Our Verdict Very disappointing, the sound is dull and flat For Affordable volume control Against Tonally flat Reviewed on 16th August 2011 We’re told that this is the replacement for the Sennheiser Award-winning CX 300-II, and boy, are we disappointed. The ultra-affordable price remains and a handy volume control has been added, but the sound is tonally, dynamically and rhythmically flat. There’s nothing harsh in the delivery, but there’s nothing fun or interesting in it, either.
