I bought this pair, because the previous one had given up the ghost: there were virtually only the treble sound. No bass and little volume.
Simply EXCELLENT GOOD, no sound: When I then these headphones same as they were there auspobiert that a musical and klanvollen revelation came right.
Moreover, the comfort is right at the top. these headphones do not press uncomfortable and have a pleasant long cable.
For someone like me who has a, well ... high 'headphone wear', these headphones are exactly the right thing. Because the SENNHEISER MX170 in-ear headphones are price / performance technically the ne plus ultra - the best thing you can get in the price range.
Plus from a reputable manufacturer.
If this (by own fault) then give up the ghost, then I beselle me exactly this again.
