Sony XB23 vs Soundcore Flare 2

Last updated: August 28, 2026

Short answer: the Sony XB23 if sound quality matters most, the Soundcore Flare 2 if price matters most. The Sony XB23 ranks #64 of 136 medium speakers at $100. The Soundcore Flare 2 ranks #105 at $80, $20 cheaper.

What the Sony XB23 offers: Reasonably neutral. IP67 rated with a strap hook for backpacks. USB-C charging; up to 12 hour battery life. Watch for: Bass drops off a ton at high levels. Reduces its own volume over time when turned to max

What the Soundcore Flare 2 offers: Try Alan Ross’s EQ for it Watch for: Rolled off treble. Thuddy bass. Not technically a 360 speaker, only front and rear.

Buy the Sony XB23 when sound quality outweighs the price for you, and the Soundcore Flare 2 when the price outweighs sound quality instead.

The Soundcore Flare 2 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.

Water resistance is not close: the Soundcore Flare 2 is rated at IPX7 (brief submersion), well ahead of the Sony XB23 at IPX4 (splashing).
