Summary: I can't believe there is no review on this headphone. I will write a brief one because I am really not equipped and skilled to write reviews on this forum as deep and broad as other reviews resulted from extensive tests and auditions.
Excerpt: Sennheiser’s RS 220 package is basically a combo of the HDR 220 headphones and the TR 220 dock. And it is one huge box they come in! Our experience with most wireless headphones till now has been a serious case of two halves - lots of potential with some bit of deliverance on that, but disappointing...
Pros: Good sound quality, Neutral headphones ï¿½ should appeal to a wider demographic, Comfortable to wear, even for a long innings, Blocks out ambient noise quite well, Lots of input options
Cons: HDR 220 may be too big for some users, Limited range, Buttons on the headphone prone to getting pressed inadvertently
