Betron Betron B25 Earphones, Noise Isolating in-Ear Wired Review
The Betron B25 wired earbuds deliver bass-heavy sound and great noise isolation for just $15. They're a fantastic value, as long as you never need to use the microphone.
The 30-Second Version
For $15, the Betron B25s deliver shockingly good bass-heavy sound and excellent noise isolation. They're incredibly comfortable and well-built for the price. Just don't use them for phone calls. At this price, they're an easy recommendation for anyone who still uses a headphone jack.
Overview
The Betron B25 are cheap wired earbuds that punch way above their price tag. For about $15, you get a solid, bass-heavy sound profile and surprisingly good noise isolation that makes them perfect for the gym or commuting.
They're not trying to be audiophile gear. They're a simple, reliable pair of buds you can toss in a bag and not worry about. The tangle-free cord and included case are nice touches for the price, and they work with any device that still has a headphone jack.
Performance
The sound is the main event here. It's bass-forward, which our data shows lands in the 85th percentile for sound quality in this category. That means they're genuinely good for the money, especially if you listen to hip-hop, EDM, or anything where low-end matters. The noise isolation is also a standout, scoring in the 86th percentile. They block out a lot of ambient noise passively, which is impressive for a non-ANC bud. The big weakness is the microphone. It scores in the 36th percentile, so calls sound thin and distant. These are for listening, not talking.

Value & Pricing
At $15, the value is almost absurd. You're getting sound and comfort that rivals buds two or three times the price. The trade-off is in features and call quality. If you just need a reliable pair of wired earbuds for music and podcasts, and you don't mind being plugged in, it's hard to find a better deal. They're disposable in the best possible way.
vs Competition
Compared to other budget options, the B25s win on pure sound and comfort. They easily outclass the basic earbuds that come with your phone. Against something like the Anker Soundcore P31i, you lose wireless convenience and a better mic, but you gain better passive isolation and save a bunch of cash. If you're looking at the Nothing Ear (a), you're in a different league entirely—that's a wireless ANC bud. The Betrons are for people who want the simplest, cheapest path to good sound.

Common Questions
Q: Do these have a built-in microphone for calls?
Yes, there is a basic inline mic, but it performs poorly. Our data ranks call/mic quality in the bottom 36th percentile, so they're not recommended for frequent phone use.
Q: Will these work with my iPhone that only has a Lightning port?
Not directly. You'll need a separate Lightning to 3.5mm headphone jack adapter, which Apple sells separately.
Q: How is the noise cancellation?
They don't have active noise cancellation (ANC). Instead, they use a tight seal and noise-isolating design, which our tests show is very effective, ranking in the 86th percentile for blocking ambient sound passively.
Who Should Skip This
Skip these if you need a reliable headset for calls or video meetings. The mic is bad. Also, look elsewhere if you want wireless freedom or advanced features like an inline remote. This is a barebones, wired-only experience.
Verdict
Buy these if you need a cheap, no-fuss pair of wired earbuds for the gym, commute, or just listening at your desk. They're perfect for anyone who loses or breaks earbuds regularly and doesn't want to spend a fortune. The sound and comfort are fantastic for the money, and the noise isolation is a real bonus.
