Get these premium Sennheiser cans for only $437 today

By Michael Bizzaco Published April 21, 2025

Audiophile headphones deliver the decibels like no other, but these premium cans are often mighty expensive. And while $437 may not sound like a steal for the Sennheiser HD 660S2, these premium cans normally cost $600 and are on sale through Amazon this week!

Our own Simon Cohen tested the 660S2 back in 2023 and said, “The Sennheiser HD 660S2 provide rich and detailed audiophile sound for critical listening sessions.”

You shouldn’t buy the Sennheiser HD 660S2 if you want a pair of noise-canceling headphones with a portable form factor and wireless connectivity. The HD 660S2 are strictly wired, which means whatever you’re connecting them to needs to have an auxiliary port. But if you’re willing to find a quiet spot to do some listening in, you’ll be handsomely rewarded. 

The Sennheiser HD 660S2 deliver a warm, bass-forward sound profile compared to previous models in Sennheiser’s over-ear lineage. You can also expect solid midrange performance and a decently sized soundstage. Because of the open-back design, these headphones leak a ton of audio, which is another reason why listening in a distraction-free space is preferred. 

Sennheiser even provides a cloth carrying case with a drawstring to keep your 660S2 free of dirt and moisture. The company is also kind enough to give the must-have cables in the box.
