• Monoprice Monolith M1070 — biggest strength: a 106mm planar magnetic driver with a dual linear symmetry magnet array, tuned for accurate sound, low distortion, and flat, extended frequency response. Biggest trade-off: wired only, open-back (leaks sound both ways), and heavy at 580g — not a gym or commute headphone.
• Yealink BH74 — biggest strength: six-mic AI hybrid ANC with 32 hours of talk time and Bluetooth 5.3 multipoint, built for clear calls in noisy places. Biggest trade-off: on-ear, plastic-bodied, dynamic driver tuned "business-first" — it handles music well but isn't a reference-listening tool.
• Who the M1070 is for: listeners, hobbyist producers, and anyone chasing a flat, neutral signature who works at a desk.
• Who the BH74 is for: hybrid workers, call-center staff, and travelers who need their voice to come through cleanly.
• Quick call: flat frequency response → M1070. Wireless freedom and call clarity → BH74.
The M1070 is a planar magnetic, over-ear, open-back headphone. That combination is the whole story. Planar drivers are known for low distortion and even response across the band, and Monoprice pairs a 106mm planar driver with a dual linear symmetry magnet array specifically to deliver accurate sound with tight, clean bass and strong high-end extension. When people talk about flat frequency response headphones, this is the design philosophy they mean: don't boost the bass, don't spike the treble, just reproduce what's in the file.
Comfort and fit are handled thoughtfully. It weighs 580g, which is heavy by headphone standards, but the padded, adjustable headband spreads that load and the plush earpads are replaceable. Monoprice even ships two sets — memory foam lambskin and memory foam velour — so you can tune the feel to your preference. The 60-ohm impedance and wired 3.5mm connection mean you'll want a decent source; it's not the kind of headphone you casually toss in a bag.
Buy it if you want an honest, uncolored, wired headphone for focused listening at a desk and you care more about accuracy than convenience. Skip it if you need wireless, noise cancelling, a microphone, or something you can wear to the gym — the open-back design and wired connection rule all of that out.
Yealink BH74: Who It's For
The BH74 is a different animal entirely: a Bluetooth 5.3 wireless headset designed around voice. Its headline feature is a six-microphone AI noise-cancelling array combined with Yealink's 3.0 Sound Shield technology, which is engineered to block background noise — barking dogs, kids, keyboard clicks, café chatter — so only your voice reaches the other end. There are four adjustable ANC modes, and it carries Microsoft Teams certification over native Bluetooth, meaning you can join Teams without a dongle. It also plays nicely with Zoom, Cisco Jabber, Webex, and a long list of other UC platforms.
Battery is where it decisively beats any wired headphone: up to 32 hours of talk time, 65 hours of music playback, and 20 days of standby. A 1.5-hour charge fills it, and a five-minute top-up buys 45 minutes of talking. For anyone whose day is a string of calls, that's the difference between a tool and a toy.
It's also built for movement. Multipoint pairing lets it hold your phone and computer at once, and Bluetooth range reaches up to 50 meters — enough to walk the office mid-call. At just 152g with an adjustable headband, rotatable on-ear cushions, and auto-wear detection that pauses audio when you take it off, it's clearly designed to be worn all day. Adaptive EQ and a 20Hz–20kHz frequency response mean music sounds decent, though the dynamic driver is tuned "business-first."
Side-by-Side: Which Should You Choose?
• Best for flat frequency response → Monoprice Monolith M1070. The planar driver and dual linear symmetry magnet array are built for accuracy and low distortion.
• Best for call clarity → Yealink BH74. Six-mic AI hybrid ANC and Teams certification exist to make your voice the only thing heard.
• Best for battery life → Yealink BH74. 32 hours of talk time, 65 hours of music, 20 days standby.
• Best for soundstage and imaging → Monoprice Monolith M1070. The open-back grille creates an airy, spacious presentation.
• Best for all-day light wear → Yealink BH74. At 152g with float-on-air pressure distribution, it disappears on your head.
• Best for wired, noise-free reference listening → Monoprice Monolith M1070. 60-ohm impedance, 3.5mm jack, no Bluetooth compression.
• Best for hybrid work and travel → Yealink BH74. Bluetooth 5.3, multipoint, 50m range, charging dock included.
• Best for a quiet desk setup at home → Monoprice Monolith M1070. Open-back design suits private rooms, not shared or noisy ones.
If flat frequency response is genuinely your priority — and it should be if you're reading this — I'd buy the Monoprice Monolith M1070. In my opinion, a 106mm planar driver in an open-back housing is the more honest listening tool, and the included swappable earpads add real long-term value. The BH74 is the smarter purchase only if calls, wireless freedom, and battery life matter more to you than accuracy. For a workout, honestly, neither is ideal — the M1070 is wired and open-back, and the BH74 is on-ear rather than a sweat-proof sport design — so pick based on whether your day is about listening or talking.
FAQ
does frequency response matter in headphones
It can work well for gaming thanks to the open-back soundstage and precise imaging, which help with positional cues. It's not marketed as a gaming headset and has no boom mic, so you'd need a separate mic. As a wired option it's fine for a desk, but it's not the best gaming headset for workout use — it's heavy and open-back.
It handles music well for a work headset, with adaptive EQ and a 20Hz–20kHz range. That said, it's a dynamic driver tuned for voice, so it won't match the accuracy of a planar headphone. Think of music as a bonus, not the main event.
The Yealink BH74 — by a wide margin. It offers up to 32 hours of talk time, 65 hours of music playback, and 20 days of standby. The Monoprice Monolith M1070 is wired, so it has no battery at all.
If you're weighing these two, check the current price on Amazon before deciding, since that often settles the call. And if you specifically want the best headband headphones for workout or a wireless kids headset for workout, neither of these is the right category — but for flat, accurate sound at a desk, the M1070 is my pick.
