HiFiMAN Sundara
$71 under your budget
The planar to beat under $300 — faster transients, deeper bass and a wider soundstage than dynamics costing twice as much, and at 37 ohms it needs no amp.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
Its midrange isn't the last word. The Sundara wins on bass speed and soundstage, but the HD 660S2's midrange tonality and fit-and-finish are a clear step up — and as a planar it rewards a current-capable amp more than the price suggests.
Dealbreaker? Runner-up №3 (the HD 660S2) is the tonal step up past $250 ↓

Traps — this verdict avoids
Why the HiFiMAN Sundara is right for you
It avoids every trap below — and for just me, under $250, it is the pick because it delivers:
The amp tax
The 300-ohm Sennheisers (HD 600, HD 660S2, HD 6XX, HD 800 S) sound thin and quiet straight from a phone or laptop. Plan on at least $100 for a DAC/amp on top of the headphones, or you never hear what you paid for.
Zero isolation
Every pick here is open-back — it leaks sound both ways and gives zero isolation. Buy these for a quiet room, never for an office, a commute, or anywhere you can't blast music without annoying someone.
MSRP is a mirage
Street prices swing 15-40% during Prime Day and Black Friday, and models like the HD 660S2 and HD 600 already sit 40%+ under MSRP. Paying list price on these is simply overpaying — check the current street price first.
