Amazon’s second-generation Echo has the benefit of easily swappable shells, and today the company announced that it’s releasing a red version of the smart speaker to benefit (RED) and its fight against AIDS.

Other than the unique color, the (RED) Echo is identical to the regular version. The only difference is that for every (RED) Echo sold, Amazon will donate $10 to the charity. Plenty of tech companies have teamed up with (RED) in the past to release special versions of their products. Apple has famously released numerous iPods and accessories over the years to support the charity, including a red iPhone 7 earlier this year.
