Hello, I have a gpx450, atx, and a gold bug pro. I have been researching and looking for a wireless setup. From everything I've read tdk wr700s were about the best. So I gave them a shot so far they sound horrible on the atx and I haven't tested on anything else yet. I also seen a airheadz brand that looked over priced, headphones looked nice but it just has a cheap Bluetooth transmitter. Is there anything out yet that is worth a darn?
