Headquartered in Berlin/Germany, Amphony is a startup technology company specializing in the development of electronics products and technologies, in particular high-quality audio transmission. Amphony's new Model 1000 2.4GHz digital wireless headphone ($129) uses three Million Bits per Second, 64 times oversampled and uncompressed digital PCM data transmission for CD-quality sound over 200 ft. line of sight or 50 ft. through walls and ceilings. With a running time of 100 hours via two AA batteries, listening range can be expanded indefinitely with RangeBooster transmitters that communicate with the base station through a high-speed data port. The unit also features 1/2 rate FEC error correction to facilitate undistorted error-free transmission even in difficult conditions.

If you want pure listening pleasure in CD quality with the freedom of wireless headphones but without the noise, distortions and low dynamics of 900 MHz analog headphones, then take a look at the next generation of 2.4 GHz Digital Wireless Headphones from Amphony.

By transmitting the audio in a digital format, the 2.4 GHz Digital Wireless Headphones from Amphony allow you to listen to your favorite songs with the same audio quality that you are used to
from your corded headphones, except that you can now move around with absolute freedom.

Most importantly, since the 2.4 GHz Digital Wireless Headphones from Amphony transmit a data rate of over 3 Mbps (3 million bits per second) and since no audio compression is applied, you will experience true CD quality without audio degradation that you are used to from MP3 and other audio compression schemes.

Further, an error correction mechanism is employed which is capable of correcting transmission errors to guarantee superior error-free reception even under difficult conditions.

The 2.4 GHz Digital Wireless Headphones from Amphony are ready for the future by providing a
high-speed data port that allows you to connect peripherals such as RangeBooster transmitters

Hmm, sounds like a Sennheiser IS850, where the DAC is in the headphone itself... interesting...

I have a feeling that "64x oversampling" is kinda like a $50 amp that says "400 watts".

Can someone translate that commercialise/technical jargon into simple/head-fi english?

I have an Freesystems 'xdream', AKG Hearo 999, Sony MDR-DS8000, and all manner of virtual surround headphones and wireless products. It's my business as an A/V consultant to know what's going on. Although IR is more common, I prefer RF because I'm up and down, and move around the house frequently.

Praise due to Amphony for achieving a state-of-the-art digital 2.4 GHz modulation scheme. Unfortunately it is mated with a distinctly inferior quality headset! I'm going to modify the headset to put a jack in it so I can use my own headphones.

Yeah, the keyword you are looking for is "uncompressed". Yes, that's right, for once, all the information is being transmitted. So finally someone got that part right. Now, as to whether or not they got the rest of that right, remains to be seen...or heard...or auditioned...

they should make a reciever that you could clip to your belt or something that you could hook your own headphones into that would be wireless..

You foks must be aware that Headroom has had these for about a month now. I just bought one and have had it for about a week I wrote a first impressions review on it a week or so ago.

It's great for TV. For most forms of music, it's a bit too boomy. Sound quality in general is quite good.

The reception is fantastic. Great range (several rooms away and upstairs) before I lose the signal. The only interference is from the microwave oven, using similar frequencies.

Mine's a keeper.

It would be an ideal solution if Amphony came out with portable receiver with belt clip and a jack for my own headphones for better sound.

These have been out for a bit. I tried them last October:

http://www.head-fi.org/forums/showth...&threadid=3208

I posted impressions, but not to that thread, and I'm way too lazy to use the search function all THAT much

In brief, what's being sent is not the 44.1 digital bitstream from the CDP. The input is an analog signal that is converted to digital in the transmitter, and received and converted back to analog at the headphone. The transmission format was not clear.

The signal is extremely vulnerable to interference. When they say no microwave oven when listening, they mean it.

Sound is extremely veiled compared to the headphones I was using at the time (HD-560II, HD-580, HD-600). Not a contender for audiophile use by any stretch of the imagination. IMO strictly a convenience item.

I wouldn't call ign's articles "reviews" -- more like sales pitches. They give positive reviews to headphones most Head-Fi'ers wouldn't give to their least favorite person
