The ER audio unit is a premium home sound system offering optimum versatility, convenience and audio performance. My product consists of a mains-powered home hub and up to four wirelessly linked portable speakers. When the portable speakers are placed on top of the hub they are charged wirelessly and instantly synchronise to play simultaneously from the same playback device as the hub. The portable speakers can then be moved around the space, allowing the user to adapt the sound system and ensure audio clarity regardless of where within their home they wish to be. My product offers all the convenience and versatility of a regular wireless speaker, but with improved performance due to the extended bass range of the home hub and none of the hassle of charging cables.

The portable units will also function independently if powered off and on again and utilise a single 20W full-range loudspeaker and powerful 50hr lithium battery pack. The hub contains a 5-inch woofer and is powered by a 70W class D amplifier used in professional studio monitors, a high-quality wireless receiver and a wireless charging for the portable units.
