Once they were connected, I was able to examine the functionalities more closely. For example, the JVC HA-FW1000T has 'Qualcomm Adaptive Active Noise Cancellation'. This one does not disappoint at all. You will certainly be separated from your surroundings and you can enjoy your favorite music in peace. In the car, for example, I barely heard the other cars and the music from the radio that was playing. You can hear it, but if you really focus on your music, it's not noticeable.
This is not the only nice feature that JVC's in-ears have to offer. For example, they have a wear-detection sensor. When you take out one earpiece, the operation of the earpiece you are still wearing automatically changes to the most common operation; play/pause and louder/softer. Operation is no longer possible on the earpiece that you no longer wear. If you wear them both, the control options are more extensive.
Then the commands depend on each ear. When you tap 1x on the left side, you put the music on play or pause. With 2 taps you turn the music down. Tapping three times means that you will turn up the music and tapping four times means that you turn off the 'noise cancelling'. The right side then. When you tap 1x, the music will sound so soft that you can sense your surroundings. Tap two or three times to fast forward or rewind respectively.
Last but not least, the JVC HA-FW1000T in-ears have an IPX4 'rain proof rating'. So you should not be afraid of a few raindrops when you have the HA-FW1000T in your ears. In addition, thanks to the microphone, you can make phone calls and quickly ask the voice assistant. Finally, JVC has ensured that you are still well understood with your facemask mouth covering.
