ELECOM Wired Mini with Canal Single Ear with Conversion Cable To Black Headset, 3.5mm 4-pole Plug, Microphone, In-Ear, Type, Use, (4-pole 3-pole),

This is a single-ear, in-ear wired headset with a built-in microphone arm, suitable for web conferences, video calls, online learning, and voice chat during online games. Equipped with a φ3.5mm 4-pole mini plug (CTIA standard compliant), it can be directly with smartphones, tablets, and PCs equipped with a φ3.5mm 4-pole mini jack. A conversion cable with two φ3.5mm 3-pole mini plugs (one for microphone, one for headphones) is included, so it can be with older computers that do not have a 4-pole mini plug headset jack. With its easy connection—simply plug in the cable—it requires no setup or charging, allowing you to join calls immediately. This is a single-ear headset that allows you to hear ambient sounds. *Left ear only
