It's low profile, but two piece (outboard battery that typically mounts on the back of the neck roll). Don't know if that makes a difference for you.
The basic operation is like the 10S, meaning that it's a single channel Bluetooth receiver. If you're riding solo, it probably won't make any difference for you. If you're ever riding with other people and want intercom and music/directions, be aware that the audio priorities will cause you to drop the intercom every time you get a signal from your other devices, which will require you to manually re-initiate intercom connection. If you want to maintain more than one connection simultaneously, you'll need to step up to at least the 20S.
In my personal experience, getting Sena devices to pair up with other brands of Bluetooth communicators can sometimes be frustrating. That may or may not be an issue for you, depending on how badly you want to talk to other people.
The "brick" look is kind of the way of the world outside of the 10R. The only other low-profile mainstream unit I'm aware of of the Cardo Packtalk Slim.
I've not been hugely impressed with Sena's customer service or update philosophy. They say "lifetime updates", but in Sena terms that seems to mean "until we come out with a newer unit that we want to sell more of". When Sena quits prioritizing your model, you're pretty much out in the cold. The 10R is still available, but in technological terms is quite old. I don't have any great confidence that Sena will be supporting it for much longer.
Knowing what I know now, if I were to purchase all over again I'd probably go with Cardo units. In your case and preference, that'd be the Packtalk Slim.
