and better suited for exercise due to being sweatproof and dustproof, with a comfortable fit and good noise isolation, ideal for outdoor environments. They also feature a unique smart charging case with an LED touch display. However, they have lower sound and build quality than the MW75-Neuro, which offer excellent sound, including for gaming and TV, as well as active noise cancelling and a high-quality microphone, making them ideal for a premium listening experience and calls. The MW75-Neuro also includes Neurable AI technology for focus tracking, which the JBL Live Flex 3 lacks.
