Woot is now offering a selection of Bluetooth audio and home theater gear at up to 67% off with deals starting from $15. One standout here is the Ultimate Ears WONDERBOOM Waterproof Bluetooth Speaker (Phantom Black) for $49.99 with free shipping for Prime members. Otherwise, a $6 delivery fee will apply. Originally $100, and while we have seen it go for less than $50, this model sells for $63 at Amazon with the newer WONDERBOOM 2 — one of our favorite speakers of its type — fetches closer to $75 or $80. The original WONDERBOOM is still a great Bluetooth speaker with 10-hours of battery life, a completely waterproof design (it even floats), and a sound “that is clear, crisp, and full of big, beautiful bass.” Ships with a 2-year Logitech warranty and carries a 4+ star rating from over 9,600 Amazon customers.
