5.8 GHz Digital Wireless Headphones, Model 2500

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.

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.

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.

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.

  Christian B., Australia

"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."
  Paul R., Canada
