Ok, Beyerdynamic headphones I own more than 26 years (DT990, DT901, DT880 new) but this is my first inEar of BD. Short - not so good: the transfer of impulse movement to the cable is transferred to the listener quite noisy, shielding against outside noise is not soooo good (my AKG have better shielded). well: and that makes up for everything - the sound !!! I had in-ear earphone belongs to 160 and hardly a sound as good as this - that in connection with the price of the base was to buy me these DTX 101 iE; namely here at Amazon, have thus again saving almost 10. My recommendation for all who value very spatial, crystal clear and deep, powerful sound !!!! Top 5 star.
