Model 2000 2.4GHz Digital Wireless Headphones
Wireless headphones have been around for some time with results that often times fall short of user's expectations. My last pair of wireless headphones used 900MHz analog technology and most of the time worked fairly well . However, the technology sometimes resulted in occasional static with dropouts, range problems and limited dynamics. New wireless headphone technology such as the Model 2000 offered by Amphony Corporation, uses digital transmission along with sophisticated digital error correction that results in superior performance. The Model 2000 is a very capable product that transmits audio to the headphones using the 2.4 GHz band. Digital data is sent at a rate in excess of 3 Mbps (million bits per second) resulting in true CD sound quality with no audio compression. A noise-shaping filter incorporated in the headphones is used to remove quantization noise from the audible frequency band. The headphones have velour ear cushions and are comfortable to wear.
The headphones are fairly light even with the batteries installed. Each side of the headphones hold a single AA battery that locks securely into place. The level control is conveniently placed on the right side of the ear piece and adjustable with your thumb. The headphones had adequate power and played loud enough for my taste.
Sound quality was very good for a wireless system in my opinion. In fact, I haven't heard a better wireless system that I can recall. However, it still has serious competition with wired headphones such as the inexpensive Grado (SR-60 and SR-80) line. Taking the cost of the system into account, the H2000 delivers great performance for the money.
We disconnected our 2.4 GHz spread spectrum phone to prevent any interference with the performance of the H2000. Amphony recommends that you consider the environment in which you use the H2000 wireless system as it may encounter interference with such products as 2.4 GHz wireless phones and wireless Internet devices. While the system worked perfectly in our test setup, we did find limitations in the range of the H2000 headphone system. Shortly after moving from our main listening room where the transmitter was located, we did encounter some dropouts in the form of scratches. Much depended on the exact location and head orientation, but it was cartainly there. With this in mind, I would recommend keeping the distance between the transmitter and headphones to a minimum.
