I gave it 4 stars instead of 5 for ONE reason. Noise isolation (not cancellation) is very dependent on using the right in ear bud attachment, it comes with plenty of options to choose from, so test a few in similar conditions to your usual set up. Helped keep my sweaty feet from sliding around in a strappy high heel. They are comfortable & well made! Seems all reasonably priced earbuds I have found are for smartphones only. Very comfortable and safe for the baby and also for the rider. Well worth the money! The Bose favor NC. I got this dock about two months ago and roughly a month after, it started changing the function on its own. Finally a spice organizer that works!
