Комментарий к профессиональному отчету Apple A2155 USB-C to 3.5 mm Headphone Jack Adapter Neutron 44
Этот "переходник" предназначен для НЕApple мобильников (т.е. конкурентов) и возможно по этой причине он специально в два раза тише по громкости. Хочешь от Apple громкий звук - покупай iPhone и A1749 Lightning Audio Adapter.
