If you prioritize sound quality and a more expansive soundstage for immersive music experiences, the AKG K712 Pro would be a better choice; these open-back headphones are especially comfortable for long listening sessions but are sizeable and not portable. However, their open design provides minimal noise isolation, which is not ideal for noisy environments. On the other hand, Koss Porta Pro, which is significantly less expensive and portable due to its foldable design, includes an in-line microphone making it suitable for calls and has decent sound quality. The on-ear form may be less comfortable over time, and similarly to the AKG, they have limited noise isolation due to the open-back design. Choose the AKG K712 Pro for home use and critical listening, or the Koss Porta Pro for a budget-friendly, versatile option with a microphone for calls. Give Feedback
