For a lot of years, HD 650 headphones of Sennheiser have been an audiophile mid-range favorite, and now the audio brand of Germany has declared an heir to this device. The analogous-looking HD 660 S open-backs have compatibility with a lot of Hi-Res digital audio players, reduced impedance for drive, and more connectivity options along with enhanced harmonic distortion.
Open-back headphones normally provide a much improved and often more spacious sound than their more ordinary closed-back siblings, but the design does indicate that they do not leak music to those nearby and also block ambient noise, so are possibly most excellent suited for quiet room and home listening. That claimed, Sennheiser has lowered the impedance of the new headphones dubbed HD 660 S from 300 Ohms to 150 Ohms, indicating they can be boosted by Hi-Res mobile audio players from the likes of Fiio and Pioneer.
Mobile consumers rocking less able smartphones or music players along with most of the living room listeners might require pairing the over-ear buds with a headphone DAC/amp such as Sennheiser’s own HDV 820 model or the MHA50 from McIntosh to boost them. Sennheiser claims that its latest dynamic proprietary transducer design improvably manages the fabric stainless steel diaphragm, and when connected with aluminum high fidelity voice coils pledges lifelike audio and low harmonic distortion that has described as meaningful, yet transparent and accurate.
The latest reference headphones have the similar frequency range 10 Hz to 41 kHz as their predecessor, but provide 104 dB SPL and 0.04% of entire harmonic noise/distortion. They have analogous elliptical ear buds with thick padding on the headband and disposable ear cushions for long-haul comfort for listening. An oxygen-free removable copper cable concluding in a 6.35 mm gold-plated stereo jack is added in the box, plus one more cord concluding in a Pentaconn 4.4 mm stereo plug for unbiased connection to DACs. There is a 3.5 mm to 6.35 mm adapter added in the box, as well.
The Sennheiser HDD 660 S headphones carry a suggested retail cost of $499.95 and will be obtainable this month later. So, stay tuned guys!!!
