Unique Melody is proud to introduce the world’s first quad balanced-armature/dynamic-driver hybrid! That’s quite a mouthful, so we’ll summarise it for you in one word, bass – and lots of it! The Merlin side steps for our usual neutral sound signature to reproduce drums, guitars and anything else bass with, well even more of it in a powerful, impacting way.

As the result of thousands of hours of research and development, the Merlin takes a novel approach by combining four dynamic armature drivers and a single hybrid driver to create a truly revolutionary custom in-ear monitor. The end result is a phenomenal bass extension going as low as 10Hz (trust us, that’s low)!


Your customs are your own, any colour, any artwork – its that simple. You can choose separate colours for the tip, shell and faceplate of your earphone. Of course, there are lots of shades of red so we use a RAL colour code to standardise colours and get the best match!

You can even go wild and hit up one of our premium faceplate options including titanium, real wood, real carbon fibre and even crystal jade.
