The noise cancelling effect is excellent also, nothing gets in from the outside world. I never expected these to be so narrow. Only issue I have that prevents this from being a five star review are the green lights that come on while its charging. The story is amazing. The whole container is small. I drive them with two main sources, my Macbook Pro 16 and Oneplus 7 Pro. I wear an 8, ordered a 38, perfect fit! However, Im only giving it two stars because the headband is so delicate. Same price for the real stuff! I bought 3 new pairs of Teva flip flops from this seller and the ALL THE PAIRS are more broken down and worn over just these few months than the pair I purchased 5 years ago and wore constantly.
