It is the updated brush less version and comes with the 4.0AH battery. Anything new nowadays with the companies products seem to always have the 4.0

We are not sure weather we can get the v1.0 FOR you ,but if you purchased it , you can sent us emails to tell us to offer the V.1 0 ,normally what we have is the V4.0

I have 2 of these. I do believe they are 3.0. The sena warranty can't be beat. One of the clips that holds the unit to the clamp broke. I had a new one from sena in my hand in 5 days. Hope this helps.

Yes, but a cheap one. I upgraded and added a 2nd battery. Very fast & very happy!

The one I got was a slightly different model that is actually analog. The description on Andrea's webpage doesn't say whether the one you asked about is 2.0 or 3.0. I'm sorry I couldn't be of more help.

not sure what you mean, but by the model name you can deduce it's the 3rd iteration, so gen 3 if you like.

it is 3.0 but it comes with a separate USB cable to provide power if your using USB 2.0, so in that case you will need 2 USB ports. BTW USB 2.0 and USB 3.0 are the exact same connector, USB 3.0 just provides more power.

Mine came as a rev 4. The one it replaced was an original rev 3. Works fine with no issues that I have found.

I have the 7.0 and no. It doesn't keep a charge. I plug it in a socket and a "X" on the battery icon appeared.

It does use bluetooth 4.0. Not sure how long the battery life is, but I charged it fully when I first got it and haven't needed to charge it since in spite of using it nearly every day.

The version I got after buying is 3.8. Dunno why the picture is different. Maybe the seller ran out of 3.8 cause I believe I got one of the last ones.

Im not sure if it is 3.0 but it works great in my wife's Mercedes. VERY VERY Reliable!! It works great with iPhones, iPads and Droids.

The one I got in Dec 2013 is 1.0 :-(, but it was on sale so maybe they cleared out the old ones, not sure how much a difference it makes as the 1.0 one ROCKS!

The battery is replaceable. The information that came with it said it is Bluetooth 4.0--hope that helps.

I am wondering if the X4 has a 5600mAh battery or the 4400mAh. Anyone know?
