A:AnswerNo you cannot with the smaller watch. My husband has the same one but larger. I was aware of this possibility when I got the smaller one. I called customer service to double check and the updates to make it possible have not been done for the smaller watch.
It does notify you when a call is coming in and you can talk to text message but you cannot make a call talking into the watch. The larger watch DOES do this.
A:AnswerThe zenwatch w1502Q does not have a speaker built into it. The W1501 model is the version with the built in speaker. I personally have the 1501, and purchased a 1502 for my wife and discovered the difference after we got it home. All other functions are pretty much the same. I am including the ASUS product website so you can see the direct comparison.
