Fantastic Headphone for the Price

This was practically brand new upon opening the package. I don't notice any cosmetic damage to it, and they perform really well with no defects. It came with all the accessories, and they all appear new as well. Overall, I'm really happy that I chose to purchase these refurbished.

Box damaged. Headphones as good as new from the looks of it.

Great Deal

The HD660S were my 3rd pair of high end headphones, and my first pair of refurbished headphones. I was a little unsure of buying refurbished headphones but they seem like they’re brand new. The packaging had clearly been handled but was in very good condition. If you’re on the fence about headphones and looking at a refurbished pair from Sennheiser it’s a no brainer. I’m very happy with my purchase.

Headphones are amazing

These are truly some of the best headphones an amateur audiophile could get. These headphones are a leap forward from the traditional Bose and Sony headphones. The sound is so clear and vibrant that music, movies, and videogames sound so much better.

Just what I’d hoped for

These headphones were bought as part of a project to upgrade my audio system. I’d not put any new investment into the system for a very long time and one day realized how far things had moved ahead, particularly in the availability of high quality source material. My serious listening sessions have always been done through headphones, so I purchased these 660S phones, followed by a dedicated headphone amp (my old phones were power amp-driven) and stand-alone DAC. It was transformative. The clarity, detail, and fullness of high resolution files is wonderful, and these headphones bring it all out to enjoy. Now, I’m not a guy who’s going to travel around and try to compare various headphones. Instead, I do extensive research, pick a target, and pull the trigger. So I can’t describe these headphones in comparative terms. But in absolute terms, these headphones’ performance with high resolution source material is the huge step ahead that I hoped it would be. I need to also mention that they are extraordinarily comfortable through long listening sessions.
