At first I thought it was hype. And I DID research other brands. But after the first 2 full charges, I got 8 1/2 of quality music with my Nokia 5700. I still had more charge time on these headphones for music. These are NOT heavy at all. I don't even mind when people try NOT to stare at me in public. Sound quality with phone calls is good. For once nobody complained about background noise. Amazon, your prices and service are second to none. Thank you.One happy New yorker.....Buy THESE Mr. Brown!
