(More customer reviews)This sounds similar to some of the Altoids amps that hobbyist began making in the 1990s. It is made up of cheap opamps in a fancy wooden cigar box but it's still better than the headphone jack of most components. The hobbyists that made those Altoids amps (literally in little tin Altoids mints boxes) continued to revise, improve, use newer opamp chips, and better components... so this headphone amp is not nearly as good as those are. Avoid.
