Our All-Time Best Seller
Based on Sennheiser’s flagship headset from 2003 to 2009, the HD 650, our open-back Sennheiser HD 6XX headphones let you hear more detail than ever before.
Modern Midnight Blue
Designed for the modern listener, the HD 6XX swaps the HD 650’s gray colorway with a darker, more dramatic, deep midnight blue.
6-Foot Cable
Based on feedback from the audiophile community, we updated the HD 6XX with a detachable 6-foot cable (compared to the original’s cumbersome 10-foot cable).
Standard 3.5mm plug
Our community asked for better compatibility with laptops, phones, DAPs, and more—so we opted for an ⅛-inch plug instead of the standard ¼-inch plug.

Classic Sennheiser Sound
The HD 6XX has a smooth, laid-back presentation with a balanced midrange and natural-sounding bass.
Neutral Response Curve
The neutral response provides an excellent listening experience across virtually any genre—from virtually any source.
Open-Back Design
The open-back design offers roomy, auditorium-like acoustics for accurate sound reproduction. However, the design won’t isolate you from outside noise or prevent sound from leaking, so it's best-suited for quieter environments.
A Refined Soundstage
Like the HD 650, the HD 6XX is considered more refined and better damped than its predecessor, the HD 600. It has less energy in the upper midrange and an overall balance that’s a bit warmer and bassier.

The Perfect Intro to Audiophile
Our HD 6XX sounds great out of the box, but there are plenty of ways to customize it even further, along with excellent long-term support from Sennheiser.
Amplify Your Experience
The HD 6XX responds well to improved sources of amplification, and headphone amplifiers of any output impedance will make a great match.
The Right Match
For the objectivist audiophile seeking a complete desktop solution, there’s the Massdrop O2 + SDAC: a DAC/amp that brings two great products together in one affordable, easy-to-use package—available at checkout for $25 off.
Find Your Balance
Designed specifically for our Sennheiser HD 6XX and HD 58X headphones, these balanced cables allow you to plug into compatible 2.5-millimeter digital audio players, portable amps, and the latest devices. Add one at checkout for $10 off.

Kevin, my 6xx's shipped on 9/16. It's now the 22nd (which FedEx said was shipment due date). Not here today either. Frustrating in that it's taken 7 days now to go the 280 miles from PA to Northborough, MA. Yup, that's about 40 miles per day. In 2020. I've received 2 updates. UPS and FedEx both use the USPO as their "Sure Post" service. Which....sucks. Our home gets delivered mail around 3PM. We live 8 houses up the street from the PO. Therefore, we get mail last. So whenever I get these "SurePost" deliveries? UPS will drive right by my house around 3:45. They are taking my package to the PO (remember, 8 houses down) where it'll sit overnight. The next day mail will set out with delivery. I'll get my package some 24 hours after it sits in a place I can practically see. Unbelievable. The PO workers HATE delivering the packages. Also, UPS and FedEx count the drop off at the PO as "delivered". If indeed my headphones are just 8 houses down the road? I won't know anything until 3PM. See, the PO rarely posts any. But according to FedEx, they've delivered the package on their own due date. Even though I am at the mercy of the PO now. It's a terrible idea to basically drop the packages off at the PO. I have to add one, sometimes two additional days onto my shipments because now my packages are in the PO's possession and care. FedEx and UPS have really taken a few big steps backwards. It's maddening to know that my headphones are locked up down the street for another 24 hours. The Pony Express could deliver from PA to ME faster. That's a fact. (I know it's not Drop's fault here regarding what FedEx does but, surely in this day, some other service can eclipse an average of 40 miles per day)
