Sennheiser HD 660 S (508231)
 | Expecting restock High-quality open-back on-ear headphones with a soft, balanced sound of superior quality. The older model in the HD 6XX line, whose devices allow you to get the most out of listening to Hi-Res tracks. Designed for use as part of a complex of high-quality sound-reproducing equipment in a calm home environment and comfortable acoustic environment. They feature impressively low harmonic distortion, extended frequency and excellent dynamic range. With a lively and balanced sound, the Sennheiser HD 660 S headphones are able to convey to the user every emotion and nuance of the sound of a piece of music. They have a significant impedance resistance (150 ohms), so an additional high-end amplifier or a specialized Hi-Fi player is required to fully reveal their potential. Excellent ergonomics make...long hours of listening as comfortable as possible. They are equipped with a detachable three-metre cable with a two-way supply and a 3-pin Jack 6.35 mm connector, as well as an adapter for a 3-pin mini-Jack 3.5mm.

Very decent sound even from the built-in sound card, comfortable, good looking Not tight. Despite the impedance of 150 ohms, they are handled by the built-in Realtek ALC 1200. It's possible to comfortably get by for a few months while saving up for a good DAC and amplifier. Good bass, comfortable.
