We’re excited to announce a new collaboration with Mastering.com, the premium destination for online education in audio. Mastering.com has taught thousands of students and shared its courses with millions online. Their approach goes beyond just great curriculum; it emphasizes the importance of expert mentorship and a thriving, supportive community.

OLLO Audio announces the discontinuation of the S4R closed-back studio headphones. The S4R series, built on the foundation of the original S4 series, shared the same chassis and speakers, making them an excellent match with the S4 mixing headphones and later the S4X.

Online headphone audio demos often lack a reference point due to the acoustic impedance of ear simulators and individual headphone characteristics. The video seeks user input on improving these demos by sharing their headphone models and suggestions. It emphasizes using consistent tracks and calibrated SPL levels to enhance demo reliability. The video also explains the importance of using ERP (ear reference point) simulators over DRP (drum reference point) simulators to avoid ear canal resonance issues. Viewers are encouraged to contribute via comments and a dedicated subreddit.
