I could barely hear my surroundings and the sound is pure and clear. The package was missing all 5 hooks and also had no screws included either. It is a very natural sounding, open, listening experience. ------------------------Updating this - the gyro feature is a bit of a blessing and a curse. I must have about 10 pairs some of which I?ve had for over 7 years and I can honestly say they don?t make them like they used to. Wie gewohnte Qualität von Crocsfl. ???? The vendor provided a refund for the 1st pair but did not respond to my request for a refund for the 2nd pair. Alittle heavier than expected but very good quality with nice look Just by chance, I happened to look on the Logitech website, and I found that they sell both replacement tips and tip shields for the unit, which is quite nice.
