Outlet MP3 via eBay offers the refurbished Logitech Ultimate Ears Boom Portable Wireless Bluetooth Speaker in several colors (Black pictured) for $49.99 with free shipping. That's $10 under last year's mention of a used unit and the best price we've seen. (It's a low by $10 for a refurb today.) This wireless speaker features a 3.5mm auxiliary input, NFC, and up to 15 hours of music per charge.
