Unpacking gives a few reminders to try a few tips. I've never done that. But based on her repeated reminders, I decided to give it a try. The tops were not easy to put on, but once I put on the right pair the difference in fit became apparent. I'm glad I did. The product is covered by a one-year warranty. A quick start guide is all you need to set it up. If you need to change touch settings, register a product, or access other features, you must download the software. They work with my Samsung phone despite the "Made for iPhone/iPod" written on the box. See 3rd picture. They also work with my windows pc via bluetooth. See 4th photo. The sound quality is good. That's what I expected. Impressive is their adaptive, or they call it "intelligent" noise cancellation. This setting can be made in the app. After that, I wear them at home and on the go, and the headphones are smart enough to adjust to the level of ambient noise to always block out outside noise. A very good product so far.
