Pros & cons
Koss Porta Pro
- ✓Rich, natural bass that's rare in open headphones at any price
- ✓Around 60g — light enough to forget you're wearing it
- ✓Non-fatiguing, forgiving tuning suited to long listening sessions
- ✓60-ohm/101 dB sensitivity runs easily from any phone or laptop
- ✓Koss limited lifetime warranty, and owners report decades of service
- ✓Folds into a small bundle with included soft case
- ✓Adjustable temple-pad pressure ('comfortZone') settings
- ✗Open design leaks sound both ways — unusable in quiet offices or transit
- ✗Soft, veiled treble; detail-heads will want the KSC75 or a neutral set instead
- ✗Fixed dual-entry cable can't be replaced when it fails
- ✗Folding mechanism pulls hair and the retro look isn't for everyone
