Brookstone weather-resistant wireless speaker with transmitter dock (model 656736). Tested and working — I've been using it, just thinning out electronics.
How it works: plug the little transmitter into any audio source (TV, stereo, receiver, computer, or a phone with a headphone adapter) and the speaker picks it up over 900MHz RF from up to 150 feet away — through walls, no line of sight needed. Great for a patio, deck, garage, or workshop where you don't want to run speaker wire. I've been using it with a streaming device plugged in to the transmitter and then just put the speaker outside or wherever I am.
Includes:
• Speaker
• Transmitter dock
• Both AC power adapters
Features: volume, bass boost, and LED accent light on the speaker. 3 selectable channels to avoid interference. Aux/MP3 input on the speaker itself so you can also just plug straight in. Can run on D batteries if you want it fully cordless.
Heads up so there are no surprises: this is RF, not Bluetooth. You can't pair a phone directly — the transmitter needs to plug into a source. If you want a plug-and-play Bluetooth speaker, this isn't it. If you want to send audio from your TV or stereo out to the patio without running wire, it does that really well.
