These Sennheiser Open-Ear Wired Headphones Are Now Nearly 50% Off
If you’ve been waiting for a deal on wired headphones , the Sennheiser HD 660S2 are currently on sale at Woot for $349.99, down from their original price of $679.95. That’s a major price cut for headphones that typically don’t drop below the $400 mark elsewhere — for reference, they’re currently $415.90 on Amazon . Plus, Prime members get free standard shipping (non-Prime shoppers pay $6 for shipping), and they’re backed by Sennheiser’s two-year manufacturer’s warranty . Woot doesn’t ship to Alaska, Hawaii, or P.O. Boxes, though.
The HD 660S2’s open-back design gives you a wide, natural soundstage that makes instruments and vocals seem more spacious. And with 300 ohms of impedance, they work best when paired with a good amp or DAC, delivering deep bass without being muddy; even at higher volumes, the sound remains clear and detailed. Comfort is also well-handled—the velour ear pads are soft, and the headband has precise grooves for a snug, repeatable fit. Long sessions are fine for most, though you may notice some fatigue after a few hours, depending on how sensitive you are.
There are a couple of small compromises. There’s some sound leakage, as with any open-back design, so they’re not ideal for shared spaces. Also, while they include two cables (one with a quarter-inch jack and one with a balanced 4.4mm plug), both are just under six feet long — fine for casual setups, but perhaps a bit short for studio setups or larger rooms, this PCMag review notes. Still, for those who want clean, balanced sound without artificial tuning and don’t mind being tied to a wire, the HD 660S2 offers plenty of value for the price.
