won't charge / non-intuitive user instructions

despite following somewhat cryptic and non-intuitive instructions in booklet, headphones do not retain a charge, even after two full nights of connection to power source. advertised as have up to four hours of charge time, but closer reading of instruction booklet seems to indicate this is only obtained by reconnecting headphones to battery pack for up to three additional charges. This implies that each charge works for only about an hour. Headphones were purchased for athletic use (long runs and bike rides) and will not suit that purpose if battery life is that short in between re-chargings.
