How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want reference-grade, wired accuracy and a foldable studio tool you can trust for critical listening, choose AKG Pro Audio K371; if you need wireless freedom, active noise cancelling and marathon battery life for long shifts, choose 1MORE SonoFlow-Pro Noise Cancelling. I'll frame this whole comparison around one very specific buyer: someone shopping for warehouse work, where noise, comfort over long hours and reliable connection all matter.
• AKG Pro Audio K371 — biggest strength: a wired, closed-back reference design with largest-in-class 50mm titanium-coated transducers, a 5 Hz–40 kHz range and 114 dB sensitivity, so it stays accurate and easy to drive from almost any source.
• AKG Pro Audio K371 — biggest trade-off: it's wired only, with no active noise cancelling and no Bluetooth, so it can't cut machinery noise electronically and tethers you to your device.
• 1MORE SonoFlow-Pro — biggest strength: QuietMax dual-feed active noise cancelling rated to reduce external noise by more than 45dB, plus LDAC hi-res Bluetooth 5.4 and up to 100 hours of playtime.
• 1MORE SonoFlow-Pro — biggest trade-off: it's a wireless consumer headphone with button-and-app controls, so its tuning and sound depend on Bluetooth codecs and ANC rather than a purely wired signal path.
• Who the AKG is for: mixers, editors, podcasters and anyone who wants neutral, wired monitoring and replaceable parts.
• Who the 1MORE is for: commuters, travelers and warehouse or factory workers who want to dampen loud environments and stay untethered all day.
The K371 is built around accuracy first. Its closed-back, oval over-ear design is engineered to match AKG's reference response curve, which is the brand's way of saying the tuning aims for neutral, balanced audio rather than a boosted, "fun" signature. For anyone doing critical listening — mixing, editing, podcasting or just wanting to hear a track the way it was intended — that neutrality is the whole point. The 50mm titanium-coated drivers with pure oxygen-free copper voice coils are the largest in this class, and the 5 Hz to 40 kHz frequency response plus 114 dB sensitivity means it doesn't need a fancy amp to sound full; a phone, laptop or interface can drive it.
Here's the honest trade-off for warehouse work: the K371 isolates passively, not actively. It muffles the world around your ears, but it won't cancel a forklift or a conveyor the way ANC does, and it's wired, so you're attached to whatever you're plugged into. If you want the best over-ear headphones for warehouse work in the sense of pure sound quality and durability, this is a strong pick — but if your priority is silencing a loud floor, it isn't the tool. Skip it if you need wireless, ANC, or app control.
1MORE SonoFlow-Pro Noise Cancelling: Who It's For
The SonoFlow-Pro is the opposite philosophy: convenience and noise management first. Its headline feature is QuietMax dual-feed active noise cancellation, which the brand rates at reducing external noise by more than 45dB — the kind of figure aimed squarely at subways, airports and busy streets, and by extension loud industrial spaces. Around that sits Bluetooth 5.4 with LDAC for hi-res wireless audio (roughly three times the data of standard Bluetooth), so you get a richer signal than plain SBC or AAC can carry, plus 40mm diamond-like drivers with a range up to 40 kHz.
Battery is where it really separates itself: up to 100 hours in standard mode and 65 hours with ANC on, with a 5-minute quick charge adding around 10 hours. For a warehouse shift worker who can't stop to charge, that's the difference between a tool that keeps up and one that doesn't. It's also built for stamina on your head: ultra-lightweight materials, soft protein leather cushions and an adjustable fit are explicitly aimed at long sessions, and the dual mics with an AI noise-reduction algorithm are tuned for clear calls in noisy places. There's a 3.5mm jack too, so you can go wired when you want.
The trade-offs are real. This is a Bluetooth-first headphone, so its sound quality is partly at the mercy of codec and connection, and its controls are button-and-app based rather than a studio-style wired path. The enclosure is faux leather rather than a pro-audio build, and while the tuning was handled by engineer Luca Bignardi for a natural balance, this is still a consumer ANC headphone, not a reference monitor. If you want a set that disappears into the background and quiets the room, this is it. If you want to hear exactly what a mix is doing, look at the AKG.
• Best for noise reduction in loud environments → 1MORE SonoFlow-Pro, with QuietMax ANC rated above 45dB versus the AKG's passive isolation only.
• Best for wired, reference-grade accuracy → AKG Pro Audio K371, tuned to a reference curve with 50mm drivers and a 5 Hz–40 kHz range.
• Best for battery life → 1MORE SonoFlow-Pro, at up to 100 hours standard and 65 with ANC, against a wired AKG that needs no battery at all.
• Best for wireless freedom and app control → 1MORE SonoFlow-Pro, via Bluetooth 5.4, LDAC and the companion app.
• Best for repairability and long-term durability → AKG Pro Audio K371, thanks to replaceable ear pads and a mini-XLR connector.
• Best for clear calls in a noisy space → 1MORE SonoFlow-Pro, with intelligent voice recognition and AI noise reduction.
• Best for packing and portability → AKG Pro Audio K371, which folds at the notched headband and comes with a pouch and multiple cables.
• Best for commuting and travel → 1MORE SonoFlow-Pro, where ANC and 100-hour battery earn their keep.
• Best for studio, mixing and podcasting → AKG Pro Audio K371, because neutral wired monitoring is exactly what that work demands.
If I were buying for warehouse work specifically, I'd pick the 1MORE SonoFlow-Pro. The reasoning is the job: a warehouse is loud, shifts are long, and you're moving — active noise cancelling rated above 45dB plus up to 100 hours of battery and no cable to snag is the combination that actually fits that environment. The AKG K371 is the better headphone for accuracy and for anyone doing critical listening, and I'd choose it without hesitation for mixing or editing. But for blocking out a noisy floor and staying untethered through a full shift, the SonoFlow-Pro is the one I'd put in my bag. Check the current price on Amazon before you commit, and weigh wired accuracy against wireless quiet.
For a loud warehouse, I'd lean 1MORE. Its QuietMax ANC reduces external noise by more than 45dB and it runs wirelessly for up to 100 hours, while the K371 relies on passive isolation and a cable.
Yes. There's a 3.5mm jack, so you can plug in when you want a cable, but the design is Bluetooth-first with ANC, LDAC and app-based controls.
They aim at different things. The K371 targets a neutral reference curve with 50mm drivers for accurate monitoring; the SonoFlow-Pro is tuned for a natural, balanced wireless listen with ANC and LDAC. For critical work, I'd take the K371.
Yes — the ear pads are replaceable and the cable connects via mini-XLR, which is a genuine advantage for longevity compared with a sealed wireless headphone.
