Unfortunately am not satisfied with the device - feel very bilig - Loads Although the Sony NWZE 444 without problems, but the generated charge and simultaneous connection of high-quality JBL-active speaker "On Tour" intolerable buzzing during operation while, chirping and rustling , Produces also when a little shake confidence-rattling. Did it just not be returned because it was still relatively low. Apparently you have to pay yet more for good quality in this area.
