The Sennheiser HD 660S (approx. $351 / £399 on Amazon) has a good reputation among audiophile hi-fi fans due to its high sound precision and lively sound. However, some music lovers may find the bass of the open Sennheiser headphones to be a bit weak. Sennheiser addresses this issue in the HD 660S2, promising a stereo headphones super bass model.

Visually, the HD 660S2, also designed with an open design, differs little from its predecessor. Instead of a silver-colored logo and lettering, the HD 660S2 features a copper-colored tone. Sennheiser has made some revisions and optimizations to the HD 660S2, including improved airflow around the converter, refined voice coil, and reduced weight.

The HD 660S2 is expected to retain the clear, fine, and clean resolution of the HD 660S across the entire frequency range while producing a much more impressive dynamic sound image in the bass range. The modified transducer surround flexibility lowers the resonant frequency from 110 Hz in the HD 660S to 70 Hz in the HD 660S2, according to Sennheiser, resulting in powerful bass drums.

The HD 660S2 comes with two detachable cables, each measuring 1.8 meters, with 6.3mm and 4.4mm stereo jack plugs. A 3.5mm adapter is also included, allowing for use with popular hi-fi equipment such as DAC amplifiers, DAPs, and amplifiers such as the Sennheiser HDV 820.
