How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired headphone with a volume dial right on the cord and a bass-forward, lightweight on-ear fit you can fold up and forget, choose Panasonic Headphones; if you need a USB-C over-ear headset with a built-in microphone, a share port for a second pair, and no adapter hassle on modern phones and laptops, choose Wuopzf USB C.
• Panasonic Headphones — biggest strength: an in-line volume controller plus a built-in XBS (Extra Bass System) port, in a 3.2-ounce foldable on-ear frame with dual 28mm drivers.
• Panasonic Headphones — biggest trade-off: it terminates in a standard 3.5mm plug, so you need an adapter for USB-C-only devices, and the spec sheet lists no microphone.
• Wuopzf USB C — biggest strength: a USB-C wired connection that covers iPhone 16, Samsung Galaxy, MacBook and iPad Pro without adapters, plus a built-in mic, in-line volume buttons and a 3.5mm share port.
• Wuopzf USB C — biggest trade-off: it's an over-ear design with no stated driver size or frequency range, and the spec sheet lists a 6-month warranty rather than a longer one.
• Who each pick is for: Panasonic for listeners who want cord-level volume control and punchy bass on a 3.5mm source; Wuopzf for people who make calls, game or share audio from USB-C gear.
The RP-HT227-K is built around one idea: give you control of the volume without reaching for your phone. The controller sits on the cord, so your hand finds it without looking. That sounds like a small thing until you're on a treadmill, walking a dog, or lying in bed at night — anywhere pulling out a device is annoying. Panasonic pairs that with an XBS port, a bass-boosting vent that magnifies low frequencies, and two 28mm dynamic drivers covering a 16 Hz to 22,000 Hz range at 24 ohm impedance. Low impedance like that means modest sources can drive it without straining.
The physical design is aimed at long, easy sessions. It's an on-ear headphone — cups rest on the ear rather than around it — and the construction is described as feather-light at 3.2 ounces with soft padded ear cups. On-ear cans often get uncomfortable after a couple of hours, but the weight here works in your favor, and the snug fit is meant to stay put when you move. Sound isolation is listed, which cuts some ambient noise but won't silence a plane cabin or a busy train the way active noise cancellation would.
Wuopzf USB C: Who It's For
Wuopzf takes the opposite approach. Instead of asking you to adapt, it plugs straight into USB-C. The compatibility list is the headline: iPhone 16, Samsung Galaxy phones, MacBook, iPad Pro and other USB-C laptops, with no dongle in the chain. If you've ever lost a 3.5mm-to-USB-C adapter on a trip, you understand why that matters. It's an over-ear headphone with fabric and silicone materials and soft memory foam cushions, plus an adjustable headband the listing describes as fitting all ages — a genuine advantage if you're buying for a teenager and an adult in the same house.
What separates it from a plain pair of wired cans is the control set. The in-line buttons handle volume, play/pause and answering or ending calls, and there's a built-in microphone for voice transmission. For anyone who takes meetings, plays games with voice chat, or just wants to answer a call without unplugging, that's the whole point. There's also a 3.5mm share port so a second headphone can plug into yours — handy for two people watching one movie on a laptop or passing a playlist back and forth.
Buy it if you live in USB-C, want a mic and inline controls in one cable, and like the idea of sharing audio. The foldable build makes it easy to toss in a backpack for travel, commuting, gaming or running. Skip it if your devices are 3.5mm-only, if you need documented driver size and frequency response before buying, or if you want the longest warranty you can get — this one is listed at 6 months, and it's rated for ages 6 and up rather than adult-only.
Side-by-Side: Which Should You Choose?
• Best for volume control on the cable → both, but differently. Panasonic uses a cord-mounted volume controller; Wuopzf uses in-line buttons that also handle play/pause and calls.
• Best for older phones, MP3 players and 3.5mm gear → Panasonic Headphones. It ships with a standard-sized plug adapter.
• Best for calls and voice chat → Wuopzf USB C. It has a built-in microphone; Panasonic's sheet lists none.
• Best for bass-forward, lightweight listening → Panasonic Headphones. The XBS port and 24 ohm impedance are aimed at easy, punchy playback.
• Best for sharing audio with a second person → Wuopzf USB C. The 3.5mm share port is the deciding feature.
• Best for small heads and mixed-age households → Wuopzf USB C. Adjustable headband, over-ear fit, listed for ages 6+.
• Best for travel packing → Panasonic Headphones. Foldable, 3.2 ounces, on-ear, and small enough to disappear into a carry-on.
• Best for spec transparency → Panasonic Headphones. Driver size, impedance and frequency range are all published.
In my opinion, the right pick comes down to your port, not your taste in sound. If your phone, tablet or laptop is USB-C and you ever talk on it — calls, meetings, game chat — I'd buy the Wuopzf USB C. The mic, the inline buttons and the share port do things the Panasonic simply isn't built to do, and skipping the adapter is worth real convenience.
If your listening is mostly music and audiobooks on a 3.5mm source, I'd take the Panasonic Headphones. The cord volume control is exactly what you want when your device is buried in a pocket, and the XBS bass and 3.2-ounce foldable frame suit long, casual sessions. Check the current price on Amazon for both before you commit — the numbers move, and this decision is close enough that price may settle it for you.
how to disable volume control on wired headphones
You can't switch off an in-line controller from the headphone itself in most cases — the controller is a physical component in the cable, not a software setting. Your practical options are to set volume on the source device and leave the dial or buttons alone, or use a different cable/headphone without an in-line controller. Both the Panasonic and the Wuopzf have control hardware built into their cables.
do earbuds have volume control
Many do, and so do many over-ear and on-ear models. Control can live in the cable (in-line buttons or a dial) or on the earcup itself. The Panasonic RP-HT227-K puts a volume controller on the cord, and the Wuopzf USB C uses in-line buttons for volume plus play/pause and call handling. Earbuds vary by model, so check the individual listing.
Not directly. It terminates in a 3.5mm jack, so a USB-C-only phone needs an adapter or dongle. Panasonic does include a standard-sized plug adapter, but that's for plug sizing, not for converting to USB-C. If your phone has no headphone jack, the Wuopzf USB C is the simpler match.
For calls and voice chat, the Wuopzf USB C has the edge because it includes a built-in microphone and in-line call controls. For pure listening, the Panasonic's XBS bass and 24 ohm impedance make it an easy, punchy option on a 3.5mm source. Pick based on whether you need a mic.
