Best budget earphone from Xiaomi.I'm using it for 1 year. I used many devices (Phones, personal computers, tablets, etc.). I can probably say that this headphone is the best price/performance headphone in the market. Build quality is solid and feels premium. The sound quality is perfect. Answers pretty well for custom equalizer settings. Bass sound is not like any headphone. It feels like an over-head. ( I'm generally using with my Galaxy S8.) In games, music, Youtube, etc. it blows me out. The only thing that I can talk about negatively is back of the headphone. Texture can get scratch easily. Bu this is not a problem at all.
