I have Sena, Uclear, and Nolan B4.
Sena SMH10- great all around. They have a great person to person sound. Good range. Great battery.
These will work with other brands but I've never done it.
The only the I didn't really care for was the boom mic. In some 3/4 and full helmets the mic will contact your face.
It mounts easily on most helmets but sometimes it's can be a challenge.
The button operations in these are really easy, even in gloves.
Uclear HBC 200- good all around. Good person to person sound. Good range. Great battery.
These are really nice as they install super easy and have many different speaker options for all helmets. You simply stuck the mount in the helmet and slide the Uclear pod onto it. It makes it for most any helmet extremely easy.
They do not work with other brands, not to my knowledge.
These have no boom mic and instead the mic is in the speakers or a thin wire you run in the headliner of the helmet. They work incredibly well. Just like with my Sena people usually have no clue I'm on a bike.
The button on here are hard to use on the helmet, especially in gloves. I added a handlebar remote which was much easier to use and I feel is well worth the money.
B4- this goes in Nolan helmets. It is specific to them and if you don't have one there is no need of checking it out.
This one does pair with other brands but I've never done it.
The buttons are ready to use and it sounds good with an ok battery.
Between all three I have enjoyed the Uclear most. To answer the phone you simply say "pick up" or "hello."
Excellent review and comparison! I have the UClear, the Scala Rider and FreeComm T-Rex. I use the UClear when I ride with my brother. The range is about half a mile. You must speak normally when you use this system, if you raise your voice, it sounds muddled on the other side. It can be updated on line. When ours were at the booth at Laughlin River Run, they were better. There was an ear bud option that I liked but I think it has benn discontinued.
The Scala Riders are 5 years old. I use them when my wife rides on the back.
They work well and once paired will sync automatically. They have a boom mic. They work well but wind noise seems louder with them. The T-Rex is designed to work in groups up to 8. I use this when I ride with my touring buddies. The range is about 1/2 mile and works great in the mountains even when your partner is a few curves ahead. Wind noise is minimal, voices are clear. I can make phone calls while riding with this one. This is my favorite! It is an off brand I found on Amazon and only cost me $145 for my headset. It looks like a Sena but it won't pair with any other brand. My buddie's headset would not pair with us and his cell phone. He seemed to have a relatively easy time getting it replaced.
I can't get my brother or my wife to switch to the T-Rex because they are happy with what they have. My point is most brands will do what you want reasonably. My challenge is none will allow you to toggle between group and just talking to your passenger. (probably why my wife won't switch. She doesn't want everyone to hear when she burps.)
