Sony WI-C100

The Sony WI-C100 delivers a 25-hour battery and top-tier comfort for under $40, making it one of the best budget neckband options we've seen. Sound and ANC are solid but not spectacular, and call quality is a genuine weak spot. At $29 on Amazon, it's a steal for commuters and gym-goers. Skip it if you take lots of calls or want premium audio.

Battery life is the headline act here. Sony claims 25 hours, and our data puts that at the 94th percentile across all in-ears we track. That's genuinely impressive for a pair of earbuds this cheap. The 10-minute quick charge giving you 60 minutes of playback is also a nice touch, though it's worth noting that's Sony's claim, not something we've independently verified. Still, even if real-world usage lands a bit short, you're looking at multiple days of heavy listening between charges.

Sound quality sits at the 70th percentile, which translates to "solid but not spectacular." The 9mm dynamic drivers handle the 20Hz-20kHz range competently, and DSEE does a decent job of restoring some life to compressed audio. But don't expect the kind of detail or soundstage you'd get from Sony's higher-end offerings. The ANC is similarly middle-of-the-pack at the 74th percentile. It'll take the edge off background noise on a bus or in an office, but it won't create a cone of silence. For the price, that's about what you'd expect.

The Soundcore P31i is probably the closest competitor here. It's also a neckband design with a similar price point, and Anker's sound tuning tends to be a bit more bass-forward. If you want punchier low-end, the P31i might edge out the Sony. But the WI-C100 counters with better comfort and that Sony DSEE processing, which helps with older or lower-bitrate files. It's a toss-up depending on your priorities.

The EarFun Air Pro 4+ and Nothing Ear (3) are different beasts entirely. Those are true wireless earbuds with charging cases, and they cost more. The Nothing Ear (3) especially is aimed at a more design-conscious buyer. If you want the absolute best ANC or the most modern form factor, those are worth a look. But neither matches the WI-C100's battery life, and both cost significantly more. The Anker Space A40 is another true wireless option with better ANC, but again, you're paying for it.

Here's where things get interesting. The WI-C100 lists at $29 to $40 depending on where you shop, with Amazon.com showing the lowest price at $29. That's a $11 spread across US listings, which is worth paying attention to. For context, the CAD price sits at $28, which is a different currency and not directly comparable, but the point stands: this is budget territory.

At $29, the value proposition is hard to argue with. You're getting a 25-hour battery, decent sound, and Sony's build quality for less than the cost of a decent dinner. The 80th percentile build score suggests these won't fall apart after a few months, which is a common concern with cheap earbuds. If you're comparing against the Soundcore P31i or JLab JBuds Pods, the Sony holds its own on battery and comfort while undercutting some of them on price.

The Sony WI-C100 is one of those products that makes you wonder why neckband earbuds ever fell out of fashion. For under $40, you're getting a pair of wireless in-ears with a 25-hour battery, IPX4 splash resistance, and Sony's DSEE audio processing. That's a spec sheet that would've cost you triple a few years ago. The neckband form factor isn't for everyone, but if you're tired of losing individual earbuds or dealing with charging cases, this thing solves real problems.

Who's this for? Commuters, gym-goers, and anyone who listens to audio for long stretches and doesn't want to think about battery anxiety. The 25-hour rating puts it in the top tier of our database for battery life, and the comfort score lands at the 95th percentile. That's not marketing fluff, that's measured against hundreds of other in-ears we've tracked. The flexible neckband means you can pop these off and let them hang when you're not listening, which is genuinely handy.

But let's be real about what this isn't. The ANC here is fine, not great. Call quality is the weakest link at 67.1 out of 100. And the design language screams "practical" more than "premium." If you want the absolute best sound or the most polished experience, there are better options. If you want something that just works, lasts forever on a charge, and won't break the bank, the WI-C100 makes a strong case.

If you take a lot of phone calls, the WI-C100 is not for you. The call quality score of 67.1 out of 100 is the weakest area of this product, and the single mic with noise cancellation struggles in anything but quiet environments. For frequent callers, look at the Anker Space A40 or Nothing Ear (3), both of which have better mic performance.

Audiophiles should also look elsewhere. The 70th percentile sound score means these are good, not great. If you want detailed, nuanced audio, you'll need to spend more on something like the EarFun Air Pro 4+ or step up to Sony's higher-end offerings. The WI-C100 is about convenience and battery life, not critical listening.

For commuters and gym-goers on a budget, the WI-C100 is an easy recommendation. The 25-hour battery means you can go days without charging, the IPX4 rating handles sweat and rain, and the comfort is genuinely best-in-class. At $29, it's hard to find a better value in wireless audio.

But if you take a lot of calls, look elsewhere. The 67.1 call quality score is a real weakness, and the single mic with noise cancellation just doesn't cut it in noisy environments. Similarly, if you're an audiophile who wants the best possible sound, the 70th percentile sound score means you'll be left wanting more. For everyone else, the WI-C100 is a solid, dependable choice that punches above its price tag.
