Analysis

The HiFiMAN HE400SE is a mid range over-ear with 25Ω impedance and 91dB sensitivity. At 25Ω, these headphones benefit significantly from a dedicated amplifier. Without one, volume and dynamics are noticeably limited — you're leaving performance on the table.

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 mid range headphones like these.
