I was also impressed by the noise cancelling. To my surprise, when we stick our key rings up there, you can feel the pull of the magnet with the key ring. The Jar these come in is Awesome ??I don?t have to transfer the beads to a different container. While I was satisfied with the sound and build quality (it is heavy and feels sturdy), I cannot recommend this BT speaker if you have any intention of using it to supplement the built-in speaker(s) in your PC/Android/OS device. Im a small D cup, if that makes sense. Si je devais lui reprocher quelque chose ce serait quil ny a pas dinterfaces de commandes (muet, volume) sur les écouteurs mais que le hub est sur le casque. I purchased these as a substitute and I am disappointed. I cant understand why anyone would give this a bad review. Mind you, I wear these as slippers - only indoors, usually between the bathroom and the bedroom when Im getting dressed for the day or getting ready for bed. I injured my knee so I was looking for a work shoe that was light.
