Monoprice 133834

★★★★☆ 3.6 (4)

Support for Qualcomm aptX audio over Bluetooth 5.0 delivers higher-quality wireless streaming than standard SBC codecs at this price point. The foldable design and included 3.5mm wired option add practical flexibility, though the 16-hour battery life trails many competitors. These are best for budget-conscious listeners who want ANC and aptX codec support for casual music and video playback, not for critical studio monitoring or frequent call use.

Snapshot

The 30-Second Version

These sound like a million bucks but feel like a vice grip. Buy them only if you prioritize audio quality above all else, including your own comfort.

Pros & Cons

Pros

  • Shockingly good sound quality for the price 94th
  • aptX support is a real bonus 81st
  • ANC performance is well above average 77th
  • Foldable design is handy for travel 75th

Cons

  • Abysmal comfort, one of the worst we've tested
  • Battery life is a disappointing 16 hours
  • Micro-USB charging in this day and age is a crime
  • No detachable audio cable included in the box

The proof

Performance

The sound quality is the real shocker here. A 94th percentile ranking for audio performance at this end of the market is almost unheard of. The 40mm Neodymium drivers, paired with aptX support, deliver a clarity and punch that completely outclasses the price tag. It's not just good for the money, it's one of the best on the market in our sound tests. The ANC is also a pleasant surprise, landing well above average and effectively hushing background hum. But all that good work is undone the moment you put them on. The comfort score is a brutal 6th percentile, one of the worst we've seen. The clamping force and pad material make long listening sessions a non-starter.

vs Competition

The Soundcore Life Q20 is the obvious and better alternative for most people. It's the benchmark for budget ANC headphones, and while it won't touch the Monoprice's sound quality, it's infinitely more comfortable and has double the battery life. The JBL Tune 670NC is another solid pick that nails the basics of comfort and battery without the sonic fireworks. The Monoprice BT-300ANC is for the audio purist on a razor-thin budget who's willing to suffer for their music. For everyone else, the compromises are too steep.

Value & Pricing

The value proposition here is a total rollercoaster. The price spread we're seeing is insane, from a reasonable $55 all the way up to a ludicrous $14,875 from some third-party sellers. If you can snag these from a reputable retailer at the lower end of that range, the sound quality alone almost makes them worth it. Almost. But that 16-hour battery life and the physical discomfort are major, daily-use dealbreakers that cheapen the experience.

Overview

The Monoprice BT-300ANC is a weird one. On paper, it throws out some seriously impressive numbers for the price, especially in sound quality where it lands in the 94th percentile of our database. That's genuinely top-tier stuff. But then you look at the battery life and comfort scores, and the whole picture gets a lot murkier. The one thing to know is this: these headphones sound fantastic for the money, but they're a chore to actually wear for more than an hour.

Common Questions

Q: Does it come with a cable for wired listening?

Nope. The box only includes a Micro-USB charging cable. You'll need to buy a separate 3.5mm audio cable if you want to use them wired, which is a pretty annoying omission.

Q: How long does the battery actually last?

You're looking at around 16 hours with ANC on. That's pretty weak by modern standards where 30-40 hours is common. You'll be reaching for that ancient Micro-USB charger a lot more often than you'd like.

Who Should Skip This

If you plan on wearing your headphones for an entire workday, a long flight, or even just a full album without fidgeting, these aren't it. The comfort is a dealbreaker. Go get the Soundcore Life Q20 instead. You'll lose some audio magic, but you'll gain the ability to actually wear them.

Verdict

We can't recommend the Monoprice BT-300ANC for most people. The sound is genuinely brilliant, a real standout that embarrasses headphones costing much more. But headphones are something you wear, and these fail at the most fundamental part of the job. The dreadful comfort and short battery life turn what could have been a legendary budget king into a deeply flawed curiosity. Unless you only listen in 45-minute bursts and never move your head, look elsewhere.
