Bests & Worsts Reviews from Amazon

I purchased these to listen to music or audio books on my walking commutes. They have never died on me, and my walk is 80 minutes - which is more than I can say for the last BT earbuds I had. I like the earbud receptacle/battery charger case. I not really impressed with the noise cancellation, but that's not a big deal for me (I've read that NC is primarily designed to cancel jet engine noise, and doesn't handle a wide variety of random frequencies well - what I experience walking home with traffic). These also stay in my ear better than the last set I had, which would fall out when I ran (it not fun trying to find the little buggers). They sound fine to me, but I'm not an audiophile and have some high frequency hearing, so I'm not a good judge of audio quality. I would purchase these again.
