The best way to compare speakers is by combining A/B testing with extended listening.
A/B testing (quickly switching between speakers using the same song) highlights immediate differences in tonal balance, bass, vocal clarity, and treble sharpnes. It helps pinpoint detail retrieval, imaging, and frequency response.
Longer listening sessions (a day or more) reveal how a speaker feels over time. Some sound exciting at first but become fatiguing, while others grow on you. Testing different genres and volumes helps assess dynamics.
Start with A/B testing for a first impression, then follow up with extended listening to gauge long-term comfort. If possible, have someone switch them blindly to minimize bias. This balanced approach ensures the best choice.
