Sony Sony - USB-C Wired In-ear Headphones - Blue Review

These are $30 wired USB-C earbuds. Their best feature is not having a battery to charge. Sound quality is mediocre (36th percentile) and the microphone is bad (17th percentile). Only buy these if you prioritize simple, zero-hassle plug-and-play over everything else.

These are the Sony IER-EX15C, a simple pair of wired USB-C earbuds. They cost about $30, and they're built for one thing: plugging in and playing. There's no battery to charge, no Bluetooth to pair, and no latency to worry about. You just get sound, immediately. That's the whole pitch.

Our data shows they're a budget-focused product, scoring in the 27th percentile for that category. They're not trying to compete with high-end wireless models. Instead, they're aiming for the 'I just lost my earbuds and need something cheap and reliable' crowd. The main trade-off is clear: you're getting convenience and a low price, but you're giving up on features like active noise cancellation and wireless freedom.

Let's be real, the performance here is about simplicity, not specs. The 5mm drivers deliver sound that lands in the 36th percentile. That means it's fine for casual listening, but don't expect audiophile detail or earth-shaking bass. The microphone is the real weak spot, sitting in the 17th percentile. Our call quality tests confirm it's not great for noisy environments. On the upside, 'battery life' is a non-issue, which ironically gives it a 64th percentile score in that category because it never dies. Comfort is middle-of-the-road at the 55th percentile, helped by the included ear tips.

For $30, you're paying for a cable with earbuds attached. The value is entirely in the convenience of 'it just works' and the fact you'll never hunt for a charger. Price-to-performance isn't really a calculation here, because the performance is barebones. You're not getting great sound or a good mic for your money. You're getting a reliable, colorful audio dongle that won't let you down because it can't. If that's what you need, the price is right.

This is where it gets interesting. Stacked against its own 'Top Competitors' list, the EX15C is playing a different game. The Sony WF-1000XM5, Technics EAH-AZ80, and Bose QuietComfort Ultra are all premium wireless noise-canceling champs. They cost 5-10x more. The EX15C doesn't compete on sound, ANC, or features. Its real competition is other cheap wired earbuds, or maybe your phone's included pack-in headphones. Compared to those, it has a slightly better remote and Sony's name on it. Against the Jabra Evolve2 Buds (which are wireless but USB-C for charging), you lose all the business-centric features like a great mic. It's an apples-to-oranges comparison, and the EX15C is a very simple, affordable apple.

Skip these if you care about call quality, want immersive sound, or desire a wireless experience. The microphone's 17th percentile ranking makes it a poor choice for frequent calls or remote work. If sound quality is your main concern, the 36th percentile score means there are much better options even near this price. And obviously, if you want to cut the cord, this isn't it—its connectivity scores in the 10th percentile because it's literally attached to one.

We can only recommend the Sony IER-EX15C for a very specific, no-frills need. If you absolutely hate managing Bluetooth devices, need zero-latency audio for mobile gaming on a budget, or just want a reliable backup pair to throw in a bag, these are fine. The data is clear: they're mediocre at sound (36th percentile) and bad at calls (17th percentile). But for plug-and-play simplicity at $30, they deliver exactly what's on the box. Just don't expect more.
