Analysis
The Sennheiser Orpheus HE90 is a reference over-ear with 120Ω impedance and 94dB sensitivity. At 120Ω, 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 reference headphones like these.
