What a great find this was. I tried hearing music, it sounds great but, something is off. I?m middle aged, and as an RN my feet are almost ruined with all the walking I?ve done lo these many years. until my phone finished its play list and turned itself off and I was asleep. Took a second to assemble but would buy again. With the case beingso small and pocketable, theres always a safe place to put them. It has everything you need and one thing I did not think I needed but did. Perfect for rafting a river and such. Ill start by saying these are my first wireless earbuds so I have no previous comparison and Im writing this as of a week of owning them. The duel ear headphones do a great job of keeping home background noise at bay and make it easier to hear my students.
