A:Answer Hi BLACK, WH1000XM3 truly allows you to connect two Bluetooth devices simultaneously with one device for music playback (e.g., a laptop connected via A2DP) and the other for calls (HFP/HSP: phone calls only) We hope you are enjoying our industry-leading noise-canceling headphones. With advanced noise canceling technology such as Adaptive Sound Control and the convenience of smart features including Quick Attention, Voice Assistant compatibility, and touch control, we designed these headphones so you can block out noise and experience next-level silence. If you haven’t already, download the Sony - Headphones Connect APP. This will give you the ability to use our ASC( Adaptive Sound Control) feature, so you can customize the noise canceling feature based on your activity. There is also an equalizer to fine-tune your music. ~Earl
