Solve your headphone compatibility issues with Moshi's 3.5mm Headphone Adapter. This is the ideal adapter for plugging your headphones into a large battery case or weatherproof case with a hard-to-reach audio port. It also supports pass-through of all microphone and volume control signals. Gold-plated connectors provide maximum conductivity, while anodized aluminum housings and reinforced stress relief points are used for added durability. In addition to headphones, extend the reach of mobile credit card readers (like Square or PayPal) as well as 3.5mm mini-stereo cables used in home, school, and car audio systems. Simple yet built to last, this adapter is the perfect solution for hard-to-reach audio ports on your smartphone or tablet case.
