For most people, it's probably "good enough," but accuracy matters for athletes or anyone with serious heart conditions, and there's always room to improve.I use my AirPods Pro for all workout-related stuff. I bought some inexpensive plastic hooks that the AirPods sit in and have never had any issues with them falling out. Apart from being a very sweaty person and worrying that this will eventually cause issues with my AirPods, are there any significant reasons to consider buying these?
I also run with an Apple Watch Ultra so the HR feature would be no better than on the watch right?
ECG is the gold standard for heart rate tracking, with chest straps being the next best. But since wearing an ECG all day isn't practical and most people hate chest straps, the goal is to find a better alternative.
Wrist-based heart rate tracking is notoriously unreliable. Things like skin tone, tattoos, placement, fit, movement, and body fat all affect accuracy. Ear-based tracking isn't perfect, but it avoids many wrist-related issues—assuming you can get the earbuds to fit right.
