According to the German website, the OPTICON 1 is excellent in every aspect.

After testing OPTICON 1, AREADVD praises these small speakers for its rich acoustics despite its compact cabinet. The OPTICON 1 fulfills the room in a homogeneous way with sound and delivers a clear and coherent sound with characteristic details. The high frequency range interacts with the mid-range frequencies in an excellent way. AREADVD states that the OPTICON 1 is a classic noble compact shelf speaker, which convinces its audience with its dynamic sound and bass performance. With an excellent build quality and a sound that sounds larger than its size, the OPTICON 1 is the perfect speaker for sophisticated music lovers.
