I have a set of Sennheiser HD120 wireless headphones hooked up to the RCA outputs of my setup. The sound from them is decent enough with one caveat... analog noise. I just am sick of it and I'm looking for anyone who has used a set of digital headphones who has an opinion of their experience. My viewing is typically after dark, regular TV shows or some sports, never any significantly critical listening, so pure wired quality isn't my goal. My goal is to be able to move around my room/house with a centralized headphone location and be able to hear the TV free from analog noise like I'm getting with my 900mhz (?) model and move to a digital model which will get rid of the noise as close to 100% as possible. I'm thinking something like the Sennheiser HD170s if they can do it. http://www.amazon.com/Sennheiser-Digital-Wireless-Headphone-System/dp/B002SOW65S/ref=sr_1_8?ie=UTF8&s=electronics&qid=1266088910&sr=8-8 Any thoughts?
