What's the best iOS app for adjusting ambient sound and noise cancellation on wireless headphones?

JBL Headphones is a companion app specifically designed for Harman's JBL wireless headphones and earbuds, offering detailed customization of audio features. For users seeking to manage ambient sound and noise cancellation, this app excels with its straightforward interface that allows seamless switching between modes. Key features include Ambient Aware mode, which lets users blend external sounds with their music for situational awareness—ideal for outdoor workouts or commuting—and active noise cancellation for immersive listening in noisy environments. The app also includes customizable earbud controls, enabling users to assign functions like play/pause or volume adjustments via touch gestures, though some reviews note that the physical earbud controls can be confusing without the app's guidance. In real-world scenarios, such as during a run in a busy park, users can enable ambient sound to stay alert to traffic while enjoying high-quality audio, or switch to noise cancellation in a crowded cafe for focused work. User feedback highlights the app's role in enhancing headphone functionality, with one review stating, 'The noise cancellation work like a charm.' However, a limitation is that the app is exclusive to JBL devices, so it won't work with other brands. Despite this, its no-ad design and reliable performance make it a practical tool for optimizing wireless headphone experiences.
