Main trade-off
Garmin Forerunner 170 Music
Subscription access and renewal remain part of the routine. Its all-systems-with-music ceiling is 6.5 hours.
Head-to-head
Choose 170 Music when compatible subscription downloads are the easiest way to take your music running. Choose PACE 4 when owned MP3 files and computer transfer suit you, or its released mapping and higher published recording ceilings matter. PACE 4 is 40 g with the selected silicone band, versus 41 g for 170 Music. Neither music workflow provides ordinary phone-free calls. Garmin Spotify use needs Premium and periodic watch Wi-Fi renewal.
Before you choose
If all your music comes from Spotify and the household uses phones and tablets rather than a Mac or PC, PACE 4’s offline music requires more than a watch purchase. COROS documents computer transfer of MP3 files, which is not the same as copying protected subscription downloads. The 170 Music can fit the subscription routine with a compatible service, but Spotify needs Premium and periodic Wi-Fi renewal on the watch. Someone who already owns MP3 files and a computer has the opposite starting point and may find PACE straightforward. Count the missing inputs before comparing music as a shared tick box.
What this is based on
Streaming-only habits plus no computer crossed with exact file, device and subscription requirements. No unsupported transfer workaround or claim that all providers behave alike.

Main trade-off
A streaming subscription is not a transferable MP3 library. Local music needs a Mac or PC and suitable files.
Forerunner 170 Music vs PACE 4 for Spotify, travel maps and long runs. Check the missing device or subscription before choosing a phone-free music watch.
These small AMOLED running watches have almost the same supplied weight and target overlapping buyers. Real cross-shopping exists. The music ecosystem, current mapping and combined battery mode create practical differences beyond a feature count.
Winner by situation
Garmin still needs Premium and renewal. COROS does not accept that streaming-download workflow.
170’s stated ceiling is below the plan. PACE still needs reserve.
PACE 4 now has released mapping, with downloads required.
Local music and mapping do not provide independent phone service on either selected model.

An eight-hour outing with all-systems recording and watch music is above 170 Music’s 6.5-hour ceiling. PACE 4 lists 14 hours in its High all-systems mode with music, making it a more plausible starting point if the local-file workflow suits you. These are different manufacturers’ ceilings, not evidence that PACE will last a measured number of hours longer. Display settings, temperature, navigation and battery age still need margin. If a phone already comes along for family calls, playing music from that phone changes the watch mode and may remove this specific reason to switch brands.
Eight-hour illustrative outing plus local playback plus retained family contact. Official combined-mode limits used as an exclusion test, not a matched runtime prediction.
PACE 4 now has released mapping, which can help when an unfamiliar running route changes. That benefit depends on installing the update and downloading the right region before leaving. Its 4 GB nominal storage is also shared with other content, so a large MP3 library can compete with the maps you want ready. The 170 Music offers a different familiar Garmin course and playlist routine, but subscription downloads can need renewal after a quiet period. For either watch, test the route and music the evening before travel. A mapped point of interest does not establish opening hours, path access or a safe shortcut.
Travel plus local audio crossed with mapping update, shared storage and subscription renewal. No automatic routing or accessible-path promise.

Meaningful differences
| What changes | Garmin Forerunner 170 Music | COROS PACE 4 | Why it matters |
|---|---|---|---|
| Music you can load | Compatible provider downloads, including Spotify with Premium and renewal. | MP3 files transferred from a computer, no streaming-service downloads. | The existing library and available devices can decide before battery does. |
| Current map context | Garmin running-watch course workflow. | Released mapping added September 26, 2026. | Do not use the old PACE 4 no-map comparison as current advice. |
| All systems with music | Up to 6.5 hours. | Up to 14 hours in High mode. | Different manufacturer test conditions apply, but an eight-hour plan is above Garmin’s cited ceiling. |
| Selected supplied package | 41 g, 42.6 mm, 126–203 mm band. | 40 g, 43.4 mm, 130–215 mm band. | The weights are close. Band endpoints and the actual case fit can be more useful distinctions. |

What matters in practice
You want to leave the phone at home for music, but the watch with the longer battery may not accept the library you use every day.
