Made for relaxing listening sessions, the Tanchjim Oxygen IEM delivers a dark, smooth sound with little fatigue. It uses the company’s proprietary 9.2-millimeter graphene dynamic driver, and boasts an ergonomic design for an excellent fit. Thanks to its compact size, the IEM doesn’t feel heavy in the ear, despite its stainless steel shells. The silver-plated OFC cable is a great choice for everyday listening, and you’ll also get a second cable with an inline microphone and remote. 

In a five-star review, Head-Fi user IryxBRO says, "Two main definitions followed us while we were examining the Tanchjim Oxygen IEMs and writing this review: accurate and clean. This addresses both overall design and sound … such a minimalistic approach, perfect crafting, clean look, and natural profile represent the maturity of this model, instead of incorporating a screaming design to hide some drawbacks behind its exterior. Sound quality and tuning spread this idea further: accurate and weighted delivery of all frequency ranges result in a balanced sound with slightly warmer tonality and a wide soundstage."
