The construction of the Sonora, thanks to the fully aluminium material and CNC process, is exceptional. The standout feature of the design is that the aluminium is remarkably sturdy and solid, yet the IEM remains lightweight. Thus, you enjoy both a robust build and lightweight shells combined. Overall, it boasts a worthy design and construction, which is to be expected given the price. Design is always subjective, but I found the new Sonora appealing with its attractive gold-coloured faceplate, red body, and sharp angles. Undoubtedly, it presents a very special and premium aesthetic from PlusSound.

In terms of the cable, PS utilise custom hardware for connectors and plugs; in this instance, the cable boasts exceptional quality. It is expertly braided with remarkable consistency. The hardware is remarkably good. The 2-pin connectors must be aligned with the logos facing inwards, as the screws need to be outward, which is contrary to the approach of many other manufacturers.

Opening the Noble FoKus App I selected “Personal EQ” to try out the Audiodo Sound Personalization Software. This proved to be a different process than I experienced with previous FoKus headphones, testing each ear individually, the results were rather interesting and did seem to improve the sound though I did decide to take a second test when my ears were more rested. The results of my second test were very interesting, while the results of my initial test showed a similar curve for both left and right ear with my left ear being about 5 dB more sensitive than the left, in a rested state my right ear flattened out a bit and high-frequency hearing sensitivity increased significantly on both, which is something I expected hence the second test.
