It is not an object shaped like a speaker that only functions as a smartphone stand. Also, it is not a poor-quality product that leaks sound, sounds muffled, or has excessive reverberation that causes the sound to crack. ★ About Sound Effects... ・ Sound effects are greater with higher volumes. The effect is reduced at low volumes. ・ The better the sound quality of the sound source, the better the sound effects. ・ Sound effects vary depending on the type of music. ・ Acoustic sounds (especially string instruments, percussion instruments, and vocals) become clearer, and the sound feels more expansive. ・ We do not recommend electronically produced electronic sounds or digital sound music...
