The more I use these the better they seem to sound. The trick is to have good quality earbuds and find your right fit to suit your sound. The high range is very clear and crisp, the midrange is to much but that can be adjusted with you device’s equalizer and as for the bass well it’s ok but not deep enough for some of my reggae tracks but is ok on certain dance records to get more bass you need good quality buds and the right ear adjustments. My overall opinion is for the fifty pounds paid these are well worth the money.
Very good headphones for a good price. The sound is clear and well balanced. I'm using them with an amplifier (Fiio FQ1222).
