How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of full size over ear headphones for everyday listening, choose Koss 183773; if you need a single-ear intercom headset with a boom mic for production or comms work, choose Generic Single Muff Male. These two share the "over ear" label and almost nothing else. One is built for music on the move. The other is a replacement part for a talkback system. Let's break down which one actually belongs in your bag.
• Koss 183773 biggest strength: A genuine stereo listening headphone — 18 Hz to 20 kHz frequency response, 100 ohm impedance, 101 dB sensitivity, closed leatherette cushions that seal and isolate, plus earcups that rotate and fold into a compact package.
• Koss 183773 biggest trade-off: It's wired only (3.5 mm jack) and it's a listening tool, not a communication tool — there's no microphone anywhere in the spec sheet.
• Generic Single Muff Male biggest strength: A single-ear design with a noise-cancelling boom microphone and a 5-pin male XLR connector, purpose-built to mate with RTS and Telex intercom systems.
• Generic Single Muff Male biggest trade-off: It's a mono, left-ear-only headset with a fixed boom mic, arrives in a plastic zipper bag rather than retail packaging, and the XLR connection won't plug into a normal phone or laptop.
• Who the Koss is for: Listeners, students, gamers and casual DJs who want full-size over-ear sound they can fold up and carry.
• Who the Generic is for: Audio techs, stage hands, and crew who need a working single-muff headset for an intercom beltpack.
The Koss 183773 UR29 is a full-size, collapsible, over-ear headphone. The spec sheet tells a clear story: dynamic drivers built with 1.4 mm Mylar elements to add rigidity and cut mechanical distortion, anisotropic ferrite magnets that keep volume up even on low-voltage portable gear, and oxygen-free copper voice coils for cleaner signal transmission. The frequency range runs 18 Hz to 20 kHz — full band, with the low end reaching well below what most portable headphones bother with.
The closed leatherette earcushions do double duty. They seal around the ear, which improves bass and blocks outside noise, and they keep sound from leaking out — a real benefit if you're listening in a dorm room or on a quiet train. The earcups rotate and fold inward, collapsing into a protective package that tucks into small spaces. There's also a volume control on the cord, so you're not reaching for your phone every time someone talks to you.
Who should buy it: Anyone who wants a wired full-size over-ear headphone for music, gaming, or casual mixing, and who values portability. The 100 ohm impedance and 101 dB sensitivity mean it plays loud off a phone or laptop without a dedicated amp. The lifetime warranty noted in the product details is a nice long-term signal for a headphone in this class.
Who should skip it: If you need a microphone for calls, streaming, or intercom work, this isn't it — there's no mic in the specs. And if you want wireless freedom, look elsewhere; the connectivity is wired via 3.5 mm, even though Bluetooth appears under wireless technology in the listing data.
The Generic Single Muff Male is a different animal entirely. This is a single-muff intercom headset with a 5-pin male XLR connector designed to mate with RTS and Telex COM systems, and it's positioned as a compatible replacement for RTS headsets. It ships in a plastic zipper bag after modification — the listing is upfront that the unit is new but not in original packaging. If you're the kind of buyer who needs the retail box, that matters; if you just need a working headset on a beltpack, it doesn't.
The design is left-ear only, with the mic boom fixed in place — it does not swing. The mic element is directional, and the label should face outward for best results. That's an important detail: get the orientation wrong and your transmit audio suffers. The ear cup is large, closed and leatherette, surrounding the ear for isolation, and it's described as lightweight and comfortable for indoor production and light-duty use. The dynamic element delivers sound at all volume levels, with a 20 Hz to 20 kHz frequency range, 120 ohm impedance, and 96 dB SPL/1 mW sensitivity. The noise-cancelling mic is the headline feature — it cuts background noise so your voice comes through clearly.
Who should buy it: Stage crew, production staff, and anyone maintaining an RTS or Telex intercom setup who needs a spare or replacement single-ear headset. The six feet of cable gives you room to move.
Who should skip it: Anyone who wants to listen to music. This is mono, left-ear-only, and the XLR plug won't fit a phone, tablet, or standard laptop jack. It's a communication tool, not a listening one.
Side-by-Side: Which Should You Choose?
• Best for intercom and production comms → Generic Single Muff Male. 5-pin XLR, noise-cancelling boom mic, RTS/Telex compatibility.
• Best for portability → Koss 183773. Earcups rotate and fold into a compact package; the Generic is a fixed single-muff with a rigid boom.
• Best for blocking outside noise → Tie. The Koss uses a closed leatherette seal and sound isolation; the Generic uses a closed leatherette cup for maximum isolation. Both isolate, in different ways.
• Best for plugging into a phone or laptop → Koss 183773. 3.5 mm jack, 100 ohm, 101 dB sensitivity — easy to drive from portable gear.
• Best for hands-free talking → Generic Single Muff Male. It's the only one of the two with a microphone.
• Best for low-frequency reach → Koss 183773. Its response starts at 18 Hz versus 20 Hz on the Generic — a small but real edge for bass-heavy material.
• Best for a one-ear-open work situation → Generic Single Muff Male. Single-muff design keeps one ear free to hear the room, which is exactly the point in live production.
In my opinion, the Koss 183773 is the one to buy for the overwhelming majority of shoppers, because "full size over ear" almost always means "I want to listen to something" — and the Koss is actually built for that, with stereo sound, a foldable frame, and a phone-friendly jack. I'd only pick the Generic Single Muff Male if you're specifically working with an RTS or Telex intercom system and need a replacement headset with a boom mic. It's a specialist tool, and it's good at its job — just not the job most people are shopping for.
FAQ
how should over ear headphones fit
how long do over ear headphones last
It depends heavily on build and use, but a few spec details hint at longevity. The Koss 183773 uses oxygen-free copper voice coils and a foldable earcup design, and the product details list a lifetime warranty — a strong signal about expected service life. The Generic Single Muff Male is described as light duty, so treat it as a working part rather than a decades-long investment.
are over ear headphones worth it
For listening, yes — the Koss 183773's full 18 Hz to 20 kHz range and closed-cushion isolation give you bass and quiet that earbuds struggle to match. For comms, the Generic Single Muff Male is worth it only if you actually run an RTS or Telex system, since its XLR plug and boom mic are useless outside that context.
are over ear headphones waterproof
Nothing in either spec sheet says waterproof, so treat both as splash-sensitive electronics. The Koss 183773 is a wired headphone with copper enclosures and leatherette pads; the Generic Single Muff Male is plastic with a dynamic element and a mic. Keep both away from rain and sweat-heavy workouts and they'll behave.
