Sennheiser HD 6xx (HD 650) Audiophile Headphones

Best in class audio quality and comfort, the perfect introduction to the audiophile world. These Sennheiser HD6xx (same as the HD650's but sold through Massdrop) sound incredible and are in perfect condition. I've only listened to them a handful of times. The truth is, these headphones need an amplifier and I don't want to shell out the money for one so I'm selling these and looking for a lower impedance headphone. Everything that comes with these headphones is included here, including their padded storage box and original packaging. Here are the details from the website: If you know audio gear, you know the Sennheiser HD 650. The company’s flagship from 2003 to 2009, this open-back headphone has shown serious staying power. Praised for its richly detailed, effortlessly enjoyable sound, it remains one of the most talked-about products on Head-Fi today—and is still widely considered among the best headphones under $1,000. So when we teamed up with Sennheiser on its first-ever community-driven design partnership, the HD 650 was a natural place to start. A new revision of the popular all-rounder, the Massdrop x Sennheiser HD 6XX has that same great sound plus a few updates, and a price that makes it even easier to love. More than 30,000 members have picked it up to date.  • Massdrop x Sennheiser • Color: Midnight blue • Transducer principle: Open, dynamic • Frequency response: 10 Hz – 41 kHz • THD: < 0.05% • Nominal impedance: 300 ohm • Cable length: 6 ft (1.8 m) • Connector: ⅛ in (0.3 cm) • Weight without cable: 9.2 oz (260 g) • Made in Ireland Thanks for looking!
