AAW x Custom Art Project 4+2 UIEM

More than a collaboration of efforts from Advanced AcousticWerkes and Custom Art, Project 4+2 is the meeting point for all your favourite technologies from Singapore's top custom earphone manufacturer.

Flagship Canary's dual isobaric dynamic drivers surface down here in 4+2, along with Halcyon's BassFlow port to tailor the presentation from this hybrid's low frequencies. NOVA, ACH's nozzle-less open balanced armature, pushes super tweeter details unmolested out at the very tip of the nozzle entrance. Headfonics nail it saying "you are getting a lot of technology trickle-down from each company's higher-end models into this monitor".

These – in the precisely moulded enclosure of a 3D-printed shell – provide the bedrock for Custom Art's FIBAE drivers to take care of mid-range frequencies, always promising rich, decadent tone and transparency. This sweetness from the Poles' flat impedance balanced armatures needs no introduction.

4+2 can also be bought in custom (CIEM) form moulded uniquely to your ears here. Also browse the rest of AAW's offerings here, or view our other universal IEMs here.
