What people are saying
4 quotesDirect organic buyer opinions about Sennheiser Consumer Audio HD 660S2, filtered for spam and ads.
660S2 is the most punchy, most detailed, and most spacious from the HD6-series, but their midrange tuning is the most wonky...
They're really good and were shockingly easy to run, actually running fine out of my built-in headphone jack.
They're relaxed and smooth but still detailed enough to qualify as an audiophile grade experience...
Both the 650 and the 660S2 deliver that same lush, sweet vocal performance that people love.
