This headphone is a remarkable feat of engineering—a solid bridge between wireless freedom and wired fidelity. Impressive as the RS 170 and the RS 180 were, however, they were a different flavor of awesome, that flavor being outstanding-for-wireless headphones; whereas the RS 220 is an outstanding headphone, period, even by wired standards. The RS 220 has become my most-used full-sized over-ear headphone, as it gives me the freedom to move around my home office area, moving from my desk to my chaise to my sofa, with fidelity that evokes the sound of a nicely driven Sennheiser HD 600.
Well said, jude. Fortunately, I have a pair of these magnificent Sennheiser RS 220 for sale. Although I definitely agree with jude's observations, I am on the road far too much to take advantage.
Unlike most of the listings on Head-Fi, my Sennheiser RS 220 actually qualifies for a 10/10 on the Audiogon Grading Scale. While I have used the Sennheiser RS 220 for around three months, most of the plastic wrappings still remain on the headphones. In accordance with the Audiogon Grading Scale, there are absolutely no visible (or invisible) scratches, nicks, or blemishes anywhere on the piece. The gold plating on input/output connectors evidence no scratches or discoloration.
Furthermore, all original accessories, documentation, media, packaging and receipts shall be included. In other words, you will be receiving everything I received when I purchased the headphones from a Sennheiser Authorized Retailer.
I have extensive feedback with several online communities, including but not limited to eBay, HeatWare and reddit.
