The AKG K712 Pro offers very good sound quality with a very good soundstage, making them well-suited for listening to music and watching TV or videos. Being over-ear, open-back headphones, they are comfortable for long sessions but may not be ideal for noisy environments as they don't isolate noise well. They need a dedicated amplifier for the best experience and are not portable or suitable for exercise. In contrast, the JBL Live Flex 3 earbuds are wireless with very good portability and are better for use during exercise, with features like sweatproof and dustproof certification. They are less expensive and provide good sound quality but are not optimal for calls and meetings or gaming due to poorer soundstage. The Smart Charging Case with an LED touch display offers convenient controls, and the earbuds support LDAC for high-quality audio over Bluetooth. If you often travel or need versatility, the JBLs are a solid choice, but for home use focused on high-fidelity listening, the AKGs are superior. Give Feedback

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."
