Package from Amazon arrived today: Anker Soundcore Space Q45 over-the-ear headphones. The device has a 50-hour battery on board and can connect to an audio source via 3.5mm stereo cable or Bluetooth. It can be paired with two different Bluetooth devices and switch between them by pressing the power button twice quickly. Charging is via USB-C cable and the associated mobile app can be used to set up a personalised sound profile based on emitted sounds, some of which are inaudible to your ears. There are 5 different levels of Active Noise Cancellation as well. They are comfortable to wear and sound really great. Test recordings using the microphone sounds quite good, too. Amazon has a special 25% Prime Members' discount which was nice, too.
