What's the best iOS app for personalizing open-ear headphone settings?

Shokz is a dedicated companion app for Shokz open-ear headphones, providing robust customization tools that enhance audio experiences in various scenarios. For instance, runners can fine-tune the equalizer to boost bass during workouts without blocking ambient sounds, while office workers might use multi-point pairing to switch seamlessly between a laptop and iPhone during calls. The app includes specific features like a customizable EQ with presets for music, podcasts, and voice calls, real-time battery status for both headphones and charging case, and device management for up to two connected gadgets. Users report that the interface is straightforward, with reviews indicating reliable performance and minimal crashes. However, the app is exclusive to Shokz hardware, limiting its utility for other brands, and some may find the EQ options less extensive than standalone audio apps. Despite this, its focused design ensures stable operation and practical benefits for daily use.
