Koss 181066
The 13mm driver delivers a standard 60Hz-20kHz frequency range through a simple wired connection. Its pink in-ear design offers basic functionality at a budget price point, though call quality scores a low 7.2/100. This product is best for users needing an inexpensive, no-frills wired earbud for casual listening only.
