the only good thing of this product be the reasonable price , and the case go with it . the sound quality , as many people mention in the review , it very poor . you have to turn on the noise cancel function to hear a bearable sound , which be ridiculous . do not even mention the noise canceling , since it be not effective at all . I use it on two flight , and it only reduce about 20 % of the engine noise . it be way worse than the bose one , but consider the price , it make sense ... I do not recommend this product .
