The Koss Porta Pro, being less expensive, offers good overall sound and is very portable, making it suitable for an on-the-go lifestyle. If budget is a primary concern and you don't need wireless connectivity, the Koss Porta Pro could suffice. However, for better sound isolation and modern features, the Sennheiser HD 350BT would be a more comprehensive choice, especially for use during air travel or in noisy environments. Give Feedback

"Sennheiser nails just nearly everything about the Sennheiser HD 350BT headphones. Sound quality is excellent, and the high-quality Bluetooth codec support is a rarity at this price point. If you don’t care for high-tech features like automatic ear detection, you’ll be delighted with these portable headphones."
