Sound That Stands the Test of Time
The Porta Pro Wireless delivers that iconic Koss sound signature - warm mids, punchy bass, and crisp highs. While it won't satisfy audiophile purists (the treble can feel compressed), it's perfect for rock, hip-hop, and podcasts. The open-back design means zero sound isolation - great for situational awareness, terrible for noisy commutes.

Battery Life That Impresses
20+ hours on a single charge isn't just marketing fluff. I left these in my bag for weeks, and they still had juice when I needed them. The USB-C charging is a welcome modern touch, though the wired mode feels like an afterthought (controls don't work when plugged in).

Love-Hate Comfort
The retro headband design is lightweight but divisive. It doesn't clamp hard, which means all-day comfort for some, but a loose fit for others. The stock ear pads are serviceable, but upgrading to Yaxi pads (a popular mod) transforms the experience - better comfort and slightly improved sound.

Built Like a Retro Toy
Don't expect premium materials at this price. The plastic feels cheap, and the metal headband, while sturdy, has sharp edges. The collapsible design is clever but feels fragile when adjusting. The included hard case isn't optional - it's necessary protection.

Who Should Buy These?
If you value battery life, situational awareness, and that distinctive Koss sound over noise cancellation or premium build quality, these deliver. At $100, they're pricey for what you get, but the retro charm and wireless convenience justify the cost for fans of the Porta Pro legacy.
