If you want hi-res wired studio sound, marathon battery life and a headphones-plus-headset hybrid for work from home, choose OneOdio A70; if you need low-latency 2.4GHz wireless for PC and PS5 gaming with a mic in the box, choose MZYMI 2.4GHz.
Both are over-ear headphones that can connect to a computer. That's where the similarity ends. The A70 is built around a big 40mm dynamic driver, a 72-hour battery and dual 3.5mm/6.35mm jacks. The MZYMI is built around a 2.4GHz USB/Type-C dongle, Bluetooth 5.4 and a 20–25 hour battery tuned for gaming. If you're setting up a desk for work from home, that difference decides everything.
• OneOdio A70 biggest strength: 40mm neodymium drivers with a 20Hz–40KHz range, 72 hours of playback, and both 3.5mm and 6.35mm wired jacks — it works as a Bluetooth headset and as a wired studio monitor.
• OneOdio A70 biggest trade-off: It's a headphone first. There's an HD mic with noise reduction for calls, but nothing in the spec sheet about surround processing or a low-latency dongle.
• MZYMI 2.4GHz biggest strength: A 2.4GHz lossless connection with USB and Type-C, Bluetooth 5.4, lag under 30ms, 7.1Pro surround sound and environmental noise cancellation — genuinely built for PC and PS5.
• MZYMI 2.4GHz biggest trade-off: 20 hours on the headset (25 hours claimed for the carrying case), 2 hours to charge, and a plastic build with nylon mesh earcups rather than leather.
• Choose OneOdio A70 if: you want one pair for music, monitoring, and long work-from-home days without hunting for a charger.
• Choose MZYMI 2.4GHz if: you want a stable, low-lag wireless link to a PC or console and you care about surround sound and RGB more than bass extension.
The A70's core is its audio hardware. A 40mm dynamic driver with 32 ohm impedance, 110dB sensitivity and a 20Hz–40KHz frequency range is a serious spec for an over-ear wireless headphone — that upper figure goes well past the roughly 20KHz ceiling of human hearing, which is the kind of headroom DJ and studio gear is usually marketed on. In practice this tells me the A70 is tuned for bass-forward, dynamic stereo rather than a flat reference curve. If you mix, play guitar through an amp, or just want music to hit hard, that's the profile you want.
The wired side is where it separates from almost everything else in this class. You get a 3.5mm jack and a 6.35mm jack, so the same pair plugs straight into a laptop, an audio interface, a guitar amp or a mixer without an adapter. There's also an audio-sharing trick: connect the main headphones by Bluetooth or 3.5mm, then run the 6.35mm into the main pair and the 3.5mm into a second set of headphones so two people hear the same source. For a household where one person is gaming and another is watching, that's genuinely useful.
Comfort and battery are the other two pillars. The over-ear design uses memory cotton and protein leather, and the whole thing folds and rotates for storage — helpful if you move between a desk and a bag. The 72-hour battery figure is the standout number here. Paired with Bluetooth 5.3 and a 10-meter range, that's a headphone you can leave on a desk and forget to charge for a week. Item weight is 8.96 ounces, which is on the heavier side, but the padded over-ear fit is designed to offset that.
Who should buy it: remote workers who take a lot of calls, anyone who wants one pair that does Bluetooth and wired studio duty, and musicians or podcasters who need a 6.35mm connection. The built-in HD mic with noise reduction plus the 24-month warranty round out the work-from-home case. Who should skip it: if your priority is console gaming with surround sound and a sub-30ms wireless link, the A70's spec sheet doesn't address that need at all. It's also sound isolation, not active noise cancellation, so it won't silence a noisy room the way an ANC headset would.
The MZYMI is a gaming headset through and through, and the 2.4GHz radio is the reason. Unlike Bluetooth, a 2.4GHz dongle connection is designed to keep latency low — MZYMI quotes under 30ms — which is the difference between hearing a footstep when it happens and hearing it a beat late. The dongle is USB and Type-C, so it covers a desktop tower, a modern laptop, a PS5 and anything with a Type-C port. Bluetooth 5.4 is there as a second option for phones and tablets, with a 15-meter range, slightly better than the A70's 10 meters.
