The HifiMan Arya Stealth will provide you with a superior audio experience, particularly for music listening, with outstanding sound quality and soundstage. This is an excellent choice for critical listening in quiet environments, such as at home, but they're not suitable for exercise or travel due to their size and open design which doesn't isolate noise well. On the other hand, the Koss Porta Pro offers good sound quality at a budget-friendly price, and their portable design with foldability makes them a more convenient option for on-the-go use. However, they won't match the Arya's performance in sound fidelity and comfort, and similarly to the Arya, they are not intended for noise isolation or use in noisy settings. Give Feedback

"The Arya can easily be end-game headphones for 99% of consumers, satisfying most audio desires. Priced well above USD$1000, the Arya are obviously and gloriously not for the mass market consumer; they are designed and built by enthusiasts for enthusiasts – especially those who view their expenses on this level of gear as investments."
