Review

I would consider the QCY H3 nearly acceptable for younger/casual ears that might need ANC for air travel purposes or even roadtrips. For budget over-ears ANC they provide some value and construction is above my expectations at a $40 price tag, and can easily be equivalent to what you find in name brand models costing 10 times as much. 

The overall sound ability is however substantially lower in quality as a result of the lower quality bluetooth codec in play, so there will not be any confusion as to why they cost $40. Set realistic expectations given the 4.5 star reviews and these might fulfill your goal, but otherwise they are not ear pleasing budget busters for me.
