A4C offers the refurbished JBL Synchros Slate S500 Over-Ear Headphones in Black for $34.95 with free shipping. That's tied with our mention from two weeks ago and $30 under the lowest total price we could find for a refurb pair today. Features include 50mm drivers and a frequency response of 10Hz to 22kHz. They require two AA batteries (included). Deal ends July 30.
A 90-day A4C warranty applies.
