SOUND: Compared to: Sony SBH54. The 54th bottoms are "chocolate, warmer and tastier" with the same settings. But the wires from the block - to the ears and around the neck, I really can’t stand it anymore. I compared it on a branded promotional stand with all (!) monitors and wired "budget" Sony - the sound of the plugs is better in 70% of all listened to, even "non-budget" monitors. WEARING: Usually they don’t write, but the plugs should not be put into the ear, but screwed in - there must be a fit, otherwise there will be no bottoms. To do this, you need to carefully select silicones. Put the smallest one first. Then - the largest one, in order to immediately understand the difference in fit. Further, depending on the feeling, reduce the size. CONTROL. The control button on them, rather than the touch panels of other brands, is really cool. Wet, cold hands, gloves - no problem, always a clear understanding of "hit". SETTINGS: remove all settings in the phone to default. Download and install software from Sony. Everything else will be handled by their software. Otherwise, you will kill an hour to understand why what a disgusting sound or, as they often write in reviews: "a cool sound on a phone of some brand, but on some bad one." CHARGER. were sold almost empty. After full discharge, 5-7 minutes of charging provided music for 40 minutes. Sony SBH54 would have been fully charged in the same time.
