You have a few different speaker options with a Zune MP3 player. Zunes have a standard headphone jack and are Wi-Fi compatible. This opens several options for speakers, in addition to standalone speaker docks made specifically for Zunes.
Zune speaker docks are available at several price points and with varying functions. All docks should, at minimum, charge your Zune while it's plugged in. Depending on your needs, look for speaker docks with an alarm clock feature, remote and output capability to connect with a home entertainment system. Make sure the speaker dock you buy is compatible with your Zune model.
Any speakers that plug into a headphone jack can be used with a Zune. Speakers that plug in like headphones have been around for years. They're generally inexpensive and you can even repurpose an old pair of speakers from your computer in a pinch. Small headphone jack speakers are useful if you want speakers for traveling.
Lower-priced speakers tend to give lower-quality sound. While that's not always true, if you're a sound purist and you want the best speaker sound possible from your Zune, consider a dedicated speaker dock with an AV port. You'll be able to use the dock itself or plug into your larger home speakers.
Wirelessly sync your Zune player to any computer on your wireless network or your Xbox 360, and all your Zune's music will be available across your network. This means you can play your songs through the Xbox or any speakers available on the network. This may not be as convenient as small travel speakers or a standalone dock, but it does allow you to listen to your music without buying extra equipment.
