The Koss Porta Pro with mic offers an open-back design which generally provides a more natural and speaker-like listening experience but may let more ambient noise in, making them less ideal for noisy environments. They are more suited for at-home use or quiet areas. On the other hand, the Razer Hammerhead True Wireless earbuds offer a closed-back design which can isolate more ambient noise, making them a better option for commuting or air travel. They also have the advantage of being truly wireless, providing more freedom of movement without the hassle of cables. However, truly wireless earbuds can be more expensive and have a risk of being lost more easily than wired headphones like the Koss Porta Pro. If you prefer convenience during activities and better noise isolation, the Razer Hammerhead could be the better choice despite the higher price. 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."

Chris Welch | August 2019
"This latest set is more “Pro” than not in both looks and features: they offer active noise cancellation, a low-latency gaming mode, and have switched to a in-ear design with silicone tips. Just like many of the company’s laptops and gaming accessories, the 2021 Hammerhead True Wireless include Razer’s full Chroma RGB system. It makes for what Razer calls “the ultimate wireless earbud flex.”"
