While their immersive sound draws you in, the smart features of the JBL TOUR PRO+TWS headphones are there to support your busy lifestyle or relax you after. Take the Adaptive Noise Cancelling with Smart Ambient: enjoy a vivid sound performance in silence, if you need to focus, or with ambient sound, if you are walking in a street or want to chat with someone. Ready to play as they are out of the case, the earbuds can be used together for stereo audio or each on its own, allowing battery saving. Time for a conference call? No echo or ambient noise will disturb you, as the beamforming mics allow you to hear and be heard like you were there.
