With the JBL Tour One M2, you can also enjoy your favorite music in a busy environment. The over-ear headphones has active noise canceling, a technology that reduces white noise and ambient noise. This way, you don't have to turn up the volume when you're on public transport. With the 4 built-in microphones, you can have clear phone calls. The Smart Talk function in the microphones also recognizes your voice. When you start a conversation with someone, this function turns down the volume of the music. As a result, you can easily have conversations while wearing the headphones. Connect the headphones to the My JBL Headphones app and adjust the sound settings to your liking via an equalizer. Thanks to the included airplane adapter, you can also connect the headphones with the entertainment system of an airplane. Note: JBL does include a charging cable, but no charger. Use your current accessories, or purchase them separately.
