am an audio enthusiast of long standing & the general word is unfortunately pessimistic because real world performance has been rather poor.
Yes, many makers are offering them now because makers do tend to offer anything fresh that the marketplace might accept.
These are now being offered across a wide price range. As a believer in getting just what you pay for, please get out to showrooms that have these as you will have to seriously audition them to make a proper decision. Remember, wireless speakers still have wires - power cords that is.
Even though it may seem like a real pain, I would take a serious look at routing speaker wire inobtrusively.
We moved and took our Panasonic surround sound system with us. Now, I need to install the rear speakers. But, I don't want to run or deal with hiding speaker wire. Does anyone have any info on purchasing a set of "rear" wireless speakers?
