#130 Austrian Audio Hi-X55: $345.51 Amazon eBay
Pros: The closed back blocks outside noise and keeps sound from leaking, so it works in shared rooms and studios. A 25 ohm load and 118 dB/V sensitivity let it run loudly from a phone or laptop, and it weighs a moderate 305 g. Bass sits about 1.1 dB above target with sub-bass still within 6 dB down to 20 Hz, which suits listeners after a warm, bass-leaning balance.
Cons: oratory1990’s measurement shows a deep 9.9 dB dip near 2.3 kHz and presence about 3.9 dB below target, so vocals and guitars sound recessed and distant. Sub-bass averages 4.1 dB below target, so the deepest rumble is lighter than the midbass suggests. Its preference score of 56 sits far from the Harman target.
