SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

Excelente calidad de sonido, cómodos, muy buena construcción, muy recomendables

These headphones clamp a bit too hard on my head and not super comfortable. They do sound pretty good especially considering their relatively low price. That said, I ended up sending them back - I prefer Grado 325s for general music listening and HiFiMans HE6ses for acoustic and jazz. Funny story: the clerk at the Whole Foods Amazon return desk couldnt believe I was returning them ;)

As far as I know, the post mid-2021 manufactured HD660S are made in Ireland (again), as printed on the box, which is accurate for importing purposes. However, Sennheiser Ireland continues to use the same modeling from post-2019 Romanian units, which the “made in Ireland” labels are replaced with CE labels…

Amazing neutral sound, vocals are just perfect. The sound is very flat and accurate. Great pair of headphones for music and pc gaming.

Best open headphones! Recommended for sure!

Of the 5+ headphones I own these are the most comfortable (I can listen for hours) and best sound. Because the are open backed they are best used and home where I will not effect others sound space.Out is the public I listen to closed back or IEM’s for music solitude.

Comfortable. Good sound, but not 4x better than my Audio Technica M50x, or even M40x. I understand the audiophile, you always wonder if you’re missing out on better sound. You think paying more will get you there. Not always.

Great build quality, sound stage is top tier.

Im no audiophile or anyone that knows anything about impedence and ohms, but it plays at full volume through my S20 ultra, and the ability to actually hear where something is and what it is, is really amazing. They sound fantastic. I love them

Firstly, I gave them 1 star for noise cancelation as they’re open back... not sure why thats a category for a review for this kind of headphone. Id like to say I’m not an audiophile and I dont have high end audio set up. I use these with my little dot mk3 headphone amp.
