Very good if you take the trouble to choose the tip (the biflanges for me) and push them into the ear which is not easy given their shape not very suitable, turn them until they find their place, cable upwards. This is why it is better to use them than listening rested action because the sweat will slip and it will readjust. Otherwise one can read comments that murderers are not justified. At that price, even 2 or 3 times the amount, hard to beat. In any case much better than the Sennheiser CX300 (or Creative Ep630, it seems identical) that are very oriented towards the low end with mid / lower treble, less detailed and indented. The same would be beaten and more ergonomic (the PL50?)
