Do you happen to own a HTC-based product? Well, there is now a 3-in-1 ExtUSB Headphone Adapter that enables you to use a standard 3.5mm stereo headphone with your HTC devices instead of HTC’s proprietary headphones which frankly, aren’t up to par when it comes to audio performance. Not only that, you will be able to hook up a microphone to it as well while the additional USB port offers an extra avenue for charging your HTC device. It retails for an affordable $15 a pop.
