The Koss Porta Pro headphones are a budget-friendly choice known for their impressive sound quality for the price, but they lack modern features like a built-in microphone and wireless connectivity, making them less versatile. They're on-ear with an open back which offers a more expansive soundstage but they don't isolate noise well, so they're not ideal for noisy environments. In contrast, the Sennheiser 450BT costs more, but they provide a closed-back design for better noise isolation and active noise cancelling, which enhances listening in noisy settings, such as air travel. These headphones also have a built-in microphone and support wireless connectivity with low latency, suitable for gaming and watching TV. For long battery life and the convenience of features like an app equalizer, the Sennheiser may warrant the higher price. However, if cost and sound for music listening are your primary concerns, you might prefer the Koss Porta Pro. Give Feedback

"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."
