Resumen
The 30-Second Version
The Jxrev J51 nails comfort and battery for very little money, but the case is maddening and the ANC doesn't work. Buy them for casual listening if you can snag them under $20, just know you'll be fighting the case daily.

Performance
The 13mm drivers push a warm, bass-heavy sound that sits well above average for the price bracket. Battery life is strong, with 7 hours on the buds and 32 total in the case, and USB-C fast charging tops things off quick. The ANC is listed, but don't get excited. Owners consistently report it's mostly marketing, doing little to hush the outside world. Bluetooth 5.4 pairs fast, though you might get the occasional dropout. Call quality is rough; the mics pick up too much background noise, so don't plan conference calls on these. Build quality is where things dip hard, cheap plastic and a case you'll want to throw across the room when you can't pry the buds out.

vs Competition
Against the JLab GO POP ANC, the J51 wins on comfort but loses on build and touch control reliability. The Soundcore P31i has more honest ANC and better call quality. If fitness is your thing, the JBL Endurance Race 2 fits more securely and handles sweat better, even if it costs a bit more. The EarFun Air Pro 4i outclasses the J51 in microphone clarity, but these are often pricier. For the absolute lowest spend, the J51 holds its own, but spending another $10-20 sidesteps most of its flaws. If you're eyeing the premium end, the Technics EAH-AZ100 and Sony WF-1000XM6 are in a different universe entirely, but they make the J51's rough edges feel even sharper by comparison.

Value & Pricing
At under $20, you're getting a lot of comfort and battery for not much cash. The sound quality is genuinely enjoyable for casual listening, and that tiny case slips into any pocket. But you have to accept the big annoyances: a frustrating case design, fake-feeling ANC, and a build that won't survive rough handling. If you can live with those, it's a solid value, just don't expect miracles.

Overview
The Jxrev J51 is one of those rare budget finds that gets a few things spectacularly right and a few things spectacularly wrong. It's tiny, it's bright yellow, and it's shockingly comfortable, especially if you've got smaller ears. You'll get a full workday of battery and decent-enough sound for the price. But the very first thing you'll do is fight the case, and that tussle sets the tone.
Common Questions
Q: Does the active noise cancellation actually work?
Not really. Despite being listed as ANC, user feedback and our testing show it's more like very light passive isolation. Don't count on it to block out much background hum.
Q: Are these earbuds good for running and gym workouts?
They have an IP7 waterproof rating, which is great for sweat, but the fit can be insecure for some during movement. If they stay in your ears, they'll survive, but a more secure sports design might work better.
Q: Can I use them for phone calls?
We wouldn't recommend it. The microphone quality is below average and tends to pick up a lot of environmental noise, so your voice may sound distant to callers.
Who Should Skip This
If you need clear call quality or actual noise cancellation, skip these. Runners and gym-goers with larger ears might find them slipping out, and anyone who values build quality will be disappointed by the cheap plastic and painful case. Spend a touch more for fewer headaches.
Verdict
Grab these if you want dirt-cheap earbuds for podcasts and background music and don't mind wrestling the case open every time. The comfort is genuinely top-tier, but the rough edges make them a tough sell for anyone needing reliable calls or real ANC. With the price bump, the case frustration stings a little more.
