How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want studio-style sound with a wired fallback and marathon Bluetooth battery life, choose Audio-Technica ATH-M20xBT; if you need built-in AM/FM radio and certified hearing protection for loud jobs like mowing, choose PROHEAR 033.
• Audio-Technica ATH-M20xBT — biggest strength: 40 mm dynamic drivers with rare earth magnets and copper-clad aluminum voice coils, tuned for mid-range definition and enhanced bass, with up to 60 hours of playback per charge and a detachable cable for wired listening. Biggest trade-off: no noise reduction and no radio — it isolates passively through its circumaural fit, nothing more.
• PROHEAR 033 — biggest strength: a genuine hearing protector first and a headphone second: 31 dB SNR (NRR 25 dB) with ANSI S3.19 certification, plus a built-in AM/FM tuner that stores 10 stations per band. Biggest trade-off: it's a work-safety tool, not an audiophile headphone — passive noise cancellation only, no active noise cancellation, and a bulkier ear-muff shape.
• Pick Audio-Technica ATH-M20xBT if you mainly listen to music, game, or take calls and want full-range audio with a wired option when the battery runs out.
• Pick PROHEAR 033 if you're mowing, in a workshop, or around machinery and want your ears protected while the radio or Bluetooth plays.
• One-line tiebreaker: sound quality and battery life favor the Audio-Technica; hearing protection and radio convenience favor the PROHEAR.
The ATH-M20xBT is the wireless version of a studio-monitor formula. The spec sheet reads like a listening tool: 40 mm dynamic drivers, rare earth magnets, copper-clad aluminum voice coils, a 5 Hz to 32,000 Hz frequency range, 36 ohm impedance and 100 dB sensitivity. In plain terms, that's a wide, full-range tuning with the mid-range definition Audio-Technica builds its M-Series reputation on, plus boosted low end for modern music. Bluetooth 5 is on board with a 10-meter range, and controls are touch-based with volume control built in.
Who should buy it: commuters, students, gamers, and anyone who wants one pair of over-ear headphones for music, calls and casual gaming with a wired backup. Who should skip it: anyone who needs actual noise protection around loud machinery, or who wants radio without a phone. The circumaural design seals around the ears for decent passive isolation, but there is no noise control feature listed — this is not a hearing protector, and you shouldn't treat it as one.
PROHEAR 033: Who It's For
The PROHEAR 033 is built for a completely different job. Its headline numbers are safety numbers: 31 dB SNR and NRR 25 dB, with ANSI S3.19 certification. The brand's own example makes it concrete — if ambient noise sits around 80 dB, roughly 55 dB reaches your ears. That's the difference between a noisy mower and a manageable hum. If you've ever finished an afternoon of yard work with ringing ears, this is the product that exists to prevent that.
On top of the protection sits a surprisingly full feature set. There's a digital AM/FM tuner that presets and memorizes up to 10 AM and 10 FM stations, so you can jump between favorites without pulling out your phone. Bluetooth 5.4 handles music and calls, with a multifunction button for answering, rejecting, redialing and hanging up. An AUX input jack takes wired sources via the included cable. Power comes from a 1500 mAh rechargeable lithium battery charged over USB-C — up to 48 hours in Bluetooth mode and up to 125 hours in AUX mode. Comfort details matter here too: an adjustable padded headband, skin-friendly PU leather cushions with an anti-sweat design, snap-in ear cushions for easy replacement, and a carry bag.
Who should buy it: homeowners mowing lawns, woodworkers, shooters, and anyone in a loud shop or garage who wants entertainment and ear protection in one unit. Who should skip it: critical music listeners and gamers. The tuning targets high-fidelity playback for casual listening, but this is a hearing protector with speakers, not a studio headphone. It's also a single purple colorway, so if you want a neutral black look, that's a consideration.
• Best for sound quality and detail → Audio-Technica ATH-M20xBT. 40 mm drivers, a 5–32,000 Hz range and mid-range-focused tuning are aimed squarely at music listening.
• Best for hearing protection → PROHEAR 033. 31 dB SNR / NRR 25 dB with ANSI S3.19 certification is a real, measurable safety spec the Audio-Technica simply doesn't have.
• Best for battery life → Audio-Technica ATH-M20xBT. Up to 60 hours per charge versus up to 48 hours in Bluetooth mode on the PROHEAR — though the PROHEAR stretches to 125 hours in AUX mode.
• Best for a quick top-up → Audio-Technica ATH-M20xBT. A 10-minute charge yields about 3 hours of playback.
• Best for radio without a phone → PROHEAR 033. Built-in AM/FM with 10 presets per band; the Audio-Technica has no radio at all.
• Best for wired use → PROHEAR 033. AUX mode massively extends playtime (up to 125 hours) and works with the included cable; the Audio-Technica also goes wired via its detachable cable, but that's a fallback rather than a feature focus.
• Best for travel and portability → Audio-Technica ATH-M20xBT. It collapses for space-saving storage and uses an aluminum enclosure.
• Best for loud outdoor chores → PROHEAR 033. Passive noise cancellation plus certified attenuation is the whole point of the design.
In my opinion, the right pick comes down to one question: are you protecting your ears or enjoying your music? If it's music, gaming and calls, I'd buy the Audio-Technica ATH-M20xBT — the driver design, the wide frequency range, the 60-hour battery and the detachable cable make it the more versatile everyday headphone. If your listening happens on a mower, in a workshop or at a range, I'd buy the PROHEAR 033 without hesitation: certified 31 dB protection and a built-in radio are things the Audio-Technica cannot do, no matter how good it sounds. Check the current price on Amazon before you commit, and match the product to the job.
For pure listening, yes — in my opinion. The ATH-M20xBT uses 40 mm drivers tuned for mid-range definition and enhanced bass with a 5–32,000 Hz range. The PROHEAR is designed around hearing protection first, with HiFi speakers for casual playback.
Yes, that's their core function. They carry ANSI S3.19 certification with a 31 dB SNR and 25 dB NRR, which the manufacturer illustrates by noting that roughly 55 dB reaches your ears in an 80 dB environment. The Audio-Technica has no such rating.
The Audio-Technica ATH-M20xBT is rated up to 60 hours per charge, with a 10-minute quick charge giving about 3 hours. The PROHEAR 033 is rated up to 48 hours in Bluetooth mode but up to 125 hours in AUX mode, so it wins if you listen wired.
Both support it. The ATH-M20xBT includes a detachable 1.2 m cable with a gold-plated 3.5 mm plug, and the PROHEAR 033 has an AUX input jack with a cable included, which also extends its playtime considerably.
