iFi was born in 2012 with one goal in mind: to produce 'ultra-fidelity' audio products that push the sonic envelope whilst still priced within the mainstream.

iFi audio is under our parent company, AMR, Abbingdon Music Research, which designs and produces top-end luxurious audio products. AMR saw in 2010 that customer demand for wireless and portable headphones was expanding as the whole audio dynamic was changing. Thus, iFi was launched.

iFi offers small but prodigious personal audio products thanks to the superior knowledge of AMR’s technology. Today, we are proud of our British (and international) roots. We continue to design and produce over 35 different products. We are headquartered in Southport, UK with distribution including retailers such as B&H and etailz with production overseas.

We source parts from around the world from manufacturers including AMOS (UK), GE Valves (USA), WIMA (Germany) and TDK (Japan).
