Belkin SoundForm Rhythm AUC012BTBK

The Belkin SoundForm Rhythm looks killer on paper with Bluetooth 5.3, multipoint, ANC, and 28-hour total battery, but real-world owners report constant audio dropouts and random auto-connections that sour the deal. Our sound tests place music quality in the 28th percentile, so don't expect audiophile chops. Prices are an absurd rollercoaster from $21 to $3,990, meaning you might find a steal if you hunt hard. For most people, though, spending a few more bucks on an EarFun or Soundcore bud pays off in sanity.

Belkin's SoundForm Rhythm buds land on your doorstep with a spec sheet that reads like a bargain hunter's dream: Bluetooth 5.3, multipoint, ANC, IPX5 water resistance, and a battery that's supposed to last all day. The price tag, at least from some storefronts, is laughably low, while other retailers seem to be living on another planet with listings north of three grand. On paper, these are the earbuds you toss in your gym bag and forget about, until you need a quick podcast or a call. But here's the thing: the real story isn't the features, it's the disconnect between what's promised and what actually happens once you pair them.

We dug into our database and user feedback from across the web, and the picture is messier than a tangled USB cable. The connectivity ranking sits at a sky-high 97th percentile, which suggests best-in-class wireless chops, and the build quality is right up there at 91st. Yet the people who actually bought them keep talking about audio dropouts, random connections to strangers' phones, and a total lack of app support. That's a weird mismatch, and it gets weirder when you look at sound. Our objective benchmarks put music quality at a mediocre 35.5 out of 100, but a chunk of owners genuinely praise the sound. Something's off, and we're here to sort it out.

If you're someone who glimpses a feature list and clicks buy, you might be tempted. But if you rely on earbuds for meetings, gym sessions without interruption, or just want something that doesn't make you want to chuck them out the window, keep reading. We're going to break down where the Rhythm sings and where it trips over its own feet, using real numbers and real owner sentiment, not just the marketing slides.

Our lab benchmarks paint a surprising portrait. The connectivity percentile is 97th, a score that usually means bulletproof pairing and rock-solid streaming. But that score is based on the raw tech, Bluetooth 5.3 and multipoint support, not real-world reliability. And real-world reports tell a different story: constant signal loss between left and right earbuds, and unwanted auto-connections to unknown devices. So yes, the chipset is modern and the multipoint feature is genuinely useful when it works, but the implementation feels half-baked. Battery life lands in the 78th percentile, meaning an honest 8 hours from the buds and 28 total with the case, plus that speedy 10-minute charge for 90 minutes of playtime. That's solid and one of the few areas where spec and experience align.

Sound quality is the biggest letdown in our testing. At the 28th percentile, it's well below average for true wireless earbuds, even budget ones. The Belkin Signature Sound tuning comes across as boomy and muffled, with treble that gets harsh at higher volumes. We measured weak instrument separation and a flabby low end that smothers vocals. That said, a subset of users in the wild actually describe the sound as 'great' or 'loud', which suggests that if you're mainly listening to spoken word or bass-heavy playlists at moderate levels, you might not mind. But for music fans, the SoundCore P31i or EarFun Air Pro 4+ deliver far clearer audio. Noise cancelling sits at the 80th percentile, so ANC performance is decent for the price, reducing low-end hum on a commute, though it won't rival a Samsung Galaxy Buds3 Pro. Call quality, backed by ENC, is average at the 66th percentile, the mic does an okay job in quiet rooms but struggles with wind and chatter.

Pricing for these earbuds is a circus. We've seen them listed for as little as $21 from one seller and a baffling $3,990 from another, so the real market price probably sits somewhere in the $40 to $60 range. If you can snag them at the extreme low end and you're willing to gamble on connection quirks, the value proposition flips. For $21, you're getting ANC, multipoint, and a durable build that would embarrass a lot of cheap no-name buds. But at $60, you're perilously close to the EarFun Air Pro 4+, which packs a polished app, superior sound, and way more reliable wireless performance. The $21 price is the only scenario where the Rhythm makes any sense, and even then, you're buying a lottery ticket of connectivity frustration.

Given the massive spread, we can't point to a single store name as the guaranteed best deal, but it's worth shopping around and reading return policies closely. Because if you end up with a pair that drops signal every five minutes, that bargain price will feel like a rip-off. We'd say if you're spending more than $30 on these, you're better off putting that cash toward a more consistent budget champion like the Soundcore P31i, which often dips below $40 during sales.

The most direct competitor is the EarFun Air Pro 4+, which lands around $60 and matches the Rhythm on ANC and IPX5 while adding an excellent app, more refined sound, and dependable connectivity. EarFun's buds earned high marks in our database for both audio clarity and call quality, and they don't suffer from the dropout gremlins that haunt the Belkin. If you value a set-and-forget experience, the Air Pro 4+ is the smarter buy. Samsung's Galaxy Buds3 Pro sits at a much higher price but offers best-in-class ANC and transparency mode, plus seamless integration with Samsung phones. Not a fair fight on price, but worth mentioning if you're already in the Galaxy ecosystem and can stretch the budget.

For sporty types, the JBL Endurance Race 2 delivers an arguably more comfortable and secure fit without the bulk, though it trades ANC for passive isolation. The TOZO Crystal Pods come in even cheaper and deliver shockingly crisp sound for the money, but they skimp on multipoint and build refinement. The Belkin's standout feature, then, is its multipoint connectivity, which is genuinely useful if you hop between a laptop and phone often. But the Soundcore P31i offers the same trick with more polished execution and a full app, making it a better pick for that specific need. Essentially, the Rhythm only wins if you can't spend a dollar more and gamble on the connection lottery.

If you rely on earbuds for phone calls, video meetings, or any scenario where a dropped connection is more than a minor annoyance, skip the Rhythm entirely. The audio signal loss is too frequent and too random to trust, and that alone disqualifies them for work use. Anyone who wants an app to tweak sound or update firmware should look elsewhere, the Belkin offers nothing. And if you have small ears, the chunky build and mediocre comfort score will likely lead to constant fidgeting. You're better off with the EarFun Air Pro 4+ for a polished all-rounder or the Soundcore P31i for reliable multipoint on a budget. Even if you find the Rhythm at a fire-sale $21, the headache might not be worth the savings if stability matters at all.

For the budget-obsessed gym-goer who just wants beater earbuds that can survive a workout and rarely needs rock-solid call quality, the Belkin SoundForm Rhythm could scrape by, but only if you find them under $30 and you're ready for occasional dropouts. The IPX5 rating and long battery life are real assets here, and if you're mainly streaming podcasts where a momentary signal blip won't ruin your day, you might not mind. But we can't give a blanket recommendation to anyone who uses earbuds for music, work calls, or simply expects their gear to work without babysitting.

If you need reliable multipoint for switching between your work laptop and phone, the Soundcore P31i does it better and sounds cleaner for a similar street price. If sound quality is your priority, even a slight budget bump to the EarFun Air Pro 4+ or the surprisingly capable TOZO Crystal Pods will transform your listening experience. The Belkin Rhythm feels like a prototype that got rushed to shelves: the bones are good, the feature list is ambitious, but the software and QA just aren't there. Unless that rock-bottom $21 price appears and your expectations are ground-level, you should probably skip.
