Analysis

The Grado SR125x is a mid range on-ear with 32Ω impedance and 99dB sensitivity. At 32Ω, 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 mid range headphones like these.
