Belkin Soundform Rhythm AUC015fqBK

★★★★★ 4.5 (34)

Four microphones with Clear Call technology and active noise cancellation from 10mm drivers, paired with Bluetooth 5.4 multipoint, prioritize voice clarity and seamless device switching. At just 1 gram per earbud and IPX5 water resistance, it delivers near-weightless comfort that endures sweat and rain. This suits gym-goers and on-the-go professionals who need reliable call performance and ANC during workouts, not critical music listening.

The proof

Performance

The 10mm dynamic drivers push sound from 20Hz to 20kHz, but the music score tells the real story. It's not a detail monster. Bass is present but not punchy, and the mids can feel a bit flat. Where these shine is everything around the sound. ANC lands in the 86th percentile, which is genuinely impressive for budget buds. The four-mic array with noise cancellation sits even higher, making calls surprisingly clean. Battery life is solid at 8 hours from the buds and 20 more from the case, with fast charge support when you're in a rush.

vs Competition

Against the Sony WF-C700N, the Belkin wins on connectivity and mic quality but loses badly on sound. The Sony is the better pick if music matters. The Anker Space A40 offers stronger overall balance and better brand trust, but costs more. The EarFun Air Pro 4+ is the closest rival on features, with comparable ANC and better audio tuning. The Soundcore P31i and JLab JBuds Pods ANC are cheaper but feel cheaper too. Belkin sits in a sweet spot for call-heavy users who don't want to pay Sony prices.

Value & Pricing

At around 30 USD in the US, these are a steal. You're getting ANC, multipoint Bluetooth, and call quality that competes with buds costing twice as much. The music performance is the trade-off, but if you're not an audiophile, you probably won't care. For gym use, commuting, and taking calls, this is excellent value.

Overview

The Belkin Soundform Rhythm is one of those earbuds that quietly overdelivers. You get active noise cancellation, Bluetooth 5.4 with multipoint, and a four-mic call setup for a price that sits well below most big-name competitors. Belkin isn't exactly the first brand people think of for true wireless audio, but these make a solid case.

Our database puts the connectivity and mic quality near the top of the charts, which is rare at this price. The weak spot is music. A 42.9 out of 100 for music means these are better suited for podcasts, calls, and gym sessions than critical listening.

Common Questions

Q: Are these good for working out?

They have IPX5 water resistance, so sweat and light rain won't kill them. But several owners report the fit can slip during intense exercise, so they're better for lighter activity or gym sessions where you're not bouncing around.

Q: How is the call quality?

Call quality is one of the strongest features here. The four-microphone array with noise cancellation puts these in the 92nd percentile in our database, so your voice comes through clearly even in noisy environments.

Q: Can I connect to two devices at once?

Yes. Bluetooth 5.4 with multipoint lets you stay connected to your phone and laptop simultaneously, which is rare at this price and a big plus for anyone who juggles devices during the day.

Who Should Skip This

Skip these if music quality is your top priority. The sound score is mediocre, and you'll notice the flat mids and lack of detail if you're used to better-tuned buds. Also skip if you need earbuds that stay put during high-intensity workouts, the fit just isn't secure enough when things get sweaty.

Verdict

Buy these if you take a lot of calls, want solid ANC, and don't need audiophile-grade music. They're comfortable, durable, and the battery life is more than enough for a full day. Skip them if you're picky about sound quality or need buds that stay locked in during intense workouts.
