Customer Testimonials




"These are the best wireless headphones I have ever had. They are in a different league."
  Andrew D., USA



"I recieved the headphones a couple of days ago and they are fantastic!! The range is superb & sound quality is brilliant.. i can't take them off!!"
  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
