If price is a major concern and you're looking for a budget-friendly option, the Koss Porta Pro headphones would be more suitable as they are significantly less expensive. However, if you prioritize high-quality sound for music and are willing to invest more, the Moondrop Blessing 3 earbuds offer excellent overall sound quality. For those who need a built-in mic for calls or meetings, be aware that both models have poor mic quality. The Porta Pro's open-back design may provide a more expansive soundstage but will offer poor noise isolation, whereas the Blessing 3's closed design offers fair noise isolation. The Porta Pro is foldable and more suited for on-the-go use while the Blessing 3 is sweatproof, making it potentially more suitable for exercise. Neither model supports wireless connectivity, and if replaceable cables are important, only the Moondrop Blessing 3 has a detachable cable. Choose the Porta Pro for casual use and affordability or the Blessing 3 if sound quality and build are your top priorities. Give Feedback

"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."

"The Moondrop Blessing 3 has excellent imaging performance, especially for the price. Pair that with its neutral tonality with slight elevations towards both ends of the frequency response, and the Blessing 3 technically proficient set of IEMs that are also enjoyable to listen to every day."

About Moondrop
Moondrop is a Chinese brand of smart audio equipment, portable audio players, earbuds and headphones started in 2015.

Products such as the Blessing II, Chu and Kato are among the most popular offerings of the brand, more popular among those users that wish for good quality audio that won't break the bank. Besides audio, the brand also works in what they call the ACGN field (Animation, Comics, Games and Short Novels).
