I bought at my own risk without reviews, read reviews only on Amazon. There are good reviews. There is nothing to compare with noise reduction, but it seems to me it could be better. Extinguishes decently, but some sounds are audible, including speech. They play well, the build quality is good, the kit includes a case, nozzles, adapters. When the battery runs out - these continue to play, maybe. in some models they stop playing. iPhone support on amazon is not declared. Declared in the headphones themselves and it is. The remote is located at a comfortable height, with volume and track change buttons. The location of the block is also very convenient, it is small and with a clip. Wherever you attach it: to a jeans pocket or an inside pocket of a jacket - the length just allows you to hold the phone in your hands. In general, a good model! and 4-ku for the fact that I have not used it much yet and there is nothing to compare noise reduction with. MB in six months I'll write off how, if I find jambs.
