How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want hearing protection that doubles as a passive music-listening earmuff with no batteries and no controls to fiddle with, choose Howard Leight Honeywell; if you need a compact powered preamp to boost a weak audio signal up to line level or drive a pair of headphones, choose ATNEDCVH Mini.
These two products sit in completely different corners of the audio world, so the "better" one depends entirely on the job in front of you. One is a piece of personal protective equipment that happens to play music. The other is a small desktop box that makes quiet signals loud enough to be useful. Let me break down what each one actually does, where it shines, and where it falls short — so you can stop comparing apples to oranges and just pick the right tool.
• Howard Leight Honeywell — biggest strength: Hearing protection and stereo music in a single passive earmuff, with a Noise Reduction Rating of 25 and no batteries, knobs, or switches to manage. Just plug in a 3.5 mm cable and go.
• Howard Leight Honeywell — biggest trade-off: It only works as a listening device when you plug something into the AUX jack, and there's no built-in volume control or amplification — the sound source does all the work.
• ATNEDCVH Mini — biggest strength: A genuine active preamp that applies a fixed 10x (20 dB) gain to weak signals, using a classic NE5532 dual op-amp and a noise-reduction circuit, with RCA, 3.5 mm, and headphone outputs.
• ATNEDCVH Mini — biggest trade-off: It needs external DC power (9–19V), it's not a power amplifier, and it can't drive passive speakers — it boosts line-level signals, not speaker loads.
• Who Howard Leight Honeywell is for: Anyone who wants to protect their ears on the job or at the range while still hearing music or audio.
• Who ATNEDCVH Mini is for: Tinkerers, vinyl fans, and hobbyists who need to lift a faint signal or add a headphone stage to a small setup.
The Howard Leight Sync Stereo Earmuff is first and foremost a safety product. Its core job is protecting your hearing, and it does that with patented Air Flow Control technology that reduces sound across all frequencies, landing at a Noise Reduction Rating of 25. That's a meaningful level of attenuation for workshop, range, or industrial settings. What sets it apart from a plain pair of muffs is that it also plays music — through a 3.5 mm AUX input jack and included cable — using an acoustical bass chamber that adds the low end most stereo earmuffs simply don't produce.
So who should buy it? If your priority is keeping your hearing safe while staying entertained or connected — a machinist who wants music, a shooter who wants audio between strings, a hobbyist in a loud garage — this is exactly the right tool. You should skip it if you're looking for a true audio component that shapes or amplifies sound. This earmuff doesn't boost anything; it's a passive hearing protector with a music passthrough. If you need gain, tone shaping, or headphone drive, it's the wrong device entirely.
ATNEDCVH Mini: Who It's For
The ATNEDCVH Mini is a small stereo audio preamplifier built around a specific, well-understood job: taking a weak signal and lifting it up to line level. It applies a fixed amplification of about 10 times, which is 20 dB, so quiet sources become usable ones. Inside, it uses the classic dual op-amp NE5532 paired with high-frequency electrolytic capacitors and a noise-reduction circuit, which the spec sheet describes as delivering effective gain without background noise. It's solid-state, stereo, and housed in a compact plastic enclosure measuring roughly 3.42 × 1.96 × 1.45 inches — small enough to tuck onto a desk or slip into a bag.
The connectivity is where this little box earns its keep. Inputs cover both RCA (left/right) and 3.5 mm, and the outputs do the same plus a dedicated headphone port. That headphone output can directly drive headphones, with a maximum supported impedance of 16 ohms — though the sheet notes you can't use the headphone port and the other outputs at the same time. A volume knob lets you adjust the level freely. Power comes from an external DC supply in the 9–19V range, with a static current draw of about 8 mA.
Side-by-Side: Which Should You Choose?
• Best for hearing protection → Howard Leight Honeywell. The NRR of 25 is the whole point of the product.
• Best for boosting a weak audio signal → ATNEDCVH Mini. A fixed 20 dB gain is its core function.
• Best for battery-free, control-free simplicity → Howard Leight Honeywell. No knobs, no switches, no batteries to replace.
• Best for connecting multiple audio devices → ATNEDCVH Mini. RCA plus 3.5 mm in and out, plus a headphone jack.
• Best for on-the-job comfort during long wear → Howard Leight Honeywell. Lightweight earcups and a padded headband are built for all-day use.
• Best for a compact desktop or portable audio setup → ATNEDCVH Mini. It's a small solid-state box you can move around easily.
• Best for turntable or instrument signal lifting → ATNEDCVH Mini. It's specifically designed to turn weak signals into line-level ones.
• Best for listening to music in a loud environment → Howard Leight Honeywell. It's the only one of the two that combines protection with playback.
In my opinion, the honest answer is that these aren't really competitors — they solve different problems, so the "winner" is whoever matches your task. If I had to pick for the majority of shoppers searching this comparison, I'd lean toward the Howard Leight Honeywell. It does something concrete and complete on its own: it protects your hearing at an NRR of 25 and lets you listen to music while doing it, with zero batteries or controls to manage. The ATNEDCVH Mini is the better choice only if your actual need is signal gain, headphone drive, or a flexible preamp stage in a small audio chain — and in that case it's genuinely excellent at that narrow job. Buy the one that matches the job, not the one that sounds more impressive on paper.
FAQ
They're not directly comparable — one is a hearing protector with music passthrough, the other is an audio preamp. The Howard Leight wins on protection and simplicity; the ATNEDCVH Mini wins on signal gain and connectivity. Pick based on your task.
No. The manufacturer states clearly that it is a preamp and cannot be used as a power amplifier to drive passive speakers. It outputs line-level and headphone signals, not speaker-level power.
No. It's a passive design with no batteries to replace and no power switches or volume knobs. You plug a 3.5 mm source into the AUX input and it plays through the earmuff.
The Howard Leight Honeywell, without question. The ATNEDCVH Mini offers no hearing protection at all, so it's not a substitute in any loud environment.
