The 1More Sonoflow offers active noise canceling which is great for noisy environments and air travel, and they have a long battery life, making them suitable for extended use without recharging. They are wireless with a detachable cable, have a foldable design for portability, and include app support for customization. However, if you prefer a more open soundstage, the Koss Porta Pro with its open-back design might suit you better, but it lacks a microphone, controls, app support, and active noise canceling. The Porta Pro is also lighter, but it's less versatile as it's wired and not suitable for exercise or noisy environments. Choose the Sonoflow for a feature-rich, modern set with ANC and wireless capabilities, consider the Porta Pro for a budget-friendly, classic design with a more natural sound experience. Give Feedback

"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."
"It’s clear to see why these have been such a popular choice amongst listeners for nearly four decades. It’s a charming pair of headphones that delivers a truly enjoyable listening experience and one that I think punches well above its weight."
