Sennheiser HD 660s Audiophile Headphones
It's a good choice for me to play games and listen to music!
Really enjoy this headphones especially with acoustical music.
Great sounding cans, I love the wide sound stage and there is plenty of detail in them. Cant beat them if you can get them on sale like I did.
My New Daily Drivers
These are quite literally the best headphones I’ve ever owned. Comfortable as heck and the sound signature is exactly to my liking. They are the best of the Senn 600 line IMO and the detail retrieval is out of this world. Vocals are buttery smooth. High recommend!
An upgrade from HD650 better extended in the treble region, no veil and better soundstage are all attributes the 660s has over HD650. An overall better presentation over all the HD6 series cans. Definitely an upgrade.
