Snapshot

The 30-Second Version

The Belkin SoundForm ClearFit scores 52.8 out of 100 overall, with connectivity at the 96th percentile as its standout feature. The open-ear design and IPX5 rating make these a solid gym companion, but comfort at the 29th percentile and a commute score of 34.3 mean they're not for everyone. At 4.5 stars from 52 reviews, owners are happy, but your ears might disagree.

The proof

Performance

The 14.2mm dynamic drivers are the biggest single driver we've seen in this category, and they deliver a sound score at the 63rd percentile. That's solid, not spectacular. Belkin's Signature Sound tuning leans into bass, which makes sense for workout buds, but the open-ear design means you're never getting a sealed, punchy low end. You'll hear your music clearly, but don't expect the kind of isolation that makes bass feel physical.

Connectivity is where these genuinely shine. The 96th percentile ranking puts them among the best we've tested for staying connected. Bluetooth 5.3 with multipoint means you can pair to your phone and laptop simultaneously, and the 30-foot range is reliable in real-world use. Battery life is respectable at 8 hours in the buds and 18 more in the case, landing at the 70th percentile. The fast charge is a nice touch, 10 minutes gets you 1.5 hours, which covers a forgotten charge before a workout. The mic setup with 2 mics and noise cancellation scores at the 82nd percentile, so calls are actually decent for open-ear buds.

vs Competition

Against the Sony WF-1000XM6 and Bose QuietComfort Ultra, the ClearFit gets absolutely demolished on ANC and sound isolation. Those two are closed-back noise-canceling champs, while the ClearFit's open-ear design is a completely different product philosophy. The 31st percentile ANC score tells the story. But here's the thing, the ClearFit's 96th percentile connectivity actually beats what we've seen from some of those premium competitors. The Technics EAH-AZ100 and Anker Space A40 both offer better overall sound and comfort, but they're also closed designs. If you specifically want open-ear awareness for running or cycling, the ClearFit competes more directly with the Soundcore P31i, and the Belkin's connectivity and mic quality give it an edge there.

Value & Pricing

Pricing is all over the map depending on where you shop. The INR 4,999 listing in India and JPY 4,998 in Japan are roughly equivalent in their local markets, while the MXN 1,399 listing in Mexico suggests some serious regional price variation. Without a consistent baseline, it's hard to call these a screaming deal, but the connectivity performance at the 96th percentile means you're getting flagship-level pairing reliability at budget earbud prices. The 4.5-star rating from 52 reviews suggests most buyers feel they got their money's worth.

Overview

The Belkin SoundForm ClearFit lands at 52.8 out of 100 in our database, which puts it firmly in the middle of the pack for open-ear earbuds. The headline here is connectivity, sitting at the 96th percentile. Bluetooth 5.3 with multipoint for two devices is genuinely top-tier stuff, especially at this price point. But the comfort score of 29th percentile is a red flag we can't ignore, and the commute score of 34.3 out of 100 tells you exactly where these fall short.

These are fitness-first earbuds with a 57.6 fitness score, and that's where they make the most sense. The IPX5 rating means sweat and rain won't kill them, and the open-ear design keeps you aware of traffic or gym chaos. But if you're buying these for calls or commuting, the 53.3 call score and that weak commute number should give you pause. The 4.5-star rating from 52 reviews suggests owners are generally happy, but the comfort percentile says not everyone's ears agree.

Common Questions

Q: Are these good for running and working out?

Yes, the IPX5 rating means they handle sweat and rain, and the open-ear design keeps you aware of your surroundings. The fitness score of 57.6 out of 100 is solid for this category, and the 8-hour battery life covers even long training sessions.

Q: Can I connect these to two devices at once?

Yes, the Bluetooth 5.3 multipoint connection supports up to 2 devices simultaneously. This is actually the standout feature, with connectivity ranking at the 96th percentile in our database, so switching between your phone and laptop is seamless.

Q: How is the noise cancellation?

It's minimal. The ANC score sits at the 31st percentile, which is expected for open-ear earbuds. The design intentionally lets in ambient sound for awareness, so don't expect to block out a noisy commute. The commute score of 34.3 out of 100 reflects this limitation.

Who Should Skip This

If comfort is your top priority, look elsewhere. The 29th percentile comfort score is one of the weakest we've seen, and the silicone fit doesn't work for everyone's ear shape. Commuters should also steer clear, the 34.3 commute score and 31st percentile ANC mean you'll hear every screeching train brake and chatty seatmate. And if you want immersive, bass-heavy sound, the open-ear design at the 63rd percentile for sound won't satisfy. These are workout buds, not all-day companions.

Verdict

The Belkin SoundForm ClearFit is a niche product that nails its niche. If you want open-ear earbuds for workouts where situational awareness matters, the 57.6 fitness score and IPX5 rating make these a solid choice. The 96th percentile connectivity is genuinely impressive and the mic quality at the 82nd percentile means you can take a call mid-run without sounding like you're underwater. But the 29th percentile comfort score is a gamble, and the 34.3 commute score means these are not your all-day earbuds. Buy them for the gym, not the train.
