Head-to-head

Forerunner 165 vs 170 Music: Will the phone come anyway?

The short answer

Choose 170 Music if downloaded watch audio lets you leave the phone behind. Choose the non-Music 165 when the phone already comes for calls and audio. Neither replaces the phone for ordinary communication. The 170 Music also adds current training features, but its all-systems-with-music ceiling is 6.5 hours. Check the whole routine before buying it as a long-day audio solution.

Before you choose

The reasoning and the trade-offs

The school-call requirement can make watch music an optional extra

A runner may want to leave the phone at home for music and still be available to a school or relative. Neither selected watch solves the second requirement independently. If that means the phone stays in a belt anyway, 165 can control its audio while recording the run. The 170 Music is more valuable on sessions when the phone can genuinely stay behind, or when phone audio is deliberately being avoided. Separate those two weekly routines before paying for a capability that may not remove anything from the kit.

What this is based on

Phone-free listening plus ordinary family calls. The conclusion depends on the buyer retaining the phone for contact, not on an assumed universal need.

About this comparison

Compare the non-Music Forerunner 165 with 170 Music for phone-free playlists, family calls and charging before long runs. Exact versions matter.

These are compact Garmin running watches aimed at buyers below the flagship tier. Comparing the selected non-Music 165 with 170 Music resolves whether offline audio and current training additions justify moving up, rather than quietly borrowing the separate 165 Music SKU.

What matters in practice

The differences that matter

The school-call requirement can make watch music an optional extra

A runner may want to leave the phone at home for music and still be available to a school or relative. Neither selected watch solves the second requirement independently. If that means the phone stays in a belt anyway, 165 can control its audio while recording the run. The 170 Music is more valuable on sessions when the phone can genuinely stay behind, or when phone audio is deliberately being avoided. Separate those two weekly routines before paying for a capability that may not remove anything from the kit.

How we reached this conclusion

Phone-free listening plus ordinary family calls. The conclusion depends on the buyer retaining the phone for contact, not on an assumed universal need.

A rushed morning moves the work to the previous evening

With 170 Music, a downloaded playlist can be ready before a run, but the setup is not finished forever. Spotify needs Premium and periodic Wi-Fi renewal. Garmin lists more than 15 days without watch synchronization as one reason downloads can expire or disappear. Someone who runs only occasionally should check the watch before the morning they finally have time. The 165 uses the phone’s audio setup instead, which may already be maintained through daily listening. Neither arrangement is automatically less work. The better one is the library and charging routine you will actually maintain.

How we reached this conclusion

Infrequent runs plus short departure windows crossed with subscription renewal. No assumed sync duration or guaranteed failure exactly on day 16.

A day-long charity outing is different from an hour before work

The 170 Music lists 6.5 hours with all-systems GPS and music together. A planned seven-hour walk or run is beyond that published ceiling before allowing for navigation, display use or an aging battery. The 165 cannot take over the same phone-free audio job because it lacks storage. If the phone will supply music, both watches move into a different use case and their watch-only recording figures become more relevant. Do not choose between them by comparing 17 hours on 165 with 6.5 on 170 as if both figures included playback.

How we reached this conclusion

Seven-hour illustrative event and exact mode matching. Rejects an invalid cross-mode battery comparison.

Recommendation switch

The decision flips if...

The phone stays in the kit for ordinary calls

Choose Garmin Forerunner 165. 165 can cover recording and control the phone’s audio.

Music is the only reason you carry the phone

Choose Garmin Forerunner 170 Music. 170 Music can remove that reason after downloads are prepared.

What matters in practice

Before you choose

You want fewer things in your pockets, but family contact may mean the phone has to come regardless of where the music plays.

Check these before buying

  • Confirm non-Music 165 versus 165 Music.
  • Check the music service and renewal routine.
  • Leave battery reserve beyond the expected outing.

What this comparison cannot tell you
