Listening to your iPod doesn't have to be a solitary experience. The Logitech Wireless Music System (WMS) uses Bluetooth technology to wirelessly stream audio from your iPod--or any portable player with a headphone jack--to your home stereo. At $150, it's on the pricey side, and it suffers from an annoying design quirk, but its simple operation, excellent range, and impressive sound quality more than make up for these transgressions. Plus, unlike products that stream audio from your PC--such as the Roku SoundBridge and the Sonos Digital Music System, the WMS is immune to DRM restrictions. Anything your portable player can play is fair game for streaming.

XtremeMac is no stranger in iPod accessory land, but the company made its first foray into the tabletop audio arena with the Tango. (XtremeMac now also offers an iPod radio alarm clock, the Luna.) Indeed, the Tango looks a bit like a tabletop itself, a design that won't appeal to all users. However, we do have to give XtremeMac credit for coming up with a creative, music-centric product name. Of course, no one wants to tango to poor audio quality. Luckily, the Tango succeeds at offering decent music playback and plenty of bass. At $199.95, this speaker system ain't exactly cheap, so make sure you have all its faults and merits in mind before you go plunking down that credit card.

The Apple iPod is capable of a lot of functions, but it still lacks an FM radio, which makes for a significant ding on its report card. Luckily, there are now several add-ons that bring an FM tuner to the world's most popular MP3 player. One of those is Griffin's iFM, which has been updated for iPods with the newer-style dock connector. (The smart-jack version is also available.) The design of the in-line remote/radio is very similar, with a sexy new paint job in glossy black.

The Griffin Amplifi is a stylish, powerful iPod speaker system that's offered at an attractive price ($149). Compared with the heavyweights in the iPod speaker system market, the Amplifi lacks the refined sound of the Bose SoundDock (at twice the price), or the portability of the Altec Lansing iM600 or iM7. What it does deliver is loud, balanced, powerful sound, with a sleek design and an outstanding value.

That sneaky Apple: moving the headphone jack on the second-generation Nano fractionally closer to the right edge of the player. You probably didn't notice this slight difference from the first-gen player, but you can be certain accessories makers like OtterBox did. In turn, the company has tweaked its ruggedized case for the Nano to accompany the change. Now, 2G Nano owners can enjoy the same all-encompassing protection for their players. This kind of assurance will set you back $39.95--not too bad for this ultimate (if bulky) protection.

Given the iPod's growing use as a video device, it's no surprise that more people are looking for easy and convenient ways to get their iPod-based videos on the TV screen. Video cables and video-enabled docks are available, but most of them leave a lot to be desired in terms of remote control. Most, that is, except the Keyspan TuneView for iPod. Along with the updated DLO HomeDock Deluxe, the $180 (list price) TuneView dock/remote combo is among the better in-home accessories to date for remotely viewing videos and listening to music stored on your iPod. For some, it could even be a more affordable alternative to the $300 Apple TV.

One of the major drawbacks of most home iPod speaker systems is that the remote control that comes with the unit offers only limited control of your iPod. You stick the iPod in the speaker's dock and you can do little more than skip forward and back through tracks (and possibly playlists), raise and lower the volume, and pause and play audio. If you're lucky, the speaker has a display that's big enough for you to be able see what track is playing from more than a few feet away. Most don't, as they rely on the iPod's screen to display the relevant track and navigation info. Which brings us to George, the high-end iPod music system from start-up Chestnut Hill Sound. The George solves the interface problem in much the same way that Sonos does for media-streaming devices: it builds a remote into the system that essentially mirrors the display of the iPod. But the smart usability solution will cost you a pretty penny--the George retails for $500. That's a lot, to be sure, but--when you consider that it now includes the once optional external remote charger--it represents $100 savings off the George's original list price.

The iPod is the best thing to come along for exercise buffs since the cross-platform sneaker, so it makes sense that someone would put exercise instructions right on the device. Helmes Innovations' iWorkout ($16.99) provides you with helpful workout instructions for every muscle group and includes photos for those with video iPods.

To date, "wireless speakers" has been one of the great misnomers in consumer electronics. That's because many so-called wireless speaker systems actually introduce more wires into the equation--usually because those "wireless" systems require extra transmitters and receivers, both of which require their own power cables. And that's exactly why the Griffin Evolve is something of a revolutionary product: the $300 iPod speaker system includes two speakers that are completely free of cables. Despite a handful of drawbacks, most listeners looking for a semi-transportable audio system may well find the Evolve to be an ideal solution.

Ever since the first Bluetooth headset for cell phones came out, plenty of folks have been eager to see the day when Bluetooth audio made the transition to stereo sound, so you could ditch that wire connected to your iPod--or other portable music device--and feel, well, a bit more liberated. That finally happened last year, and now several new Bluetooth stereo headphones are trickling their way onto the market. The only problem is, most of them don't sound all that good, which is why we were pretty excited to hear that Etymotic, which is known for its high-performance wired earbuds, was getting into the wireless game.
