Watch looks great and easy to use.
A great watch by Garmin. Took a while to set up but relatively easy. Very accurate when used for running and cycling yet to try it out in the pool. A few good widgets for it quite like the star finder. Only problem with it so far was the keeper on the strap broke within a week. Contacted Garmin and was sent a couple of replacements which arrived within a couple of days. A bit pricey at nearly £270 but very happy so far.
Comfy, accurate and efficient
I decided on this watch after a lot of previous research into the varying Garmin products. So far it has done everything correctly and accurately. I am very much enjoying using it and my marathon training to going smoothly thanks to the data collected
The watch is a fantastic
Whilst Apple Airpods do not feature on the list of compatible headphones, they do operate with Bluetooth so I would expect them to work with it.

I can confirm that you cannot pair this watch to a heart rate monitor.
This has the heart rate monitor feature so you can track your heart rate on this device.
I hope this helps :)
