Enjoy music and control your headphones with the remote with the JBL Tour One M3 Smart TX Black. You receive a convenient audio transmitter, so you don't need an app on your phone. With the remote, you can choose which song you want to listen to, pick up when someone calls, and set a listening mode. For example, you can indicate if you're playing music, watching a movie, or gaming, and you'll hear the best sound. With the JBL Tour One M3 Blue, you can enjoy your favorite music without distractions. The headphones have 8 built-in microphones that scan and reduce ambient noise. You can barely hear your surroundings this way. Thanks to Hi-Res audio, you can play larger files than MP3 and hear more details in the music this way. Spotify doesn't support this technology yet, but streaming services like Tidal and Qobuz do support Hi-Res audio.
