The ANC is worthless. I don't think it works on any headphones and this is a person who uses earplugs regularly to block out up to 40 decibels of sound and probably has a bit of understanding around it. It's a marketing ploy and it involves deceit. I've had to redo this review because apparently I used a politically incorrect word so I'll be more effective with this one then... I think Jabra, like many people in the society, have pretty much given up. It's sad for the people that I continue to go on living life. Happily am I to continue my relationship with Amazon and their process which is a good one. Thanks Bezos. 😬 These headphones will quite good but not to the standard I was looking for so I realised I need to find ones without ANC and an emphasis on six mics. Otherwise I'm paying for features that not only don't work but take up part of the price. It's a very nice package that they provide and the app is decent but I'll only give it a two out of five.
