Did you switch the connector from left side and put in right side and check if the problem is the transducer or cable problem. If not cable, why not write to audio research in Japan to see if it can be service. if unserviceable, i would find a second hand or discount set in the shop. Last year, there was a bargain in amazon uk which no longer available. Or go to shop which have them and bargain the price down. I think ar-h1 did not sell well, and shop are eager to get rid of them. I do not know why it does not sell well, i guess review on internet not so good, totally unfair, i have layla, ultrasone E8 and Sennheiser HD800, I thought i was in headphone heaven, until i get AR-h1. Now,I cannot listen to music on my other headphones without thinking of ar-h1. It is the cheapest hifi cans i have.
