Compare Coros Pace 4 vs Garmin Forerunner 170 Music

Heart-rate accuracy was usually good for steady running, but reviewers repeatedly saw weaker results in intervals, cycling, gym work, or cadence-lock situations.

Heart-rate tracking is generally strong for running and mixed training, with several reviewers calling the older Elevate 4 sensor very good. Hard intervals and strength work can expose some lag, so a chest strap remains the cleaner choice for precision.

GPS accuracy drew the strongest agreement: most reviewers found tracks and distances excellent, with only occasional drift or margin-of-error complaints.

GPS performance earned unusually consistent praise despite the single-band hardware, with reviewers finding it close to pricier multi-band Garmins and accurate on city, coastal, and woodland routes. Multi-band remains preferable for the toughest dense-city or deep-trail conditions.

Core fitness tracking was viewed as accurate and useful overall, with some caveats around open-water swim and more difficult sensor scenarios.

Across running, swimming, gym work, elevation tracking, and race-style intervals, reviewers found the watch consistently accurate and useful for analyzing performance.

Sleep timing was often acceptable, but sleep-stage accuracy and the watch’s judgment of poor sleep were questioned by several reviewers.

Sleep tracking has improved enough to broadly match an Oura Ring on sleep duration, bedtime, and key stages on most nights, though Garmin’s history here was acknowledged as weaker.

Recovery and training-load insights were useful for interpreting fitness, although one reviewer criticized Coros’s weekly training-load reset.

Training Readiness, Training Status, load, and recovery guidance are among the watch’s biggest strengths, helping runners structure training and avoid overdoing it. One reviewer cautioned that beginners can become too dependent on recovery scores instead of listening to their bodies.

Coaching and training features were useful and unusually complete for the price, though Garmin-style guidance and some plan options were still stronger elsewhere.

Garmin Coach and Quick Workouts are standout strengths, offering adaptive plans, fast structured sessions, and useful guidance for everyone from first-race runners to experienced athletes. Suggested Quick Workouts can occasionally be tougher than expected.

Reviewers praised the broad workout profile selection and multisport coverage, even while noting that some adventure-focused modes stay on higher-end models.

The jump to more than 80 sport profiles makes the watch far more versatile than older entry Forerunners, covering running, gym, team, winter, and water activities. The lack of native HYROX and multisport/triathlon modes still leaves gaps for some athletes.

Wellness insights such as HRV, readiness-style guidance, and training trends were helpful for many users, but not every wellness check felt actionable.

Garmin’s broader wellness package is viewed positively, especially the comprehensive health data and useful evening reports that recap the day and help frame the next one.

Battery life was a standout across nearly every review, especially given the small case and AMOLED screen.

Battery life is adequate rather than class-leading. Depending on display settings and training load, reviewers saw roughly three-and-a-half to six days in heavier real-world use; most runners found that workable, but it trails some cheaper or older alternatives.

Charging convenience was mixed: the small USB-C adapter and keychain were handy, but needing a separate cable added friction.

Charging is a clear annoyance: the proprietary Garmin cable can be finicky to keep seated and feels dated compared with USB-C.

Comfort was one of the clearest strengths, with reviewers repeatedly praising the light, small watch for all-day and overnight wear.

The light, slim case is exceptionally easy to wear for workouts, sleep, and daily use, especially on smaller wrists. The main comfort caveat is skin irritation reported from the strap or back casing by a couple of reviewers.

Materials quality was mixed: the plastic helped weight and comfort, but several reviewers called it budget or not lavish.

Materials are a weak spot compared with premium Garmins: the polymer construction feels basic, and one report flagged possible skin irritation from the plastic back during prolonged wear.

Water resistance was adequate for wet use and casual swimming, but reviewers did not treat it as a rugged diving-level feature.

The watch handled swimming well in testing and was considered safe and dependable for both pool use and showering.

Fit was positive in the available evidence, with the 43 mm case sitting well on the wrist.

The compact case fits smaller wrists well while still being judged suitable for a broad range of wrist sizes, with little catching or digging during wear.

Band quality was mixed: silicone was practical and straps were comfortable, while nylon drew complaints for holding sweat or moisture.

The silicone band feels soft and stretchy, but one reviewer developed a rash from it, making long-term skin comfort a real point of variability.

Build quality was acceptable and functional, but the lightweight plastic design kept it from feeling premium.

The build is functional and familiar rather than premium, described as standard Garmin fare with a lightweight plastic character.

Style and design were well received, with reviewers calling the watch sleek, clean, attractive, and helped by the AMOLED display.

The watch keeps Garmin’s sporty look but earns praise for fun color choices, coordinated bands, and a polished appearance that still feels light on the wrist.

Display quality was a major upgrade, with reviewers repeatedly praising the sharp, colorful AMOLED panel.

The AMOLED screen is one of the watch’s most praised features: colorful, sharp enough for dense run data, and easy to read. It is not as fluid or premium as flagship smartwatch panels, but reviewers still rate it highly.

Brightness was usually strong outdoors and in daily use, though one reviewer found the default mode conservative.

Reviewers consistently found the AMOLED display bright and vivid enough for normal use, including direct sunlight, even though Garmin’s pricier watches can get brighter.

Outdoor visibility was consistently good, with reviewers reporting clear readability in sunlight and varied conditions.

Outdoor readability is excellent, with multiple reviewers saying pace and data remain easy to see in bright sunshine and normal running conditions.

Reliability was positive in the available evidence, with the watch described as a solid sports-watch performer overall.

In demanding race preparation and event use, the watch did its job consistently, delivering dependable data and controls without getting in the way.

Value for money was the strongest consensus point, with every review framing the Pace 4 as unusually competitive for its price.

