        • I was honoured to be approached by iBasso with their first venture into IEM territory and they asked me to provide a review of their recently released earphone.

        iBasso are well know for their excellent Dap range so they know a lot about engineering and sound.

        These are beautiful looking and seem to have a type of custom design feel to them, for me the fit was fantastic and reminiscent of Stagediver SD range.

        They sit nice an snug in my ears and stay put when I’m on the go with nice isolation. I have heard that a small amount of people have fit issues but my understanding is the majority should have a great fit as iBasso carried out extensive researching into the design.

        The fit and design is something that will gel with many people and they worked great for me and I was also certainly attracted to the elegant style of the design.


        The nozzles have a strong mesh cover to protect from wax and debri which should help these endure.

        The connectors are gold coloured MMCX and have a real nice tight fit for all the cables I tried.

        I was very happy with this as my experience with MMCX sockets has been hit and miss in the past.


        The shells feel solid and well built, although they are a 2 piece shell design the join doesn’t effect in any adverse way.

        I really like the attention to detail of the curve precision around the golden MMCX socket.
