The headband is constructed from powder-coated spring steel and features a self-adjusting strap, it attaches to the earcups via two 360-degree rotational brackets. The S4R cable is a detachable braided silicone cable with an OFC core that ensures signal purity from your device to the headphones. This cable comes with left and right (L=black/R=red) colour coding on the inputs, but they are reversible and can be attached to either PCB connector on each side.

The transducers are made from a PET 25u membrane with a two layered coil Requiring only 32 Ohms, the relatively low impedance of the S4R means it is compatible with most battery powered small consumer equipment and other everyday devices such as HiFi stereo amps. The sound Isolation and frequency separation characteristics of the S4R are attributed to the Sound Seal Acoustics ™ that separates the front and back of the earcup and the replaceable earcups made from isolating acoustic foam fits ergonomically around the ears and helps to reduce bleed from the headphones. The ultra-elastic poly leather and soft velour outer layer make the S4R earcups comfortable and easy to wear for extended periods of time.
Designed, assembled, and manufactured in Slovenia, the S4R headphones are built to an exceptional standard. The headband is made from powder coated spring steel and has a self-adjusting artificial leather comfort strap that keeps the headphones at a comfortable level. Plugged in vial a detachable braided silicone cable with an OFC core that prevents signal distortion. The cable is colour coded with black for left and red for right, but both cable ends can fit in the opposite embedded PCB connector and the end of the cable features a 3.5/6.3mm TRS jack adaptor that can be swithced to suit the equipment you're monitoring. OLLO Audio also strive to make their products as sustainable and upgradeable as possible. Most OLLO headphone components are available as spare parts and upgrade kits available for older versions of their headphones; you can be sure that even with the long shelf life of the S4R, you will be able to maintain them and retain the sonic performance.
