Bluetooth speakers are often boring boxes in plain colors, but not this one! As part of Nothing’s ongoing early Black Friday promo, you can grab its unique, milk carton-shaped CMF Speaker S from Amazon and Nothing for just $39. That’s a solid $20 discount and the lowest price we’ve seen on Nothing’s newfangled wireless speaker, which hit the market about a month ago.

The CMF Speaker S is the smaller of the two recently-released models — the larger Series M is also on sale at Amazon for $79 ($30 off) — and sports a 45mm driver with two passive radiators to help with low-end frequencies. It can run for up to 18 hours on a single charge and carries an IP68 rating for water and dust resistance. Despite its carefree aesthetic, it also supports stereo pairing with a second Seris S speaker, Bluetooth 6, fast pairing via multiple methods (including NFC and Google Fast Pair), and audio over USB-C.

In addition to their great sound and compact footprint, both the Speaker S and Speaker M feature removable faceplates and multifunction front knobs. Not only can you swap them out to customize the colors, but CMF plans to share STL files so anyone with a 3D printer can create their own attachments and looks.
