But ...
the bass is significantly reduced. The material absorbs the sound and the ear seems not so clean seal, as the original. I suppose ambient noise significantly more true as before. I could compensate for some G35 equalizer on the Logitech, but it is changing in any case and by the increase in the bass speakers are more likely to Klipping if one is louder. At the end but a significant loss of sound performance. I have parallel back the old original Ordered. The here I use as long as the old ones are defective.
