Introducing the EVA Earphone Jack Cover, a new mobile accessory that has been asked to create a reliable product using the technology and experience cultivated in the design and manufacturing of racing components. The earphone jack cover is precisely machined from solid duralumin wood, and the rubber O-rings are used for this model to achieve waterproof and dust-proof. The head part of only 0.2 inch (6 mm) in diameter, has been faithfully reproduced with the "NERV" logo using laser engraving. The work of art is worth seeing In addition to the ability to protect the earphone jack hole from water and dust, the color anodized cover adds an accent to the look. Can be used for earphone plug holes for iPhone or other smartphone.
