The Sennheiser HD-650 is an iconic audiophile headphone, noted for its low distortion and smooth, non-fatiguing sound. Featuring well-balanced bass, including very deep bass reproduction, the sound spectrum is realistically portrayed and very listenable. The ergonomics are excellent; these are headphones that can be worn for hours without discomfort.
The one area where the HD-650’s can be improved upon is the stock cable. It imparts a slight veiling to the sound. The phones for sale include a substantial cable upgrade – the Moon Audio Silver Dragon v3 (5 foot cable, terminated in ¼” heavy-duty, gold plated Furutech connector). This cable removes any veiling, while retaining the signature sound of these phones. The original (stock) cable is also included.
