If audio quality for music is a top priority, you might lean towards the Sennheiser Momentum True Wireless 3 as they offer excellent sound, low latency perfect for gaming, and effective noise cancelling for undisturbed listening. However, their battery life is shorter than the JBL Live Flex 3. The JBLs are suitable for exercise with a sweatproof design and have a unique charging case with a touch display for controls, which might be appealing if you prefer tech-savviness and longer battery life, but they're not optimal for gaming or video due to poorer performance in those areas.
