Short answer: the Teufel Rockster Air. It ranks #27 of 50 party speakers by sound quality; the Sony GTK-XB60 ranks #48.
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. The catch: Peaky midrange, not very natural sounding. Starts to get distorted above half volume.
On the Sony GTK-XB60 side: 60W powerful sound performance with extra-bass technology for deep, punchy output. 2x 5.12” woofers + 2x 1.97” tweeters. Set against that: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning.
Buy the Teufel Rockster Air if sound quality matters more than the price. Buy the Sony GTK-XB60 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Sony GTK-XB60. It ranks near the bottom of the 50 party speakers, so look higher up the list instead.
If battery life is a priority, the Teufel Rockster Air is rated for 30 hours versus 14 hours for the Sony GTK-XB60.
