While the company hasn’t always delivered clear class leaders, Sennheiser’s reputation is solid. That isn’t about to change with the CX 3.00.
Beginning with Alexis Weissenberg’s interpretation of Sergei Rachmaninov’s Prélude No5 in G Minor, the performance sounds human. The headphones capture the dynamics well and you can feel Weissenberg becoming alternately aggressive and withdrawn as he moves through the piece.
Timing, too, is good. The CX 3.00s track the polyrhythm in Atoms For Peace’s Before Your Very Eyes… with ease, and while it could be weightier, there is enough bounce in the bass guitar and synthesizer to send Thom Yorke into one of those epileptic caterpillar jigs.
What’s lacking is a little detail. The crispness of each note is sometimes lost in Rachmaninov’s Prélude, as it is with some of the synthesised noises and samples that make up Atoms For Peace’s complex percussion. A rounding off of the treble, which tends to dampen what should be two lively pieces of music, doesn’t help.
Minimalists will be pleased by the CX 3.00s’ muted design: they come in a choice of black, white or red, the cable is clean of any mic or volume control (though that does mean they weigh only 12g) and, but for modest logos on each ear piece, the brand is largely anonymous.

In general, they’re comfortable. There is a carry case and four options of ear buds, so a good fit isn’t difficult to find.
Cable noise is only a minor issue so most of the time you can enjoy what is essentially a balanced overall sound, only lacking some detail and clipped somewhat at the top end.
For £40 they’re good, but, if you can stretch to the extra £15, your investment would be better placed in Klipsch.
