A4C offers the refurbished Logitech Ultimate Ears Boom Portable Speaker in Night Black, model no. 980-000678, for $139.95 with free shipping. That's $30 under the lowest total price we could find for a new unit, although we saw it new for $25 less in February. (Most stores are now charging around $200 for a new unit.) This wireless speaker features a 3.5mm auxiliary input, NFC, and up to 15 hours of music per charge.
A 90-day A4C warranty applies.
