HRM Pro + and more

Hi,
I don't trust heart rate measurements from sports bands/watches. That's why I bought HRM Pro +, previously I had the vivosmart 5, yes, I know they don't work together and the results provided in the application are only those from vivosmart (unless I turn on the activity, take off the band and put it on after the exercises), but then the results are not at all adequate.

I exercise indoors on an elliptical trainer, pilates, circuit classes and outdoor, I ride a bike every day.

I would like to combine these disciplines, but so that when I put on HRM Pro+, it would be a heart rate monitor (cardio exercises).

I don't like large and heavy watches (to tell the truth, the sports band sometimes bothers me) and if it had the ability to pair headphones and upload dozens of MP3s and play them, it would be perfect.

Recommend one of the watches that will meet my expectations Slight smile
