Headphones and prog rock have a complicated relationship. These are albums mixed for enormous speaker rigs in proper studios — the stereo field on a peak-period King Crimson or Tangerine Dream record is wide enough to feel like a room. A cheap pair of earbuds collapses that into a narrow corridor and calls it music.
Open-back headphones are almost always the better choice for this kind of listening. They let air move, the soundstage breathes, and you get something closer to the feeling of sitting between two speakers. The tradeoff is leakage — people around you will hear what you're hearing, and you'll hear them. For home listening, that's an easy trade to make.
Five Pairs Worth Owning
Sennheiser have been making reference headphones since the 1960s and the entry-level HD line carries those values at a fraction of the price. The HD 559 in particular has a wide, relaxed soundstage that suits long progressive pieces well — it doesn't fatigue over the course of a 40-minute side, which matters more than any spec sheet number. The bass is honest rather than hyped, the mids are clear, and the high end doesn't bite.
The ATH-AD700X is one of the most consistently recommended open-back headphones at this price point, and for good reason: the soundstage is genuinely wide, almost unnervingly so for the price. On a record with a lot of spatial movement — the kind of psychedelic mix where a guitar solo starts left and drifts slowly to the centre — you feel that movement rather than just noticing it. Lightweight, comfortable for long sessions, and detailed without being harsh.
The DT 990 Pro is an open-back workhorse that has been in continuous production for decades because it works. The high frequency extension is notable — some people find it slightly bright, but on complex prog mixes it means you hear the detail in percussion, the shimmer of mellotron tape, the edge of a fuzz pedal. The bass is controlled and the mids are transparent. They're built to last, with replaceable ear pads and cables, and they're comfortable for three-hour listening sessions.
Not everyone listens at home. If you need closed-back isolation — on a train, in a library, in a shared flat — the Sony MDR-7506 is the professional standard that has been in recording studios since the late 1980s. It folds flat, the cable coils, and the sound is accurate enough that engineers have mixed platinum records on them. The soundstage is narrower than any open-back at this price but the detail retrieval is exceptional. The low end is honest, not flattered.
The HD 660S2 is the best open-back headphone at this price point for music that demands nuance. The transient response — how fast the driver reacts to sudden changes in the signal — is exceptional, which means fast, complex prog passages retain their shape rather than smearing together. The low-end extension goes deeper than any previous HD model without losing control. On a well-mastered progressive record, the experience is genuinely close to a high-quality speaker system in a treated room.
A Note on Amplification
Open-back headphones at the higher end of this list — particularly the DT 990 Pro (250 ohm version) and the HD 660S2 — benefit from a headphone amplifier. The headphone output on a laptop or phone typically can't drive high-impedance headphones to their potential. A dedicated amp in the $80–$150 range, like the FiiO E10K or the Schiit Magni, will make a genuine difference. Pair it with a USB DAC and you've built a proper desktop listening setup for under $600 total.
The short version: under $150, the ATH-AD700X. The compromise pick for travel, the Sony MDR-7506. For a proper home setup, the Beyerdynamic DT 990 Pro. If you want the best, the HD 660S2. Buy the amp too.
