About This Product
The HD 660S2 has no battery, no Bluetooth, and no noise cancellation — deliberately, since it's built for plugging into a dedicated headphone amp and listening critically at a desk, not for commuting. This category of wired audiophile headphone trades every convenience feature for sound accuracy, and buyers in this price range are typically already invested in a home listening setup rather than shopping for an all-purpose daily headphone.
