With the USB-C line-in adapter, audio is described as clean and low-latency for external sources, though some use cases can affect mic-dependent features.
The 3.5mm aux input is viewed as a meaningful bonus at this size and price, especially for wired sources like computers or players. It is also repeatedly noted that USB-C is not used for audio input.
Wired playback via USB-C is repeatedly highlighted as a strength, with multiple sources describing a noticeable uplift in clarity, detail, or dynamics when using hi-res or lossless files.
The analog aux input is valued for turntables and legacy sources, but multiple reviews note that analog is still processed through the internal DSP chain, which some purists may not love even when the results sound clean.
AUX input is appreciated for flexibility, but at least one review notes that using AUX disables the Bluetooth connection and can prevent stereo pairing, which limits how you can use wired sources.
