Apple has released iOS 8.3. In 8.2 the sound quality was improved with a stability update. In 8.3 many other aspects have had a stability update; not the sound quality. Yet it sounds different. Bas more controlled, detailed and on the background. Vocals and sprinkle sounds clearer and more on front. More stereo experience. What is your experience? What does your brain say? Is the sound in iOS 8 indeed better? (Best noticed with an high end head set).
