SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

I listen to MOONRISE by NIGHTTEMPO. Surprisingly, I can feel the waves on both sides beating on the boat.

They sound great and are a work of art. I didnt realize they were so compact and elegant. Used to have a 650 but no comparison. I have 6 pair of headphones now. Not sure if its a hobby, collecting, or hoarding. But I love them all. I encourage anyone to get the NewFantasia cables sold here on Amazon. Brings more life into the listening experience. If you dont have a balanced output on your amp, NewFantasia makes an adapter that has the 3.5mm or 1/4 option for plugging into your cans and the amp. They are priced fairly and add so much to the 660s and all my cans.

I received the Headphones in a damaged box, it looked as if they had been previously returned by another Customer.

Great Mids and Highs, lacks sub bass. Needs amplification to sound its best.

Neat, comfy, and pretty good entry for a newbie like me to hifi audio. Its plain bread and butter and I am fond of the simple stuff. Nothing jumps at you sound wise yet nothing is lacking either.

The amount of detail in these are very impressive. A punchy but balanced sound signature will keep you engaged in all kinds of music. Open-back design creates very immersive sound staging, but sound VERY easily bleeds through as a cost. For gaming, these are great headphones, just keep in mind that your mic may pick up noise if you play on high volumes. For music, I have no complaints. No discernible distortion at various volume levels after first few days of listening, and these arent even broken in yet. I highly recommend if you have not owned high-end headphones yet, and if you enjoy hi-fi audio. I also recommend a quality amp to unlock the full potential of these headphones.

Great headphones for the audiophile that wants quality entry-level, open-back headphones without breaking the bank entirely. They also make decent gaming/conference headphones due to the open back headphones since they allow you to hear yourself due to the open-back design.

I really was excited to get these headphones and wanted to love them but they have a muffled flat sound. My Grado SR60s have a fuller sound and cost about a fourth of what these cost. I am most likely going to send these back.

I purchased Sony MDR-7506, which sound great especially for the price. However after use for several weeks, they were not very comfortable and got warm with extended digital piano playing due to closed back.

good sound quality
