Wolverine WIOS2 Wireless Speakers
These innovative little speakers are suited to both indoor and outdoor use as they are designed to be water-resistant (we'll resist making references to that little suite by Handel - that should still play fine!).
The wireless capability means that it is possible to connect a music source - CD player, iPod or even smartphone - to the transmitter base indoors while the speakers deliver the sound outside on the patio or deck.
They may be powered by either batteries or AC. Users report fairly short battery life so investment in rechargeables may be necessary.
The speakers' appearance is well-received by users, though appreciation of the sound quality is more variable, with most users delighted and full of praise while occasionally others are more ambivalent in their responses.
