WOW what a difference! These features in a wired set for under $50 is commendable! In other words, you wont know its a Bose unless you see the logo/label on top of the speaker. Night and day difference compared to the original pro rubber tips. I have 2 x 4s for feet (10) and depending on the style, sometimes need shoes in wide. I’m going to buy some more for my mom because her closet is wild. God. Similar devices are over $100. Highly recommend if youre looking for a cheap pair. Easy to startup and comes with batteries.
