Overview

 |
CD-quality wireless
The Model 2500 utilizes advanced
uncompressed wireless audio transmission to achieve
true CD quality audio. Due to the low latency the wireless
signal is virtually free of any delay and the
headphone audio will be in perfect sync with video.
You'll forget that you are wearing wireless headphones. |

|
| |
 |
Multiple
audio inputs
The transmitter
provides an optical and one coaxial digital audio input. The audio
from these inputs is transmitted directly to the headphones without
any audio conversion or degradation. If digital audio is not available,
the transmitter also provides an adjustable analog audio input and
thus can connect to virtually any audio device. |

 |
Simple
setup
Setting up your Model
2500 is incredibly easy. No technical expertise
is required. Just connect the transmitter to your
audio equipment, switch on the headphones and listen to the music. The
volume can be adjusted directly at the headphones without having to
run back to your audio device. |
| |
|
|
| |
 |
Extendable
The Model 2500 is
ready for the future by providing a high-speed data output to connect
RangeBooster transmitters to extend the transmitter operating range so
that you can keep listening all over your house. |

"These are the best wireless headphones I have ever had. They are in a different
league."
Andrew D., USA |
|
|
|
"Your products are phenomenal."
Fred S., USA |
|
|
|
"The sound quality was excellent, even from analog source material. They were very comfortable. Frequency response
was clearly better than others, distortion was very low. Noise was totally absent, a clear difference from other brands...
So now I have great sound quality, no noise, and I can walk anywhere in a 50 foot radius with no reception problems at all.
Thank you for providing these headphones!"
Jim Z., USA |
|
|
"I have had your model 2500 headphones for sometime now and they are
great - the envy of my underlings!"
Jim H., USA |
|
|
"Thank you for a great sounding product!"
James O., USA |
|
|
"By the way, best headphones that I have ever had!"
Patricia A., USA |
|
|
"I have since bought a second (Audio Research) digi wireless and the
sound is not as good as the Amphony."
Robert B., USA |
|
|
"I am very pleased with the quality of the H2500 sound. I would
recommend the H2500 to any music fan because of the sound quality
(resulting from digital transmission) and convenience of the wireless
connection. I have a top end analogue headset but it suffers from
various shsshing effects as I move. The H2500 is immune from this."
Graham G., USA |
|
|
"Wonderful Product."
Geert K., USA |

"I am very satisfied with these phones, it's still early but I would
recommend them."
