Short answer: the Teufel Rockster Air. It ranks #27 of 50 party speakers by sound quality; the JBL Eon One Compact ranks #36.
The case for the Teufel Rockster Air: Exceptional 58-hour battery (31 hours at full volume with ECO mode). User-replaceable battery adds real longevity. 112dB loud like live rock concert. The catch: Peaky midrange, not very natural sounding. Starts to get distorted above half volume.
What the JBL Eon One Compact gets right: Professional 4-channel mixer with XLR/TRS preamps, phantom power for condenser mics. 112dB SPL, lightweight 17.6 lbs with swappable 12-hour battery. 8-inch woofer extends to 37.5Hz. Watch for: Quite distorted at full volume. Treble is quite rolled off, not much clarity.
Buy the Teufel Rockster Air if sound quality matters more than the price. Buy the JBL Eon One Compact if the price matters more than sound quality.
If battery life is a priority, the Teufel Rockster Air is rated for 30 hours versus 12 hours for the JBL Eon One Compact.
