True Dynamic Sound Reproduction and Treble Clarity by Aluminium Chamber

The HS1503 AL is made of aluminium CNC milling and there is solid construction, It boasts an unorthodox industrial design which helps to create a nice unique appearance. On outside of the iem, there is a circular shaped metal sticking out. There are 3 metal screws on the faceplate. On the inside of the iem, there are L & R markings on the left and right side respectively. The nozzle is slightly angled with metal mesh and there is a vent. The brand and model name are printed on the rims. The iem utilizes MMCX connectors and on the MMCX sockets, there are blue and red ring on the outer edge to differentiate between left and right. I am able to fit the iem comfortably in my ears.

The cable has a braided design and it is black in color. It uses MMCX connectors with a opaque black housing. On the MMCX connectors, there are L & R markings to differentiate between left and right respectively. The chin slider and y splitter are black in color. The jack is 3.5mm gold plated right angled and the housing is black in color. There is strain relief. The cable is rather flexible.

The HS1503 AL extends it sub-bass competently and it is able to deliver an impactful rumble with a moderate speed. The quantity is sufficient although it does not operate on a full-bodied bass reproduction approach. The mid-bass on HS1503 AL has a moderate amount of body and there is a consistent agile slam. Bass texture on the HS1503 AL is moderately smooth while the bass decay is quick and enhances the overall punch. Each bass note is articulated with precision and there is good tightness. There is a clean attack with great definition.
