head shake.Protection and safety: As far as protection and safety is concerned, I am satisfied that the helmet is DOT certified. From a safety standpoint, wind noise is higher than my previous helmet. When I think about the wind noise it can be a little overwhelming, but overall not too bad. There will be wind noise. You're on a motorcycle. The visor is adequate and seals to the front of the helmet well. Clear child conveys which is acceptable due to the internal sun visor.Features: The sun visor operation is smooth and easy to operate. It locks in both the up and down positions. When locked in the down position the visor doesn't seem to be held entirely firm in place. In other words, operate the visor using the helmet switch only. Potential for breakage may be high if operated via the visor itself. However, shouldn't be an issue as there is no reason to operate it manually. The sun visor could stand to be a little darker, but it is adequate for the application. With direct sun, I had to squint a little bit. Overhead sun is not a problem. The main visor is a little slack in the "vented" position. It will snap close at road speed. (I mentioned this because I know a lot of riders like to "vent" the main visor to prevent or remove fogging.) This issue is partially alleviated during daylight by the ability to use the sun (internal) visor and leave the main visor up. Chin strap is standard and easy to operate. The vents are present, and well designed aesthetically, but the operation of the vents seems like an afterthought. Ventilation is not very good and can only be felt at higher speeds (>60mph). The graphics on the helmet are EXTREMELY subdued compared to the photo. Don't expect to be able to readily see the flag graphic. It was one of the reasons I bought the flag and not the plain matte. My suggestion is to save the additional money and purchase the plain matte or high gloss black.Design: Well designed and good looking helmet. This, of course, is subjective. However, I do not believe that it will make your head look big or floppy. The sharp angles are conducive to design and flow well across the helmet. Bluetooth knob in a good spot. Could stand to be an inch more to the front (as well as the sun visor switch). Be careful with the knob. It seems that it could break easy if you are not careful under gloved hand. It feels loose in the setting. Operation should be limited to rotating the knob and depressing the centerBluetooth: The moment you've been waiting for (of probably skipped to as I did in the reviews I read). The speakers are adequate. At max volume there is a little distortion while listening to music. The max volume is loud enough for even a loud bike (95 HD Sportster Custom with straight pipes...my bike is pretty dang loud). Low tones lack a little bit, but having music at all trumps most of the quality issues. There are no directions for operation of the Bluetooth. You are left to figure it out. Read the end to see what I found out. There is also some "skipping" or "dropping" off of music playback. It USUALLY goes away after about 20 seconds or so if it happens. I have not experienced any static, yet. The helmet is designed with the speakers in mind, so there is no ear interference (or very minimal). The microphone...horrible. Phone calls can be heard well, but the person on the other end can not hear when rolling; even at low speeds. There is droning and interference. I was told like I "sound like a robot" and "talking through a tube" and "talking in a tunnel" when I was going faster than about 15MPH. The problem seems to be with wind interference around the lower mouth area of the helmet. Some of the problem was partially solved when I blocked the entire lower portion of the helmet (dangerous while riding, but helped me diagnose the issue). Changing volume, tone, and rate of speech didn't help at all. The person on the other end said they could hear the road noise and my bike just fine...Overall: Good helmet for the cost. I would recommend this to anyone. If you are looking for high quality then spend the money. This is a great "entry level" Bluetooth helmet that any owner would be happy to own. The microphone need a lot of work and the speakers are adequate. The helmet is comfortable and the visors are excellent. This would be a good buy if you are looking to save some money but still have good protection for your dome piece. Four stars because of the microphone, apparent quality of Bluetooth components, overall quality, cost for product, features, and fit. It's a good product and I would purchase again if need be.MUST READ THIS!!!!!!Here is what I found out about basic operation of the BT with iOS:Music: pairing is easy. Hold down the button until the lights alternate to get it into pairing mode. Double press to play/pause music playback. Rotate and release clockwise to increase VOL (counterclockwise to decrease). Rotate and hold clockwise approx. 3 seconds or (until the beep) for NEXT TRACK (counterclockwise for PREVIOUS TRACK {within first 3 seconds of track}. Press once to answer/hang up calls. Keep your phone screen-up in you pocket so you can activate Siri (for voice dial/command) as needed. I have not used navigation, but I imagine the voice turn-by-tun is
