Questions buyers ask
Does the Forerunner 165 support music streaming?
It can store up to 16 MB of MP3 files for offline playback; it does not stream directly.
Can I use the watch without a phone?
Basic tracking works standalone, but features like live location, incident alerts, and notifications require a paired smartphone.
Is the heart‑rate sensor accurate during high‑intensity workouts?
Garmin's wrist‑based sensor is generally reliable, though chest‑strap HR monitors remain marginally more precise for very intense intervals.
