Speaker Docks, knives, and headphones

Meh... I am mad... Really mad...
All these headphones... do you think you can find some... that have a lithium ion battery, a lightning port, and something that goes really loud... I'd love that for a headset... (also I think you may sell more rechargeable batteries than speaker docks... but no one complains about that either.) You know... Personal speaker dock that goes on my head...

Thanks!
