The SL-CT730 is a little over an inch thick and weighs a mere 4.8 ounces without the battery. You'll hardly notice it during your busy day, but you'll be glad you have it with you.Advanced D.sound technology is comprised of four components that work together to elevate your audio experience to the next level. A Digital Amplifier helps reduce distortion and also helps you achieve crystal-clear sound - even at higher volume levels. The S-XBS and Digital Audio Gain Control help to improve bass response at higher volume levels and MP3 Re-Master technology allows the listener to receive outstanding sound quality from compressed music files, such as MP3 and WMA.
Without H.Bass, headphones and compact speakers cannot reproduce some of the bass sound components that are included in music. H.Bass technology reproduces the harmonic series of bass components. This gives the listener the sensation of a fuller bass sound that cannot actually be reproduced with headphones and compact speakers.
You can achieve up to 150 hours1 of MP3 and up to 85 hours1 of CD-DA Playback with the supplied battery life expander. It lets you power the SL-CT730 with two Ni-MH rechargeable batteries and two AA alkaline batteries, for some amazing playback times.
The SL-CT730 is designed to reduce or eliminate CD skipping during most active uses. It even has a backup memory feature that helps provide further assurance of a skip-free listening experience.
MP3 is the most popular and widely used digital audio compression format available today. Since MP3 files are so small, you can burn a library of music onto CD-R/RWs2 from a compatible computer and play them back on your SL-CT730 Portable CD Player. And with ID3 Tagging, you can display the title, artist name and album name on the remote while the MP3 file is playing.
