How is the noise reduction for the person you're talking to? Do you have to repeat yourself a lot?
I'm out of town at the moment, but when I get back I'll take it out and measure the speaker. As for the charge, it has lasted a few 5-6 hour rides without a charge. the unit just slides off the mount if you don't want to use it. it does not leave any permanent marks and you could move it from helmet to helmet. When I don't use the bluetooth (sometimes just don't want to be bothered on a ride), I just don't turn it on and you can't tell it's there.Michael Moore said:Yeah, I've got an X-11 also and ordered some speakers from HelmetAudio, but even they were too large and pressed against my ears.
Is there any chance you could measure the depth of the ear speaker and post it? I'd hate to shell out for one just to find I couldn't use it or would have to buy a new helmet.
Also, how long does the charge last? And do you ever take it off the helmet for sport riding, or is it pretty much a permanent install?
