The section of Sennheiser’s product portfolio that’s (probably) headed ‘people who take listening very seriously indeed’ is pretty extensive - and with the arrival of these new HD 660S2 wired open-backed over-ear headphones, it gets its latest update.
‘Wired’ and ‘open-backed’ both denote serious (and solitary) listening, of course - but Sennheiser is promising a laid-back experience to go along with all the ‘precision’ and ‘control’ it always aims for with its higher-end products.
