Got this today for spoken videos -so not concerned about true fidelity of tunes. Works ok for music. But works very well for conference type situations. 1. Bluetooth pairs instantly for both ipad, MBA and iphone - works fine 25 feet away..no skips 2. 10 hour rechargeable batt so no plug ins 3. uses USB connection or Bluetooth 4. nice carrying case 5. $99 - I'm sure cheaper on web... Great road warrior tool.
