What is the Reddit Community Saying?

Suunto Smart Heart Rate Belt: What Redditors Are Saying

When evaluating any sports tech device, the internet—and particularly Reddit—proves to be a goldmine of user experiences, troubleshooting discussions, and comparisons with rival products. The Suunto Smart Heart Rate Belt, designed for accurate HR readings during training, has garnered a mix of praise and criticism from athletes, casual users, and tech enthusiasts alike.

Accuracy: "As Good As a Chest Strap Gets"

One common theme across Reddit discussions is that chest heart rate monitors (HRMs) tend to offer superior accuracy over wrist-based alternatives. This is where Suunto's HRM shines, with many users praising its consistency and reliability in heart rate tracking—a characteristic crucial for endurance training, HIIT workouts, and running.

A user from r/running shared:

“I ditched my wrist-based HR after getting unreliable readings during fast intervals. Switched to the Suunto Smart Belt and now my heart rate readings actually make sense. Definitely a game-changer for structured training.” 

In comparison, some runners have noted that wrist-based monitors (such as those found in Garmin or Apple Watches) often struggle with quick HR changes or extreme environmental conditions (e.g., cold weather impacting blood circulation). A discussion in r/trailrunning highlighted how Suunto's chest strap maintains accuracy even during rapid HR fluctuations, something wrist monitors frequently fail at.

However, not everyone found this to be the case—some users reported that accuracy can be influenced by factors such as proper strap placement, connection quality, and contact with the skin.

Connectivity: "Solid With Suunto, But Limited Elsewhere"

One of the more mixed aspects of the Suunto Smart Heart Rate Belt, according to Redditors, is its connectivity performance. The HRM transmits data via Bluetooth Smart, which works seamlessly with Suunto watches, fitness apps, and some third-party devices. Many users report quick and stable connections when paired with the Suunto 9 Peak, Suunto 5, and similar Suunto models.

However, connectivity with non-Suunto products is a frequent complaint:

“Tried to get my Suunto HR belt to work with my Garmin Edge—no dice. Ended up getting a dual-band (Bluetooth & ANT+) HRM from Wahoo instead.” — r/Triathlon

This is a valid concern, as many competitors (such as Garmin’s HRM-Pro or Polar H10) offer dual-band transmission (Bluetooth + ANT+), making them more versatile for multi-device setups. 

One thread in r/cycling emphasized how this limitation makes the Suunto Smart Belt less appealing for multisport athletes who use bike computers, Zwift, or other fitness ecosystems beyond Suunto’s. Some users ended up switching to Polar H9/H10 simply due to broader compatibility.

Durability & Comfort: "Decent, But Strap Wear is an Issue"

A key concern with chest HR monitors in general is strap durability, and Suunto’s strap is not immune to this issue. Several Redditors have mentioned that the elastic strap can loosen over time, especially with frequent use and sweat exposure.

A post in r/triathlon noted:

“Love the accuracy, but after 1.5 years, the strap has started stretching out and needed replacement. Not unusual, but annoying given the cost.”

This isn’t necessarily a dealbreaker, as straps from Garmin and Polar also face similar wear-and-tear. However, availability of replacements has been cited as an inconvenience:

“Finding a replacement strap for Suunto isn't as straightforward as with Garmin or Polar. Wish they had more third-party options.” — r/OutdoorGear

Battery Life: "Reliable Yet Non-Replaceable Battery is a Bummer"

Unlike some other HRMs that use user-replaceable CR2032 coin batteries (such as Polar's and Garmin’s HR straps), the Suunto Smart HR Belt has an integrated, rechargeable battery. While users appreciate not dealing with battery swaps, opinions vary on whether this is a convenience or a long-term disadvantage.

A user from r/Fitness wrote:

“Runs for ages on one charge, but eventually, like all rechargeable batteries, it’ll degrade. I wish they had an easy way to swap out batteries when needed.”

For some users, this means they feel forced to buy a new device once battery lifespan drops significantly, making long-term ownership more expensive.

Price & Value: "Good for Suunto Users, But Better Options Exist"

At its price point (typically $80-$100 USD), the Suunto Smart Heart Rate Belt is positioned in the mid-to-premium range. 

Many Suunto watch users find it a logical and worthwhile purchase, as it seamlessly integrates with their ecosystem:

“If you have a Suunto watch, this belt just works. No fuss, no weird pairing issues, and data syncs neatly into Suunto app.” — r/Suunto.club

However, users comparing HRMs on a brand-agnostic basis often gravitate toward either the Polar H10 (for best accuracy and comfort) or Garmin HRM models (for compatibility with ANT+ and Garmin ecosystem features).

A common conclusion on r/endurance:

“Unless you’re tied into Suunto already, I’d go for Polar H10 instead. More compatible, just as accurate.”

Final Verdict: Is It Worth It?

Pros:

✅ Accurate HR readings, especially compared to wrist-based monitoring  

✅ Works flawlessly with Suunto watches and apps  

✅ Rechargeable battery lasts a long time between charges  

Cons:

❌ Does not support ANT+, limiting compatibility with non-Bluetooth fitness gear  

❌ Straps may wear out over time, and replacements aren’t as widely available  

❌ Rechargeable battery degradation over time could force an eventual full replacement  

For users who already own a Suunto watch and prioritize ease of integration, the Suunto Smart Heart Rate Belt is a solid choice. However, those looking for maximum device compatibility or long-term durability might be better off considering Polar H10 or Garmin HRM-Pro.
