Opinión de los propietarios

The Word on the Street

4.4/5 (2452 reviews)
👍 Owners can't stop talking about the sound quality, with many switching from expensive Sony and Bose earbuds and not looking back.
👎 A small but vocal group reports that their buds died after a few months, pointing to long-term durability as a question mark.
🤔 The plastic build gets called out as cheap, but most agree it's a fair trade-off to hit this price.

Performance

We plugged these in expecting 'decent for the money.' Instead, we got ANC that swallows office chatter and low-end rumble almost on par with earbuds costing four times as much. The 11mm dynamic driver plus 6mm tweeter combo delivers clear treble and thumping bass that doesn't muddy the mids, and the LDAC codec means you're actually getting high-res detail over Bluetooth. Call quality surprised us too—the six-mic array with Clear Voice 3.0 made us sound natural even with street noise in the background. Battery life is a marathon: 11 hours in the buds and 43 total with the case, plus Qi wireless charging. The only performance hiccup is a slight hiss in transparency mode when it's very quiet, but for most people that's nitpicking.

vs Competition

The Sony WF-1000XM6 and Bose QuietComfort Ultra both offer more polished builds, waterproofing, and slightly more refined apps, but they cost four to five times as much and don't actually outperform the CMF in ANC or battery. The Technics EAH-AZ100 and Google Pixel Buds Pro come closer in polish, yet the CMF's dual-driver sound and smart dial give it an edge. If you're willing to trade a bit of app sophistication for raw performance per dollar, the Buds Pro 2 are the clear winner.

Precio

Value & Pricing

At the $49 street price, these are an absolute steal. You're getting ANC, sound, and battery life that handily beat many earbuds in the $150 to $200 range. Unless you absolutely need a premium metal build, there's no reason to spend more.

Overview

The CMF Buds Pro 2 are the kind of earbuds that make you question every dollar you've ever spent on audio. For around $60, you get a dual-driver setup, LDAC high-res streaming, and 50dB adaptive noise canceling that lands in the top 3% of all earbuds we've tested. The sound is crisp, bass-forward, and customizable through the Nothing X app, and the case has a genuine party trick: a clickable smart dial that handles volume, playback, and ANC modes without pulling out your phone. Yeah, the plastic build feels a bit hollow, but the feature set here is borderline absurd for the price.

Common Questions

Q: Do these have wireless charging?

Yep, the case supports Qi wireless charging. You can also top up via USB-C, and a 10-minute quick charge gives you 3 hours of listening.

Q: How's the call quality in noisy places?

Really solid. The six mics and Clear Voice 3.0 filter out background chaos and make your voice come through clearly. It's way better than most sub-$100 earbuds.

Q: Is there a low-latency mode for gaming?

Yes, you can enable it for around 120ms latency, which is fine for casual gaming and videos. Competitive mobile gamers might notice a slight delay, but it's perfectly watchable.

Who Should Skip This

If you're rough on your gear and want a metal unibody feel, skip these. The plastic shell and occasional pocket dial misfires will annoy you. Grab the Sony LinkBuds Fit for a tougher build, or the Samsung Galaxy Buds3 Pro if you're deep in that ecosystem and willing to pay the premium.

Verdict

These are the budget earbuds to beat right now. The sound is lush, the ANC is best-in-class for the price, and the battery just keeps going. At $49, it's not even a conversation. Unless you're particularly rough on your gear and need a tank-like build, buy these without a second thought.
