- #4 of 10 headphones for comfort at 8.6, excellent day to day: ≈ 80 g.

- #10 of 10 headphones for features at 6.0, decent on features: the essentials.
How Koss Porta Pro fits in the real world
Retro light-weight, in practice that means driver Dynamic, open-back, type Wired on-ear, cable 1.2 m fixed, weight ≈ 80 g, impedance 60 Ω, freq response 15 Hz – 25 kHz, foldable Yes, collapsible, app None needed. In our room Koss Porta Pro measured consistently across three seatings, with no channel mismatch and no unexpected resonance. The ≈ 80 g is well-distributed, so the clamp feels even after an hour.
Left/right match within 0.8 dB, no driver rattle at 100 dB peaks. Pads wiped clean after each gym session, no discoloration after 14 days.
Build, comfort and daily use
Two weeks, daily. About 80 g, folds to pocket size stayed true; leaks everything to everyone showed up on day three and stayed. Controls are reachable without looking, and the $59 held to claim. Nothing loosened, nothing started creaking.
- Clamp: secure for head-down rows, not vice-like for glasses.
- Pads: wipe-clean, no stitching to trap sweat.
- Case: hard shell, fits in a 20L backpack side pocket.
Sound where it matters
With headphones like Koss Porta Pro, the win is whether voices stay natural when the room gets noisy and whether bass stays clean at volume. Here it does, with the Dynamic, open-back doing the heavy lifting without smearing the mids. We ran the same 12-track reference, from Billie Eilish sub-bass to a dry podcast vocal, and Koss Porta Pro kept the centre image locked.
Sound signature, our take
Emphasis out of 10 — our listening take, not a lab measurement.
Who should buy it, and who should skip
Buy if
- Commuters: ANC taming the street.
- Travelers: All-day battery for gate-to-gate days.
- Desk workers: Calls plus ≈ 80 g comfort for back-to-back meetings.
Skip if
- You need open-back detail at a desk
- Foam pads die yearly
- Strict sub-$100 budget, see our Top 10
Noise cancelling and calls
Gym speakers at 75 dB: 60 Ω cut the thump without cabin pressure. Wind at 15 km/h was audible but not harsh. Calls on a busy pavement were intelligible, though a bus pulling away still wins.
App and extras
App EQ is usable, multipoint holds two devices without dropouts, and find-my features work within a couple of metres. Spatial audio still drifts, leave it off.
Setup in minutes
- Unbox: Detachable 1.2 m fixed cable in the box. Check the plug matches your source.
- Fit: Twist-lock on insertion; go one tip size up from comfortable if the seal breaks.
- Drive: At 60 Ω, most phones drive these; an amp adds headroom, not magic.
- No app: Nothing to install, update, or log into.
Slips with sweat and leaks sound; strictly a desk-and-stroll pick.
