Nice units. As with a lot of electronic items, they do so much more than I will probably use. Quite a learning curve, took a couple weeks to figure out the intercom connection consistently. FM radio came on one day, not a clue how that happened. Had to be the ID10T error, LOL. All in all, love it.
I'm very happy with my Sena purchase. It has changed the riding experience like you wouldn't believe. It's amazing having the ability to make and receive calls while riding my motorcycle. I also stream music while riding. Can't wait to use the rider to rider intercom. I highly recommend the sena SMH10.
We replaced our two piece wired headsets with these. They are easy to use and have good sound quality. Not having wires is a big plus. There's a short time delay in communications at times. It's not problematic though. The microphone covers do a great job keeping wind noise at a minimum. Range is great and turning them on and off is simple. Downloading the current firmware update was a bit of a challenge. The instructions aren't that clear. The only downside is the way they sit on your ears. The headband is made to go around the back of your head, not over the top. The unit is just a tad too heavy to sit properly on your ears, so they ride a bit low and feel a tad awkward. It would work better if you had an option to have the headband sit over your head or behind your head.
I bought this because the design of the Nolan N90 helmet causes the plug in to be bent on your shoulder of your jacket. I paid over $50.00 with shipping and after plugging it in you can not hardly hear the stereo. I then plug in the original cord and it worked fine. The quality control is terrible on this product. No wonder Nolan changed the style of plug on the new helmets.
