JBL Reflect Flow Pro vs Bose QuietComfort Ultra

The JBL Reflect Flow Pro earbuds are engineered to elevate your workouts with secure, adjustable POWERFINS that ensure they stay comfortably in place no matter how intense your movement gets. Featuring Adaptive Noise Cancelling and Smart Ambient technology, you can seamlessly transition between blocking out the gym environment and staying aware of your surroundings during outdoor runs. Equipped with 68mm dynamic drivers delivering signature JBL bass, these earbuds keep you motivated through your toughest sessions. With a robust waterproof and dustproof design, sweat and rain will never slow you down, while the long-lasting battery ensures your soundtrack keeps playing from warmup to cooldown.

The Bose QuietComfort Ultra Headphones combine Bose's renowned noise cancellation with a new Immersive Audio mode that adds spatialization and head tracking to any content, creating a more three-dimensional listening experience for music and movies. An updated CustomTune sound calibration technology automatically adjusts audio and noise cancellation to the specific fit and shape of the wearer's ears each time the headphones are put on. With up to 24 hours of battery life (18 hours with Immersive Audio active) and a lightweight, plush design, they are built for all-day comfort during long listening or travel sessions.
