        • Excellent low end bass spectrum coverage
        • Great imaging and positioning
        • No peaks or sibilance


        • Maybe too relaxed for some and lacking in energy at times
        • Vocals a little distant
        • Hiss on some sources

        The cables come with strong build L shaped 3.5mm single ended jacks that are re-enforced to help with any cable flex. nuforce HEM8 Review

        The cable connectors are 2-pin sockets but have a plastic circular outer section to hold more securely with the shells and colour indicators to show left and right.

        These fit extremely securely to the shells and I don’t see these falling off easily. nuforce HEM8 Review

        The 2 supplied cables are well built and I experienced hardly any micro phonics, these connectors stayed securely in place while on the move.

        The cables are made of OFC and silver, while the 2-pin cable connectors are a proprietary mix of silver and copper with separate ground return for each channel.

        • Detachable OFC high-end audio cable (1.38m)
        • Detachable cable with controls & mic (1.38m) nuforce HEM8 Review

        I think the large case, cables supplied and accessory selection are excellent. I can’t see any further additions required.
