Short answer: the Onn XL Wireless Party Speaker. It ranks #14 of 50 party speakers by sound quality; the Teufel Rockster Air ranks #27.
What the Onn XL Wireless Party Speaker offers: An exceptional value in a party speaker. Includes 2 wireless microphones. Wheels and a built-in handle for easy transport. 5 multicolor LED lighting effects. Control display on the unit. Watch for: A little bright up top, not quite as well balanced as the JBL Partybox 330.
What the Teufel Rockster Air offers: Exceptional 58-hour battery (31 hours at full volume with ECO mode). User-replaceable battery adds real longevity. 112dB loud like live rock concert. Tight bass, solid build, clean full-range guitar output (legitimate practice amp). XLR mic/instrument/aux inputs with companion XLR daisy-chain. USB-A device charging. Party Link Stereo pairs two units wirelessly. Watch for: Peaky midrange, not very natural sounding. Starts to get distorted above half volume. Only available in Europe.
Buy the Onn XL Wireless Party Speaker if sound quality matters more than the price. Buy the Teufel Rockster Air if the price matters more than sound quality.
There is a real battery-life gap here: the Teufel Rockster Air is rated for 30 hours, the Onn XL Wireless Party Speaker only 16 hours.
If water resistance matters to you, the Onn XL Wireless Party Speaker at IPX4 (splashing) holds up far better than the Teufel Rockster Air at no water resistance.
