Here's Pioneer's own advertising blurb:-

The SE-DRS3000C now leads Pioneer's line of wireless surround headphones. The 3D surround imaging is generated electronically from from a Dolby Headphone processor. The wireless medium is a digital stream over 2.4GHz RF carrier. To minimize dropouts from interference in the reception, the stream is simultaneously broadcast over 3 channels, so that the headphone's receiver can choose the cleanest signal. Pioneer calls this technology "3x3" transmission.
The open-back headphones utilize 50mm drivers for high quality cinematic imaging. Built into the enclosure are a power button and a volume control. The relatively low weight (350 gr) along with an adjustable headband and buckskin covered cushions offer long-wearing comfort. An internal Li-Ion battery powers the headphone receiver for up to 7 hours per 3-hour charge. An auto-shut-off function powers down the receiver if no signal is received. Additional headphones (model SE-DHP3000) can be purchased separately.
The vertically oriented transmitter also functions as a headphone stand and recharger. A 48-bit DSP is at the heart of the high performance digital engine that can decode several surround formats including Dolby Digital EX, DTS and AAC. A Dolby ProLogic II encoder converts 2-channel sources. The transmitter's operating status is displayed on the illuminated front panel. Located on the rear panel are two digital inputs (coax and optical) and 1 set of stereo analog inputs. The broadcast range is about 30m.
Available in Japan, starting May 2008.
Pioneer's SE-DRS3000C system combines a 2.4GHz wireless transmitter (TRE-D3000) with receiver headphones (SE-DHP3000) for untethered listening within a 30m range. Its "3x3 transmission system" sends data three times, while automatically choosing the best of three frequencies, to ensure against data loss from surrounding radiowave interference. To keep the sound as clean as the source, the transmitter applies no compression to the data. Supported bandwidth is 10Hz to 24kHz.
The unit's headphones incorporate large 50mm drivers and Dolby Headphone technology, with buckskin pads to cradle the ears. A 48-bit processing DSP recreates clear sound from formats including Dolby Digital, Dolby Digital Sound EX, Dolby ProLogic II, DTS, MPEG-2, AAC, and PCM.
The 'phones run on a lithium-ion battery; drop them onto the transmitter unit to recharge. The transmitter (not the headphones, as reported on many English-language gadget blogs) weighs 720g; the 'phones are 350g (20% lighter than Pioneer's previous wireless models).
Wireless headphones are of interest to anyone who wants to roam a bit while listening to high-quality sound. But Pioneer notes that AV fans with home theater setups are the category's key market, and promises a true movie theater-quality listening experience for buyers of the kit. Unless you always watch movies alone, however, you may need extra headphone units; Pioneer is glad to oblige for JPY26,250 per set.

The experience watching BDs with headphones is what i call , "a more intimate experience". Water splashes sounds more visceral and "visual", if you can call it that way. I'm watching National Treasure 2 now, and the escape from Cibola scene is almost too much in term of visual and aural, the weight of the water feels real, and convincing. Sure, i could get the same from the AVR+Speakers I'm using, but when you get only the sound reproduction from your headphones, and not any other external noises, the clarity and experience takes a whole new level altogether. The added bonus of not disturbing your neighbours while you enjoy your movies is nice too.
I'm still auditioning this thoroughly, I'll post my findings, pros and cons, strengths and weaknesses once I'm through. I already tested how far this headphone can go before losing signal, and the 2.4Ghz RF feed actually extends up to my downstairs kitchen! Listening to Ben Gates screaming "Haggis!" at the English bobbies at the Buckingham Palace while I'm making sandwiches has me laughing like hell!!
Your mileage may vary though, since I'm running my wireless network on another different band, Wireless "N" at 5Ghz, so no inteference from the headphone. I've switched it over to 2.4Ghz compatible mode on the Time Capsule, and there are times when the audio cuts off in split second, but immediately latches back on afterwards. But moving it back to Wifi "N", smooth sailing from there.
Audio quality wise, unparalleled! From the specs I've read, this headphones has none of those tacky rumble feature like some gaming-specific headphones I know of (Tritton AX360 anyone?), but crank up the bass on this, and hit Bass Assist to Level 2, and watch and feel this headphone trying to vibrate itself out of your ear sockets all on its own drivers power alone, no rumble crap necessary! Anti-bass-heads like me, who would prefer clarity over tacky bass/overdriving subwoofer-like effects, will appreciate this with the three different levels of Dolby Headphones levels, simulating from personalized audio room, to cinema theatre reproduction levels.
The headphone's set top box allows 2 optical/Toslink inputs and 1 coaxial, PLUS 1 optical/Toslink output, allowing optical/Toslink passthrough when the box is powered. This feature is a welcomed addition expecially if you are using it as a receiver of sorts to your dedicated AVR.
The headphone charges when you slip it into the slot, and ready for use when you take it off its charger slot. You can also replace the rechargable battery when the need comes. What's even more power-saving is the fact that only when you slip it onto your head, that the headphone is powered ON, the elastic headband detects when you are using the headphone and when you've slipped it off your big noggin'.
Volume is controlled at the righthand side of the headphone. It looks like a jogdial, but operates like a toggle, meaning you have to hold it in its possition to switch the volume up and vice versa. This is desirable because you dont end up with loose jogdials and having the volume going up and down crazily. This volume toggle also works as a headphone sync/ID identifier, since you can sync up to 3 other headphones to the same base.Which means movie night will never be the same for those who comes over your place(or mine in this case
) as others can enjoy and see(or hear , in this case) what I meant by a more "intimate movie experience".No more yelling and complaints from neighbours, or padding your movie theatre room so that sound doesnt leaks out and annoys the neighbours. 
That's about wraps it up for my impression on the Pioneer SE-DRS3000C.
Disclaimer: I understand the derision of mainstream audiophile/videophile on the issue of how "surround" these headphones are with their 2 cups/cans, but I urge an openminded mindset when it comes to this. I was once in this category, and went into the issue with an instant biasness against these section of supposedly "surround sound" offerings, and came out pleasantly surprised at how good they are. I would definitely suggest a tryout, or an audition before you dismiss these headphones.
