text: These wireless, bluetooth headphones mostly deliver as advertised. They are very lightweight, the sound quality is on par for what I'd expect, the battery life gets close to 3 hours, and I really like the idea of carrying case, although it would be even better if the top of it stayed attached when you open them. The hardest part for me was understanding how to get both of them to play music simultaneously. Basically, you need to let one of these earphones (doesn't matter which one) pair to the other BEFORE pairing either with device. If you pair with your device first, both of them will show up and you end up having an either/or situation instead of both. So once they're paired with each other, only pair ONE of your earbuds to the phone and VOILA, you have music in both ears! I'll add that one other nice feature is having a separate charging cord that goes straight into the earbuds. With certain competition, the earbuds need their charging case or they can't charge, so kudos on the design here.
