LAS VEGAS--As their name suggests, SleepPhones (tagline: "pajamas for your ears") are designed for those who want to lie down while listening to music with a pair of headphones. Traditional headphones or earphones tend to get in the way or feel uncomfortable, especially when you rest on your side.
The current version of the SleepPhones, released in 2007, is essentially a pair of earphones hidden within a soft fleece headband. Most people will probably wear it like a hairband, though I can see the product being used as an eye mask for sleeping on a plane. Over the years, the material and speakers have been improved, but the cord remains. This limitation somehow doesn't give as much freedom in terms of head movement, and you have to keep the player close by.
Come April, however, the company will release a wireless Bluetooth version of the SleepPhones. It will retail at $79.95 (the cord version goes for $39.95). Its battery life is expected to range from 5 to 7 hours and the headset will automatically go into sleep mode once the music stops playing.
For those concerned about maintaining the SleepPhones, the speakers and battery can be removed from the fleece headband, which is washable.
