maybe ill provide an update in regards to that and the wear as i wear them over the winter. Some. These were for my wife who has small ear canals. Gigantic in my size 7 adult foot. The case has its own battery that retains a charge so they are charging anytime you put them in the case. Noise cancelling. Wer es basslastig mag, wird an diesen Köpfhörern seine Freude habe. Great purchase for the price! I thought the Omnium would be a great summer shoe. These fit good and they are excellent work shoe.
