How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want classic wired on-ear sound with a collapsible, featherweight frame, choose Koss Porta Pro Black; if you need a self-contained AM/FM radio headphone that runs on AA batteries and works without a phone, choose UMUTOO A1.
• Koss Porta Pro Black — biggest strength: a genuinely portable wired design with a collapsible frame, ComfortZone temporal pads, and 15 Hz–25 kHz dynamic drivers with 16-ohm impedance.
• Koss Porta Pro Black — biggest trade-off: it's wired only (3.5 mm jack), has no noise control, and needs a source device to play anything.
• UMUTOO A1 — biggest strength: a built-in AM/FM digital radio with preset stations, LCD tuning, and a passive noise-cancelling over-ear fit powered by 2 AA batteries.
• UMUTOO A1 — biggest trade-off: it's bulkier and heavier (5.8 oz, about 165 g), needs batteries you supply, and it's tuned for radio listening rather than critical music.
• Who each pick is for: Koss Porta Pro Black suits listeners who want a compact wired headphone for phone, laptop, or player; UMUTOO A1 suits radio fans, walkers, mowers, and anyone who wants audio without pairing a device.
The Porta Pro Black is the definition of a portable wired headphone. It collapses down, ships with a soft carrying case, and the adjustable headband plus multi-pivoting ear plates let it fold flat into a bag or jacket pocket. The two ComfortZone temporal pads shift pressure so the ear plates sit balanced on your ears instead of clamping down — a small design detail that matters on long walks.
On the audio side, the numbers tell a coherent story: 30 mm dynamic drivers, 16-ohm impedance, and a 15 Hz–25 kHz frequency range. Low impedance means it's easy to drive straight from a phone, laptop, or portable player without extra gear. The on-ear shape keeps things light, and the plastic enclosure is built around decades of the same basic design language, which is why people still recognize it.
Buy it if you want a wired, lightweight, packable headphone for commuting, desk listening, or travel where you plug into a device anyway. Skip it if you need wireless freedom, active noise cancellation, or a built-in radio — the Porta Pro Black has none of those. It also does nothing on its own; without a 3.5 mm source, it's silent.
The UMUTOO A1 is a different animal entirely. It's an over-ear headphone with an AM/FM digital radio built into the cups, so the audio source lives inside the product. You get manual and auto search, preset stations, and an LCD display for tuning. The antenna plus a DSP filter chip are there to keep the signal stable with minimal static — the whole point is that you can walk, mow, cycle, or work without touching a phone.
Comfort is clearly a priority here too: wider memory foam ear muffs, an adjustable head strap, and a foldable design that shrinks to roughly palm size at about 165 g. The over-ear cups also provide passive noise cancellation, which helps mask surrounding sound — useful when you're outdoors or around equipment.
Power comes from 2 AA batteries (not included), so you can swap in fresh cells instead of hunting for a charging cable. There's also a 3.5 mm AUX jack and an included aux cable, so if radio reception is poor you can plug into a device and use it as a plain wired headphone.
Buy it if you want radio without a phone, value easy button-based controls, or want a gift that's friendly for older users and kids. Skip it if you mostly stream music from a phone and want the lightest possible packable headphone — the A1 is heavier and bulkier, and its 20 Hz–20,000 Hz, 32-ohm tuning is aimed at speech and general listening rather than audiophile detail.
• Best for built-in radio → UMUTOO A1. It's the only one of the two with AM/FM tuning, presets, and an LCD.
• Best for pure portability → Koss Porta Pro Black. Collapsible frame, soft case, and a very light on-ear build.
• Best for plug-and-play with a phone or laptop → Koss Porta Pro Black. 16-ohm impedance and a 3.5 mm jack make it easy to drive.
• Best for outdoor chores and hands-free listening → UMUTOO A1. AA batteries, passive noise cancellation, and no phone required.
• Best for noise isolation → UMUTOO A1. Over-ear memory foam cups with passive noise cancellation versus the Porta Pro's on-ear, no-noise-control design.
• Best for frequency range and detail → Koss Porta Pro Black. 15 Hz–25 kHz versus 20 Hz–20,000 Hz.
• Best for long-session comfort on the ears → Koss Porta Pro Black. ComfortZone pads and multi-pivoting plates are designed to redistribute pressure.
• Best for older users or kids → UMUTOO A1. Individual buttons and an LCD are simpler than navigating a paired device.
In my opinion, the Koss Porta Pro Black is the better pick for most people who already carry a phone or laptop, because it's lighter, easier to pack, and its 16-ohm, 15 Hz–25 kHz design is built for music first. I'd choose the UMUTOO A1 only if radio without a device is the actual goal — for mowing, walking, or a gift for someone who wants simple buttons and AA batteries. If price is your deciding factor, check the current price on Amazon for both before you commit, since the two sit in different tiers. Neither is a compromise if you match it to the job: one is a wired music headphone, the other is a pocket radio you wear.
FAQ
how to use external headphones on mac
how to connect mobile headphones
For the Koss Porta Pro Black, plug the 3.5 mm plug into your phone or a suitable adapter and playback routes through the headphone automatically. The UMUTOO A1 works either as a standalone AM/FM radio or as a wired headphone through its aux jack when you connect it to your phone.
how to connect c port headphones
Neither the Koss Porta Pro Black nor the UMUTOO A1 uses a USB-C plug — both rely on a standard 3.5 mm jack. To use either with a USB-C-only phone or laptop, you'll need a 3.5 mm-to-USB-C adapter, since the connection itself is analog.

The Koss Porta Pro Black collapses and comes with a soft carrying case, so fold it flat and slide it into a bag pocket. The UMUTOO A1 folds down to roughly palm size at about 165 g and stows easily in a bag or suitcase, though it's the bulkier of the two to pack.