Value depends heavily on what you need. The 170 Music packs premium training tools, accurate tracking, payments, and phone-free audio at a lower tier than Garmin flagships, but several reviewers think the cheaper 70, discounted 165/265, or Coros Pace 4 can be better buys.

Smartwatch features were consistently described as basic, making the Pace 4 more of a training tool than a full smartwatch.

The 170 Music goes beyond pure run tracking with payments, apps, notifications, music, and a more complete smartwatch interface. Reviewers still see it as a sports watch first rather than a true phone-replacement smartwatch.

Onboard music support was limited because it depends on owned audio files and lacks Spotify, Apple Music, or other streaming-service integration.

Offline music is one of the Music model’s clearest benefits, letting runners leave the phone behind and load playlists from supported services. The feature is easy to live with, but the price premium and Apple Music gap weaken the value for some users.

Contactless payments were missing, which reviewers treated as part of the broader smartwatch-feature gap.

Garmin Pay is useful for phone-free runs and everyday purchases, but reviewers disagree on whether it justifies the price premium over the cheaper Forerunner 70.

Music controls were mixed: some reviewers praised phone media controls, while others noted absent or not-yet-available controls during testing.

The touchscreen makes on-watch music controls notably easier to use and helps the device feel more like a regular smartwatch.

The Coros ecosystem scored well because training analysis is broadly shared across the range and app/training-lab access was praised as free.

Connect IQ adds some smartwatch extensibility, but one reviewer found its useful app selection much thinner than Apple’s or Google’s stores.

Button controls were useful for shortcuts and navigation, but reviewers disliked the digital dial during runs and the limited action-button behavior outside activities.

Garmin’s five-button layout is a major practical strength for runners because it remains easy to operate with sweaty hands, gloves, or a bouncing stride. One reviewer noted a small ambiguity around the start button.

Third-party app support was a clear limitation, with reviewers flagging the lack of app expansion versus smarter watches.

Streaming support is a mixed point: Spotify, Amazon Music, Deezer and some other services work well, but Apple Music’s absence is repeatedly called out as a meaningful limitation. Spotify offline use also requires Premium.

Touch responsiveness was mostly good, but accidental touchscreen or dial input was a recurring annoyance.

The touchscreen is repeatedly described as snappy and responsive without becoming overly sensitive, making swipes and taps reliable in daily use.

Software smoothness was a strength, with reviewers describing the watch as snappy and lag-free, though less glossy than Garmin in places.

The updated software is praised for faster performance and smoother navigation than Garmin’s older budget-watch experience.

Customization was solid for sports fields, structured workouts, and button functions, with some limitations in watch-face flexibility.

Watch faces, widgets, and data screens can be customized extensively, letting runners prioritize the information they actually want to see.

Menu navigation was simple and practical, but one reviewer felt the interface lacked smartwatch polish.

Five-button navigation is generally easy and dependable, especially while running, and the newer software feels smoother. The main drawback is that some capabilities remain buried in settings.

Mapping and navigation were the most common tradeoff: breadcrumb navigation worked for many runs, but the lack of offline maps pushed some reviewers toward Pace Pro or higher-end watches.

Breadcrumb course guidance is useful for everyday routes, but the lack of full offline maps is one of the most repeated omissions. It is fine for familiar roads and basic course following, less convincing for wilderness, ultras, or map-heavy trail use.

Pairing reliability was positive in the available evidence, with the reviewer reporting no issue connecting wireless headphones.

Syncing and connection behavior impressed in testing, with near-instant GPS lock and quick, easy Strava synchronization.

The user interface was generally considered easy, simple, and understandable, even if it remains more basic than some rivals.

The on-watch interface is widely considered simple, polished, and easy to use through either touch or buttons. Small quirks remain, including buried settings and an occasionally ambiguous start-button interaction.

The companion app was praised for ease of use, improved polish, and transcription support, though voice content stayed inside the Coros ecosystem.

Garmin Connect is powerful for training analysis and can make certain tasks easier, but one reviewer felt the app still badly needs a redesign. Its depth is useful, though not always elegant.

Operating system experience was praised for strong performance on the updated processor.

The latest Garmin software feels more polished and cohesive, bringing sports and smartwatch functions together with a sleeker presentation. Reviewers also value its position for receiving newer features.

One reviewer found the run alerts comically loud and disliked having no separate volume adjustment beyond disabling sound and vibration.

Bluetooth connectivity was positive in the limited evidence, with wireless headphones connecting without issue.

Notifications were a weak point, with reviewers calling them basic, tiny, or nearly useless while running.

Reviewers liked the workout voice notes when transcription worked well, but several treated the feature as niche or less convenient than it could be.

Watch faces were attractive by default, but reviewers wanted more customization and richer watch-face options.

Pulse Ox is welcomed as part of the expanded health package, bringing a feature that previously sat above this entry-to-midrange tier.

Health tracking was generally useful for big-picture trends, though reviewers found some accuracy limits when heart-rate and sleep data became more demanding.

Step counts were reported as aligning well with Garmin and Apple watches in testing.

Stress tracking was treated as accurate enough for a general picture when combined with sleep and heart-rate data.

Garmin Connect worked almost identically on iPhone and Android in testing, making the core experience effectively platform-neutral.

The display flashlight was useful in a pinch, but several reviewers said it could not match a dedicated LED flashlight.

LiveTrack is a useful safety extra for solo activities, giving contacts a way to follow the wearer’s location when a phone connection is available.

Durability raised concerns because mineral glass and the low bezel were seen as less protective than tougher premium materials.

Size options were a limitation because reviewers wanted more than one case size and found the single smaller size unsuitable for some users.

Wrist-based running power is welcomed as a surprisingly advanced training tool at this price, giving runners another way to manage effort and work on form.
