Facing the challenge of a one-day, several-hundred-kilometer long-distance ride from Taipei to Kaohsiung, the long dark night and steady headwind cruising often call for music. For this reason, CT Yeh personally acquired a bass-heavy SoundBot SB525 Bluetooth speaker for an unboxing and hands-on test. The video first demonstrates how the speaker fits snugly into a road bike's bottle cage and its stability, then sets up professional recording microphones to play various music genres, meticulously capturing the clarity of highs and the actual feel of low-frequency vibrations. Can this budget speaker, with its volume and sound resonance in the bottle cage, become the best companion for long-distance endeavors?
