* Wireless headphones are going to let you sit in your living room at any hour and watch your giant TV or listen to your infinite music collection without disturbing anyone else.
* You can walk around without a cord pulling at you and can finally feel free.
* Cheaper than upgrading your speaker system.
CON
* The sound isn't as good.
* You have to charge the batteries or replace them.
* Possible interference and background noise as byproducts.
* Quality is similar to that of a radio broadcast.
* May interfere with phones or other wireless devices in the house.
* Only for in-home use. Too much headphone listening can lead to ear fatigue.
Technology
* Wireless headphones will either operate over a '''radio signal (RF)''' (over the 900 Mhz band) or with '''infra-red technology (IR)'''.
** Radio frequencies allow you to travel a couple hundred feet without losing your signal.
** Infra-red signals keep you within sight of the transmitter.
* '''Batteries''' can be rechargeable or replaceable.
** Rechargeable batteries have a stand in which the headphones sit. Try to keep them charged.
*** More cost-effective in the long run.
*** And better for the environment.
*** NiCd batteries are no good.
*** NiMh and Li-Ion are fine.
** Replaceable batteries work like any other kind of battery-driven technology.
* '''Dolby''' headphones provide the best surround sound.
* '''Auto-Tuning''' means your headphones will receive the clearest signal.