Inside, it's a 40mm dynamic driver again, but the tuning goal is different: 7.1Pro surround sound with "clear highs and deep lows" aimed at immersion rather than bass extension. Impedance is 50 ohm, higher than the A70's 32 ohm, which typically means it wants a bit more power to reach the same loudness — fine when you're plugged into a powered USB dongle, worth knowing if you ever run it passively. Environmental noise cancellation is on the spec sheet too, which is aimed at the mic side of calls rather than blocking out your room.
Battery is where the MZYMI makes its compromise. The headset runs about 20 hours and charges in 2 hours, with the bundled carrying case listed at 25 hours. That's a third of the A70's runtime, but the fast 2-hour top-up partly offsets it — you can charge it over a lunch break. Physical controls are button-based: volume, mute, call answer, track skipping and RGB light adjustment, plus an indicator light, charging port, 3.5mm jack and a dedicated microphone port. The 3.5mm jack means it can still go wired if the battery dies mid-session.
Comfort specs point the same direction: nylon mesh earcups and plush air protein over-ear cushions, chosen for breathability during long sessions rather than isolation. The build is plastic with a video-game theme and dynamic RGB lighting, and the carrying case measures 22 × 19 × 17 inches with a weight of 300g. It also ships with a cable. Warranty is listed at 30 (months, per the manufacturer's description).
Side-by-Side: Which Should You Choose?
• Best for battery life → OneOdio A70. 72 hours versus roughly 20, with a 2-hour charge on the MZYMI as the consolation.
• Best for PC and console gaming → MZYMI 2.4GHz. The 2.4GHz dongle, sub-30ms lag and 7.1Pro surround are exactly what the A70 doesn't offer.
• Best for studio, mixing and instruments → OneOdio A70. The 3.5mm and 6.35mm jacks plus 32 ohm impedance make it plug-and-play into amps and interfaces.
• Best for crystal clear calls → a split decision. The A70 has an HD mic with noise reduction; the MZYMI counters with environmental noise cancellation and on-ear mute. Both are viable for work from home.
• Best for long wear → MZYMI 2.4GHz on paper. Nylon mesh and air protein cushions are built for breathability; the A70 leans on memory cotton and protein leather for isolation instead.
• Best for sharing audio with someone next to you → OneOdio A70. The dual-jack sharing setup is unique to it.
• Best for a single wired fallback → tie. Both have a 3.5mm jack, so neither leaves you stranded when the battery runs out.
• Best for a low-fuss desk setup → OneOdio A70. Bluetooth 5.3, 10m range, 72 hours, done — no dongle to manage.
In my opinion, most people shopping for Bluetooth headphones for PC should buy the OneOdio A70. The 72-hour battery, the 3.5mm/6.35mm dual jacks, the 20Hz–40KHz driver range and the 24-month warranty make it the more versatile object — it covers music, calls, monitoring and work from home without you thinking about charging it. I'd only push you to the MZYMI 2.4GHz if gaming is the main event: the 2.4GHz dongle, under-30ms lag, 7.1Pro surround and RGB are things the A70 simply doesn't try to do. Pick based on whether your PC is a workstation or a battlestation.
FAQ
how to connect bluetooth headphones for pc
how to use bluetooth headphones for pc
Once paired, set the headphones as your default output in your sound settings, and pick them as the input device if you want to use the mic. The A70's HD mic has noise reduction for calls; the MZYMI adds environmental noise cancellation and an on-ear mute button. For gaming, the MZYMI's 2.4GHz mode is the better choice because of its sub-30ms latency.
how to bluetooth headphones to pc
Same process as any Bluetooth accessory — enable Bluetooth on the PC, hold the headphone's power/pairing button until the indicator flashes, then select the device from the list. If your desktop has no Bluetooth at all, the A70 can run wired through its 3.5mm jack, and the MZYMI can run through its 3.5mm jack or its USB/Type-C dongle.
how to pair bluetooth headphones pc
If pairing fails, remove the old entry from your PC's device list and start over with the headphones in pairing mode and close to the machine. Both sets use simple button controls rather than apps, so there's no software to install. Keep in mind the A70 tops out at 10 meters of range and the MZYMI at 15 meters before the signal gets shaky.
