A reeling device which allows an electrical lead to be wound up without the need for slip-rings. The lead is partially wound around a spool and is electrically connected to contacts in a spindle, about which the spool rotates. A portion of the lead is sprung and is loaded as the spool rotates to pay out the lead. A ratchet and pawl mechanism is provided to lock the lead in its extended configuration. The ratchet and pawl mechanism can be relased so that the lead is retracted using the energy stored in the sprung portion of the lead. A pair of the reeling devices may be combined back-to-back to provide convenient storage for earpiece and plug leads for a headset. The reeling device may also be integrated into a portable electronic apparatus for storing earpiece or microphone leads.
