About UVnano. I would like to believe that it is not metsin. At first glance, it seems that this is not a marketing ploy, but a really solved problem. Pros: Miniature and very pleasant to the touch case. Headphones do not fall out. neither from the case nor from the ears. There are a lot of cool features like adjusting the noise reduction or finding a lost earpiece (in the LG Tone Free app everything is described about the state of the headphones). Has some cons Didn't get it right with the sound. Couldn't switch to AAC. Therefore, the assessment of the sound is most likely not fair.
