OLLO Audio embodies a fusion of passion and precision, dedicated to crafting top-tier studio headphones. The OLLO Audio S4R 1.3 Calibrated Headphones Closed Back Recording Headphones stand as a testament to this dedication, cherished for their exceptional versatility in mixing, tracking, and mastering.

Breaking the norm for closed-back headphones, the S4R delivers accuracy and detail while effectively isolating external sounds. Immaculate frequency separation stems from handpicked left and right-matched 50mm transducers, providing an accurate, flat sound profile suitable for professional use or recreational listening.

Achieving such sonic accuracy, the S4R features two dynamic neodymium speakers composed of a PET 25u membrane with a two-layered coil, boasting a low impedance of 32 Ohms compatible with various devices. Sound Seal Acoustics™ ensure complete isolation, complemented by replaceable ergonomically-designed earcups made from isolating acoustic foam, encased in ultra-elastic poly leather and soft velour.

Crafted in Slovenia to impeccable standards, these headphones feature a powder-coated spring steel headband with a self-adjusting artificial leather strap for optimal comfort. The detachable braided silicone cable with an OFC core prevents signal distortion and comes with color-coded L/R jacks and a switchable 3.5/6.3mm TRS jack adaptor for versatile connectivity.

As sustainability meets innovation, OLLO Audio ensures most headphone components are replaceable, offering upgrade kits to maintain the S4R's sonic performance, ensuring longevity in shelf life.
