What the Onn Small Rugged Speaker offers: A highly portable 286g, IPX7-rated speaker with USB-C charging, a built-in mic, aux input and Party Sync support. For a very small, single-driver speaker it is easy to throw in a bag and owner feedback is consistently positive about its straightforward setup, toughness and everyday sound. Watch for: Its 1.5-inch driver cannot create meaningful deep bass (about 66Hz at -10dB) or the clarity and scale of better small speakers.
