Edifier NB2 Pro
The hybrid ANC with dual-MIC delivers up to -38dB of noise reduction, and it works even without music playing. The 32-hour total battery with 15-minute fast charging for 2 hours of listening, plus IP54 dust and water resistance, makes it practical for daily commutes and workouts. Best for gamers and travelers who want reliable noise cancellation and long battery life, though fitness users may find the fit less secure.

Snapshot
The 30-Second Version
The NB2 Pro is a battery beast with great mics, but the sound and build don't match the price. Buy it for calls and battery life, not for music.

- Battery life is absurdly good, 32 hours total 98th
- Six mics make calls surprisingly clear 97th
- ANC works even without music playing 93rd
- IP54 rating means sweat and rain are no problem 93rd
Cons
- Build quality feels flimsy
- Sound is just okay, nothing special
- Fitness score is terrible at 38.6/100
- No wireless charging
What owners think
The Word on the Street
The proof
Performance
The battery life is the real showstopper here. At 32 hours total, it sits in the 98th percentile of our database, which is basically best-in-class territory. The six-mic setup also impressed us, landing in the 97th percentile for call quality. But the sound is just average, and the build feels a bit cheap compared to the competition. The ANC is strong at -38dB, but it's not quite on par with Sony or Apple.

vs Competition
The Sony WF-1000XM6 and Apple AirPods Pro 3rd Generation both beat the NB2 Pro on sound quality and build, but they'll cost you more. The Technics EAH-AZ100 is a closer match on battery life, but it's also pricier. If you want to save some cash, the Soundcore P31i or EarFun Air Pro 4+ offer similar features for less money, though their battery life doesn't come close.

Price
Value & Pricing
At $273 USD, the NB2 Pro is a tough sell. You're paying near-flagship prices for a pair of earbuds that don't quite deliver flagship sound or build quality. But if battery life and call quality are your top priorities, it's hard to find better at this price.

Overview
The Edifier NB2 Pro is a bit of an odd duck. It packs flagship-level battery life and surprisingly good mics into a budget-friendly package, but the build quality and overall polish don't quite match the spec sheet. The one thing to know? If you want all-day battery and solid call quality without spending Sony money, this is a serious contender.
Common Questions
Q: How long does the battery actually last?
You'll get around 32 hours total with the case, which is one of the best numbers we've seen. A 15-minute quick charge gives you about 2 hours of listening.
Q: Are these good for working out?
Honestly, no. They scored a 38.6/100 for fitness, which is pretty rough. The IP54 rating helps with sweat, but the fit isn't secure enough for intense workouts.
Q: Can I use them for phone calls?
Yes, and they're actually great for calls. The six-mic setup puts them in the 97th percentile for mic quality, so your voice will come through clear.
Who Should Skip This
If you're looking for top-tier sound quality or a premium build, this isn't it. Go get the Sony WF-1000XM6 or Apple AirPods Pro 3rd Generation instead. And if you're a gym rat, skip these entirely and grab something with a better fitness score.
Verdict
The Edifier NB2 Pro is a niche product. If you're a heavy caller who needs all-day battery and decent ANC, it's a solid choice. But for most people, the mediocre sound and flimsy build make it hard to justify the price. You're better off spending a bit more on Sony or Apple, or saving money with Soundcore.
