How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want studio-style wired listening with a long coiled cord and a lifetime warranty, choose Koss 154336; if you need wireless Bluetooth freedom, a built-in mic, FM radio and memory-card playback, choose PODERIX PDBEAM.
• Koss 154336 — biggest strength: wired, studio-oriented design with 60-ohm dynamic drivers, oxygen-free copper voice coils, pivoting ear cups and a detachable 8-foot coiled cord. Biggest trade-off: no Bluetooth, no built-in mic, so you're tethered to whatever you plug into.
• PODERIX PDBEAM — biggest strength: Bluetooth 5.4 wireless freedom with 25 hours of playtime, a built-in mic, FM radio and mini SD card playback. Biggest trade-off: no wired jack at all, so once the battery is empty you're done listening.
• Who Koss 154336 is for: home listeners, studio and desk users, anyone who wants a passive-isolation over-ear with a long cord and no charging routine.
• Who PODERIX PDBEAM is for: travelers, commuters, gym and yoga users, and anyone who wants to leave their phone in a bag or pocket while the music plays.
• Quick gut check: Koss is the "plug in and forget it" choice. PODERIX is the "cut the cord and go" choice.
The Koss 154336 — sold as the R-80 — is a full-size, over-ear wired headphone built around a dynamic driver with neodymium iron boron magnet structures. The spec sheet puts its frequency response at 16 Hz to 22 kHz, sensitivity at 101 dB and impedance at 60 ohms. Those numbers describe a headphone that reaches noticeably lower into the bass than the PODERIX's 20 Hz floor, and the 60-ohm impedance means it's not a featherweight load — it's happiest plugged into a proper source rather than something ultra-feeble.
The design choices tell you it was made for long sessions in one place. The ear cushions are extra-large leatherette and closed-back, which seals around the ear, boosts bass perception and passively blocks some ambient noise. The ear cups pivot so they follow the shape of your head during extended wear, and the headband is adjustable for any head size. The cord is detachable, 8 feet long, coiled and single-entry — long enough to walk from a desk to a shelf without yanking the plug out of your ears. You also get both 1/8-inch and 1/4-inch stereo plugs, which is the classic home-and-portable pairing: 1/4-inch for a receiver or amp, 1/8-inch for a laptop or phone.
Who should buy it? In my opinion, this is for someone who listens at a desk, in a home setup, or in a studio-ish context and wants one pair that stays put. It's also a good fit if you hate charging things — there's no battery here at all. The lifetime warranty is worth flagging too, because it signals the manufacturer expects this pair to be a long-term companion rather than a disposable gadget.
Who should skip it? Anyone who wants to move around the house, work out, or take calls wirelessly. There's no Bluetooth, no mic, and no battery. If your phone has no headphone jack and you don't own an adapter, this isn't the pick for you either.
The PODERIX PDBEAM is the opposite philosophy. It's a wireless, foldable, over-ear Bluetooth headphone running Bluetooth 5.4 with a 10-meter range, and it's built around convenience rather than a desk. The headline number is 25 hours of playtime and up to 120 hours of standby on a single charge — enough that most people will charge it once a week, not once a day.
The feature list is unusually broad for a wireless over-ear. It has a built-in microphone for calls and voice control, push-button volume controls, a built-in FM radio mode, and mini SD card playback. That last one matters more than it looks: you can load music onto a card and listen without pairing a phone at all, which is genuinely useful if you want to leave your phone alone while you work out or wind down. The FM mode is a nice fallback when you want something playing without touching your library.
Comfort and fit are clearly the design priority. It weighs 7.2 ounces — lighter than the Koss's 9.6 ounces — and the headband adjusts for all head sizes. The ear cushions are described as soft memory protein, which suggests a plush feel over long stretches. Passive noise isolation is there, aimed at flights, office work and home listening rather than active cancellation. The enclosure is plastic with a fabric carrying case, and the finish is an apricot / white-cream tone with a grey case, which is a distinctly softer look than a plain black studio headphone.
Who should buy it? Travelers, commuters, gym and yoga users, and anyone who wants to move between rooms without unplugging. It's also the better pick if you take calls, since the Koss has no microphone. And if you like the idea of listening from a memory card instead of your phone, nothing in the Koss's spec sheet offers that.
Side-by-Side: Which Should You Choose?

• Best for wired, zero-charging use → Koss 154336 (no battery, detachable 8-foot coiled cord).
• Best for battery life → PODERIX PDBEAM (up to 25 hours playtime, 120 hours standby).
• Best for low-end reach on paper → Koss 154336 (16 Hz–22 kHz versus 20 Hz–20 kHz).
• Best for calls and voice control → PODERIX PDBEAM (built-in mic, push-button and voice controls).
• Best for studio or desk setups → Koss 154336 (60-ohm impedance, pivoting cups, 1/4-inch and 1/8-inch plugs).

• Best for long-term ownership peace of mind → Koss 154336 (lifetime warranty).
If I had to pick one for myself, I'd take the PODERIX PDBEAM — but only because my listening happens on the move, and I value the mic, the 25-hour battery and the memory-card playback more than I value a cord. If your listening happens at a desk or in a home setup, I'd flip that and recommend the Koss 154336 instead: the lower 16 Hz extension, the pivoting cups, the detachable 8-foot cord and the lifetime warranty make it the more durable, more "set it up once" choice. These aren't really competitors so much as two answers to two different questions. Buy the one that matches where you actually listen.
No. The Koss 154336 is a wired headphone with a detachable 8-foot single-entry coiled cord and a 3.5 mm plug, plus a 1/4-inch plug for home gear. There's no Bluetooth and no battery, so it never needs charging.
No. The PDBEAM connects over Bluetooth 5.4 only — there's no headphone jack listed. If the battery runs out, you'll need to charge it before listening again.
The PODERIX PDBEAM, by definition — it's the only one with a battery. It's rated for up to 25 hours of playtime and up to 120 hours of standby. The Koss 154336 has no battery at all, which some people prefer.
In my opinion, the PODERIX PDBEAM. It's lighter at 7.2 ounces, folds for storage, comes with a fabric carrying case, and has no cord to snag. The Koss's 8-foot coiled cable is the opposite of gym-friendly.
