I needed to replace my old headphones for listening to music from my smartphone while I am going to work. So I didn’t need anything of extra sound quality really, just a good price/quality ratio.And Philis was my choice because it’s a globally renowned brand. But their low-end headphones are not great. There are absolutely no high frequencies starting from 15 kHz.Anyways I am quite disappointed. They could put more effort even though it’s a budget headphone model.
