If you prioritize sound quality and have a dedicated amplifier, the AKG K712 Pro offers a very good listening experience, especially for music and TV, with an open design that enhances soundstage but offers poor noise isolation and no active noise cancelling. However, it's not suited for exercise or travel due to its size and lack of portability. The JBL Live 670NC, while offering lower overall sound quality, is better for calls and meetings, has active noise cancelling for travel, and is more convenient with wireless capabilities and optimized controls for smartphones. It also has a much longer battery life, making it suitable for extended use without charging. Consider your main use cases and whether the higher investment in AKG is justified for your listening preferences. Give Feedback

Headfonics

Michael | October 2013
"AKG has created a mini-masterpiece in my opinion. I enjoy this headphone a great deal and it will become my go-to reference headphone for the time being. She is slick, sexy, well-balanced, and crazy comfortable."
