The Review

So for this review, I used a number of headphones. These included the HiFiman Sundara and Ananda, Sony MDR-1AM2 in 4.4 balanced, Sennheiser HD599 and a selection of IEMs from Fiio and others. I also listenend to as many different genres as possible from jazz, blues, dance, rap, hip hop, classical, pop, rock, electronic and orchestral.

For starters, I really appreciated the 4 way gain switch for a more precise adjustment. The HiFiMan Planar Magnetic headphones benefited from a +6db gain. With IEMs the floor background noise was non existent on the IEMs that I used. The bass boost and 3D spatial options are nice options to have to as some of my headphones can sound too bass light.

However this combo is an incredible system, and as a consequence it powered every headphone I tried effortlessly. Apart from the sound, the design looks luxurious and would be at home in any room in the house. The freedom of using the ZEN Blue with portable devices like your smartphone, and in my case my Samsung Galaxy Note 20 Ultra, meant I had LDAC quality music streaming to the ZEN Blue. The ZEN Can is full of dynamics and blew the cobwebs off some of the headphones I hadn’t used for a while. It also possessed good detail, wide sound staging. TBH the two components together make a cracking piece of kit.

Video Review


Freedom from wires with the iFi ZEN Blue with all the respective hi-res bluetooth codecs coupled with the iFi ZEN Can is a formidable combination and highly recommended. 9.8/10.
