Do you have music lovers on your Christmas list this year? They probably already have Apple iPods or other MP3 players.

So give them gifts that help them get more out of their players. I've got five great ideas to get you started:

HEADPHONES

Music players come with headphones, but most are mediocre. Music lovers want to hear the music without extra noise, that's why they need noise-isolating headphones.

Noise-isolating headphones fit snugly inside the ear and seal out outside sound. Manufacturers say these headphones block 90 percent of outside noise. This means you hear more at lower volumes.

Etymotic (www.etymotic.com), Shure (www.shure.com) and Ultimate Ears' (www.ultimateears.com) noise-isolating headphones provide a richer, wider sound range. Expect to pay at least $100. Don't buy noise-canceling headphones. They produce a noise that cancels out outside noise.

CAR KITS

Your music lover will want to listen to the player in the car. Unfortunately, music players are difficult to connect to car CD players. But there are a few options.

FM modulators transmit music from the player to the car's FM radio. Wireless ones connect easily. Wired ones connect directly to the stereo, requiring more work.

Belkin (www.belkin.com), Griffin (www.griffintechnology.com) and Scosche (www.scosche.com) make modulators. Prices start around $30.

You'll also find kits that connect to the stereo's line-in jack. Some allow you to control the player via the car's stereo. Others include special displays or controls. Expect to pay upward of $150.

Make sure the kit is compatible with the car. Monster (www.monstercable.com), Harman Kardon (www.harmankardon.com), and Dice Electronics (www.diceelectronics.com) make car kits.

FOR RUNNERS

The Nike + iPod Sport Kit from Apple is the ideal gift for music lovers who run. It requires an iPod Nano and special Nike running shoes.

A sensor slips inside the running shoe. The sensor measures time and distance, plus it calculates the number of calories burned. Information is transmitted wirelessly to the iPod. $30.

CASES

A case is always a welcome accessory for any music player. Cases help protect players from scratches and falls. And they can add a little extra personality.

You'll find cases online or at your local electronics store. Make sure you're buying one for the correct make and model of player.

GIFT CARDS

For iPods, the iTunes Music Store is the only game in town. Likewise, Microsoft's Zune is only guaranteed to work with Zune Marketplace.

For other music players, things become more complicated. Real Rhapsody, Urge, Yahoo Music and Napster offer gift cards, but they don't work on all players.
