The sound is not very, thick and bubbling, it was not possible to align to an acceptable equalizer. Often fall off the left earpiece, there is also some background noise that echoes each sound when watching video. Of the pros-only size and battery

the sound quality of these earphones is well above what you would expect at the $20-$25 price range. If you enjoy base, you will love these. And if it’s a little much, I found turning down the base in EQ worked great. And these headphones get loud, really loud — almost painful at the highest levels. I would describe the signature as somewhat v-shaped, with the base pushed quite a bit higher than the highs More details https://medium [dot] com/@vstolpner/tiso-i4-chi-fi-ear-thump-ae15e65fb81f

Headphones are just a bomb-mast hev, especially for such money. This is already the second order-for change while some are used the second on charging. Also ordered immediately for the wife "belenkie".
