Analysis

The Sony WF-1000XM4 is a high end true wireless with 16Ω impedance and 104dB sensitivity. At 16Ω, these headphones drive well from most phones and computers without needing an external amplifier.

Your audio source matters more than most people think. Spotify High Quality is fine for casual listening, but with FLAC files or lossless services like Apple Music or TIDAL you'll hear a clear improvement — especially with high end headphones like these.
