Price history
If you've been on the fence about upgrading to a proper pair of audiophile headphones, $395 is a meaningful entry point for the Sennheiser HD 660S2 — down from $680 and about $82 less than anywhere else right now. Rated 4.5 out of 5 stars across 734 Amazon reviews.
The 660S2 sits in Sennheiser's legendary 600 series lineage but is tuned differently from its siblings. Where the HD 600 leans clinical and studio-accurate, the 660S2 goes warmer and more musical — extended sub-bass down to 8 Hz, slightly softer highs that still resolve detail without fatigue, and an open-back design that makes the soundstage feel genuinely spacious rather than boxed in. Long listening sessions are where these shine.
A few things to know going in: these are wired and open-back, so they're not for commuting or noisy environments — they're a home listening headphone. You'll also get better results pairing them with a DAC/amp than plugging straight into a laptop. The cables are detachable, and Sennheiser sells replacement parts for nearly everything, so these are realistically a decade-long investment rather than something you'll replace in two years.
Not the right buy for everyone at this price, but for serious music listeners they're hard to argue with.
