HeadWize Forums - Headphone Reviews: "The MDR-DS3000 was first released in Japan in Sept. 2003 and according to Nikkei Business Magazine, has done so well that many retailers sold their entire stock before year's end. This is the new entry-level product in the Sony Wireless Surround headphones line that includes the DS5100 and the DS8000.
Here are the specs:
- Sony's own virtualizer technology produces 5.1 channel sound in stereo headphones, supported Dolby Digital and DTS decoding. The virtualizer uses a Logic 3D Processor (running at 125MIPS).
- The transmitter is digital infrared and can send to multiple headphones (MDR-IF3000).
- An 'intelligent' mute function cuts out noise when headphones are out of range
- Automatic power-saving shuts infrared signal output down if an audio signal is not received in 10 minutes.
- The MDR-IF3000 is an open headphone (30mm drivers) and runs on two batteries.
The DS3000 retails for about $189 US. Distribution is mainly in Japan, but the DS3000 is available at AudioCubes.com and Amazon.co.jp and jp.SonyStyle.com."
