Why You’ll Love It
The HOCO UPA35 Mia solves a common problem with modern smartphones and tablets: the disappearance of the traditional 3.5mm headphone jack.
Instead of replacing your favorite wired headphones or AUX accessories, simply connect them through the UPA35. Its integrated DAC handles the conversion from digital USB-C audio to the analog signal required by conventional 3.5mm audio devices.
Unlike an audio adapter intended only for music playback, the UPA35 also supports compatible microphones and wired headset controls, making it practical for calls, meetings and everyday communication.
Its cable-free 41mm design is especially convenient for travel and everyday carry. At just 4g, it takes up almost no space and can easily remain with your earphones or other mobile accessories.
