Customer Reviews for Sony WF-1000XM4 Noise Cancelling Truly Wireless Earbuds
This buds are not able to remove noice when riding train, not any reduction from traffic, no home kitchen fan etc. The ear analyze has been executed and setup in phone was easy and quick. I am very disappointed. This is not worth using so i am selling second hand not used earbuds now. There are no effect on noice cancel, ambien or off modes. I can not hear the voice instructions when changing outside.
The memory foam buds were a nice touch for a great fit; a nice tug without too much pressure within the ears. In addition, I had zero problems with connectivity and setting it up to pair with my phone was straightforward.
Overall, my experience was superb and would highly recommend for both leisure or active sports related usage.
