If noise isolation and active noise cancelling are high priorities for you, especially for use in noisy environments or air travel, the JBL Live 770NC headphones would be the better choice. They are also wireless with a long battery life, have a built-in microphone, and are optimized for both Android and Apple devices, making them versatile. However, they are on the heavier side and have a higher cost. On the other hand, if you are looking for a budget-friendly option primarily for listening to music, the Koss KSC75 headphones provide very good sound quality at a much lower price, but lack wireless capabilities, active noise cancelling, and a built-in microphone. They are lightweight and may be comfortable for extended wear, but are less suitable for exercise and less durable overall. Give Feedback

"Let’s not insult the KSC75 by saying that it’s simply good for the price… because it’s far more than that. It basically has a monopoly at its asking price, and could still give modern budget headphones a run for their money 15 years after its release. The KSC75 is the world’s best not-headphone."
