In the eternal quest for sleep in airline economy seats, the Zami pillow might get you some Zs.

The multicell pillow has a two-tiered center cell that forms the heart of the pillow, with smaller cells on either side. Each cell has a blow-up valve, so all can be inflated or just one or two. The end cells have a velvety finish that is soft on the face. Fully inflated, the pillow is slightly more than 13 inches tall, meaning that it's possible to place it on the lap and lean onto it for a comfortable snooze, especially on long flights.

It might take a little practice to get the balance right, but it does work. Dropping the airline tray table down, and wedging the pillow against it and the back of the seat in front can afford an even more comfortable snooze. Deflated, the encased pillow is no thicker than a couple major magazines, so it's no space hog in the carry-on. The pillow invites experimentation to find a comfortable posture. $19.95, plus $8.50 shipping, www.thezami.com

Floating in the ocean with music in your ears. Here is a waterproof MP3 player that doesn't need earphones. The SwiMP3 rests on your cheeks while you swim, using bone-conduction technology to transmit music vibrations to your ear, so you hear music in fine detail. Swimming to your favorite tunes makes your laps in the hotel indoor pool more enjoyable.

How it works: Your goggles hold the SwiMP3 in place, as it plays about 60 tunes you have selected and transferred to the device from your Mac or PC. While earphones vibrate air to turn digital files into sound, the SwiMP3 vibrates the fluid in your inner ear to transmit sound.

The good: Even underwater, music on the SwiMP3 sounds deeper and richer than when listening through waterproof earphones to a regular MP3 player that's encased in a waterproof case. And the one-piece device isn't as bulky as a setup that requires earphones, an MP3 player, a waterproof case and an armband — or another method of keeping the MP3 player in place.

The bad: You have to wear goggles. There's no other way to hold the SwiMP3 securely. $150, www.swimp3.com.
